Of course, buying new radiators is a very expensive pleasure. And what about the owners of old, Soviet cast-iron batteries? of course, paint them. Thus, you can create your own individual interior. Painting is best done in the summer, when the heater is cold and the smell from the paint will quickly disappear.

What to do if there is an urgent need to repaint hot batteries? This can be done, but the quality of work will be poor and it will be troublesome.

In order for the work to be done as it should, and in the future there would be no problems, we advise you to take into account some of the nuances:

There are two ways of processing heating devices: a mechanical method and a chemical one.

1. The chemical method of processing consists in the use of special chemicals that are able to dissolve the old layer of paint and remove it without much difficulty. Do not forget about security measures. When working with chemicals, you must wear gloves and goggles.
2. The mechanical method or “manually” is based on the use of sandpaper, scrapers, drills with special nozzles.

So is it still possible to paint hot batteries? Of course you can, you just need to choose the right paint. Once again, read the label on the jar carefully.

High-quality paint for painting batteries will cost about three hundred rubles. A good hardware store can tint you if you wish. Usually they charge fifty rubles for this.

So get down to business boldly. We hope that our advice will help you in ennobling radiators in an apartment or house.

How to paint a heating battery: the nuances of the process Paint for heating pipes - which option to choose? Humidifier on the battery - features of modern options

How to paint a heating battery? - For those who have old cast-iron "harmonicas", this question worries literally every 2-3 years. Sometimes people think about this, who, during the current repair, suddenly discover that the color scheme of the radiator does not fit into the color concept of the room at all. Every year, on the shelves of construction stores, the range of paint and varnish products increases and it becomes more and more difficult to make the right choice. In this article you will find all the necessary information about what paint to paint radiators on old paint, how to do it, and whether this decision is always the right one.

• It is undesirable to paint modern aluminum and bimetallic batteries. Initially, they are painted at the factory with resistant powder paint, which, thanks to the peculiarities of the technology, lays down perfectly evenly. If you decide that the original color of the radiator (usually white) does not match the interior of the room, and you want to repaint it, then you are unlikely to be able to achieve the same perfectly even coverage. Even if you dismantle the battery and cover it with paint in a horizontal position. In addition, an additional layer of paint will reduce heat transfer, which is a significant disadvantage for regions with severe winters.
• It is undesirable to paint plate radiators, especially those with a large surface area. They are installed in houses where a network with increased internal pressure passes. They have low convection but high heat transfer. As for our question, due to its design, it is difficult to paint a heating radiator of this type with high quality, especially with a brush. If it is really necessary, then you will have to take it off, clean it thoroughly (which is very difficult) and paint it in a horizontal position with an airbrush or spray car paint. But even so, you may not achieve a perfect application. Missing areas may remain in hard-to-reach places, because the elements of the plate radiator are too close to each other.

• Convectors, tubes with fins (especially with frequent aluminum fins) are not painted, because painting can adversely affect their heat transfer. The design of the convector, in addition to the heat source, includes a removable casing. It can be painted to enhance the overall look.
• It is recommended to paint cast iron batteries. This is not difficult to do, the colors are different and they do not affect heat transfer. The choice of color is huge.
• Painting of steel panel radiators is possible. But there is a nuance here - it will not work to evenly cover the surface of the battery with a brush. You will have to use automotive paint in a spray can, and it is advisable to paint in a horizontal position.

Important! In order to bring the battery as close as possible to the desired color and color scheme of the room, it is recommended to use decorative panels. They are sold in hardware stores and online stores. They can be made from wood, metal, plywood, plastic and even glass. These screens come in different shapes, colors and sizes. Figured carving, patterns, photo printing and more can be applied to them. So the choice is great, and you can pick them up for any, even the most sophisticated interior.

1. For painting a cast-iron radiator - straight and curved soft brushes, no more than 5 cm wide.
2. For painting a panel radiator - a foam roller of small width.
3. Paint in cans or spray.
4. Paint bath (if the paint is not aerosol).
5. Special paint remover (if you decide to get rid of old paint by chemical means) and a metal spatula.
6. Drill with a nozzle in the form of a metal brush for stripping the battery from paint residues.
7. Solvent.
8. Gloves, goggles, respirator or gauze bandage, protective clothing.
9. Newspapers, oilcloth, cardboard, masking tape to protect surfaces.
10. Rags.

What paints are suitable for painting a radiator?

During the repair process, we think about how to paint the heating battery without smell, without streaks and streaks, so that the paint dries quickly and the beautiful appearance of the device is preserved for a long time. At the moment, there is no such ideal paint yet. However, there are several options for obtaining the optimal result.

For painting the radiator may be suitable:

• water-dispersion and water-based paints;
• alkyd enamel and auto enamel;
• acrylic paint;
• oil;
• silicone-aluminum paint;
• silver.

Let's consider each option in more detail.

Oil paint

Regarding this type of paint, we will immediately make a reservation that theoretically, of course, it is suitable. But in practice, it is almost never used for painting batteries:

• Its biggest disadvantage is that it dries for a very long time. This process can take up to a month, you see, it is not very convenient.
• In addition, oil paint has a rather unpleasant odor.
• It is difficult to paint the surface evenly, without streaks and sagging.

Important! In view of such significant shortcomings, it is recommended to choose another option for these purposes.

Water-dispersion and water-based paints

Water-dispersion paint is made on the basis of polymers and water dispersion. Its main features:

• It is moisture resistant and can be washed.
• Diluted with water.
• Mainly available in white.

The water emulsion is made on a water basis, and it:

• It can have many colors and shades.
• Not so resistant to abrasion, can be slowly washed off when in contact with water.
• Diluted with solvents (eg white spirit).

Important advantages of this type of paints are:

• their environmental friendliness and safety;
• absence of chemical odors during application;
• ease and simplicity of painting;
• the possibility of tinting;
• a wide range of application tools and affordable cost.

Important! The only negative is that the surface must be primed before painting, otherwise the water in the composition will cause rust.

Alkyd enamel and auto enamel

Alkyd enamel is one of the best options for painting a radiator. It behaves well at high temperatures (withstands up to 100 degrees), with temperature extremes, is resistant to abrasion and has many colors.

Regarding its capabilities:

• This type of paint is sold everywhere and is relatively inexpensive. This is the familiar PF-115 and its imported counterparts (manufactured by ACE, Dulux, Sigma Coatings and others).
• A significant disadvantage is the persistent chemical smell, which disappears for a long time after applying this paint to the battery.
• In addition, poor-quality enamel may turn yellow over time.

Auto enamel also has a persistent unpleasant odor, so the room will then have to be ventilated for a long time. There are other nuances of application if you need to paint the heating battery:

• Applying paint from a can is quick and easy, but this, of course, requires skill so that the paint layer lays down evenly.
• With this application, unpainted areas may remain, and it is also necessary to carefully cover all surfaces surrounding the radiator from splashes.
• Auto-enamel has a glossy sheen, it will give out and emphasize all surface irregularities.

Acrylic paint:

• Acrylic paint is also water based.
• It practically does not smell and has an affordable price.
• The basic base is white, but if this color does not suit you, you can tint it in any other shade.
• The temperature limit of acrylic paint is +80 degrees - this is quite enough for average radiators.
• She dries quickly. It takes less than a day to apply 2 coats and it's all dry.
• It does not turn yellow over time, but also requires preliminary priming in order to avoid the appearance of rust.
• After drying, acrylic paint forms a polymer coating that is resistant to washing.

Silicon aluminum paint:

• Perfectly lays down on any surfaces, forming a dense layer which narrows and expands together with metal.
• It withstands temperatures up to 500 degrees, does not require pre-priming, is easy to clean by any means and does not lose its visual appeal for a very long time.

Important! This paint is one of the most expensive. Another disadvantage is the corrosive smell, which disappears for a long time.

Serebryanka

Known since Soviet times. On the shelves of hardware stores are its modern counterparts. For example, heat-resistant paint BT-177.

How is it different:

• It consists of varnish mixed with aluminum powder.
• Silverfish is inexpensive, but also has an unpleasant odor.

Color selection:

• If you just want to update the look of the radiator without significant expenses, then paint it white. White and silver are classics of the genre.
• If you want the batteries to be inconspicuous and fit into the decor, you can paint them to match the walls.
• In a children's room, a radiator can be made part of a fun interior - cover it with bright paint or even make the sections multi-colored. You can apply patterns to the batteries with a brush by hand or using a stencil. It is possible to decorate the radiator with decoupage.

What paint to paint the radiators - you already know, now let's get down to the process itself. It can be divided into two stages:

• preparation (cleaning of old paint);
• applying paint.

cleaning

Ideally, for high-quality cleaning, the radiator must be disconnected and the remaining water drained, since it will be difficult to get from the back side. We will miss how to wash the battery from dust and dirt, everyone will cope with this without additional advice. But there are several ways to clean up old paint.

Method number 1

The simplest and easiest method is to use a special wash. This chemical is sold in all hardware stores. But it is suitable for processing only cast-iron radiators, since cast iron is inert to this substance.

Procedure:

Method number 2

The second cleaning method is carried out using a building hair dryer or a gas burner.

Important! This method is not suitable for cast iron, as the process will take a long time and will be ineffective.

Procedure:

1. The essence of the method is to heat the paint layer to high temperatures with the device, and then scrape it off with a spatula or a stiff brush, without waiting for it to cool.
2. It is desirable to carry out such work in the open air, therefore, of course, the battery must first be removed. If this is not possible, protect the surrounding surfaces with plywood and open the windows.

Important! This method can damage the gaskets in the radiator, so be prepared for the fact that they will have to be replaced with new ones.

Method number 3

Another thermal method is processing the battery with a fire. The old “old-fashioned” method is laborious, but it allows you to clean the battery not only from the outside, but also from the inside.

Procedure:

1. Remove the radiator, unscrew all plugs and other parts.
2. Disassemble the battery into sections using a radiator key (the sections are connected by nipples with opposite threads).

Important! If this did not work out immediately, then you can do it after firing.

1. Build a good fire in the yard and put a radiator in it. Maintain the fire for about an hour, longer if possible.
2. After removing the battery from the fire, clean it with a metal brush, this process will be easy and fast.
3. After that, tap each section with a mallet to shake out all the rust accumulated over the years from the internal channels.
4. Now it remains to reassemble everything using new rubber gaskets.

Important! Gaskets can be cut out of an unnecessary car inner tube.

1. Wipe the radiator from dirt and degrease.

Method number 4

You can also use the mechanical method:

1. Put on a drill (grinder) nozzle - a metal brush or an emery wheel.
2. Treat the surface of the radiator.

Important! The disadvantage of this method is that it is difficult to reach many places with a tool, so the work will have to be finished manually, using a stiff brush and sandpaper.

1. As in the previous methods, the surface should then be cleaned of debris and degreased.

Painting

When asked whether heating radiators can be painted hot, experts answer in the negative, because most paints will not fit well on a hot battery. Painting is best done outside the heating season. If there is no way out already, then paint quickly, without picking up a lot of paint on the brush and then it, shading it with a thin layer. Or shut off the supply of boiling water to the radiator and wait for it to cool, then paint.

Important! During the dyeing process, remember to protect your eyes, hands, and respiratory organs from paint splashes and toxic odors.

After cleaning and degreasing, we proceed to the most important thing - painting. The procedure will depend on the type of dye chosen.

Acrylic and water emulsion

If your choice fell on acrylic or water-based paint, the radiator should be primed with an anti-corrosion compound, otherwise rust will appear over time.

Important! On sale there are paints in which the primer has already been added.

can paint

If you paint the battery with spray paint, then the technology is as follows:

1. Start in hard to reach places, and then move on to the front.
2. Move from top to bottom in zigzag movements, not stopping in one place, otherwise the layer will lie unevenly.
3. It is recommended to cover the surface with two layers, so after the first has dried, proceed to the second.

Important! You can take the radiator to the service station for painting, where specialists will do it professionally.

With the help of a spray gun

Painting with an airbrush takes place in the same way as in the case of spray paint.

Important! To reach all areas, it is better to paint the battery in the removed form.

Liquid solutions

If you paint with paints in liquid form, then protect the surrounding surfaces with oilcloth, as well as newspapers:

1. Pour the paint into the paint bath and with a curved brush, first coat all interior and hard-to-reach surfaces.
2. After that, with a straight brush, begin to process the front part, moving from top to bottom.

Important! Take a little paint on the brush, the layer should be thin, otherwise streaks will form.

1. After the first layer has dried, cover with the second. Two layers are usually sufficient.

Important! Acrylic paint and water-based paint dry quickly and without much odor, you can handle it without problems in a few hours. But alkyd enamel will dry out for more than a day and emit an unpleasant odor for a long time, so we recommend painting the radiator in the summer, when it is possible to open windows for a long time.

That's all the wisdom regarding the choice of paint for the heater and the process of applying the coloring matter. Using the useful information from the article, you can do everything correctly and with minimal losses. You can be sure that by successfully updating the old battery, the interior of the room will improve.

What should be the paint for batteries

A feature of any battery is that in operating mode it always heats up to a high temperature. Of course, the degree of heating depends on the temperature of the coolant and other additional factors. Regardless of whether, along with cast iron, steel or non-ferrous metal, the paint that is planned to be applied to the heating device will also heat up.

And so that the paint for heating radiators does not “please” with an unpleasant odor, harmful substances released into the air, as well as the loss of its solidity, it must:

• withstand high temperatures;
• do not contain toxic substances;
• do not emit an unpleasant odor when heated;
• be resistant to aggressive environments and abrasion.

Types of dyes for batteries

The above requirements are met by many types of paints, or rather individual representatives of these types. After all, most paints are designed for temperatures below +80 ° C. Therefore, manufacturers produce special modifications of their products.

In general, do-it-yourself painting of batteries can be done with the following types of paints:

1. acrylic enamels. They are based on organic solvents. This feature causes the release of the smell of the solvent during the application of the acrylic mixture to the battery. However, after drying, this smell becomes history, and a radiator with a pleasant glossy sheen appears in the room. This brilliance lasts for many years.
2. Alkyd enamels. They are known for their excellent resistance to wear and high temperatures. The range of colors of these enamels is very large, so many opt for such paints. These dye solutions also give off an unpleasant odor while drying. It can also be felt in cases where the heating radiator heats up very much.
3. Water-dispersion paint. Many experts note that such paint for radiators is optimal. This is because it does not upset the nose with a specific smell, and the drying time is very short. True, not every water-based mixture is suitable for batteries. Only the one on the packaging of which there is a corresponding designation is suitable. Its color can be any.
4. Oil paints. They were very popular in the past. Known for emitting a solvent odor at the time of drying and a long curing time.

It is worth adding that paint for a radiator may contain elements that resist corrosion and improve adhesion (they are constantly used in primers). Such mixtures have a different color, do not require primers and cleaning the radiator from corrosion.

At least that's what the manufacturers say. In practice, it is better to remove the rust of the heater and use a primer. The processes are long, however, the result is reliable. This is often noted in various videos.

Applying paint to a heating device

It seems that this process is quite simple, but it requires proper execution. Painting radiators includes the following steps:

1. Cleaning off old paint.
2. Removal of corrosion.
3. Degreaser treatment.
4. Applying a primer.
5. Do-it-yourself application of several layers of dye of a certain color.

The first four points are preparatory.

Features of preparation

There are two ways to remove a layer of old paint:

1. Mechanical.
2. Chemical.

The first involves the use of a spatula or a round metal brush attached to an electric drill. Working with a spatula requires physical effort, since they need to be moved by their own hands. Moreover, it will take a long time to wash the paint. This must be taken into account in calculating the total staining time. The disadvantage of this option is that it is difficult to reach the bottom of thin slots.

A round metal brush mounted on an electric drill is a more versatile method. It is able to process almost the entire area of ​​​​the radiator, including many hard-to-reach places. At the same time, the time of work and the physical effort spent will be very small. Most people like this, including those who do the calculation of the repair time and shoot videos of the process.

The chemical method involves the use of special solvents or fatty acids. They process the entire area of ​​\u200b\u200bthe battery and cover the treated surface with a film. Then they rest. The duration of the rest is indicated on the package. It may be different. During it, the paint becomes soft. Of course, it does not slip (and it would be very good), but its removal with a spatula, grinder or wire brush becomes very easy.

It is worth remembering that solvents emit substances harmful to the body. Therefore, when using the chemical method, you need to protect your hands with construction gloves, the airways with a gauze bandage, and even better with a respirator.

The surface of the radiator, cleaned of paint, is treated with sandpaper. They work especially carefully in places where there is corrosion. It needs to be completely removed. Only a pure metallic sheen should remain.

For degreasing use white spirit or any other alkaline solution.

The primer of the radiator is carried out with a solution that meets the following requirements:

• is a product of the same manufacturer that produced the paint. In this case, the primer and paint are best suited to each other;
• contains substances that can resist corrosion.

Features of applying paint

Before painting, the heating radiator must be cooled. This is because most paints are designed to be applied to a cold surface. If they are applied to hot metal, they will dry quickly. And this will not allow you to apply a uniform layer and correct smudges, stains and stains in time. In any case, under the condition of working on hot batteries, the time for applying paint becomes very short. In this case, the mistake made may remain uncorrected. This is often noted in different videos.

True, there are some exceptions. So, people who ask the question whether it is possible to paint hot batteries should pay attention to paints specially designed for this purpose. They are able to dry on heated metal very slowly. However, such paints are quite expensive, and the final result of calculating a small repair will be a considerable amount. Therefore, it is better, before painting the radiator in winter, to turn it off and wait for it to cool. It is best to change the color of the heating device in the summer season. Then it is convenient to ventilate the room and the batteries are cold.

If you have to paint a cast-iron heater during the heating season with ordinary paints, then you need to apply a very thin layer of paint. Apply two such layers.

The application of a coloring mixture of a certain color occurs in the following sequence:

1. Placing oilcloth or old pieces of newspaper under the radiator.
2. Applying paint to the top. Then they gradually go down. Thanks to this, such a problem as smudges is eliminated. First, the coloring mixture is applied to the internal parts of the device, and then to the external ones. You need to paint the entire surface.
3. Drying of the first coat of paint.
4. Apply the second layer in the same way as the first.

The battery is covered with paint using various tools, namely:

1. Brush.
2. Airbrush.
3. Spray can.

If you plan to use a brush, then you should take several of its options. The first should have soft, straight bristles. The other has curved bristles. Thanks to the second, you can work out with your own hands those places to which access is limited.

In the case of painting with an airbrush, it is better to remove the battery. So excess paint will not get on the walls. In addition, there is a great opportunity to paint the most inaccessible places. Spray painting is very fast. In this case, you need to perform zigzag movements. They move from top to bottom. The distance from the treated surface to the spray can should be 30 cm.

How to paint a heating battery: recommendations and photos

It is worth immediately clarifying that painting heating radiators is not possible in all cases. First of all, it is advisable to perform this operation for cast-iron radiators, on which a thick and uneven layer of paint not only spoils the exterior of the battery, but also greatly impairs the quality of heat transfer. The second type of batteries that can and should be painted are convectors made in the form of a bent riser pipe with fins pressed onto it.

Painting cast iron radiators

If you are the owner of modern models of radiators with aluminum sections, then it is better to refuse the idea of ​​painting. Of course, you can paint it, but you will have to apply many layers of paint, and you are unlikely to achieve the expected effect. The fact is that the battery is painted with a brush, and this method, by definition, is worse than the factory one, so it is better to leave the new battery models alone, and if necessary, cover them with a decorative screen.

Brushes for painting radiators

Before proceeding to the main stage of work, you need to prepare. First, prepare soft brushes, which should be small in size and of two types - straight and curved. The straight brush is intended for painting external, easily accessible areas, and the curved one is for painting the rear and internal surfaces of the radiator.

What paint to choose

The main role in this work is played by paint for radiators, which can be of the following types:

• water-dispersion;
• alkyd;
• acrylic;
• oil.

Any paint for heating radiators must be resistant to abrasion, tolerate high temperatures (up to 100 degrees) and not emit toxic compounds when heated. In these parameters, the above options differ significantly from each other. For example, water-dispersion paints do not have an unpleasant odor and dry quickly, but this type of coating is less resistant to abrasion than others, that is, it will have to be updated more often.

Special alkyd enamel VD-AK-1179 for radiators

Acrylic paint has a chemical solvent in its composition, therefore, when used, an unpleasant odor is emitted, which takes a long time to weather out of the room. The advantages of such a coating are high abrasion resistance and an attractive glossy appearance.

Alkyd paint for radiators also has an unpleasant odor, but is in high consumer demand due to its high abrasion resistance and a huge range of shades. In addition, the smell from modern building materials is not so pungent.

As for oil paint, it is used less and less as a coating for radiators and pipes. The reason for this is an unpleasant odor, a long drying time and the difficulty in applying an even layer.

How to paint radiators is up to you, but it is best to use alkyd paints from well-known manufacturers. You just need to choose the right color for the cover.

What paint to paint radiators video

How to paint radiators: preparatory stage

So, the materials are selected. Now you can proceed to the preparatory stage. Old cast iron radiators can have paint chips and many layers on top of them, so you need to completely clean the radiator from the old paintwork to the metal. This operation can be performed using a hot air gun, which melts the old paint with a jet of hot air, after which it can be removed with a spatula.

Cleaning pipes and batteries with a grinder with a special nozzle

If there was no mounting hair dryer at hand, then you can use an alternative option - a flushing solution. This solution is applied to the entire surface of the radiator, after which the heating device is covered with a film. After an hour of action of the cleaning solution, the paint can be removed with a spatula.

The main layer of paint has been removed, now we clean the battery from its remnants with fine emery or a special wire nozzle for a screwdriver. Then we degrease the surface of the radiator with a rag soaked in a special solution, such as white spirit. The final step is to cover the radiator with an anti-corrosion primer, which will protect the radiator from corrosion, but will also improve the adhesion of the paint to the surface.

Painting a heating battery: basic rules

It is immediately worth clarifying that the painting of the batteries should be done with the heating turned off. This limitation is due to the fact that the paint dries very quickly on a hot surface, which can lead to an uneven coating layer and smudges.

How to paint a heating battery after stripping

Before painting the radiator, lay an oilcloth or rag under it, which will protect the floors from paint getting on the floor. Start painting the radiator from hard-to-reach parts with a curved brush, and cover the front side with paint at the last moment. This approach will allow you not to smear the newly applied layer of paint, and your hands will remain clean.

Spray painting aluminum radiators

In order for the paint for the heating battery to lie evenly, it must be applied in two thin layers. To apply the second layer, you need to wait for the first to dry completely.

Possible painting problems

During the implementation of each stage of work, unforeseen difficulties may arise - the paint falls unevenly or the old coating is not removed. In order not to spoil the materials, you can pause work, wait until it dries completely and start again by cleaning and degreasing the surface.

You can find out what paint to paint radiators with consultants in a specialized store, they will help you decide on a specific brand that is most popular among buyers.

To avoid additional difficulties, pay attention to the video instruction, where experts will help to study the painting algorithm in detail and follow the detailed steps.

Outcome

Painting radiators plays an important role, as this element of heating attracts attention and is a subject of interior and design of the room. Using the above tips, you can ensure that the old cast-iron battery after processing will look no worse than the new one, and the coating will last for many years.

Choosing an odorless paint for radiators

The choice of paintwork for the heating system is a rather relevant and undoubtedly important issue. The paint must meet the objectives: withstand high temperatures, maintain gloss for a long time and not snap off. But this is its functional and aesthetic load. But the question of what kind of odorless paint for radiators and how to paint them sometimes remains open. An informative excursion into the world of paints and varnishes will help to understand.

Which one is better to choose

The choice of paint for the heating system of an apartment or house is closely related to the material from which the batteries are made. Each of its types has certain properties that are friendly to the paintwork or conflict with it. The main types of materials used for the production of radiators:

• cast iron;
• bimetal;
• steel;
• aluminum.

For painting heating radiators, the market of manufacturers offers a wide range of species and a rich palette of coatings:

№	Varieties of coatings	Kinds painted radiators	Advantages	Flaws	Firm- manufacturer
1	Oil paint	Cast iron	Wide color palette	Dries for a long time, has a persistent smell, quickly fades, cracks, loses shine	"Tikkurila", etc.
2	Serebryanka	Cast iron	Excellent high temperature resistance	Persistent odor	"Lacra", "Gloss", etc.
3	silicate paint	Cast iron	Designed for high temperatures	Long lasting odor	"Nevbytkhim", "Ceresit", etc.
4	Powder paint	Any kind	Durability, resistance to damage and high temperatures	Coloring in professional cameras	"Triton", "Ral", etc.
5	Alkyd enamel based on organic solvents	Cast iron, steel, bimetal	Rich range of applications	Characteristic smell, color varies by pigment	"Olecolor", "Enamel", "Tex", etc.
6	Water based alkyd enamel	Any kind	Barely pronounced odor, no color loss	Titanium white is added to the high-temperature paints of this series, which are not cheap.	"Tex", "Lacra", "Enamel", etc.
7	Alkyd hammer enamel	Cast iron, steel, bimetal	Hides paint imperfections	There is a faint smell, which disappears after drying	"Olecolor", "Tex", "Enamel", etc.
8	acrylic enamel	Cast iron, steel, bimetal	Almost no smell, dries quickly, wide range of colors, durability	It is required to carefully prepare the surface to be painted: sand, prime	"Lacra", "Rainbow", "Tex", etc.
9	Paint in cans	Any kind	Wide range of colors, ease of dyeing process	Strong smell	"Kudo", "Decorix", "Newton", etc.

Can it be hot dyed?

The opinions of experts on the issue of painting radiators differ: some argue that they need to be painted to protect them from corrosion. Others retort that the application of one or another type of enamel on radiators does not perform any protective function and is purely aesthetic in nature. Another thing is painting pipes in winter when the radiators are hot.

Paints and varnishes suitable for the heating system and withstanding high temperatures require painting on cold batteries. If the radiators are covered with enamel on a hot surface, then the paint will dry “on the fly” and the quality of the coloring will get out of control: sagging and unsightly spots will appear.

It would not be superfluous to recall that when covering a hot radiator, the smell of paint will increase, and opening windows in winter for ventilation is problematic due to the cold.

Important! Consumers most often choose the white color of the battery coating, but experts say that the dark tone of the radiator color contributes to better heat dissipation.

The painting process

Before proceeding to the stage of applying paint, you need to stock up on the necessary equipment:

• radiator brush (curved, with a long handle);
• regular brush (100 mm wide);
• rubber or silicone gloves;
• respirator (if paintwork is odorous);
• newspaper (to protect the floor from paint stains);
• sanding sheet No. 2 (if necessary, cleaning the batteries from irregularities);
• rag;
• primer;
• dye;
• white spirit (for unexpected skin contact with paint).

Sometimes, the preparatory work takes more time than the staining process itself. This is not surprising, because the radiator has a lot of hard-to-reach parts that need to be washed, and in some places peeled off paint and sanded.

Important! If there is a desire to remove the old coating completely, then you can use a special wash.

1. Prime the prepared surface.
2. In order to avoid drips, painting starts from the top of the heating system.
3. The internal parts of the batteries are also coated first.
4. Layers of paint are applied evenly in a thin layer.
5. As the paintwork material dries, the radiators are repainted.

Stages of painting a radiator

Technology of painting on old paint

The condition of the paint on the heating system can be different:

1. The coating, although old, faded, but has a monolithic adhesion to the base. It is enough to sand the surface a little with sandpaper for reliable adhesion of the next layer of paint.
2. The old coating is worn in places, peeled off and metal is visible in places. Here, a more thorough grinding of the surface will be required so that chips and irregularities do not show under the new layer.
3. The paintwork is hardened, flaky in large areas, rust shows through in places. Such paint must be mercilessly removed with a metal brush or special preparations for washing. The prepared surface is primed before applying the first layer of paintwork materials.

Important! You can simply update the old paint: apply a fancy pattern to it, after sanding, for better adhesion.

For the convenience of consumers, paint and varnish manufacturers produce an aerosol coating for radiators. It has excellent properties:

• withstands high temperatures;
• easy and quick to apply;
• dries almost instantly;
• has a pronounced gloss;
• adheres well to any surface.

The only negative is a strong smell, but it will disappear in just an hour.

Balloon paint is sprayed onto the surface to be painted from a distance of 30 cm. The movements should be smooth, but fast, in a zigzag pattern. Depending on the quality of the surface of the heating battery, it may be necessary to paint in several layers.

Important! When working with aerosol enamel, it is necessary to cover a large area around the radiator with newspapers, because. skill in painting with spray paint will not come immediately.

Having the necessary information about the coatings of radiators, you can get useful tips and learn about the features of the technologies for using paint and varnish products.

Heating batteries, like it or not, are very often an integral element of the interior of the premises, which means that they need a certain decoration and regular maintenance. In order for the heating radiators to look neat, to serve trouble-free for as long as possible, and the paint layer to hold securely on them, without cracking and peeling, despite high temperatures, it is necessary to use special heat-resistant paints and varnishes for these purposes.

Which paint for radiators is better to choose - this question arises for all homeowners who decide to upgrade old heating appliances or are preparing to install new ones purchased unpainted. To understand what you need to pay attention to when buying a paintwork material, you need to consider the requirements for them.

What criteria must meet the paint for heating radiators

The compositions for painting radiators and heating pipes are somewhat different in their parameters from conventional paints, therefore it is worth familiarizing yourself with their main physical, technical and operational characteristics, which experts recommend paying special attention to.

• First of all, the paint must be safe for the residents of the apartment or house, that is, it must not emit toxic fumes during the entire period of operation. Therefore, when buying, it is necessary to study the composition of the paint and its compliance with accepted standards and norms. Imported paint from European manufacturers, whose brands are presented in a large assortment on the Russian market, must comply with European standards, and domestic products must comply with the standards of the current GOST. If the package contains a link not to standards, but to some mysterious technical specifications (technical specifications), then this can be considered an “amateur” of the manufacturer, and it is better to refuse such paint right away - its compliance with safety standards is not guaranteed.
• The heat resistance of the paint should not be lower than +80 degrees, otherwise it may crack, peel off or turn yellow. Moreover, this indicator should be considered the minimum allowable - it is better if it is even higher.
• It is desirable that the paint composition be quick-drying - this factor will significantly speed up the work, since the paint is usually applied in two layers.
• The anti-corrosion properties of the paint will protect the surface of the radiators from external aggressive influences. This is usually taken into account in the production of compositions for coating metal surfaces.
• Some paints emit a sharp unpleasant odor until completely solidified - they can be chosen only for those rooms that can be thoroughly ventilated.
• Moisture resistance for radiator paint is necessary for the possibility of unhindered wet cleaning with the use of detergents.
• The thermal conductivity of the paint layer must be high enough, otherwise it will reduce heat transfer from heating devices.

Types of compounds used for painting appliances and pipes of the heating system

For painting radiators and pipes of the heating circuit, paints are produced on different bases. Each of them has its positive and negative sides, and they must also be kept in mind so that these moments do not turn out to be unexpected.

Varieties by base and component composition

So, heat-resistant paints can be oil, alkyd, water-dispersion (acrylic or silicone) and powder.

Oil paints

They are made on the basis of various organic oils, and not so long ago it was practically no alternative for painting radiators. Such paints have a high hiding power, creating a dense and durable layer on the surface of the batteries, resistant to various mechanical stresses and well withstanding high temperatures.

However, in our time they have been practically abandoned, since many other compositions have appeared that are devoid of significant drawbacks inherent in oil paints:

• These paints have a rather unpleasant specific smell, which not only accompanies the process of painting and drying surfaces, but can also appear during the operation of the batteries, with very strong heating of the radiators.
• The density of the layer formed on the radiators significantly reduces the useful heat transfer of the sections.
• There is a certain difficulty in applying the composition on such a basis - unlike other paints, it is difficult to apply an oil paint in a perfectly even layer.
• When applying too thick a layer, the paint may begin to crack and peel off during the operation of heating devices.
• Over time, surfaces lose their luster and begin to turn yellow.
• The oil-based paint coating does not preserve the metal well enough from corrosive processes and quite often you can see rust that has appeared on the surface of the batteries.
• Oil paint is characterized by the longest period of complete drying, and when applied it is very difficult to avoid smudges.

In a word, numerous shortcomings clearly outweigh the advantages (the main of which is affordable cost). It is difficult to call such paint a good option for heating radiators.

Alkyd enamels for radiators

Alkyd-based heat-resistant paints consist of a dispersion of pigments and special additives mixed in pentaphthalic or glyptal varnish. They are quite popular, as they have a number of advantages that allow you to reliably protect the surface of radiators from external negative influences, as well as give them a neat and aesthetic appearance.

Almost all heat-resistant alkyd enamels perfectly withstand the highest temperatures that even theoretically can occur in the heating circuit - this performance parameter is usually indicated on the product packaging. The surface painted by them has perfect smoothness and even gloss, the paint layer does not turn yellow and does not peel off over time.

Alkyd enamels have a fairly high wear resistance, are produced in various colors, which allows, if desired, to choose the right color for the overall interior of the room.

However, despite the listed advantages, such compositions also have their drawbacks:

• Alkyd-based paints, which include white spirit, have an unpleasant pungent odor. It persists not only for several days after staining, but can even appear at first if the radiators are heated too much;
• A sufficiently long waiting time for each of the layers to dry can increase the period of painting work to several days.

Alkyd enamels are also available in the form of aerosols. However, one cannot fail to say that covering batteries in this way is not so simple as it might seem at first glance.

Acrylic heat-resistant enamels

This type of paint and varnish composition is widely used for painting elements of heating systems, since the dried layer makes the surface perfectly smooth and even, even outwardly resembling plastic. Acrylic paints are practically odorless, both during the painting process and during the operation of the heating system.

When purchasing acrylic paint, you must first study the packaging, paying attention to the manufacturer and the purpose of the composition. Particular attention is paid to the temperature that the paint can withstand, since not all acrylic coatings are designed even for 80 ºС, not to mention higher values.

Acrylic paints dry quickly - the time for their setting and complete drying is indicated in the instructions for use, and can be from ten minutes to an hour and a half for the first stage, and five hours until one layer is completely ready. In order for the coating to turn out to be of high quality, it is necessary to protect the painted batteries from moisture on them during the entire drying period.

Acrylic solutions of paints have a consistency of medium density of sour cream, they do not spread, and practically do not leave smudges. The paint must be applied to the cleaned primed surface in two layers, otherwise the desired effect will not work. A significant disadvantage of acrylic compositions can be considered their low resistance to external mechanical influences, including abrasive loading.

Silicone paints for metal

High-quality silicone compounds have the ability to maintain their characteristics even when heated to critically high temperatures, so the paint based on it will withstand any heat that can be in the heating system. Paints are made on the basis of silicone resin, which is kneaded with organic or aqueous solvents. After the applied layer dries, it acquires a semi-matt sheen.

The silicone compound can be applied to an unprepared metal surface. It is resistant to mechanical stress, to abrasion load, and therefore is very durable.

The only significant drawback of this radiator paint option is its high price, so it is not as popular among consumers as compared to other formulations.

Powder paints

This type of paint consists of a special pigment powder and special binding additives. It can be called the most durable and durable coating for heating radiators, but it will not work to apply it in an apartment.

An obstacle to self-painting with a powder composition is the technology itself, that is, the creation of the necessary conditions for this process:

• Firstly, you need special equipment with which the paint will be sprayed onto the surface of the radiator, but it is very expensive.
• Secondly, a source of precisely calibrated constant voltage is needed to apply the composition - the powder is given a positive charge, and the surface to be coated is negatively charged.
• Thirdly, painting should be carried out in a special chamber, where, after applying the composition, certain temperature conditions are created. To ensure the process of polymerization of the applied powder dye, the surface of the radiator must be heated to a temperature of +170 to 350 degrees (the specific value depends on the characteristics of the composition).

It is clear that it is absolutely impossible to achieve such conditions at home, therefore this type of coloring is most often produced under production conditions. If you want to paint your radiators with a powder composition, you can find a car repair shop that specializes in bodywork, and which is equipped with a set of equipment for painting cars using this technology.

Matte and glossy paint

Heat-resistant paint, like any other, is also divided into glossy and matte. Which one to choose - it will directly depend on the quality of the surface of the radiators.

So, for example, for old-style cast-iron batteries (such as MS-140) with rough outer walls, it is best to use glossy paints - their gloss will slightly hide surface irregularities. In addition, the glossy layer is easier to clean from the contaminants formed on them and remains in its original clean form longer.

Matte paint, on the contrary, will emphasize the flaws in the surface of the radiator. In addition, it will not hide the porosity of the surface, which for this reason will be more susceptible to contamination. Therefore, if white matte paint is chosen for cast-iron batteries, then it will quickly acquire a gray tint. It is problematic to wash the matte surface, and it will be possible to get rid of the unpleasant gray color only with a new stain.

For perfectly smooth surfaces of modern heating radiators, any option is acceptable in terms of the degree of gloss of the paint.

One more nuance. Sometimes manufacturers add fine chalk to the paint to achieve a dull effect. However, what is good for walls and ceilings is absolutely unacceptable for the metal surfaces of radiators. If this ingredient is indicated in the component composition of the paint, then it is better to refuse such an acquisition, since the painted surface of the battery will turn yellow over time, and quickly enough. The best option for a matte paint would be a composition that includes titanium dioxide in its composition, since it will not change its original color throughout the entire period of operation.

A brief overview of popular compositions for painting radiators

Of course, any homeowner, when starting a repair, wants to do it once and for all, so as not to return to the problem of painting radiators in a year or two. This means that it would be advisable to purchase a high-quality specialized composition, even if its price will be slightly higher than conventional paint.

The table below presents some of the well-known brands of the most commonly used alkyd and acrylic based paints, with a brief description of their characteristic features. Perhaps this information will help determine the choice of the optimal material.

In the assortment of stores you can find products from well-known manufacturers, and it is best to choose it, as such materials have passed the test of time and have earned their popularity due to their impeccable quality and durability. Of course, branded products have a higher price, but it is better to pay once and forget about repair work for several years than to spend money, time and effort on painting appliances and heating system circuits every year.

How much paint does it take to paint a radiator?

Paint manufacturers always indicate its average consumption. It would seem that everything is simple. But this is if you paint, for example, the front surface of a panel heating radiator: it will not be difficult to determine the required area there. Another thing is if you have to paint sectional cast-iron "accordions".

The technical characteristics of heating radiators often indicate their total area - if desired, this parameter can also be found on the Internet. But in order not to force the reader to waste time on this, a special calculator has been compiled that will help to carry out calculations very quickly and accurately.

• The calculator takes into account the parameters of the most common cast-iron radiators of the MS and FM series of various modifications. In addition, it is possible to simultaneously take into account the additional consumption of material, if it is also planned to paint the supply and return pipes suitable for the radiator.
• Paint costs for the calculation are taken averaged, by type - oil, alkyd PF, acrylic and silicone. Despite some differences between different brands of coatings, the approximate consumption is still at about the same level. This takes into account the condition that the staining is done in white.
• Different manufacturers do not have unity in measuring consumption - volumetric values ​​\u200b\u200bare indicated in ml / m² (or vice versa, m² / l), or by weight (kg / m²). It is still more objective to judge by the weight equivalent (as is customary in construction planning), since the volume of any paint can be increased by adding a solvent, but its hiding power will not increase from this - it depends precisely on the mass of the material. Therefore, for a unified approach, the final value will be given exactly in kilograms - on the factory packaging of paints, in addition to volume, the net weight of the packaged paint must also be indicated.

The choice of paintwork for the heating system is a rather relevant and undoubtedly important issue. The paint must meet the objectives: withstand high temperatures, maintain gloss for a long time and not snap off. But this is its functional and aesthetic load. But the question of what kind of odorless paint for radiators and how to paint them sometimes remains open. An informative excursion into the world of paints and varnishes will help to understand.

Which one is better to choose

The choice of paint for the heating system of an apartment or house is closely related to the material from which the batteries are made. Each of its types has certain properties that are friendly to the paintwork or conflict with it. The main types of materials used for the production of radiators:

• cast iron;
• bimetal;
• steel;
• aluminum.

For painting heating radiators, the market of manufacturers offers a wide range of species and a rich palette of coatings:

№	Varieties of coatings	Kinds painted radiators	Advantages	Flaws	Firm- manufacturer
1	Oil paint	Cast iron	Wide color palette	Dries for a long time, has a persistent smell, quickly fades, cracks, loses shine	"Tikkurila", etc.
2	Serebryanka	Cast iron	Excellent high temperature resistance	Persistent odor	"Lacra", "Gloss", etc.
3	silicate paint	Cast iron	Designed for high temperatures	Long lasting odor	"Nevbytkhim", "Ceresit", etc.
4	Powder paint	Any kind	Durability, resistance to damage and high temperatures	Coloring in professional cameras	"Triton", "Ral", etc.
5	Alkyd enamel based on organic solvents	Cast iron, steel, bimetal	Rich range of applications	Characteristic smell, color varies by pigment	"Olecolor", "Enamel", "Tex", etc.
6	Water based alkyd enamel	Any kind	Barely pronounced odor, no color loss	Titanium white is added to the high-temperature paints of this series, which are not cheap.	"Tex", "Lacra", "Enamel", etc.
7	Alkyd hammer enamel	Cast iron, steel, bimetal	Hides paint imperfections	There is a faint smell, which disappears after drying	"Olecolor", "Tex", "Enamel", etc.
8	acrylic enamel	Cast iron, steel, bimetal	Almost no smell, dries quickly, wide range of colors, durability	It is required to carefully prepare the surface to be painted: sand, prime	"Lacra", "Rainbow", "Tex", etc.
9	Paint in cans	Any kind	Wide range of colors, ease of dyeing process	Strong smell	"Kudo", "Decorix", "Newton", etc.

Can it be hot dyed?

The opinions of experts on the issue of painting radiators differ: some argue that they need to be painted to protect them from corrosion. Others retort that the application of one or another type of enamel on radiators does not perform any protective function and is purely aesthetic in nature. Another thing is painting pipes in winter when the radiators are hot.

Paints and varnishes suitable for the heating system and withstanding high temperatures require painting on cold batteries. If the radiators are covered with enamel on a hot surface, then the paint will dry “on the fly” and the quality of the coloring will get out of control: sagging and unsightly spots will appear.

It will not be superfluous to recall that when coated on a hot radiator, the smell of the paint will intensify, and opening windows in winter for ventilation is problematic due to the cold.

Important! Consumers most often choose the white color of the battery coating, but experts say that the dark tone of the radiator color contributes to better heat dissipation.

The painting process

Before proceeding to the stage of applying paint, you need to stock up on the necessary equipment:

• radiator brush (curved, with a long handle);
• regular brush (100 mm wide);
• rubber or silicone gloves;
• respirator (if paintwork is odorous);
• newspaper (to protect the floor from paint stains);
• sanding sheet No. 2 (if necessary, cleaning the batteries from irregularities);
• rag;
• primer;
• dye;
• white spirit (for unexpected skin contact with paint).

Sometimes, the preparatory work takes more time than the staining process itself. This is not surprising, because the radiator has a lot of hard-to-reach parts that need to be washed, and in some places peeled off paint and sanded.

Important! If there is a desire to remove the old coating completely, then you can use a special wash.

1. Prime the prepared surface.
2. In order to avoid drips, painting starts from the top of the heating system.
3. The internal parts of the batteries are also coated first.
4. Layers of paint are applied evenly in a thin layer.
5. As the paintwork material dries, the radiators are repainted.

Technology of painting on old paint

The condition of the paint on the heating system can be different:

1. The coating, although old, faded, but has a monolithic adhesion to the base. It is enough to sand the surface a little with sandpaper for reliable adhesion of the next layer of paint.
2. The old coating is worn in places, peeled off and metal is visible in places. Here, a more thorough grinding of the surface will be required so that chips and irregularities do not show under the new layer.
3. The paintwork is hardened, flaky in large areas, rust shows through in places. Such paint must be mercilessly removed with a metal brush or special preparations for washing. The prepared surface is primed before applying the first layer of paintwork materials.

Important! You can simply update the old paint: apply a fancy pattern to it, after sanding, for better adhesion.

in cans

For the convenience of consumers, paint and varnish manufacturers produce an aerosol coating for radiators. It has excellent properties:

• withstands high temperatures;
• easy and quick to apply;
• dries almost instantly;
• has a pronounced gloss;
• adheres well to any surface.

The only downside is the strong smell., but it will fade in just an hour.

Balloon paint is sprayed onto the surface to be painted from a distance of 30 cm. The movements should be smooth, but fast, in a zigzag pattern. Depending on the quality of the surface of the heating battery, it may be necessary to paint in several layers.

Important! When working with aerosol enamel, it is necessary to cover a large area around the radiator with newspapers, because. skill in painting with spray paint will not come immediately.

Having the necessary information about the coatings of radiators, you can get useful tips and learn about the features of the technologies for using paint and varnish products.

To begin with, it is necessary to paint the batteries when the battery is disconnected from the heating system. In theory, it is possible to paint a hot battery, but this is unpleasant and when painting a hot pipe, there is a possibility that the paint will be applied unevenly. Now let's move on to the main thing, is it possible to paint hot batteries?

The main task is to evenly paint the battery. To do this, use brushes or a paint sprayer. Paintbrush - allows you to apply a more subtle color. It is recommended to paint the lower part of the battery with a brush. Painting should start from the top. After the first coat of paint has dried, apply the final coat. Done.

How can you paint a hot battery?
For battery painting, the following paints are used: alkyd enamel, water-dispersion acrylic paint or polyacrylic enamels on organic solvents. It must be ensured that the paint is resistant to elevated temperatures, i.e. the paint must not crack due to the rise in temperature.

Alkyd enamels
Alkyd enamel has a uniform coating structure, resistance to elevated temperatures and strength. But, alkyd enamel has a very disgusting smell. This is his only drawback.
Water-dispersion paints
Such paints are best suited for painting batteries, you just need to choose a special type of paint. After painting, harmful substances are not emitted, moreover, the paint dries quickly.

Acrylic enamels on organic solvents
The coating has a glossy sheen, does not change its color over time. However, during operation, an unpleasant odor is emitted.

Battery preparation before painting
Before painting the battery, you need to make sure that the steel surface of the heating radiator is perfectly clean. All this is done to ensure that the new paint is extremely firmly in contact with the surface of the battery, providing better heat dissipation. An unfinished surface will lead to undesirable consequences: paint cracking, damage to the coating layer, etc.

Most often, an old layer of paint remains on old radiators. Such batteries can be used, but only if the battery is not damaged and its surface is free of old paint and rust. To remove the old layer of paint, you need to use sandpaper or special solvents. In order to speed up the cleaning process, you can use a building hair dryer.

By the way, only after we have finished cleaning the surface of the battery, you can start painting.

Of course, buying new radiators is a very expensive pleasure. And what about the owners of old, Soviet cast-iron batteries? of course, paint them. Thus, you can create your own individual interior. Painting is best done in the summer, when the heater is cold and the smell from the paint will quickly disappear.

So is it still possible to paint hot batteries? Of course you can, you just need to choose the right paint. Once again, read the label on the jar carefully.

So get down to business boldly. We hope that our advice will help you in ennobling radiators in an apartment or house.

What to do if there is an urgent need to repaint hot batteries? This can be done, but the quality of work will be poor and it will be troublesome.

In order for the work to be done as it should, and in the future there would be no problems, we advise you to take into account some of the nuances:

There are two ways of processing heating devices: a mechanical method and a chemical one.

1. The chemical method of processing consists in the use of special chemicals that are able to dissolve the old layer of paint and remove it without much difficulty. Do not forget about security measures. When working with chemicals, you must wear gloves and goggles.
2. The mechanical method or “manually” is based on the use of sandpaper, scrapers, drills with special nozzles.

So is it still possible to paint hot batteries? Of course you can, you just need to choose the right paint. Once again, read the label on the jar carefully.

High-quality paint for painting batteries will cost about three hundred rubles. A good hardware store can tint you if you wish. Usually they charge fifty rubles for this.

So get down to business boldly. We hope that our advice will help you in ennobling radiators in an apartment or house.

Odorless paint for radiators

Paint for painting radiators must withstand high temperatures, i.e. be heat resistant. It is also good if it meets the requirements of environmental friendliness, i.e. does not emit harmful and unpleasantly smelling substances when heated.

Paint role:

• Making it aesthetically pleasing
• Corrosion protection
• Protection against aggressive environmental influences

How to remove old paint from a radiator

Before applying new paint, the surface must be prepared. To begin with, coarse dust is removed with a vacuum cleaner, fine dust can be wiped with a damp cloth. Grease stains are easily amenable to solvents and dishwashing detergents.

If the old coating is well preserved, does not flake off, does not swell, rust spots do not appear through it, then for simplicity and saving time, you can simply go over it with sandpaper so that the new layer of paint adheres well to the old one.

If the old paint has a completely unpresentable appearance, then you will have to get rid of it.

You can remove the coating from the battery as follows:

• Drill with a nozzle in the form of a hard brush - ruff
• Solvents - flushes
• Sandpaper.

Mechanical means of removing the old coating guarantee a large amount of dust, and if used carelessly, they can damage the battery itself.

Nozzles for removing paint

Chemicals are safer in this regard, but you should work with them in a ventilated area and use protective equipment - gloves, a respirator, goggles, etc. Also, do not smoke or make fire, because solvents are flammable.

As a rule, solvents are available in the form of a thick liquid or gel. They are applied in an even and not too thin layer evenly over the entire surface of the battery. For application, metal or wooden spatulas or brushes with natural bristles are used. Spatulas made of rubber or plastic will simply dissolve from aggressive chemical exposure.

The gel is kept on the surface for the time specified in the instructions, after which it is cleaned off with the same spatula along with pieces of softened paint.

Solvent residues are washed off with water.

Rust can also be removed by mechanical sanding or corrosion inhibitors. Large dents or chips should be sealed with putty.

After that, dust and dirt from the old paint should be removed, allow the battery to dry. Next, a primer suitable for the given type of radiator metal and the selected paint is applied. It contains small sandy particles, the role of which is to increase the adhesion (adhesion) of the surface with the paint.

There are also paints that already contain substances similar to the primer, which perfectly protect the battery metal from corrosion and adhere well to the surface.

Coloring process

It is better to paint batteries outside the heating season, then the paint will dry evenly, there will be no smudges, cracks, swelling, etc. If this is not possible, then the thinnest possible layer should be applied. Ideally, if the battery is not yet installed, or it is possible to remove it to paint over everywhere.

Important! All water-based paints must be applied over a primer. When applied directly to the metal of the battery, you will have to deal with the rapid appearance of rust through the paint.

To keep the floor clean, use unnecessary cloth or newspapers under the radiator. If the dye is applied from a spray can, you will also have to cover the adjacent surface of the walls with something.

Battery painting with a brush

For work, it is better to choose brushes with soft bristles, less splashes will scatter from them. An ordinary old toothbrush will help you get to the most inaccessible places. In order not to get dirty on an already painted surface, it is better to first paint over the internal parts of the radiator. Paint should be applied from the top of the radiator down.

Do not try to immediately evenly paint the battery in one layer, it is still unlikely to succeed. Two neat thin layers will be better, because one thick one will dry much longer, it may leak. The time for which the dye layer is completely dry is usually indicated on the packaging. It is not worth applying the second layer ahead of time, the coating will turn out to be uneven, sloppy.

Coloring can be done not only manually, but also with a spray gun or from a spray can.

Paint for batteries in a can

Paint selection

Although conventional paints intended for walls, floors and ceilings are used for heating batteries, this is not the best solution. They are not designed for temperature effects, and therefore they will crack much faster and acquire a yellowish tint.

Heat resistant paint for radiators

When choosing between matte and glossy paints, it should be borne in mind that a shiny coating will strongly attract the eye and emphasize all the imperfections and surface irregularities. A light matte finish will turn gray over time, because dirt will accumulate in the porous structure of the paint.

Although the usual color of the batteries is still white, this is more of a tribute to the Soviet past, when the choice of colors was not rich. In fact, white radiators will only look good in light-colored interiors. For bright or dark rooms, you should choose a different color for painting.

Interesting! The battery can be turned into a noticeable and attention-grabbing interior detail if you paint it in bright colors, draw patterns or whole pictures.

Painting aluminum radiators

Aluminum batteries themselves have a neat looking and even finish and do not need additional painting.

Is it possible to paint hot batteries

If the convection plates of the radiator are located very often, then their coloring will significantly reduce the heat transfer of the device.

If their appearance hurts the eye, then it is better to close them with a screen or make them furniture. If these options are not suitable for some reason, then the radiators can, of course, be painted. But paints suitable for cast-iron batteries will not adhere well to an aluminum surface. Such radiators should only be spray-painted. Moreover, this should be done during the heating season, because on cold batteries at room temperature the paint will dry for a very long time.

Important! It should be noted that most manufacturers of aluminum radiators consider their unauthorized painting to be sufficient reason to terminate the warranty service.

Types of paints

Alkyd

Alkyd paint for a heating battery is organic, silicon-organic or water-based. In the first few hours after application, it has a strong smell, which then disappears completely. With the beginning of the heating season and the heating of appliances, the smell may return for a short time.

If white paint is chosen, then it is best to purchase one that contains titanium pigment. Options with a chalk content, although they will cost significantly less, will quickly turn yellow during operation.

Acrylic

Acrylic paints for radiators look and feel strongly reminiscent of plastic. This cover stays on well and is easy to clean. If the acrylic dye has a water base, it will be completely devoid of an unpleasant odor.

Hammer

Hammer enamels allow you to get shades of the same color and different textures. A non-uniform coating will perfectly hide irregularities and other surface imperfections.

Preparation for application and the coloring itself will not differ from the usual. The only thing that is required is to sand the radiator to create a rough surface.

Water emulsion

Many people wonder if it is possible to paint batteries with water-based paint. Of course, you can, because. it combines resistance to high temperatures, fast drying and the absence of an unpleasant odor. However, it is significantly inferior in durability to other species.

Powder

Gaining popularity so-called. powder coating. The dry mixture is applied from a special gun due to a small difference in electrical potentials between the radiator and the powder itself. After application, such paint must be polymerized. Indoors, this can be done with a heat gun, and if the radiator is removed from the wall, it can be placed in the oven. There are also options for powder dye that hardens when exposed to ultraviolet light. However, ordinary sunlight is not enough for this, it is necessary to use an ultraviolet lamp.

silicate

Paint for batteries based on silicate resins and aluminum is designed to work even with very high temperatures, which in practice do not happen in a heating system. After solidification, the material forms a dense, durable, but plastic layer, due to which no cracks will occur during thermal expansion and contraction of the metal. Such paint does not require preliminary application of a primer and has very high adhesion to the surface. Among the disadvantages of this option are only a high price and a strong odor that takes a long time to fade.

Serebryanka

It has long been used for painting radiators and silver - a mixture of varnish with aluminum powder. Such paint perfectly withstands high temperatures. It should be applied either over the layer of the old coating or on the base in the form of a primer. Since silverware contains oil products among the components of the varnish, it has a fairly persistent strong odor, i.e. the room must be thoroughly ventilated.

Advice! Car enamels in spray cans are very well suited for painting heaters, because. they are also designed for strong heating during operation and application to metal surfaces.

Conclusion

What paint to paint the radiators is ultimately up to the buyer. It is only necessary to carefully weigh all the advantages and disadvantages of each of the possible options. For a room in which people are currently living, quick-drying, odorless radiator paint is better.

In a not yet residential area, paints that dry for a long time, but have a longer life of further paint service, are also suitable. You should not save on the material, it is better to give preference to proven and well-known brands. To check how much in reality the indicators of a particular paint correspond to the declared ones, and decide which battery paint is better, user reviews that can be easily found on the Internet will help.

Radiators installed in the heat supply systems of private households, apartments or other real estate objects need to be painted periodically. How to paint heating batteries with your own hands and how?

The need to paint heating equipment

Heating appliances need to be painted in only two cases:

• if on operated cast-iron batteries the old paint has lost its original color and peeled off;
• if the builders installed convectors of the 90s of the last century in the house, which are a coil of a heating riser with a few pressed-on finning plates.

If painting is required in the second case, then only the decorative screen and the damper swinging from above are subjected to it. There is only one way to paint the inside of the battery with fins between the plates - this is by completely immersing the convector in a container with a coloring composition. But the narrowing of the gap between them leads to a decrease in the heat transfer of the equipment.

Heating devices of a more modern type should not be painted, especially for products with aluminum fins. If this is done, then the heat transfer of such a radiator will decrease and its appearance will deteriorate. The fact is that layers of paint smeared with a brush are unlikely to turn out to be perfectly even and the result will not look like a resistant powder composition applied in the factory.

Lamellar radiators and other heaters, which have a large frontal area, made in the form of a single panel, it is desirable to paint on the floor in a horizontal position using a can or spray. As a result of using this method, the paint layer is almost perfect.

However, regardless of the choice of how to paint the batteries beautifully, the product will not get better. To fit them into the color scheme of the renovated premises, you can use a decorative screen for heating radiators.

The choice of coloring composition

Deciding how to paint heating equipment depends on the personal preferences of property owners. When you need to choose an odorless composition, then it should be water-soluble.

How to choose paint and paint radiators

All paints produced on the basis of synthetic varnishes smell during the drying process.

Of the commercially available water-based compositions, two types of paints differ in abrasion resistance:

Coloring compositions that are applied at room temperature on a cold surface of the product will dry for 4 to 8 hours. But they will not be completely resistant to abrasion - as a result, traces will appear on clothes and curtains.

How and how to paint a cast-iron battery at home, if long and trouble-free operation is required? Of the paints intended for use in everyday life, according to experts, the best option is the use of domestic alkyd enamels PF-115 or their imported counterparts.
These paints are resistant to temperature changes, they are intended for use inside and outside of real estate. The price of a can weighing 2.6 kilograms is affordable for most consumers.

Another viable option is to use car enamels. But their application requires an ideal surface, otherwise all the irregularities will become clearly visible. Auto enamels are applied from a can and therefore, if the radiator cannot be removed, then a hardboard or cardboard screen is installed between it and the wall.

A simple option for painting radiators

The instruction on how to quickly paint the batteries and bring them back to normal depends on the time during which this work must be done.

You can use a simple method in which:

1. The surface of the device is prepared in two stages. First, the layers of the coloring composition are heated with a gas burner or a building hair dryer, and then they are removed with a hard spatula and the surface is protected with a metal brush. By the way, sanding the battery for painting with sandpaper is very, very tiring and takes a lot of time.
2. Remove rust and dust with a damp cloth.
3. Then the paint, diluted to the state of fatty milk, is applied in two layers with drying of each of them for at least a day.

When painting, you must adhere to several rules:

1. It is not necessary to try to paint the device at one time when the paint layer is visible. It is better to spend 24 hours drying and then apply the next layer, otherwise the color will turn out to be uneven, sagging will appear. But, if this happens, it is possible to eliminate the shortcomings, for which the surface area must be cleaned again and another thin layer applied on top.
2. When you want to paint hot batteries, you should pick up quite a bit of paint on the brush at a time, quickly grind it with the thinnest possible layer in a well-ventilated area.

Subject to the above rules, poisoning with a rapidly evaporating paint thinner is excluded and untidy sagging will not appear on the radiator, since the coloring composition dries quickly on a hot surface.

The right way to paint heaters

There is a way to paint cast iron batteries, returning them to their original appearance, removing streaks between sections and the shortcomings of the previous painting. The work is carried out, as in the previous case - with a brush, applying two thin layers.

The preparation of the radiator is performed differently:

1. The risers are dropped, the device is removed and the remaining coolant is drained from it.
2. Unscrew all deaf and through plugs. Remove washers.
3. The radiator is annealed for at least one hour on a fire in the yard. Carrying out annealing with a blowtorch or a hairdryer is a tedious and inefficient task.
4. The cooled battery is disassembled into sections using a radiator key, after annealing it will be easy to do.
5. Each section is tapped with a mallet. Rust accumulated over many years will fall out of it, and as a result, the channels inside will be cleaned.
6. Sections are cleaned with a metal brush. After annealing, the procedure will be easy and fast.
7. The radiator is reassembled using rubber gaskets. They can be made from an old car chamber a little smaller than the end of the section. In this case, the squeezed gasket will not protrude beyond the edges.
8. Next, the battery is mounted, pressure tested by simply filling the riser and painted.

Of no small importance for the appearance is the decision what color to paint the battery. The classic version is white or silver. But if desired, the color can be gray-green, brown or any other. As for heat dissipation, batteries of dark shades do it best.
