If guided technological maps on Finishing work(documents that indicate the sequence of actions), then you can observe the following: any finishing paint coating is applied to the prepared and putty surface. But there are controversial issues, for example, is it possible to glue wallpaper over paint? - yes, this can be done under certain conditions.

The previous coating must be firmly adhered to the plaster layer, and also cleaned of dust, various contaminants and other defects. Accordingly, the first stage is an inspection of the surfaces. It is enough to run your hand over a layer of old paint, and it will immediately become clear where it lags behind and where it holds tightly, then carefully clean these places with a spatula or scraper.

There are many paint compositions, but is it possible to glue wallpaper on water-based paint? - yes, this is possible provided that it holds tightly. But there is a nuance: when applied adhesive composition onto such a surface, it sets with lightning speed, so it is worth pre-treating it with an acrylic dispersion primer, which will remove excess water absorption. During priming, it may swell in places of poor adhesion - that's okay, you just need to take a spatula and clean them out.

As for other surfaces that are based on oil paint, then yes, it is also possible. However, you will have to resort to continuous mechanical treatment, in addition to identifying and eliminating crumbling areas. The fact is that oil compositions form a waterproof coating on the surface that is not capable of absorbing the adhesive composition. To ensure adhesion, the entire surface is roughened sandpaper, thus there are many minor scratches- pores into which glue flows.

You can add 10% PVA glue to the adhesive starch composition, this will improve the tenacity, but for this case it is best to buy ready-made polymer glue, which can also be used to glue wallpaper onto enamel paint after the above-described treatment. Sometimes you can observe a sandless coating being carried out over an oil or enamel surface, after which a new topcoat is produced.

It is highly undesirable, but you can still glue wallpaper onto paint on water based. Such paints include old casein glue rolls, as well as whitewash. In the first option, the surface must be checked as always, then carefully primed. If the surface is whitewashed, then it will be impossible to paste wallpaper on it; you will have to carefully wash it down to the base (a primer will not help).

There are no special nuances about how to glue wallpaper onto paint; it is important to level the vertical marking lines of the first canvas on each wall, taking into account uneven corners. As always when performing wallpaper work, drafts must not be allowed within 24 hours from the moment of pasting; If the surface was painted with oil paint or enamel, the drying time of the glue may increase by 2-3 times.

Wallpaper is very difficult to adhere to on a curved surface (oil or enamel), the seams may lag and come apart, and to avoid this, you need to pull the sandpaper. In addition, if the wallpaper is to be painted, then everything is even worse: it can peel off in places and the joints may separate during the painting itself.

You can also watch a video on how to glue wallpaper onto paint, but according to technology, such techniques are not performed.

Very often there are walls painted with oil paints. This coating is particularly durable, but, nevertheless, the time comes to replace it. In such situations, the question arises: “Is it possible to glue wallpaper on oil paint?».

What should you do, start the long, rather dirty and unpleasant process of removing paint, or can you simply cover the unpresentable surface with wallpaper?

Determining the type of coating

When the time comes for repairs, it is necessary to clearly determine the type of surface. Everyone is used to calling any type of paint that cannot be washed off with water oil, although this is incorrect.

Important! There is no ban on wallpapering with oil-based paint, but it is still recommended to clean the base from it.

Old coating

So, before you hang wallpaper, you need to carefully examine the walls:

Preparing the walls

If you decide to leave the paint and glue wallpaper on it, then the first thing we recommend doing is sanding, i.e. make the coating rough, since oil paint is smooth and does not adhere to anything.

Before gluing the canvases, you need to decide on the choice of glue. At the same time, pay attention to the advice of experts, and they, all as one, say that it is better to take glue only for heavy wallpaper, even if you are going to glue light single-layer wallpaper.

Advice! If it allows financial position, purchase PVA glue, it can be used both independently and together with wallpaper glue in proportion 1 to 1.

Primer

So, all further actions before gluing the wallpaper should increase adhesion; accordingly, it is necessary to completely overcome the property of oil paint to repel substances rather than absorb them.

Experienced builders who know how to hang wallpaper so that it for a long time served faithfully, they advise you to do the following:

• First, we purchase a primer with high penetrating ability. “Concrete Contact” works well;
• Next you need to wash the walls and then let them dry completely;
• Apply the primer solution to the oil paint with a layer of 0.75 mm, and also let it dry completely;
• then putty, then after drying, apply another layer of primer;
• Only after this can you glue the wallpaper.

Advice! You can prepare the primer yourself, using PVA glue and alabaster.

Cooking steps:

How to glue

Most have their way personal experience already know how to properly glue paper wallpaper, and this is done as follows:

But we should not forget that the surface on which you plan to paste the wallpaper is in this case, not standard, so some other factors are taken into account:

• It is necessary to pre-apply glue not only to the wallpaper, but also to the wall, this helps to strengthen adhesion and, accordingly, will reduce the risk of the wallpaper coming off;
• The presence of a draft is unacceptable, both during work and after its completion. Openings, doors and windows, must be closed until completely dry;
• In no case should you work in high humidity, too high or, conversely, too low temperatures.

How to apply wallpaper to paint is shown in the following video:

Results

To summarize, it can be noted that professionals do not recommend gluing wallpaper over any paint, but there are no clear prohibitions against this. If such a decision is nevertheless made, it is necessary to take the work very seriously and not allow the slightest mistake.

But it should be noted that even if you do everything strictly according to the instructions, there is no 100% guarantee that you will be able to hang the wallpaper successfully, you will get an ideal surface and the wallpaper will serve you long period time. As for the rest, it’s up to everyone to decide individually: is it worth the risk, or spend a little more effort and time and completely clean the surface of the old paint?

are wallpaper.

True, before you start gluing them, you need to prepare the surface.

Often the walls you intend to cover are covered with paint.

In this case, a reasonable question arises: how to apply wallpaper to paint and is it even possible to do this? There is a way out, we will figure it out.

So, if you are planning to do renovations in the apartment yourself, first study carefully.

An inexperienced painter will classify any durable paint as oil paint.

Although this is a rather contradictory fact for an exact definition.

There are several valid arguments:

• A surface that lacks shine and cannot be wiped off with a wet cloth most likely indicates that the walls are painted with water-dispersion paint. You won’t be able to touch it with water, but you can easily remove it with a spatula.
• But whitewash is very easy to recognize: run your hand along the wall, white marks will remain on your fingers. If you paste wallpaper onto such a surface, the next morning you will be greeted with an unpleasant surprise in the form of strips of paper lying on the floor. If there is whitewashing, preliminary work is necessary: ​​with a brush or sponge dipped in water, you can wipe off the “dangerous” coating for the wallpaper.
• Oil and enamel paints make the surface shiny and smooth, but they do not react at all to water. Most often, these types of coatings were used to forget about repeated repairs for a long time.

Please note: although the instructions say that it is not recommended to glue wallpaper to the latter type of paint, there is still no strict prohibition and technologies for preparing such walls are known. So nothing is impossible. The main thing is to stock up on instructions on how to hang wallpaper on an oil floor.

We glue wallpaper with oil paint

An important stage is preparation.

In the first and main stage Preparing the premises includes several important points:

• Carefully and thoroughly inspect all walls for cracks, broken pieces of plaster or putty.
• Remove all nails or other protruding elements, remove the baseboards.
• If more than half of the old coating has been removed, it should be removed entirely.

Sanding process

If the walls are acceptable for pasting even without the mentioned preparatory materials, there are still some techniques that cannot be avoided. One of these is sanding.

Why is this process necessary? The thing is that oil paint has the property of poor adhesion.

You can increase adhesion by simply turning smooth surface into a rough one. That is, perform a few simple manipulations:

• Prepare sandpaper with large grains.
• Rub it all over the walls without exception.
• Apply primer to the treated surfaces.
• Dry it overnight.
• Putty the walls with a gypsum-based mixture, thereby making them even and smooth.
• Wet the surfaces with warm soapy water. It will remove all unnecessary fats and the paper will stick to the walls without any problems.

For better adhesion, you can use another trick - add PVA to the wallpaper glue in a ratio of 1/1. There is another way: polyvinyl acetate, diluted with a small amount of water, is applied in a thin layer to the wall and, without waiting for it to dry completely, they begin to glue the wallpaper.

Glue matters

The right choice plays an important role in performing home renovations.

If you don't feel confident in accepting independent decision, seek help from a specialist in any hardware store There is a consultant who can easily answer all your questions.

Ask him to show him glue for heavy ones, and even if the material prepared for gluing is thin, purchase a mixture for vinyl paper covering.

The following types of glue are best suited:

• "Moment"
• "Methylane"
• Bustilat

If price is not of fundamental importance, you can also buy PVA. Its influence on the quality of adhesion to oil-based paint has already been discussed above.

Surface priming

All procedures that should be carried out with the surface at the preparation stage are aimed at improving the adhesion of oil-painted surfaces to paper finishes.

The following process serves the same purpose. Priming the walls will increase the ability to absorb substances. And the risk of wallpaper falling from the walls will be minimized by doing the following:

• Purchase soil from a specialized store.
• Wash the walls.
• Leave them until completely dry.
• Then apply a 3-4 mm layer of primer.
• Dry the applied layer.
• Putty the surface.
• Apply a coat of primer again.
• Wait until the walls are completely dry.
• Finish the prepared surface with wallpaper.

Please note: you can prepare the primer yourself. This option will be even more economical. You only need two ingredients:

• Alabaster

The cooking process consists of several simple steps:

• Pour 300 grams of water into a deep container.
• Add alabaster into it, stirring constantly. The consistency of this composition should resemble sour cream.
• Add PVA to the resulting mixture in a ratio of 1/3.

Lubricate the pre-washed walls with the prepared solution and leave until completely dry.

You won’t have to talk long about how to apply wallpaper to enamel, since in the case of such an old coating, you will need to follow all the procedures described above. These two paints have few differences, therefore the methods of exposure are identical.

Whitewashed wallpaper? Let's glue it!

A few high-quality manipulations with a surface treated with oil paint or enamel, and you can safely glue wallpaper. Concerning water-based coating, then it’s even easier with it - wash it off warm water.

But with whitewashing the situation is much more complicated. Remember, if you decide to glue wallpaper on whitewashed walls, you will have to completely remove the old coating, since it cannot withstand the load at all. None!

The step-by-step procedure for cleaning walls can be presented as follows:

• Soak the whitewash with warm soapy water.
• Remove with a spatula.
• Wash off the residue with a sponge.

Important: whitewash should be removed completely and in all areas where wallpaper will subsequently be painted.

Checking the quality of the product is not difficult: just run your hand along the wall. Chalk remaining on the palm is an indication that not all of the coating has been removed and will have to be washed again.

Please note: checking is very important, otherwise the canvas will come off exactly in those places where the paint remains, and in case of high humidity, bubbles may also appear.

The second method of preparing whitewashed walls is also known; it involves the following manipulations:

• Treat the surface with a primer.
• Dry thoroughly.
• Apply a coat of primer a second time.
• Dry again.
• Dissolve the glue.
• Dilute it with water.
• Apply the prepared mixture to the walls.
• Let dry thoroughly.
• Glue wallpaper.

How to paste wallpaper on whitewash is presented in the video:

Pasting concrete walls

The bases that were discussed are traditional, but what to do if the base for wallpapering is a concrete wall? What to do in such a situation?

Carrying out preparatory measures, as in the case of oil paint, enamel and whitewash, will be unnecessary; there is no old coating and, accordingly, there is no need to get rid of it.

True, there is a subtlety that should not be forgotten: concrete walls covered with tubercles and pits, and expensive wallpaper coverings “don’t like this” and require evenness.

But in order to make it so, it is still worth carrying out a set of measures:

• Smooth out unevenness.
• Remove dirt and dust.
• Clean the base with sandpaper.
• Plaster.
• Prime with a high-quality composition that will protect against the formation of mold and mildew, will be resistant to moisture and will firmly bond the wallpaper to the concrete surface.

Anyone who has ever done home renovations knows how to glue paper sheets to walls. And this technology is general outline looks like that:

• Apply glue to the wallpaper strip.
• Attach it to the wall.
• Align vertically.
• Smooth out wrinkles, bumps and bubbles.

IN currently It cannot be argued that this is the only true one; it should be disseminated with some general advice:

• Apply glue not only to wallpaper, but also to walls. This precaution will enhance the adhesion of the material and the surface. Such measures can be eliminated only when covering the room with non-woven wallpaper.
• Do not open windows and doors during work and until the wallpaper is completely dry. Drafts can play a cruel joke, reduce the possibility of their occurrence to a minimum.
• Heat, like cold, is not best helpers at work. High humidity It should also be avoided in the room where finishing work is being carried out.
• When choosing wallpaper, pay attention to the pattern; it will need to be joined.
• Calculate the number of rolls you need, but still take extra.
• Select glue only in accordance with the purchased wallpaper. And under no circumstances use one that is not suitable for the type you have chosen. It must be diluted strictly following the instructions written on the package.
• Wallpaper must be glued on top and aligned with the ceiling. It is recommended to start pasting from the window opening. It is better to allow canvases not according to precisely measured dimensions, but by leaving a small margin at the top and bottom.
• You can use either a rag or a rag. Prepare an unnecessary rag to remove excess glue.
• It is best to seal switches and sockets first and then cut them. This must be done before the wallpaper has dried, then all the cuts will be smooth and neat.

The glue should only be room temperature and under no circumstances hot.

Otherwise, the front side of the wallpaper can become very dirty.

First we glue the solid strips and only after that above the doorway and under the window.

If you have received a detailed and understandable answer to the question of how to apply wallpaper to paint, you can safely get to work and apply the knowledge you have gained in practice.

High-quality and accurate work will be long years to delight you and your loved ones with its appearance.

The decision to use wallpaper as wall decoration or flow has been considered justified for many years. They resorted to this option many centuries ago, and they still resort to it now, fortunately modern market building materials offers a huge range of them. But there are certain requirements for the gluing process itself. Since wallpaper is glued, it is necessary that the surface on which it is glued has good adhesive characteristics.

Therefore, the question of whether it is possible to glue wallpaper with oil paint is still relevant today. Let's start with the fact that when applied, oil paint is well absorbed into the surface being treated, even if it was applied in several layers. The surface of such a painted surface is glossy, so wallpaper does not stick to it. Experts advise getting rid of surfaces painted with oil paint by any means. Most perfect option- remove it with sandpaper or a special brush attachment, which is placed on the drill chuck. Of course, after such an operation, the wall will have to be leveled and prepared before wallpapering it.

But imagine that you decide to wallpaper a large area. This means that you will have to clean the same area of ​​oil paint. It's long, it's not easy, it's dirty and dusty. Are there other options? There are, and there are two of them. True, even in their case you will have to prepare the surface and then glue wallpaper onto it.

Option number one

This is the simplest option. To do this, use coarse sandpaper to sand the surface of the wall painted with oil paint. After which it is treated with a mixture that includes PVA glue (50%) and primer (50%). The primer is absorbed into the exposed areas of the wall, forming a bond with the mixture. PVA glue clings to painted areas. Wherein thin layer The adhesive composition covers the entire wall, turning its plane into a platform with a good adhesion rate. Dries like this finishing layer at least a day. After which you can begin the main process.

Option number two

This is a more complex technology, because you will have to strictly adhere to a certain distance between the areas that open between the paints. To do this, you will need a spatula, with which you need to remove vertical sections of paint in the form of strips 5-6 cm wide. The distance between the strips can vary in the range of 20-25 cm.

By the way, it is not necessary to remove the paint layer with a spatula. As practice shows, if the paint is attached to the wall tightly and firmly, then it will be very difficult to tear it off without damaging the wall itself. Therefore, you can use a drill with an attachment. A wire brush will only remove a layer of paint and go a little deeper into the body of the wall. After which these strips are filled with putty solution to the level of the plane of the painted surface. And then, as usual: the putty is sanded and treated with a primer. You don’t have to sand it if you are sticking thick wallpaper.

Attention! If non-woven or vinyl wallpaper (thick and dense) is chosen for finishing the walls or ceiling, then there is no need to repair and level the walls. They will cover all minor defects and differences.

Other options

Home craftsmen experiment all the time, finding quite original and simple solutions. Same with how to glue wallpaper on a wall with oil paint. Eg:

The second option is usually used if old paint not in very reliable condition. Weak, unreliable areas will have to be beaten off or removed with a spatula. After that, a material such as “Betokontakt” is applied to the entire surface to be finished. This is essentially a liquid primer that contains quartz sand. After drying, a layer with a high adhesion index will appear on the surface. At the same time, the primer applied to the surface being treated does not absorb moisture from the wall, which allows it to dry evenly without cracking or peeling.

If liquid wallpaper is to be applied to the wall, then the surface must be thoroughly washed or cleaned, and Betokontakt applied (you can use a primer for liquid wallpaper), and only then boldly apply finishing material. Of course, the condition must be met that the paint itself lies securely on the wall surface. In this case, before starting work, it is necessary to remove all nails and screws from the wall, and it is better to paint over the metal embedded parts. The goal is to prevent rust from appearing, which will certainly appear on the surface of the liquid cladding.

How to hang wallpaper over oil paint? This issue is especially important for owners of apartments from an old building, where the walls are often painted with oil or enamel paints. Despite the durable and high-quality coating, renovation of the room becomes inevitable over time, which raises a natural question - is it possible to glue wallpaper onto oil-based paint without removing it to the very base? This article offers the answer to this question.

Features of oil paint

This material is made on the basis of ordinary drying oil, which can be:

1. Natural.
2. Artificial.

First, the pigment that is most present in the color scheme is mixed, and then the rest of the ingredients are added. The paint is diluted to the required thickness.

The advantages of these coatings include:

1. High strength.
2. Durability.

If you want to stick wallpaper onto paint with your own hands, you need to determine its category:

• If the wall surface is not shiny, it cannot be wiped off with a wet cloth, most likely it has been used water-dispersion paint for coating. It will not be possible to soak it, but removing it with a spatula is possible and not too difficult.
• The situation is easier with whitewashing. To determine it, you just need to rub it with the hand on which it should remain. white coating. Paste over whitewashed wall Do not use chalk or lime; the coating will not stick to such a surface. But if you remove everything unnecessary with a wet sponge or brush, the panels will hold quite securely.
• Enamel and oil paints do not react to water at all, they have a smooth, shiny surface.

Tip: Do not glue wallpaper onto an existing layer of oil paint. But if you follow certain surface preparation technologies, this can be done.

How to prepare a surface for wallpapering by applying oil paint to it

Before wallpapering with oil paint, all surfaces must be carefully inspected.

Wherein:

• The locations of cracks and loose layers are determined, which are often removed along with putty (see How to remove putty from walls and how long it takes) or plaster. Such defects cannot be left.
• Be sure to remove all nails and protruding elements, and dismantle the baseboards.

Tip: If after rough preparation half or more of the existing coating has been removed, the surface should be cleaned completely. If the main part of the walls inspires confidence, you can use special preparatory techniques.

• Before sticking wallpaper on oil paint, the wall needs to be sanded, as shown in the photo. It is known that the adhesion of oil paint to other coatings is very poor.

To enhance adhesion, a smooth plane must be made rough.

For this:

• Use coarse sandpaper to go over all the walls.
• The walls are treated with primer deep penetration(see Types of construction primers and their scope of application).
• The solution is left to dry for 24 hours.
• The cleaned areas are compared with gypsum-based putty (see Gypsum putty: its advantages and problems of use).
• Surfaces are washed with soapy warm water. This solution will wash away the grease, which will allow the paper to stick better.
• To enhance the properties of the composition, you need to add a small part of PVA glue to the wallpaper glue.

Tip: Before gluing the wallpaper, you need to coat the wall with a small layer of PVA glue diluted with water, give it time to “set” a little, but without waiting for complete drying, start pasting.

How to choose the right glue

Before gluing the wallpaper, the correct glue is selected.

It is better to purchase it for wallpaper with a large mass:

• Even for thin, single-layer material, a mixture is taken that is intended for vinyl wallpaper. It can be:

1. Bustilat;
2. Moment;
3. Methylane.

• If you are satisfied with the price, it is better to purchase PVA glue. Composition used:

1. in its pure form;
2. diluted with water in a ratio of 1:1.

How to prime surfaces

The main actions during surface preparation should be aimed at improving adhesion paper wallpaper on the wall, which consists in eliminating the property of oil paint to poorly absorb substances.

Work instructions:

• Purchase Concrete Contact soil or quartzite.
• The walls are washed and dried.
• The composition is applied with a layer thickness of approximately 4 millimeters.
• After drying, the surfaces are puttied with ordinary putty.
• The dried layer is again covered with a primer.
• The selected wallpaper is glued to the dried walls.
• You can make the primer yourself from those available and not expensive materials, which can be: PVA glue and
• alabaster.

For this:

• water is poured into the container;
• alabaster is added little by little, while constantly stirring the mixture;
• after the composition reaches the consistency of sour cream, PVA glue is added, and the ratio of the compositions is taken: for one part of glue - three waters.
• Well-washed walls are coated with a homemade emulsion and left to dry.

• To increase the adhesion strength of the wallpaper, you need to cover the canvases and walls with glue.
• Drafts should not be allowed during work and after it is completed. Windows and doors are tightly closed until the walls are completely dry.
• You should not stick wallpaper in hot or cold weather or in the presence of high humidity.

After preparing the surface, purchasing or preparing glue, the walls are glued.

For this:

• The height of the surface from floor to ceiling is measured.
• The length of the wall is measured and the number of required strips is calculated.
• The required number of strips is cut, the length of each is taken one centimeter longer.
• According to the instructions, glue is applied to the wallpaper. For different wallpapers applies different method applying glue.
• The first sheet is glued correctly. Before gluing it, draw a line with a pencil using a level, departing from the nearest corner the distance along the width of the wallpaper. This line will allow you to position the wallpaper correctly and evenly on the wall.
• You need to cover the room from the corner.
• The sheet should be glued from the ceiling, the upper joint is leveled and the sheet is pressed tightly against the wall with a rubber roller or a plastic spatula.
• The canvas is smoothed from the center of the sheet to its edges.
• Existing wrinkles are smoothed out and air bubbles under the sheet are removed.

Professionals do not recommend gluing wallpaper onto painted walls without removing the paint. But if such a decision is made, then it is necessary to properly prepare the surfaces.
