Expanded clay concrete blocks have many advantages, one of which is that their finishing does not require a long period of time. plastering work. Layer of plaster on concrete wall may not exceed 5-10 mm: this is quite enough to prepare it for wallpapering or other finishing work. But the question arises: which plaster is better to use?

For these purposes, both gypsum and cement-sand mixtures are used.

Gypsum plaster

The main advantage of gypsum plaster mixtures in relation to cement-sand ones, they are somewhat lighter and provide slightly higher thermal insulation. If you pre-treat the walls with concrete contact, their adhesion will improve.

However, some experts do without pre-treatment, applying plaster directly to. As practice shows, a high-quality mixture sets well and adheres without any problems even to an unprepared wall, especially since a number of plasters already contain concrete contact. The wall dries quickly, practically without absorbing the plaster, the layer remains beautiful and even.

Cement-sand plaster

Plaster mixtures are sand-based and are practically not inferior to gypsum in terms of thermal insulation. To ensure maximum adhesion to the wall, it is recommended to use a fine-mesh reinforcing mesh, which is attached to expanded clay concrete blocks using self-tapping screws. Again, there are specialists who do their work without reinforcing mesh, since cement-sand plaster mixtures adhere well to the wall.

However, such plaster is somewhat heavier than gypsum, so it puts a higher load on the wall. This point must be taken into account during work, especially if you plan to apply a relatively thick layer.

Cement-sand plaster also dries quite quickly and forms a smooth surface, ideal for subsequent finishing.

Use of expanded clay concrete blocks for installation load-bearing walls And interior partitions is becoming increasingly popular due to the low thermal conductivity of the material, which increases the efficiency of the entire structure. It should be noted that similar products do not have an ideal appearance, so the surface interior walls needs additional finishing.

One of the ways to level walls made of expanded clay concrete blocks is to install a layer of plaster, but the technology of work itself will differ from applying plaster to the surface brickwork. This is due to the fact that numerous spider-like cracks appear on the finishing layer during the drying process, and in some cases the mortar peels off. In this regard, it is necessary to follow the technology for laying plaster and select only high-quality expanded clay concrete blocks for this purpose.

Mortar for plastering walls made of expanded clay concrete blocks

The solution used must meet the following requirements:

  • sufficient strength, which will preserve the structure of the material from various kinds loads;
  • moisture resistance. Compliance with this characteristic will allow moisture to be retained on the surface of the wall, water will not penetrate the material, and this will preserve its durability;
  • good coefficient of adhesion to the base surface;
  • plasticity of the solution. Compliance of the plaster with this characteristic will help protect finishing layer from the appearance of cracks;
  • It is necessary to take into account the frost resistance of the material when laying plaster on the external surfaces of walls.

A mortar mixture that meets the specified parameters can be prepared independently from cement, sand and PVA glue with the addition of reinforcing fiber, or purchased in a store. In the latter case, you need to pay attention to the label - the solution should be intended for finishing expanded clay concrete walls.

Technology of applying plaster to expanded clay concrete

Next, we will consider the technology of constructing a plaster layer. First you need to clean the base from dust and dirt. After this, they proceed to puttying unfilled seams and cracks. The work must be carried out in such a way as to level the surface of the wall. On next stage work, after the plaster solution has dried, proceed to applying a primer to the wall. Such a solution will increase adhesion and help strengthen the base.

When the primer is completely dry, a reinforcing mesh is fixed to the surface of the wall, attaching it to the base using metal anchors with thin washers. Next, metal beacons are placed along the width of the rule. When carrying out such work, you need to use a building level and plumb line. The guide rails are fastened to the wall using gypsum mortar or regular cement mixture increased strength.

After the beacons have hardened, they are prepared plaster mortar, and then throw it into the gaps between the beacons; a ladle or trowel is used for this purpose. Next, you need to level the mixture with a rule and wait for it to dry. On final stage work, the beacons are removed and the surface is leveled. When finishing layer When the plaster dries, grout the surface using special trowels.

Buildings constructed from expanded clay concrete are finished in most cases, since an unprotected building will not be able to please its owners with durability. As a result of unfavorable natural phenomena unnecessary moisture appears in the space between the outer and inner base. And she, in turn, will destroy construction material. The external indicators of such blocks will not please with beauty, grace and nobility. How to clad a house made of expanded clay concrete blocks? This question is asked by a large number of people who are constructing such a building. The information below will help you resolve the issue.

Building finishing activities

You can clad a house made of expanded clay concrete blocks with the following materials: ceramic facing or clinker bricks, crushed stone, plastic molds, different types plaster. Taking into account the external nature of the finish, something should be said about the insulating layer.

In most cases it is installed with outside Houses. Thus, he is not able to reduce the area of ​​premises from inside. Helps protect walls and thermal insulation material from the appearance of condensation, which has a detrimental effect on the base of expanded clay concrete blocks.

The following samples are used as insulating components in the design of the external shells of a house:

  1. Polystyrene foam, which is one of the simplest and most popular bases.
  2. Mineral wool contains basalt fiber. Material of a similar nature long time holds its shape and is not subject to destruction.
  3. Fiberglass, characterized by low cost.

A house made of expanded clay concrete blocks, like buildings with other design options, is finished from the inside in the same way. To do this, use gypsum and cement-sand plaster. The possibility of decorating with clapboard, plasterboard, and plastic panels is also not excluded. Suitable for this option would be metal profiles and guide bars.

Wall cladding options

Natural stone or ceramic tiles are determined directly based on the need for preparatory work does not arise. For better fastening For these materials, use tile adhesive or a mixture of cement and sand.

As noted earlier, the buildings of the sample in question are not left bare, unprotected from the external influences of nature. Of course, if we are not talking about high-quality facing bricks. Despite the fact that buildings made of expanded clay blocks are lightweight, it is very important to correctly calculate the foundation. Therefore, the low weight of such materials does not provide grounds for constructing a lightweight version of the foundation. The disadvantage of such ceilings is their low thermal conductivity. Before facing external walls it is necessary to take care of carrying out warming measures.

So, mineral wool does not burn, a layer of plaster can be applied to it using a special mesh. The same cannot be said about mineral wool. It is intended for decorating a building with siding and other materials in the form of panels. Mineral wool laid under the siding must be protected from the wind. For such purposes, membranes are used that have the properties of protecting from wind and moisture. In this case, the insulation will be dry and provide reliable protection from rain and wind. There are also insulation materials based on mineral wool with a special durable layer on which plaster can be applied.

It is worth noting that the external decoration of the walls of a house with panels made of plastic or siding will not be such a complex undertaking, unlike finishing the surface with plaster. If plastering the base of a house can only be done by an experienced craftsman, then here you can do all the work yourself. Sometimes the method of painting walls without first plastering the surface is used, but it is used very rarely.

One of the frequently used options for finishing the external shells of a house will be ceramic, clinker and brick cladding. The least expensive option would be to treat the surface with a layer of cement-sand plaster. The latter finishing option, together with facade paints, helps to create original surfaces and an unusual appearance. Plaster has the best possible contact with expanded clay concrete; it is actively used for bases that constantly change under the influence of external temperatures and are periodically damaged. The façade, lined with natural stone, looks very beautiful and original. It is not afraid of frost, and at the same time it looks monolithic, chic and unusual. This material can be easily replaced artificial stone. It is no worse than the natural option, and it costs much less.

As a finishing option, thermal panels made of polyurethane and clinker tiles will complement the external shells of the house well. This finishing method can be called the least expensive. Panels of this type are lightweight and are often used for strip base. They are strong, environmentally friendly, and create a stable microclimate in the room regardless of the season. Installation work They are extremely simple; even a non-professional can do them.

Ventilated facades skillfully hide possible flaws in wall coverings. In the space between the wall and the facing layer there is a constant movement of air, as a result of which the base is not subject to destructive influence. Siding can be classified as inexpensive option decoration of external walls. However, such panels are quite fragile and can break, which does not reflect well on a wall made of expanded clay concrete. Houses made from this material can last a century, but it is important to choose the right finishing option so that the foundation is reliably completed.

Plastering expanded clay blocks

Choosing a mixture for plastering the facade of a building is not difficult these days. The compositions adapted to modern conditions have a very strong foundation. They do not crack and do not fall off for the next season. Once the plaster has been applied to the wall, it should be covered with any facade paint. Such enamel will protect the walls from unnecessary dampness and interfere with vapor permeability.

Plaster based on cement and sand is applied to the named types of blocks. It matches the masonry. To perform the work better, you can use a special mesh, but this is not a prerequisite. A galvanized mesh of a flat sample is placed on the cement base. It is secured with screws. The washers will be a zinc suspension with perforations, divided into plates. Washers of this type have minimum thickness, accordingly, will not increase the plaster layer. Such indicators are very important for some surfaces.

To make your work as easy as possible, plasticizers should be added to the solution.

Plaster made from a gypsum mixture is warmer and airier. It has lower density. To improve adhesion to the wall, it is treated with a composition intended for this purpose. There are ready-made gypsum plasters consisting of concrete-contact ingredients. No preliminary action is required for such reasons. Reinforcement is carried out by using a polymer mesh.

With all the possibilities of modern industry producing various Decoration Materials, it is better to choose between gypsum and cement-sand mortar. With their help inner part houses made of expanded clay concrete are plastered and brought to the desired condition. Let's consider both options.

Interior decoration of a house made of expanded clay concrete blocks using gypsum plaster noticeably easier in terms of work. Moreover, you get more warm house than with cement-sand mortar. Before applying the material to the walls, the working surface must be treated with concrete contact - this is done to improve adhesion and high-quality adhesion of the material to expanded clay.

There are often plasters on sale that can be applied without preliminary preparation walls using concrete contact. For best result it is recommended to use reinforcing material: polymer or steel mesh. In general, the polymer is even beneficial because it has higher performance characteristics.

Regarding cement-sand plaster, it is worth noting that its composition is not much different from ordinary wall material. This gives a significant gain in adhesive properties work surface. However, in practical terms, working with such plaster is somewhat more difficult than with gypsum.

Particular attention should be paid when using reinforcing galvanized fine mesh, as additional tools and special fasteners will be required.

To fix the mesh, you need to make small diameter holes in the wall with a puncher. Dowels are inserted into them and a mesh is placed, and then secured with self-tapping screws. It turns out that interior decoration expanded clay concrete blocks using cement-sand plaster is a more labor-intensive task.

External covering of a house made of expanded clay concrete blocks

Insulation of expanded clay concrete walls with fiberglass.

A house made of expanded clay concrete blocks, the plan of which provides for the outer covering of the walls, is fixed during their construction with a special mesh, reminiscent metal wire with a diameter of 3-4 mm. It is placed in a certain interval, after 2 rows of blocks. The mesh has a slight thickness, so the heat conductivity coefficient will remain at the same level.

External wall, finished facing bricks, connects with internal partition along the perimeter of the building. Many experienced craftsmen at the same time, 2 walls are built at once, one of which is the base, and the other is the finishing option. The laid mesh will not corrode.

A house made of expanded clay concrete blocks may have elastic plastic fasteners as options for securing the covering cladding. Here a ventilation opening is constructed, located in the space between the outer base and the layer to retain heat. A rod with a dowel sleeve and an anchor acts as a latch.

On main wall recesses are made at a distance of 50-60 cm vertically and 40-50 cm horizontally. Dowels are driven into them. The base, which serves the purpose of the heat insulator, is mounted on dowels and snapped into place with plastic clips.

A structure made of expanded clay concrete blocks, not insulated with material, involves connection with load-bearing structure clasps, that is, strips of steel base taking the shape of the letter “G”. The clamps are fixed at a distance of 50-60 mm.

The high performance of cladding buildings made of expanded clay concrete blocks is determined by the nature of the building materials used and the experience of the craftsmen.

Question: Good afternoon, dear gentlemen! Please tell us how best to decorate the outside of a house made of expanded clay concrete blocks (KBB), what facade would be appropriate here, what materials can be used? Arthur Shakarin, Novosibirsk

Answered by Semyon Fiskunov, Stroy-Alliance CJSC, Tolyatti.

Answer: Hello, Arthur! I'll try to answer your question in detail. Moreover, KBB is a fairly popular material; many owners build their houses from expanded clay concrete blocks.

First of all, I would like to ask you a counter question - how thick are the expanded clay concrete walls you built? The question is not an idle one.

It depends on your answer whether you will have to insulate your walls from KBB, or whether you can immediately do the finishing work external finishing and applying a decorative layer.

Insulation of walls from KBB

If you built the walls of a house from expanded clay concrete blocks in 1 block (this is 40 cm), then you will have to insulate it. For Novosibirsk and surrounding regions, insulation with 150 mm of basalt wool or polystyrene foam will be sufficient. This will give you standard indicator on thermal resistance of enclosing structures R according to new SNiP.

Ventilated façade on KBB walls

If you have chosen a ventilated facade and insulated your house with basalt wool, you can install it in wooden sheathing or into the space between steel hangers. I do not recommend you insulate a house made of KBB with polystyrene foam under a ventilated façade.

Why? Because there are several reasons why polystyrene foam is completely unsuitable as insulation for a ventilated façade:

    Styrofoam - flammable material, it cannot be used in systems with a ventilated facade. Rodents feel great in such a pie if you still make foam plastic into the ventilated facade. The movement of air in the ventilation gap and the moisture removed will eventually make a set of individual foam balls from the foam sheets. Your insulation will flow down the ventilation gap.

Basalt wool, which you can use, does not have these shortcomings in the ventilation façade. You can also use polyurethane foam, resole foam or ecowool.

After installing the sheathing or hangers and subsequent insulation, you can install the external decorative layer on the ventilated façade.

What is suitable in this case for a house made of KBB:

    Porcelain tilesClinker panelsVinyl sidingMetal sidingFiber cement panelsPlankenBlock house

These materials can be used to form a decorative layer in the ventilation façade for your home. How to install them - see on this website, everything is described in detail.

Wet facade on the walls of a house made of KBB

If you want to do wet facade on your house, then after preparing the walls (leveling, filling cracks, removing excess mortar), you can begin to insulate the walls of the house.

Can be used basalt wool density from 45 and façade foam plastic density from 25. Cotton wool is mounted on facade dowels, foam plastic is mounted with glue and additionally on facade dowels.

At the time of installation of the insulation, a façade fiberglass mesh is attached on top of it, which will reinforce the plaster layer. The mesh is attached with the same façade dowels with “fungi” that hold the insulation to the wall.

After installing the fiberglass mesh, a base primer layer or two-component plaster is applied. Next, the plaster is primed with penetrating primer. Modern façade systems allow you to maintain the plaster layer in a semi-plastic state, which guarantees its long-term operation.

After priming, you can prepare for applying a decorative layer or painting.

You can use the following decorative coating options:

    Painting with facade paintDecorative plaster bark beetlePlaster coatDecorative smalt plaster

After applying the decorative layer, you can use fixing compounds and facade varnishes. They will protect the decorative layer from contamination and possible destruction.

Under no circumstances should you insulate a house made of expanded clay concrete from the inside. Expanded clay concrete is actually a vapor-tight material. Moisture from the premises will be locked between the insulation blocks INSIDE the room. In this case, you will have all the adverse consequences - dampness in the room, mold under the insulation, and so on.

Expanded clay concrete blocks are in demand in modern private construction.

With it you can implement almost any project. But when the object is ready, the question often arises of how finishing work should be done. Houses made of ceramic blocks allow you to implement many tasks.

Exterior finishing methods

The main objectives of this stage of work are to improve the exterior of the finished facility, service life without major repairs, and heat conservation. The building's cladding protects the walls from damaging external influence. During construction load-bearing base space should be provided for future façade cladding.

Houses made of expanded clay concrete - insulation and finishing

External cladding carries not only a decorative, but also a practical load. Despite the fact that expanded clay concrete is durable material, capable of withstanding moisture, sharp temperature fluctuations contribute to the gradual destruction of the structure, it is also recommended to strengthen the wall with reinforcement.

The optimal brand of foam used for insulation is PSB-S-25. The thickness of the material should not be lower than 3-5 cm

Insulation

When working on the facade, the following must be taken into account:

    practice shows that one of best options the external finishing is the laying of a heat-insulating expanded clay concrete block, which compensates for heat loss up to 75%; additional insulation is mineral wool or foam plastic/expanded polystyrene; the foam plastic is fixed on the cleaned base using adhesive composition, additionally secured with dowels. All seams are treated with polyurethane foam; mineral wool requires stripping, gluing and reinforcement wall structures to increase the strength of the structure; the use of penoizol will achieve sound and waterproofing and reduce thermal conductivity.

Finishing

The basic principles of work are as follows:

    expanded clay block walls lined with bricks do not require additional processing, since they have a presentable appearance; you can use clinker tiles, stone (artificial or natural), thermal panels or siding; the most common option is to cover the walls with cement-sand-based plaster.

Natural stone looks noble and aesthetically pleasing, however, when choosing a material, you need to pay attention to its frost resistance. Brick is not inferior to stone in its functionality and aesthetics, but is much cheaper.

Facade work using thermal panels is an economical cladding method. The panels consist of polyurethane foam and clinker tiles. This is a lightweight material that showed effective application on strip foundations In addition, it is very easy to install.

Ventilated facade systems effectively cover all defects in wall structures and prevent their destruction. Siding can be fragile, and its damage during operation has a negative impact on expanded clay concrete masonry, which is confirmed by photos and reviews related to houses made of expanded clay concrete blocks.

Works with tiles or panel materials require the installation of sheathing. Finished design withstands dynamic and static loads

Wet facade on expanded clay concrete walls

The work is carried out after the walls have been leveled, all cracks have been filled with putty, and excess mortar has been removed.

Sequencing:

    first, insulation is laid, for which you can use façade foam plastic or basalt wool; the foam plastic is fixed with glue and façade dowels, cotton wool material - with façade dowels; façade fiberglass mesh is used as reinforcement, which is attached using the same dowels with fungi; two-component plaster is applied to the surface or a primer layer; the plaster is primed with penetrating primer; high-quality facade systems help maintain the plaster layer in a semi-plastic state, which guarantees long-term operation; after priming, you can begin preparing the surface for applying a decorative or paint coating.

Among all the options, you can use the following:

    decorative smalt plaster; “fur coat” plaster; decorative “bark beetle” plaster; painting with facade paint.

Facade varnishes or other fixing compounds are often applied to the decorative layer to protect the coating from possible destruction and contamination. Reviews for such houses made of expanded clay concrete blocks have been very positive.

Arrangement of plaster “under a fur coat”

Work can be carried out without insulation or on this layer. The method, known as finishing the facade “under a fur coat,” is carried out using spraying or spraying a solution. This method is less labor-intensive than working with other materials.

Created to work with the solution special devices. The device can be very simple, manually operated, or more technologically advanced, such as an air gun. At the construction site, the required mobility of the mixture is selected and finishing begins.

When choosing materials, you should initially evaluate the amount of work. The final finishing cost may be too high

House made of expanded clay concrete blocks - interior finishing options

The tasks of this stage of work are to protect the walls from adverse effects, model design solutions, environmental friendliness and comfort of housing. By choosing to build a house from expanded clay concrete blocks on a turnkey basis, you can get a building that is completely ready for use, with completed interior decoration.

Work can be carried out using the following materials:

    ceramic tiles; plaster; lining based on plastic or wood; wallpaper.

Application of plaster mixtures

This is one of the most economical and available options, which makes it extremely popular.

Working compositions can be as follows:

    decorative plaster – gives the surface a finished, aesthetically attractive look. Various textures and shades are available for sale, including glitter, stone chips, fabric fibers; starting - used to eliminate defects in the base layer; finishing - masks unevenness of the previous coating.

The working mixture is applied to expanded clay concrete wall with the participation of a special reinforcing mesh, with the exception of decorative coverings. To decide on the choice of plaster, you should focus on the humidity of the room. The most suitable are considered gypsum mixtures, providing aesthetic appearance and used for painting.

The use of gypsum plaster allows you to obtain:

    ease of work; a warmer house compared to solutions based on sand and cement; high adhesion, which is ensured by treating the wall with the “Concrete-Contact” solution.

Cement-sand mixtures have the following properties:

    the composition is not much different from standard wall material, which allows you to get an advantage in terms of adhesion to the working surface; practical application manipulations with such compositions are more labor-intensive.

Houses made of expanded clay concrete blocks, video - working with facing materials

If the owner is faced with the task of internal lining walls can be used a natural stone or ceramic tiles. No preliminary preparation of the base is required - the tiles are laid directly on the expanded clay concrete wall using cement-sand mortar.

Wallpaper coverings

To replace the standard paper wallpaper More durable and beautiful materials have arrived:

    non-woven; cork; vinyl; liquid wallpaper; textile.

This option finishing works implemented after preliminary surface preparation. The craftsman can carefully plaster the surface or cover the wall with plasterboard.

Expanded clay concrete withstands galvanized well steel profile or guide beam. The design of a cottage can be implemented in any style. The most popular are house designs made in accordance with the requirements of modern and classic design. IN country houses The “country” or “Provence” style looks especially organic. But, according to the reviews of the owners of houses made of expanded clay concrete, any design project can be easily implemented indoors. The features of a house made of expanded clay concrete blocks are described in the video.
