Build a house of aerated concrete without interior decoration. Materials for interior decoration of aerated concrete houses. In general terms, what is aerated concrete

A building made of aerated concrete can stand without exterior finish without any damage to the integrity of the blocks (we are talking about autoclaved gas silicate). But, over time, dust settles on the surface of the blocks, and the previously white outer surface becomes an untidy gray color with streaks. So anyway, sooner or later, but the question arises about the cladding or finishing of aerated concrete outside. Inside, aerated concrete is finished almost immediately after construction: the blocks in the interior do not look very attractive.

Since aerated concrete has a very high vapor permeability, there are certain nuances when carrying out finishing work. The fact is that almost all materials conduct vapors worse than gas silicate. This causes difficulties, since in order to ensure the normal removal of water vapor from the room, the vapor permeability of the walls - from the room - to the outside, must increase. Only special plaster mixtures for foam concrete meet this requirement. But subject to certain rules, the finish can be any.

Exterior finishing of aerated concrete

First, about how you can not finish. It is impossible to insulate with foam plastic or expanded polystyrene, plaster the outside with ordinary sand-concrete plaster, paint with covering film-forming paints. As a heater, if necessary, you can use mineral wool, paint with paints that do not block the pores for moisture to escape from the wall. Now about how you can finish the facade of foam concrete.

Hinged facades: lining, siding, panels, etc.

When finishing with any materials that are mounted on a crate or guides, a gap remains between the finishing material and the wall. It is called ventilation, since in this gap, with the right device, there is an active movement of air from bottom to top. The right device- this is the presence of holes in the finishing material at the bottom and top. This ensures the movement of air flow from the bottom to the top. This flow carries away moisture, which is removed from the room. Such a device solves the problem of condensate, and also maintains the normal humidity of the walls. Since aerated concrete has lower strength characteristics at high humidity, maintaining its normal humidity contributes to more long term"life". The dependence of the strength of aerated concrete on the percentage of moisture is shown in the graph.

When outdoor finishing aerated concrete with a ventilated gap, most of the time it has a moisture content in the range of 10-15%, i.e. is in the optimal zone. To create such a gap, a crate is stuffed over the entire area of ​​\u200b\u200bthe wall, providing a distance from the wall to the exterior finish of 3-5 cm.

For framing use wooden beam(treated with antiseptics), metal guides - galvanized profiles for drywall or special for ventilated facades. The frequency of the lathing is 40 cm. According to this principle, the aerated concrete facade is sheathed with lining, facade panels.

When fastening the crate to the wall, the question arises: with what, or rather, “on what” to fasten the crate to the gas silicate. You can just use self-tapping screws (black, they are stronger), but in order for the crate to hold well, you will need large lengths. This means that metal enters deep into the body of the block. In winter, it is an excellent cold bridge. But this is not the worst. Under wind loads, the frame vibrates, vibration, of course, is transmitted to the fasteners. Under the action of vibrations, foam concrete is crushed. As a result, the screw may fall out.

And that is not all. Due to the temperature difference - relatively warm aerated concrete and rapidly cooling metal of the self-tapping screw - condensation forms on the self-tapping screw. When the temperature drops, it freezes, destroying the body of the block. In general, just do not use self-tapping screws to attach the crate to aerated concrete from the outside.

To avoid such a situation, plastic plugs are inserted into the wall and dowel-nails are used. Ordinary ones are of little use, although better than just self-tapping screws. If you use regular ones, the length plastic stopper must be at least 30 mm.

In general, it is better to mount on special ones, which are called “for aerated concrete”. There are they in specialized stores selling hardware. They may not be found in the ordinary construction market. From the usual ones, they are poured over with a large size of the plastic part, as well as more developed screw plates.

The installation method is standard. A hole is drilled under the dowel plug (plastic part). Depending on the shape of the helical surface, a plastic insert is driven into it (in the photo, the upper dowel) or screwed (lower). Then the screw is screwed in.

When using wooden bars or galvanized profiles, they are attached to such dowels. The installation step of the crate is less than usual - it is about 40 cm. This is for a more even distribution of shock loads that occur during strong wind. An example of aerated concrete sheathing with siding can be seen in the video. There are many useful nuances.

brick finish

If you lay brick on the aerated concrete facade correctly, it will stand without problems for decades. Required condition- between the wall finishing material and a ventzaor should be a wall of aerated concrete. Its width is at least 30 mm. In order for it to work, when laying finishing brick air is left in the lower part - small holes into which air will enter. To prevent animals from getting into them, they are covered with ventilation grilles.

The principle of "work" of the system with a wall of finishing bricks spaced 3-5 cm

Only this type of finish, unlike ventilated facades, should be taken into account when calculating the foundation. Firstly, the mass of brick finishes, even half a brick, is considerable, and it must be taken into account when calculating the bearing capacity of the foundation. Secondly, the width of the finish is taken into account when determining the width of the foundation: the overhang of the brick cannot be more than 3 cm, and you also need a ventilation gap of 3 to 5 cm between the wall and the finish.

But, if you just put a brick wall at the required distance from the wall of the house, it is very likely that it will simply fall. Therefore, it is necessary to connect the walls of foam concrete and brick. To do this, even at the stage of laying foam concrete, thin plates are installed between the blocks, which are called "flexible connections". Best of all - if they are made of stainless steel. The environment in the solution in which these strips are sunk has an alkaline reaction, and in an alkaline environment, metal, even galvanized metal, quickly collapses.

Mounting plates inserted into the seams to bond with the foam concrete brick finish, but they are galvanized and after a few years the brick finish may fall off

The plates on the wall surface are placed approximately 60 cm apart in every second row, the maximum height distance between two rows is 50 cm. The plates are staggered. In the area of ​​corners, window and doorways should have them more often.

Sometimes, when laying, they forget about the plates. In this case, a dowel is screwed into the wall, to which a perforated metal plate or also a special stainless stud is already attached. Another option: during bricklaying, strictly opposite the seam, a hole is made in the wall into which a hairpin is hammered. The hairpin should go 10 cm into the concrete body and almost the entire width of the brick. But the hairpin is not flexible and can break both aerated concrete and brick trim (on the floor of a brick - for sure). Therefore, it is better not to suffer from such “economy”. How the aerated concrete is finished with the help of a finishing brick with a ventazor - in the video.

How to plaster aerated concrete facade

As already mentioned, plasters for aerated concrete can only be used with high vapor permeability. These plasters are expensive, but are applied in a thin layer. Therefore, a number of preparatory measures are required to obtain a smooth surface.

You can start plastering work when the humidity of aerated concrete blocks is not higher than 27%. Before starting work, the surface is treated:

  • dusted with a brush;
  • using a grater, the surface is leveled;
  • dents and chips are sealed with glue mixed with aerated concrete dust, which was obtained when cutting blocks.

The minimum layer - up to 10 mm can not be reinforced. Due to the adhesive additives in the composition, it will adhere tightly to the surface. If the layer is 10-15 mm, it is necessary to reinforce with a fiberglass mesh, with a thickness of 15-20 mm, a metal painting mesh is required. Exterior finishing of aerated concrete with plaster of greater thickness is impractical.

The grid for outdoor work should have a cell of the order of 3 mm. It must be resistant to alkaline environments (written on the package), otherwise after a couple of months it will lose strength and stop holding the plaster. As a result, the finishing layer will fall off.

Reinforcement is carried out along the applied layer of the primer mixture. It is also used special, has excellent adhesion to foam concrete, creates the basis for applying decorative plaster. The composition is applied to the wall in a strip. Until it freezes, a mesh is rolled onto it. Using a notched trowel or float, the mesh is pressed into the solution. After it has completely submerged, they take an ordinary wide spatula and level the surface, adding mortar if necessary. The leveled surface is left to dry. The term depends on the material used and is specified by the manufacturer. The average time is 7 days.

A primer is applied to the dried surface of the reinforcing layer. It performs several functions:

  • levels the absorbency of the base (reduces it);
  • paints over grey colour(she is white);
  • reduces porosity.

On a dried primer (available in the description), a finishing finish is already applied - decorative plaster. The technique of its application depends on the type of composition.

Insulation of aerated concrete walls

With normal calculation and observance of technology (laying on glue with a seam thickness of 1-2 mm), gas silicate walls do not need to be insulated. IN middle lane Russia sufficient block thickness of 325 mm. If, nevertheless, a need arose, the insulation must be vapor-permeable. And this is mineral wool and foam glass. Foam glass has excellent characteristics, but a high price. Mineral wool is cheaper. The thickness of the insulation depends on how cold it is in the house, but 50 mm is usually used as a minimum.

When finishing with a crate, it is made from a wider board or profile, taking into account the fact that the thickness of the insulation is also added to the thickness of the ventilation gap. Sometimes you may need a counter-lattice. These are additional strips, which, depending on the circumstances, are stuffed along or across the first crate. Thermal insulation is attached to the wall with special plastic dowels with a wide cap in the form of a fungus.

Internal finishing of aerated concrete

Finishing aerated concrete indoors has its own characteristics. Most often, such walls are still plastered. It is possible to use the same expensive mixtures as for exterior decoration, but it is very expensive. There are ways to make walls normally using ordinary cement or gypsum plaster. But this requires additional measures: a preliminary relief is created using cheap tile adhesive. It has good adhesion (cohesion) even with a relatively flat surface of aerated concrete, creates an excellent basis for applying subsequent layers. plasters. The procedure is as follows:


On the dried glue, you can apply plaster, or you can lay tiles. She is definitely not going anywhere: she will hold on well. In wet visits - bathroom, kitchen - you can choose a film-forming primer, which reduces the vapor permeability of paints.

For information on how to properly prepare a gas silicate wall for plaster, see the video. With its help, do-it-yourself plastering of aerated concrete walls is clear: everything is painted step by step and chewed.

Interior finishing options

Almost all options are acceptable for finishing walls made of aerated concrete inside:

  • Drywall or GVL on bars or profiles. There are no more difficulties with fastening: no wind loads, no frost. But, this is only when it comes to the house. permanent residence. In a seasonal unheated cottage and inside, the installation of dowels is required.
  • Lining in all its forms.
  • Plastic panels.
  • Painting, but on a prepared and leveled surface. And paints are still better with at least some vapor permeability. Unless in the bathroom or in the kitchen you can use film-forming compounds.

Of all these processes, only painting requires some explanation. Under this type of finish, an aerated concrete wall does not have to be plastered. In general, the walls should be almost flat. If there are chips, dents or protrusions, everything is solved very simply. They are sealed with the same glue on which the blocks were laid. If the dents are large, sawdust can be added to the glue, which are formed when cutting the block. The seams are rubbed with the same composition.

If there are protrusions, they are cut off with a special grater, but it can also be done with sandpaper fixed on a bar. These tools achieve a smooth surface that can be painted. The wall is cleaned with a brush attached to the holder - dust is swept away. The dedusted wall is primed. The primer is selected compatible with the selected paint. They must be compatible. It is advisable to apply the primer twice. Then, paint is applied on a completely dry primed surface.

Each year, the number of houses built from modern material- aerated concrete, growing. There are several reasons for this: low cost of materials and vice versa, high speed of construction, as well as availability and reliability. Dreams of owning a house for many are becoming a reality: the construction of the house has been completed, and now the question of repair arises.

Interior decoration aerated concrete houses. Peculiarities

Aerated concrete is a type of concrete that has many air-filled cavities inside. This provides high level isolation, which is very important for our country with a harsh climate. However, aerated concrete, in addition to obvious advantages, such as:

  • thermal insulation
  • Ease
  • Soundproofing

there are also disadvantages. Aerated concrete often dusts and crumbles - it is a soft and porous material, and also has a lower bearing capacity than, for example, brick. It is these qualities that determine the features of the interior decoration of a house made of aerated concrete with their own hands. By the way, such a minus as excessive softness of the material becomes an obvious plus when installing the GKL.

  • The limited bearing capacity means that the aerated concrete wall will only withstand a certain amount of mortar applied to it, which is used to level the walls. The conclusion is simple - the wall should initially be even, and the plaster mixture should be light enough when dried.
  • Due to the porosity of aerated concrete, you will need to use a larger amount of primer before applying the first coat of leveling compound to increase the adhesion of the mortar to the wall surface.

If you are planning the interior decoration of a house made of aerated concrete: photos of walls, characteristics of aerated concrete blocks and basic measurements of the room, this is what you should always have with you. When communicating with finishers and sales assistants in hardware stores, it will be easier for you to explain what and how much you need. Of course, it is always easier when there is a plan, an order of work, according to which it will be clear where to start finishing, what stages go one after another.

  • Determine what budget you are willing to allocate for wall decoration, what materials to use, what finish will be final in your home. After that, it is already possible to start purchasing materials and discussing work with the team that will carry out the repair.
  • Take measurements. If you do repairs yourself, then the hardware store will help you calculate the amount of material, if finishers work in your house, then take measurements and purchase required amount material can foreman.
  • After the preparatory stage, it is already possible and necessary to start decorating the walls, while the sequence of work must be strictly observed.

In order to make a competent and high-quality repair, you need to follow all the stages of finishing, in no case violating the technology.

  • Warming. An important point for the climate of our country, where most of the year the temperature is below zero, winds blow and cold rains fall. By insulating your home, you will also reduce your heating costs. The choice of heaters in the modern construction market is now great: polystyrene foam, polyurethane foam, mineral wool, mineral heaters.

  • Rough alignment. This is the layer that comes after the insulation layer or immediately on the aerated concrete wall, if the insulation was abandoned. Leveling can be carried out with drywall sheets, other types of panels or with plaster. This is the most important and large-scale stage of work, it must be carried out perfectly so that subsequently no cracks and chips appear.
  • Clean alignment. This is a pre-final finish, the task of which is to prepare the surface for applying a decorative coating. To do this, putties of various compositions (acrylic, gypsum) are used, which eliminate all small irregularities, cracks, pits.

  • Primer. Priming is carried out after each stage, if required by the conditions of use of materials. The first coat of primer is applied directly to the aerated concrete wall to reduce it, make it less porous, create additional adhesion and reduce the absorption of the plaster solution.
  • Decorative trim is the final. Here you already give free rein to your imagination, which will be limited only by financial capabilities.

Options for interior decoration of a house made of aerated concrete

When deciding how to make the interior decoration of a house out of aerated concrete, remember that absolutely any material used in wall decoration can be the finish, your task is to choose the rough finish method. The first step is the rough alignment of the walls, it can be done in the following ways:

Plaster. This method has been used for centuries for wall decoration, of course, it has its pros and cons, but the final result, in any case, will depend on compliance with the technology and the quality of work. The plaster is applied in several stages, after each there should be a slight drying, and after completion of the work, the walls should be dried for several weeks.

  • Cleaning the aerated concrete wall from debris, dust. This will help improve the adhesion of the wall and mortar.
  • Spray. This method is used to increase the strength and reliability of the coating. The solution for leveling the walls is diluted with water and sprayed onto the wall with a brush or broom.
  • Primer. After the spray has dried, a primer is applied, which isolates the aerated concrete, closes the pores on it and creates a connecting layer. The primer must dry well to get the desired effect.

  • Application of the first layer. The first thin layer is applied to align the seams between the blocks, overlap the chips and recesses, and it also acts as an adhesive layer for the reinforced mesh.
  • Laying reinforced mesh. To prevent cracking and settling of the plaster layer, a reinforced mesh is used. It is applied over the first thin layer and imprinted into it, after which it is slightly leveled with a spatula.
  • The application of the main layer of plaster is called - nakryvka. It already completely levels the walls, creates a flat surface without dents and bumps.
  • smoothing down. After applying the main layer, it is necessary to let the plaster “grab”, after which, by smoothing, the surface is leveled with application, making it even.

When all the work on plastering the walls is completed, it is necessary to dry the walls. Each centimeter of the applied solution dries for 1-2 weeks.

Drywall. This is a recently appeared clean and fast way to level walls. Aerated concrete is a very soft and porous material, so dowels and self-tapping screws easily enter it, you do not have to use a hammer drill or a powerful drill.

  • First, fix aluminum or wooden rails in the wall, remember that the step between them should not exceed 5 centimeters.
  • Drywall sheets are attached to the guides. To do this, use standard screws and a screwdriver. If necessary, drywall can be easily cut with a simple one.

After applying plaster or installing drywall sheets, it's time to finish the walls. With its help, they get rid of all the shortcomings of the railing, remove cracks and chips, prepare the wall for applying a decorative coating.

Tips for self-finishing walls in an aerated concrete house

  1. Start work on finishing the walls no earlier than 2-3 months after the construction of the house.
  2. If you are using plaster, carry out finishing work in warm time of the year. Drywall is good because its installation can be carried out at any time.
  3. Choose a ready-made mixture for plastering walls, it is more uniform and has an ideal consistency.

Very good interior decoration of the house made of aerated concrete video, which we present below.

Proper and high-quality wall decoration in aerated concrete house will make it cozy and beautiful.

One of the main problems after building a house of aerated concrete is to determine the optimal finishing material for interior decoration. So that the walls are not exposed to adverse influences, it is worth knowing in advance about the types of interior decoration of such material.

Features of finishing walls made of aerated concrete

Aerated concrete has a high vapor permeability. This suggests that when the air temperature drops in the thickness of the wall of aerated concrete blocks, moisture accumulates in it. To ensure the safety of the material, the vapor permeability of the wall must be reduced.

The best way to reduce vapor permeability is to impregnate the walls of aerated concrete blocks with a primer, apply a layer of cement plaster. This happens in several stages:

  1. Impregnation of the surface of aerated concrete blocks with a deep penetration primer. In this case, it is worth applying these compositions in several layers.
  2. Application of cement plaster.
  3. Primer plaster.

Finishes

by the most in a simple way finishing is the use of frame materials. An example is plastic or drywall panels. The simplicity lies in the fact that for finishing it is not necessary to align the walls of aerated concrete blocks, it is enough just to fix the panels on the frame.

Finishing materials such as wallpaper are also often used. Before their gluing, the walls are leveled and the base for the wallpaper is applied. All these processes will require a large amount of materials, and after the repair, you will have to remove the dirt left after the surface is plastered. That is why many owners of aerated concrete houses choose frame materials.

Finishing with plastic panels

In a house with walls made of aerated concrete blocks, the frame for finishing materials is created in two layers. The first is for waterproofing, and the second for panels. For the frame, bars with a section of 25x25 mm are needed. Installation begins with fixing the bars to the floor and ceiling.

Important ! All bars must be installed in the same plane so that the wall of aerated concrete blocks is even.

After installing the upper and lower bars, the threads are pulled, which serve as a guide for installing additional elements. Intermediate bars are installed along the stretched threads, the distance between which should be about 50 cm. Each element is fixed using self-tapping screws.

If you have no experience in decorating rooms with plastic panels, you should purchase start and finish profiles. They are made of plastic and contribute to a more accurate installation of the panels. They are fixed with a stapler or small nails.

Important ! After installing each panel, it is necessary to check whether they are installed evenly on the frame.

wall painting

Before you buy paint for interior decoration, you should carefully consider all the compositions presented, as they are designed for different conditions. The most common are water-based formulations. This is due to the fact that such material is not expensive and can be applied to the walls by an inexperienced person. But at the same time, it is worth remembering important points:


Water-based compositions are applied to the wall of aerated concrete blocks in several layers. In this case, the first layer must be applied not in a horizontal plane, but from top to bottom. The peculiarity of water-based paint is that when applying the second and subsequent layers, you do not need to wait until the previous one dries. Such compositions can be used in rooms with high humidity, as they withstand exposure to water.

Using wallpaper

Wallpaper can be used to create both classic interior, and for decorating the house in the original style.

Often used:

  • non-woven materials;
  • vinyl wallpapers;
  • washable.

The popularity of such finishing materials is explained by the fact that when using them, you can choose almost any design style. But it is worth remembering that before sticking wallpaper, you need to level the surface of the wall, and also apply plaster on it.

Wall linoleum

Linoleum for floors is considered a versatile material, as it is used in both residential and public buildings. Linoleum for walls has appeared relatively recently and therefore is one of the least popular materials. But it is increasingly used in home interior decoration, as it has the following advantages:

  1. Hygiene. Linoleum does not absorb moisture, so fungi do not appear on the walls.
  2. Ease of care. Linoleum for walls can be washed and not worry that it will deteriorate. At the same time, the coating withstands the effects of household chemicals.
  3. Strength. It is quite difficult to spoil the surface of wall linoleum. At the same time, it withstands strong blows, which cannot be said about the tile.
  4. Ease of installation. You can fix the material even without the skills of finishing the premises.

The disadvantages of the material include its high cost. It is also worth noting that you can not find it in all hardware stores.

Plaster

This finishing material is quite popular and allows you to create a different design of rooms. The advantages of plaster include ease of care for the material and a long service life. Interior decoration of aerated concrete walls is as follows:


What material to choose

To make a choice, you should first think about the operating conditions. It is also necessary to choose the right characteristics of the material. The color of the finishing material should match the overall design of the apartment. If a small amount of light enters the room, it is worth making the walls light.

To create a business style, it is better to use either materials that imitate wood. It is worth remembering the operating conditions of the premises. In the corridor, for example, you should not install materials that can easily be damaged by accidental touch.

Due to the fact that for finishing walls made of aerated concrete can be used various materials, the owner of the house can make a choice based on their own preferences. Having considered all the options presented, you can easily choose exactly the material that you like.

Aerated concrete in the construction industry has won its place due to its good strength and bearing capacity, excellent heat and sound insulation characteristics. He has one property that repels a certain part of private developers from using this material - high water absorption, reaching up to 85%. But this problem today is solved quite simply. To do this, you need to use only one of the finishing materials. This applies mainly to the outside of the building. But the interior decoration of the house made of aerated concrete is no less important process which must be treated with full responsibility.

Interior finishing options

There are a huge number of materials with which you can finish the walls of aerated concrete. We can say that the decoration of the house from aerated concrete blocks is not limited by anything. Of course, there are technologies in which traditional materials are not used, but special ones are used, designed specifically for cellular concrete. This primarily concerns "wet" technologies. With them, we will begin the analysis of the issue, the better to finish the walls of aerated concrete.

Plaster

This is a traditional technology for interior wall decoration, which has long been known and developed. Manufacturers of plaster mixtures offer various varieties of this material, which are divided according to the variety of the binder. These are mixtures of cement, lime and gypsum.

It should be noted right away that the first option for finishing aerated concrete walls from the inside is not used, because for cement plaster it is important that the walls do not quickly absorb water. And with aerated concrete, this will not work. Consequences - cracks throughout the plaster layer, partial or complete delamination of the mixture from the wall.

It should be noted that cement mortars in the finishing of aerated concrete, they are still used, but not in their pure form, but with special additives that retain moisture inside the finished mixture. Manufacturers on the packaging of such materials must indicate that they should be used for aerated concrete.


The process of plastering walls made of aerated concrete is no different from traditional technology. I.e:

  • surfaces must first be primed with primers for aerated concrete (such are made with the addition of special additives),
  • then a synthetic plaster mesh is applied and fixed on the wall,
  • and the last - the mixture is applied, and the surface is leveled to the required thickness.

This applies not only to cement plasters.

There is an easier option. For this, thin-layer plaster mixes are used. They are applied directly to the wall with a thickness of not more than 8 mm without installing a reinforcing mesh. Aerated concrete blocks have a flat surface, so wall differences are minimal. So, this option is acceptable as optimal and inexpensive.


Tiling

This refers to any tiled material, more often tiles and stone. The stages of interior decoration of aerated concrete walls with these materials include preparation and installation itself. The preparatory process includes only cleaning the wall from dust and priming. If there are chipped blocks on the inside of the wall, then they are filled with repair mortar or putty before priming.

The process of installing tiles from the traditional is no different. The cladding is laid on the adhesive composition, leveling in planes. There are no restrictions on stacking height.

Plasterboard finishing

We turn to dry technologies for interior decoration of walls made of aerated concrete blocks. And the most commonly used option is drywall finishing.

Regardless of the material from which the wall of the house was built: aerated concrete, brick, wood, etc., the technology for installing gypsum board sheets from the traditional frame does not differ. That is, a frame made of metal profiles is mounted on the wall, on which plasterboard panels are attached. The only difference between aerated concrete blocks and all other wall materials is its porosity. The standard plastic dowels installed in them will not hold in the body of the material. Under the influence of the weight of the overall structure and the vibration of the building, the dowels will begin to move inside the mounting hole and, as a result, will pop out of it.

For fastening the frame structure inside the blocks of aerated concrete, it is necessary to use special dowels designed for cellular concrete. There are two types of them, screwed and driven. The first has two subforks: straight and cone-shaped. Both options have a wide thread in the design, which allows you to firmly cut into aerated concrete material. There is a third option - chemical dowels in the form of a special solution that is pumped into the mounting hole. It polymerizes inside under the influence of air, forming a strong cork.


The sequence of interior finishing with plasterboard sheets is as follows:

  • two guide profiles are installed: one on the ceiling along the wall, one on the floor, located in the same vertical plane;
  • a metal frame is mounted from vertical racks with their fastening on direct suspensions and installation of the ends in guide profiles;
  • installation of crossbars between racks to increase the reliability of the structure;
  • laying and fixing drywall on the frame;
  • puttying the entire surface of the finish to level minor differences and cover the seams.

This type of wall decoration made of aerated concrete indoors according to the installation technology is not much different from the previous one. Here it is also required to assemble a frame on the wall in the form of a crate of vertical or horizontal profiles. Instead of the latter, you can use wooden slats with a cross section of not more than 50x50 mm, which must be very dry and treated with an antiseptic composition.


If plastic panels will be mounted vertically, then the elements of the crate are installed horizontally in increments of 50 or 60 cm. If horizontally, then the frame is laid vertically.

It is necessary to pay attention to the fact that special dowels for cellular concrete are used for this cladding option. The panels themselves are not assembled butt-to-butt, like drywall sheets, but with the help of lock connection"groove-thorn". If the panels are mounted horizontally, then the material is assembled with the spike up. Self-tapping screws are screwed into the cladding into the panel groove, which is closed with a spike of the next element. Therefore, fasteners from the outer front side are not visible.

Finishing PVC panels- This is an option for wet rooms: kitchen, bathroom or toilet. But when the question of finishing the bath inside is raised, plastic panels are not used. They just can't handle the high temperatures. For these purposes best option- lining.


Clapboard finish

The interior decoration of gas blocks with clapboard is a frame version of wall covering. Only in this case they try not to use metal profiles. If we talk about some distinctive features installation technology, they simply do not exist when compared with PVC trim.

That is, the lining is assembled on a crate (vertical or horizontal), which is pre-treated with an antiseptic. Here it is important to choose the right finishing material. It must be dry with a minimum number of defects.

Features of finishing aerated concrete

There are a huge number of options for interior decoration of a house made of aerated concrete. The above technologies are just a part. What you need to pay attention to when choosing one or the other.


Classic today building materials hard to compete with modern technologies, with which you can build durable and high-quality buildings. Every year, the use of gas blocks is becoming more and more popular. If many do not have questions with the external processing of the material, then the interior decoration of a house made of aerated concrete requires a more detailed study.

Material Features

Before you start finishing the walls of aerated concrete indoors, you need to navigate in characteristic features material. The basis for the production of gas blocks are cement, sand and lime. The technology provides for the addition of aluminum shavings during the production process. The resulting solution is poured into special forms. You can use the material after complete solidification. Aerated concrete has gained popularity due to its positive properties:

These advantages of the material allow its use not only for creating external walls, but also for the construction interior partitions. The disadvantage of gas blocks is the vulnerability to moisture, as a result of which the interior decoration should be carried out using materials with increased moisture resistance.

Surface plastering

When interior decoration of walls made of aerated concrete, it is necessary to use materials with certain qualities. In buildings made of gas blocks, there must be a certain humidity, and decor materials should not change these indicators.

A popular type of finish is gypsum plaster. It is characterized by a significant degree of permeability. The tool can be purchased at hardware stores in dry form. Dilute the mixture with water according to the instructions.

In addition to gypsum, slaked lime and sand are included in the plastering composition. It is these components that contribute to the improvement of soundproofing and fire-fighting properties. The use of gypsum plaster does not imply a preliminary priming of the walls. A feature of the material is that after the composition has dried, it is not necessary to apply a layer of finishing putty.

The disadvantage of the mixture is the high price. An alternative option could be a classic sand-cement mortar. Step by step preparation walls made of gas blocks for plastering:

  • First you need to prepare the surface. We should not forget about the high moisture-absorbing properties of the material. Having got rid of possible defects, it is necessary to treat the surface with a special primer, which has deep penetration. It is necessary to apply the composition in two layers.
  • Then apply a layer of tile adhesive, 3-4 mm thick.
  • To provide additional adhesion of materials, you can use a special building mesh with small cells. It must be fixed with uncured glue.
  • Then, with a notched trowel, form a surface relief.

After carrying out the manipulations, let the walls dry for several days. Next, you can start finishing with plaster. It should be noted that tiles can be laid on the walls prepared in this way.

Finishing sheets of drywall

Drywall is one of the versatile materials used for finishing. It is suitable for processing any walls, including aerated concrete.

It should be noted that drywall is standard, fire resistant, combined and moisture resistant. Which one to choose for interior decoration of walls made of aerated concrete, each owner decides for himself based on the characteristics of a particular room.

When working with the material, both manual and electric tools will be required:

Before proceeding with the finishing of drywall, it is necessary to carry out calculations with which you can determine the required amount of material. To do this, you should calculate the area of ​​\u200b\u200bthe room, select the type of drywall and decide on the scheme of the crate.

Often there are situations when sheets are glued directly to aerated concrete. But there is a more popular method when drywall is attached to a pre-prepared frame made of metal or wood. The advantage of this method is the possibility of additional insulation of external walls.

During installation work with the frame, guides are first installed around the perimeter of the room, which are located both vertically and horizontally. Then, at a distance of 50-60 cm, vertical slats are fixed, but it all depends on the height of the ceiling. These guides are sufficient for a wall height of 2.5 m. If the value is greater, it is recommended to carry out horizontal fastening.

To fix the guides in the walls, dowels are often used. For normal air circulation in the room, the crate should move away from the wall by 3-5 cm.

When the frame is ready and fixed, you can start fastening the sheets. First, one-piece structures are mounted. If you do this consistently, you can avoid many difficulties. The frame and sheets are connected with self-tapping screws. It is necessary to ensure that the edges of the drywall are placed in the center of the rail. After fixing all the sheets, it is necessary to process the joints and holes from the self-tapping screws with a thin layer of finishing putty.

Using lining or plastic

The fastening of these materials to the wall is carried out in the same way, since the cross sections on plastic panels and wood lining are almost the same.

The materials have tongue-and-groove joints. This results in an almost completely sealed surface. For safety net, you can pre-treat the walls with a vapor barrier film. It should be noted that when using plastic in rooms where high humidity is recorded, it is required to equip exhaust ventilation.

Installation work you need to start by installing the frame. The process is similar to the design for fixing drywall sheets. You can use both a metal profile and a wooden beam. Many experts advise using metal structures, due to the lower cost and lightness of the material compared to wood.

The fastening of materials directly depends on the type of frame, and can be carried out using clamps, nails or self-tapping screws. Thanks to the crate, the finished surfaces are perfectly flat.

When the frame is ready, you can start attaching the sheets. First, the first bar is fixed by a spike on one side and a groove on the other. Each next sheet slides into the groove of the previous one, the edge of the groove is again fixed on the frame.

Corner panels are fixed along the edges of the walls. These manipulations are optional, but with their help, the corners look more aesthetically pleasing.

Aerated concrete painting

Another option for the interior decoration of aerated concrete walls is surface painting - one of the oldest methods of decorating the walls of a dwelling. Before the staining process, a number of manipulations must be performed.

The surface to be painted must be perfectly flat. For this, special grinders are used. In the absence of the latter, the walls are leveled with a special grater or emery. The need for these procedures is explained by the fact that paint coatings are unable to hide possible wall defects. If there are larger flaws, you can get rid of them with tile adhesive. After drying, the surface must be carefully rubbed.

Any painting involves the preliminary application of a primer coating. Of course, the priming and drying of the composition will take some time, but due to the manipulations, the coating will be even. For interior decoration of a house made of aerated concrete blocks, water-based paint is often used. With the help of color you can get the desired color and shade. It is necessary to start the staining procedure from the far corners of the room.

There are some tricks that are used when painting walls. The paint must be applied in several layers, crosswise. For example, if the first layer is applied vertically, the next layer must be applied horizontally, etc. When working with water-based paint no need to wait for the layers to dry.

Fake diamond

Now many people prefer this type of finishing material. This is due positive characteristics stone:

The cost of artificial material is much lower than natural. The stone can be of any size and shape. Installation work must be carried out on a flat surface so that the quality of the finish is high. Before starting work, you need to prepare tools and materials:

  • special glue;
  • level;
  • putty knife;
  • container for the manufacture of adhesive composition.

Mounting process artificial stone pretty simple. The adhesive solution must be applied both to the part and to the wall. Press the material to the surface, making small turns to release the accumulated air. Remove excess mixture with a spatula.

At the end of the finishing work, wipe the seams, if necessary. Even a novice master can carry out work on laying stone.

When buying materials for processing walls from gas blocks, it must be borne in mind that the characteristics and service life are directly proportional to the quality. Therefore, when choosing building materials, you do not need to save money, because the wall decoration inside the house will last for many years.

It is advisable to make purchases in specialized stores where you can see quality certificates for the products offered. Buying a cheaper product in non-specialized outlets, a person should be aware of the possible risks.

When choosing building and finishing materials, it is desirable to give preference to any particular manufacturer. The quality of the coating will be much better from this.

Excessive moisture absorption of aerated concrete blocks forces owners to be scrupulous in the choice of materials. Very often in such situations, several types of finishes are used. For example, when combining plaster and wallpaper, the required vapor permeability is created in the room. The latter has a positive effect on the overall microclimate of the room.
