How to finish the interior walls of aerated concrete. Options for finishing aerated concrete walls inside

Comments:

There are a lot of methods by which interior decoration of a house made of aerated concrete can be carried out. But in any case, one should take into account the specific properties of cellular concrete, the main enemy of which is moisture. Due to the hygroscopic nature of the material, water entering the aerated concrete wall from the atmosphere penetrates into the pores, worsening its thermal insulation characteristics and limiting natural ventilation.

Despite the many options already mentioned, finishing houses made of aerated concrete should provide two absolutely mutually exclusive conditions:

1. Housing cannot be comfortable if a high degree of vapor permeability of the walls is not ensured. Only in this case, its microclimate will have a beneficial effect on the human body.
2. The high hygroscopicity of aerated concrete leads to its rapid wear with a significant penetration of moisture into the blocks. A vapor barrier is required, that is, a vapor-tight finish.

To ensure their simultaneous provision, the following rule must be strictly observed: it is impossible to finish the outer walls with vapor-tight materials, and the inner ones with vapor-permeable materials.

Aerated concrete interior walls

It is believed that the creation of a vapor-tight coating on a wall is a relatively simple task. For example, vinyl wallpaper will reduce this figure many times over. A similar effect is obtained by laying a conventional polyethylene film on the wall. But in this case, one should take into account the likelihood that condensation may form under the film, which adversely affects aerated concrete.

Traditional sand-cement plaster also improves vapor barrier tenfold. However, there is an unpleasant nuance here - due to the high hygroscopicity of the wall material, such plaster often peels off over time.

Gypsum plaster adheres well to cellular concrete. It consists of the following components:

• special (perlite) sand obtained from volcanic rocks;
• slaked lime;
• alabaster (building plaster).

Since this is a vapor-permeable coating, the problem is solved by combining materials. First, the wall is primed several times, and the previous layer of soil must dry completely. This treatment greatly reduces the vapor permeability of the surface. Gypsum-based plaster is applied over the primer, after which it is possible to finish with any suitable materials.

Interior decoration of the house with frame materials

This finishing method is considered to be one of the simplest. Indeed, preparing walls for painting or wallpapering is a costly, lengthy and messy process, since you cannot do without a number of tedious operations:

• surface leveling;
• their careful and high-quality smoothing;
• hardening of these surfaces.

All these operations require many different building materials, time and qualified performers. With drywall, decorative and plastic panels, which are frame materials, things are much simpler.

First of all, you need to worry about the hydro and vapor barrier of aerated concrete walls. The easiest way is to make a wooden frame from slats or bars with a thickness of 25 mm. Initially, the slats are attached to the wall near the floor and ceiling. Their presence in the same vertical plane is controlled very strictly and carefully.

Between these bars, several strings are pulled, showing the plane of the finish. They control the fastening of intermediate bars to the wall. The distance between the rows of bars is 50-60 cm. The frame bars are attached to the wall using self-tapping screws.

Each sheet of frame material should have three frame rails: two at the edges and one in the middle. Sheets are screwed to the frame with special self-tapping screws with countersunk heads. The distance from the screws to the ends of the sheet must be at least 1.5, and to the longitudinal edges - 1 cm. They must enter the facing material at a right angle.

Since wood, due to its sensitivity to humidity and temperature, is not suitable for every room, often not a wooden frame is used, but a metal frame made of galvanized steel.

Sometimes such facing materials are attached to the walls in a frameless way using special glue. If the wall is sufficiently even (differences in irregularities are not more than 5-6 mm), then the adhesive is applied to the sheets in a continuous layer, otherwise it is applied in the form of heaps along the perimeter and middle part of the sheets.

Interior decoration of the house by painting the walls

It is widely believed that painting is a very simple way of finishing that anyone can handle. This simplicity is apparent, especially if the house is new. There are several reasons for this:

1. The wall must be well prepared for the upcoming painting - level its plane and achieve a high degree of smoothness. Without tedious processing of the wall with a fine sandpaper and its subsequent priming, this cannot be achieved.
2. Obtaining the desired color shade by adding color is a rather difficult task for a non-specialist.

There are a lot of building paints, they differ in composition, properties and their purpose. Before purchasing paint, it is highly advisable to consult with a specialist about the degree of its applicability for wall decoration inside the house.

When using oil paint, the degree of vapor permeability will still significantly decrease. Recently, this finishing material has practically not been used to finish the house from the inside, and the most common option for walls is water-based paint - a high-quality, inexpensive and affordable material for interior decoration.

A few tips for its use:

• the wall should be covered with paint in 2-3 layers;
• with a two-layer coating, the first layer is applied with horizontal strokes, and the second with vertical strokes;
• with a three-layer coating, the first and third layers are applied vertically, and the second - horizontal strokes;
• it is not necessary to wait for the previous layer to dry, the water-based emulsion is applied wet.

Recently, the use of water-based acrylic paints has been expanding. They are easy to apply, do not change color over time, and are not a source of toxic substances. A great option for those who doubt their artistic taste and design abilities.

Interior decoration of the house: other types

The modern building materials market is distinguished by enviable diversity. For interior decoration, you can find many suitable options. Here are just a few of them:

1. Wood is the most warming material not only for the body, but also for the soul. It is used for interior decoration in the form of panels, lining, semi-logs. And if it is coniferous wood, then it will serve longer, and the house will be filled with useful phytoncides.
2. Natural and artificial stone has recently become a very popular finishing material. Used to decorate kitchens, hallways, living rooms and even bedrooms. Preliminary preparation of the walls is optional, no special laying skills are needed, beautiful, durable and strong, what else do you need?
3. Ceramic tiles as a facing material should be used in rooms that have a high level of relative humidity. This choice implies the organization of effective forced ventilation.
4. Wallpaper is one of the most common ways to decorate walls. Over the past years, many new solutions have appeared, and an endless variety of colors allows you to dress the house in a truly beautiful, comfortable and environmentally friendly wallpaper.

A wide range of building materials, when choosing the prevailing in the form of aerated concrete, makes it possible to combine several types of raw materials. The facades of walls made of aerated concrete blocks can be finished with facing bricks or siding, and for internal partitions, foam concrete, aerated concrete, cellular concrete can be used, followed by finishing with a huge amount of materials on the market. When building any walls from aerated concrete blocks, the thermal insulation of the premises is significantly increased, and the interior decoration of a house made of aerated concrete rests only on the choice of suitable textures and the convenience of working with finishing building materials.

The most voluminous internal work is the plastering of aerated concrete walls. Few people know how to do this correctly on an aerated concrete surface. There are certain rules and technologies that ensure the integrity of the cycles of circulation of air masses in the house and through the walls, and plaster based on gypsum or alabaster is preferred here.

Aerated concrete is prepared by mixing high-quality Portland cement, lime and refined sand. The main component that turns an ordinary mortar into a light and porous building material is aluminum chips or powder, which causes air bubbles to appear in the working mixture. The solution poured into special forms must harden, after which the blocks are ready for use.

Advantages of aerated concrete blocks:

1. High rate of thermal insulation qualities;
2. Absolute fire resistance;
3. Good noise canceling performance;
4. Frost and moisture resistance, preventing the formation of condensate in the material and the occurrence of fungi and mold;
5. Long-term operation of the building from gas blocks;
6. Easy machining, light weight.

The above characteristics provide ample opportunities for the use of aerated concrete bricks indoors, since such blocks are easier to finish. When choosing materials for finishing interior work, pay attention to mutually exclusive points:

1. A comfortable microclimate in the house is maintained at a certain level of humidity, and it should be limited by the use of appropriate finishing materials to a level acceptable for aerated concrete surfaces;
2. The hygroscopic properties of intermediate layers of finishing materials have a significant impact on their resistance to wear. Therefore, so that excess moisture does not penetrate into the block, a layer of vapor-tight material is equipped. Such a substance is gypsum plaster, as well as wall decoration with moisture-resistant drywall, followed by plastering.

The vapor permeability of gas blocks can be reduced by almost ten times with vinyl wallpaper pasted over plaster or puttied with plaster. In addition to the commercially available dry plaster mixtures such as Knauf or ABC, walls can be finished with the usual mortar of cement and sand with stabilizing additives. But in rooms with high humidity (bathroom, bathroom or kitchen), the walls can periodically become damp and cause peeling of the plaster layer. Therefore, to improve the vapor barrier characteristics of walls, a combination of building materials is used, and it can be very diverse.

For example, an aerated concrete wall is opened with a layer of primer, after drying, two more layers are applied, and then the wall is plastered with gypsum mortar. On top of the gypsum layer, you can begin the design of the finishing (decorative) finishing layer. Materials for this are also selected "breathable". So, instead of oil paint, it is not recommended to use acrylic or water-based paint to decorate a country house inside without reducing the vapor permeability of the walls.

Preliminary work before finishing

The main rule for finishing aerated concrete walls is to start with internal walls and partitions. Exterior decoration, if necessary, can be completely excluded, or the minimum necessary operations can be carried out, but only in warm and not rainy weather.

The production cycle of aerated concrete blocks does not provide for complete drying of products, and the blocks have a moisture content of ≈ 30%. But finishing the walls of aerated concrete in the house can be carried out if the humidity of the walls reaches a threshold of 15%. Therefore, it is advisable to start internal plastering while the outer surfaces evaporate excess moisture.

Surface preparation consists of cleaning the walls of debris, dirt and excess mortar, as well as leveling large irregularities and patching potholes. Cleaned gas blocks are primed from floor to ceiling in 2-3 layers. Before the start of plastering, vertical beacons are installed - a metal perforated corner with a stiffener - after 0.7-0.8 m, along the width of the spatula or rule. The layer of plaster mortar is observed in the range of 0.4-0.8 cm. Beacons are left in the plaster, and before the finishing layer of the building mixture, a fiberglass mesh is attached to the wall, along which the walls will be plastered with CM-10, CM-11 or Ceresit.

How can you decorate aerated concrete

Decorative finishing of the external aerated concrete surface is carried out as soon as the internal finishing of the aerated concrete walls is completely dry. In addition to plastering, it can be lining, siding, plastic, artificial stone or facing bricks.

Honing is often used for interior and exterior wall finishing - surface decoration with abrasive substances using honing heads (hones). This is a completely new direction in construction, and before it was used only in the automotive industry and in the repair of engines. But for honing, the blocks must be almost perfectly laid, and the mortar joints must be of the minimum thickness, otherwise it will be necessary to apply a thick layer of plaster and wait until it is completely dry.

The choice of honing finish also includes priming the walls and installing reinforcing mesh with a thickness of ≤ 5 mm. The mesh is attached to the putty, the surface is leveled, a thin layer of plaster is applied on top with a layer of ≤ 5 mm. After 7 days, necessary for the layer to dry, a tinting layer is applied, the color of which is selected upon purchase. If it is required to apply a thick layer of plaster, then this is done in 2-3 steps, and each previous finishing layer must dry completely.

Finishing with plastic, clapboard or siding is faster than plastering or honing - decorative elements are fastened quickly and reliably to a frame mounted from metal profiles. In addition, such decorations will cost the developer less than covering the walls with several layers of plaster.

But quite often, developers do not stop at any one finishing material, but successfully combine several types of finishes. Often, finishing a house of aerated concrete blocks consists in combining artificial stone with brick trim, PVC panels and plaster. Such combinations of different building materials do not affect the thermal conductivity of the house materials or the breathability of walls and ceilings.

Tools and finishes

Combined finishing work with different materials requires the use of appropriate tools:

1. Perforator, level, hammer;
2. Tape measure, grinder, screwdriver, puncher or impact drill;
3. Plumb line and marker colored cord;
4. Metal shears or hacksaw.

Indoors, wall surfaces can be finished with or without a mounted frame. The use of a profile frame makes it possible to use drywall sheets, OSB boards or decorative panels - plastic or MDF. Before installing the frame of SD and UD profiles, a waterproofing layer is first attached to the aerated concrete wall, and a vapor barrier layer is attached on top to protect the walls from moisture saturation and increase their service life. When facing walls with sheets of gypsum board or gypsum plasterboard, it is recommended to assemble the frame from aluminum profiles in order to prevent metal corrosion. Any profiles are fastened to the wall with dowels of the “quick installation” series with control of vertical and horizontal installation. Drywall is attached to the profiles using self-tapping screws with a countersunk head.

GKLV is puttied with ordinary dry mortars - they contain glue additives, so the putty holds firmly and reliably. It is possible to decorate the walls of a house made of aerated concrete, the interior decoration of which is carried out with drywall, with MDF panels attached to bars with a section of 20x20 mm. The bars themselves are attached to the gypsum plasterboard with dowels "quick installation" or on self-tapping screws.

The first bars - ceiling and floor - are leveled by a plumb line, and intermediate bars are mounted between 50-60 cm along a stretched cord. The horizontal position of the bars is checked by a level. A special profile with a groove is attached to the corners of the wall (it is sold complete with panels or separately), into which MDF panels are inserted. The panels are attached to each other with special brackets, and the last panel is inserted into the groove of the corner profile. If the walls are finished without mounting the frame (painting, wallpapering), then the walls are plastered or puttied, and after the layer has dried, they are leveled and sanded.

The primary (rough) leveling of walls made of aerated concrete blocks is done with a conventional cement-sand mortar. To make the solution layer stronger, a fiberglass or metal fine-mesh mesh is pressed into it to a depth of 2-4 mm.

After hardening and drying of the draft (starting) layer, the surface is polished with coarse sanding paper, which is attached to a special fixture with clamps. Finishing, finely dispersed coating, fills in all existing irregularities and scratches. The final touch is sanding with a fine sandpaper. This can be done manually, but it can also be mechanized - use a vibration grinder. Before wallpapering or painting, the walls are covered with a deep penetration primer.

To paint the walls, they take any paint - nitro, enamel, oil, acrylic, since the surfaces are already protected from moisture penetration. The required shades do not have to be found in stores or on the market - they can be obtained by mixing several paints with a construction mixer in a bucket or large container. The amount of paint must be prepared so that it is enough for all surfaces to be painted - taking into account the fact that some places will have to be painted over 2 or 3 times. Paint consumption is indicated on the bank, so the total volume is not difficult to calculate, and a reserve of 10-15% will give you confidence that the paint will not run out at the most inopportune moment.

The paint is applied in several layers, with a roller or a paint brush, you can not wait for the first and other layers to dry. If the paint is sufficiently liquid (this happens with water-based or acrylic paints), then it can be sprayed with a construction spray gun. Layers 1 and 3 are applied vertically, and layers 2 and 4 are applied horizontally. Such a checkerboard approach will allow you to more evenly distribute the color over the surface, and prevent gaps on the wall.

Wallpaper can also be glued to any - vinyl, non-woven, paper, fabric, etc. Instructions for working with wallpaper are indicated on the roll.

Aerated concrete houses interior decoration updated: January 12, 2017 by: Artyom

There are many different methods and materials with which the internal decoration of walls from gas silicate blocks is carried out. The choice of a specific technology is based on maintaining the vapor permeability of the walls. To this end, the finishing of walls made of aerated concrete indoors is carried out using wallpaper, paint or sheets of waterproof drywall. In rooms with high humidity, tiles or plastic panels are used, but in all cases, first of all, all necessary measures are taken to ensure reliable protection against moisture.

Plastering

Unlike the finishing of the exterior walls of aerated concrete houses, the interior decoration of aerated concrete walls can be carried out in accordance with the requirements and features of modern design, which allow the surface to be left without any finishing coating and plaster. However, given that one of the most interesting types of interior decoration today is the application of decorative plaster for concrete, you can finish the room inside using a conventional plaster mixture.

The photo shows that the application of plaster on the surface of walls made of aerated concrete blocks does not differ from ordinary plastering.

When starting work, you must strictly follow the rules and sequence of their implementation:

1. Aerated concrete walls are treated with a primer using a deep penetration composition and applying it in 3-4 layers. Each subsequent one is applied, waiting for the previous one to dry completely.
2. Having completed the priming, they begin to install construction beacons, and in some cases (with high quality masonry) they do without them.
3. Plastering of gas blocks is carried out using a gypsum mixture, distributing it along the wall using special equipment or manually.
4. Excess mortar is removed from the wall with a rule, achieving a smooth and even surface.
5. Having completed the application of the starting (base) mixture, they begin to work with the finishing composition, and only after it has completely dried, you can think about what the interior decoration will be like.

In most cases, the outer walls of the building are insulated, and therefore the plaster mixture can be applied directly to aerated concrete blocks.

The final stage of finishing can be painting the surface, gluing vinyl or non-woven wallpaper, laying tiles or fixing decorative MDF panels. When choosing, you need to take into account the functional features of the room in which the repair is being carried out.

Alignment of walls from gas blocks with sheets of drywall

The interior decoration of aerated concrete walls requires preliminary high-quality insulation and reliable waterproofing, created using materials that do not reduce the vapor permeability of the aerated concrete blocks themselves and allow the house to “breathe”. Aligning the walls with drywall allows you to place the material selected for insulation under the plasterboard, hide the wiring from prying eyes, give the room the desired shape and make its geometry special or even complex.

As shown in the photo, sheathing a wall with plasterboard sheets is quite simple if the frame is correctly installed and all the nuances of the technological process are observed during fastening of solid or cut sheets.

In accordance with the requirements of the technological process, finishing work related to the leveling of aerated concrete walls with the help of gypsum boards begins with the preparation of the surface, on which, as usual, a primer mixture is applied, after which the frame is completely dried, the frame is assembled:

1. The first grandfather needs to make markings on the floor and ceiling around the entire perimeter of the room.
2. The guide profile is fixed with dowels in accordance with the markings, first to the ceiling, and then to the floor.
3. The next step is the installation of rack profiles. They are literally stuck first into the floor guide, and then the second end is carefully inserted into the profile fixed on the ceiling. The distance between such racks should not exceed 60 cm.
4. Next, the insulation is laid and the transverse jumpers are mounted at a distance of 40 cm from each other. Such a crate will securely fix the heat-insulating material, guarantee the strength and reliability of the entire structure.

Having completed the installation of the frame and the laying of thermal insulation, it is possible to sheathe the structure with sheets of drywall. First of all, solid sheets are attached to the profiles with self-tapping screws, and the sheathing is completed with undercuts.

Finishing - painting, wallpapering, tiling. Any option chosen will help change the interior space of the apartment, create coziness and comfort, and the main advantage of this design is the ability to provide effective protection of aerated concrete walls from the negative effects of moisture and extend the life of the building.

Finishing with artificial stone and other types of work

The peculiarity of aerated concrete lies in its high adhesion. Various finishing materials perfectly adhere to its surface:

• artificial and natural stone;
• plaster mixture of sand and cement;
• gypsum plaster.

Before proceeding with fixing the artificial stone, it is necessary to qualitatively prepare the surface of aerated concrete walls and eliminate all detected defects (chips, cracks, cracks). They are sealed with a cement-sand mixture, preparing the surface for leveling.

Before the plastered wall is painted, several layers of putty must be applied to its surface. Starting, base and finishing coatings are created by qualified craftsmen, but you can do all the manipulations yourself with your own hands. To do this, follow the instructions given by the manufacturers exactly. You can find information on the packaging of mixtures intended for puttying.

You can start painting after processing the putty surface with sandpaper and additional priming. The walls are impregnated with a primer twice, and they start painting after the surface has completely dried.

Finishing the aerated concrete walls of the building outside

There are many ways and materials by which the exterior decoration of the walls of a building constructed from aerated concrete blocks is carried out. Each of these methods has its own distinctive features, advantages, features. Most often, brick is used to perform such work.

As you can see in the photo, this design does not have a high level of complexity, but requires compliance with all the rules when performing masonry.

Cladding of aerated concrete walls outside the house is carried out by creating half-brick masonry and single-row dressing of seams. This cladding allows you to increase the level of strength of the entire building and give it an external appeal. In the seams between the bricks, free space is left without completely filling them with mortar. This provides ventilation and allows the house to breathe, preventing the possibility of condensation.

Binding of brickwork to aerated concrete walls is carried out using reinforcing bars made of galvanized steel. Despite the rather significant material costs, this method of finishing the exterior walls of a building erected from aerated concrete blocks is very popular. This is due to the fact that the brick is an environmentally friendly material, and, in addition, the space between the aerated concrete and the facing brick is filled with insulation, which provides additional heat savings and effective protection from the cold.

Being engaged in the design of the facade of a building erected from aerated concrete, it is worth paying attention to such materials as:

• siding;
• decorative plates;
• natural or artificial stone;
• putty.

The building takes on a finished look, becomes resistant to the negative effects of aggressive environments and temperature changes.

Facing with siding or decorative plates involves the installation of a frame, which becomes a high-quality support for fixing not only the finishing elements themselves, but also the insulation plates.

When starting to work on facing with siding or decorative plates, it is necessary to take care not only of high-quality thermal insulation, but also of fixing waterproofing materials.

As a waterproofing, a conventional polyethylene film can be used, which is laid on a layer of insulation, and the gap between the insulation and the walls of gas blocks is maintained for ventilation, which prevents the formation of condensate on the walls and their premature destruction or the appearance of mold and fungus.

This type of finishing of the exterior walls of the building, erected from aerated concrete, is recognized as the highest quality and most effective. With such a cladding, the walls of the house are reliably protected from moisture, but they “breathe” freely.

External finishing can be carried out with the help of high-quality plaster, but carrying out such work requires careful surface preparation and the use of specially created materials.

The video shows how to properly perform plastering work on the internal walls of the house, if they are built from aerated concrete blocks.

Despite the fact that plastering does not require significant material costs, you will have to be prepared for a long process, during which you will need to carry out a thorough, full-fledged surface preparation.

Today, it is difficult for classic building materials to compete with modern technologies, which can be used to 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 the characteristic features of the 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 of 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 of a wall 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 transverse sections on the plastic panels and the lining made of wood 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 must begin with the installation of 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 one must be applied horizontally, etc. When working with water-based paint, you do not need to wait for the layers to dry.

Fake diamond

Now many people prefer this type of finishing material. This is due to the positive characteristics of the 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.

The installation process of artificial stone is quite 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.

When choosing aerated concrete for building a house, owners and builders take into account its advantageous characteristics: thermal protection, easy processing, high vapor permeability. The interior decoration of the house made of aerated concrete allows not only to arrange everything in the desired style, but also to create a comfortable climate in the rooms. To achieve good air circulation and at the same time insulate the interior from steam, you need to choose the right finishing material for aerated concrete blocks.

The main features of aerated concrete

Small pores are clearly visible in these wall blocks - this is cellular concrete, which, due to this structure, receives its main advantages. During the production of aerated concrete blocks, gas-forming substances are added to the solution. The blocks are light, "warm" and durable, if you follow the construction technology.

The light weight of the blocks allows you to save on the foundation for the entire building. Walls made of porous concrete have excellent thermal insulation properties and can reduce the cost of maintaining a comfortable temperature in the premises all year round.

Among the shortcomings of porous and soft aerated concrete, its lower bearing capacity is noted in comparison with brick, while it can dust and crumble during operation. But when installing drywall, when the house is finished with aerated concrete inside, the excessive softness of the base becomes an obvious plus.

It is very easy to build and then finish walls from lightweight aerated concrete silicate blocks. To drill a hole in them, you do not need special tools. However, special anchors will help to hang furniture on an aerated concrete wall or fix equipment, this will not be a problem.

Carrying out interior decoration

When choosing this wall material, its ability to absorb vapors is taken into account. When finishing the walls of aerated concrete inside, apply a uniform layer of plaster of a suitable type. After that, you can glue the wallpaper, paint or apply decorative plaster. Thus, optimal vapor permeability is achieved and the right indoor climate is created.

The choice of plaster for walls

It is worth remembering that some finishing materials can make the wall impenetrable, which will increase the likelihood of condensation forming, which will destroy aerated concrete over time. This figure will be reduced several times, for example, vinyl wallpaper and plastic wrap.

To safely and efficiently complete the interior decoration of a block house, you can use:

• drywall,
• plaster,
• ceramic tiles,
• some other finishing materials.

Keeping the vapor barrier will help finish the walls of the gas block with sand-cement plaster or gypsum plaster mixture of perlite sand, slaked lime and alabaster. The consumption of gypsum mixture is approximately 9-10 kg per 1 m 2, and cement - about 12.5-19 kg for the same area and thickness of 1 cm.

In our country, Rotband gypsum plaster is quite popular - at a price of 1.5 times higher than the usual mixture, it has a lower consumption, which equalizes the costs of these finishing materials with the obvious advantages of the first.

Solution preparation

An important step in the finishing process is the preparation of a quality solution. We recommend that you follow the manufacturer's instructions for each of the materials, as even instructions on the Internet may not always correspond to the requirements of the factory.

It is necessary to achieve that:

• the mixture adheres strongly to the surface,
• the consistency of the solution turned out to be optimal,
• the freshly prepared mixture was immediately used.

Preparation of gypsum plaster mortar

Plaster prepared for interior work should not be used for processing exterior walls. The wall is covered several times with a primer, drying each new layer. The vapor permeability of the surface due to this treatment is greatly reduced. Gypsum plaster is applied to the primer, and then the selected material is finished.

Step by step wall decoration

The working surface is cleaned of glue and old coating. The resulting potholes are leveled and filled with mortar, reaching a flat surface of the wall.

The first and subsequent layers of primer are applied to the entire wall. It is allowed to be used both in industrial and residential premises. Beacons from a long profile are fixed in parallel and vertically, and then their even installation is checked.

Applying plaster with beacons set in advance

The plaster "fur coat" is applied with a layer of 1 cm, which allows you to hide all the irregularities. Plastering the surface of the wall, it is leveled with a spatula when dry. After the process is completed, the beacons are removed, and the holes from them are sealed with a solution.
