How to sheathe an aerated concrete house outside. Interior decoration of a house made of gas silicate blocks: materials and examples of their use. Method of work

Aerated concrete blocks, due to their high thermal insulation characteristics, are very popular today in private housing construction. But they have one drawback - high water absorption. Therefore, a precisely selected and obligatory exterior decoration of aerated concrete house is the main requirement for the design of the facade. Needless to say, manufacturers today offer a huge amount of various materials, which are used to decorate the outside of the house. All of them can be used when decorating the facade of a house made of aerated concrete blocks.

Types of materials for facade finishing

Before proceeding to the analysis of the finish, it is necessary to indicate that aerated concrete is a type of light cellular concrete with a high vapor permeability index. That is, the walls assembled from this material "breathe" well. It is with this indicator that it is necessary to carry out finishing work.

Plaster

This is the easiest finishing process at first glance. But he has several points to consider:

1. Traditional cement plasters are not suitable for finishing aerated concrete. The latter from the solution will instantly absorb moisture due to the high rate of moisture absorption. Therefore, the applied plaster layer will crack or peel off altogether. No primer will help here.
2. For the finishing of facades from aerated concrete blocks, special plaster mixtures have been developed based on additives that prevent moisture absorption. Manufacturers write on their packages - for aerated concrete blocks.
3. External wall decoration from the outside is associated with the preparation of the trimmed plane. Aerated concrete is being prepared as well. Only for this, special primers for aerated concrete are used.

Himself technological process plastering standard. It includes the installation and fixing of the plaster mesh. You cannot do without this element, because aerated concrete blocks have a very smooth and even surface, so that its adhesion to the plaster solution will be minimal. The mesh enhances grip. Beacons must be installed in the form of metal profiles, between which plaster mortar is applied.

As for the finish, in terms of using plaster, you can approach the issue from different positions. For example, paint with facade paints, or use decorative plaster, which contains mineral additives in the form of stone granules, glass beads and others decorative materials... Today, the popular wall decoration outside is bark beetle.

Brick cladding

Facing a brick house made of aerated concrete is another traditional way to protect porous material. Here are the advantages of this option:

• brick is a durable material with good sound and heat insulation characteristics;
• it has a high bearing capacity;
• appearance - presentable;
• easily withstands the negative effects of precipitation, sun rays and the wind.

But the cladding process itself is not so simple compared to plaster. This requires experience and qualifications. And if you are assured that the brick cladding process can be done with your own hands - do not believe it. After all, laying is not only about laying a brick beautifully, it is necessary to achieve flexible connections for facing bricks and aerated concrete. And this requires experience.

It should be noted that brick cladding is a huge opportunity in the decorative design of the facade of a house made of aerated concrete blocks. And each of them will be unique. To the disadvantages of this type of finish, you can additionally add - a high price compared to plaster.

If there is a need to increase the thermal insulation properties of the aerated concrete structure, you can use the technology of facing brick houses made of aerated concrete with insulation. This technology does not shine with variety. Usually, a heat-insulating material is added to the masonry mortar - perlite or vermiculite, rarely expanded polystyrene chips.

Attention! It is possible to use bricks for facing buildings made of aerated concrete blocks only in private housing construction with a height of no more than two floors. In this case, the use of plaster mesh is a prerequisite.

About the plaster mesh must be said separately. This reinforcing belt must be installed on the walls if their finish is associated with wet technologies.

Clinker and porcelain tiles

Both materials differ from each other strikingly not only in performance, but also in appearance and in price. But the technology for laying them on the walls is the same. Which is the best cladding of the two, it's hard to say. It all depends on the taste of the owner of the house. It should just be noted that the clinker tile has a small amount of decorative design... In this regard, porcelain stoneware is presented on the market in a huge variety.

The very technology of facing a house made of aerated concrete with clinker tiles or porcelain stoneware does not differ from each other. It is simpler than brick, cheaper. Both tiles are thin and lightweight, which reduces stress on the foundation. They have higher strength characteristics than bricks. Easily resist natural stress.

If we talk directly about laying clinker tiles on aerated concrete (and porcelain stoneware, respectively), then, as already mentioned above, a mesh (preferably synthetic) is first installed on the wall, which is fixed in the aerated concrete wall with self-tapping screws or nails. Fortunately, concrete allows this to be done without drilling mounting holes. As a masonry mortar, a special mixture is used, designed specifically for aerated concrete surfaces.

But there is one difference between the two tiles. The clinker has small sizeso it is difficult to work with it. Porcelain stoneware has large dimensions, so its installation on the wall is a more simplified process. Today the technology of wall cladding with dry-type porcelain stoneware is presented on the market. This is when the tiles are laid on the crate. This option is much easier when it comes to doing it yourself.

By the way, when the task is to insulate and clad the facade with porcelain stoneware, then this technology - optimal solution... In this case, the tile does not fit onto aerated concrete. An air gap remains between it and the walls, which can be filled with thermal insulation material. This technology is not only easier to implement, it allows you to repair cladding without disassembling a large amount of cladding material.

Clinker tiles on aerated concrete are laid only using wet technology.

Siding

We turn to the finishing of the facade aerated block using dry technologies. A bright representative this category finishing materials is siding: plastic, metal, ceramic, cement and wood. When the question is raised, how to decorate an aerated concrete house with your own hands without complex construction operations, then it is the cladding of the building with siding that is.

Each variety of this finishing material has its own pros and cons. For example, metal, cement and ceramic are one hundred percent fire safety. Vinyl siding - this is a huge variety of decorative design. Wooden is the natural beauty of the wood structure. Although today new technologies make it possible to design all types of siding for almost any natural materials.

A separate group is thermal panels made as a decorative heat-insulating material. The outer layer is a tile: clinker or stone, the back layer is insulation, and between them there is a base in the form of an OSB board.

It should be noted that all of the above materials refer to a large group of ventilated facades. That is, these are exterior finishes that are not attached to the wall being finished. For this, a frame is assembled from a metal profile or wooden slats, on which the panels are attached. A gap remains between the finish and the aerated concrete wall, which in this case performs the functions of ventilation. Coming out through the blocks out indoor spaces warm and humid air is immediately removed through the gap outside the finishing structure. It turns out that moisture will not condense on aerated concrete walls, which means that they will last a long time.

How is the installation of a ventilated facade carried out correctly?

1. The frame is assembled in the form of vertically installed profiles, the distance between which is determined by the length of the siding. For example, for a standard metal material, the length is 3 m.This means that the installation of the frame elements is carried out either after 0.5 m, or after 0.6 m.
2. Be sure to install profiles along the perimeter of window and door openings.
3. If the sheathing of aerated concrete is carried out with insulation, then after assembling the frame structure, it is necessary to lay down the heat-insulating material. Depending on the selected type of the latter, additional tasks are solved regarding the protection of the insulation. This mainly concerns mineral wool, which must be covered with a waterproofing film on the back and a vapor barrier on the front.

Attention! Since a ventilated facade is being assembled, a gap must be left between the insulation and the surface of the aerated concrete wall.

The process of installing siding itself is no different. For this, mounting holes are made in the material at the factory, through which fastening to the frame is carried out. The main thing is to install the panels exactly horizontally. Panels of all types of siding are connected with a tongue-and-groove lock. This is not only a strong bond, but also an invisible seam, plus ease of installation.

Lining

This wood cladding material can be categorized as siding. Although in the register of building materials, it appears as a separate group. What can be said about aerated concrete lining. There are no restrictions on its use for facing an aerated concrete house. This material belongs to the technology of ventilated facades. Therefore, they mount it on frame crate, like other types of siding.

But there are some requirements for it:

• mandatory treatment with an antiseptic and anti-feather composition;
• selection of dry lumber for both the frame and cladding;
• external protective painting or varnishing against the negative effects of atmospheric precipitation;
• it is optimal if the roof of the house is made of aerated concrete with a large cornice, which itself will cover the walls sheathed with clapboard.

With wet technologies, everything is clear, they require special adhesives. But it must be warned that aerated concrete is not as strong as concrete or brick. Therefore, for the installation of ventilated facades, it is necessary to use special dowels as fasteners, which are specially made for aerated concrete.

They are made of plastic (PE, PP or nylon) or metal (galvanized or stainless steel). According to the method of installation, the dowels are divided into driven in and screwed in. The latter are considered more reliable and are divided into straight and tapered. A separate group is chemical anchors, which are liquid polymer compositions poured into prepared mounting holes in aerated concrete, where they are polymerized.

A house made of an aerated block without finishing looks quite presentable if you use adhesives for laying blocks. The seam between them is small - up to 2 mm, so the appearance looks like a monolithic one. But the gas block with lining will last longer.

The cheaper the finish, the lower its service life. In this regard, brick, clinker and porcelain stoneware - best materials for finishing the facade of aerated concrete house.

It is better to decorate the aerated concrete bath with clapboard or siding. A large amount of humid and warm air will seep through the walls, so for this building the best option - ventilated facade.

When cladding a house with your own hands, consider the installation technology of the selected material. Strictly follow the rules and requirements of the manufacturers.

When deciding how to sheathe a structure of gas blocks, take into account all the pros and cons of the selected material. Price will not be the last selection criterion.

Outdoor decoration Aerated concrete houses are carried out after all the work related to the interior decoration of the building has been completed. The technical characteristics of the materials used in this case should be the defining moment in their selection. Finishing options for the facade of a house made of aerated concrete blocks can be completely different.

Properties of finishing materials for facades

Aerated concrete blocks have a sufficiently low compressive strength, so they should not be subjected to mechanical stress or shock during transportation. Another disadvantage of these products is their high hygroscopicity or water absorption. Walls made of gas blocks outside and inside must be clad with high-quality finishing material. It must have the following important properties:

1. Light weight.
2. Easy to install.
3. Convenience during transportation.

When choosing the best way to tile a house from aerated blocks, you should not purchase too heavy finishing materials. They require the arrangement of a massive foundation for an aerated concrete house. Since all external work will be done by hand, then during the cladding process there should be no need to use different types technology.

Aerated concrete wall decoration should be carried out using materials that can withstand the effects of various external factors. This will not only allow you to decorate the landscape design of the site, but also make the building durable. Before finishing the house from aerated concrete outside, you should decide on the choice of the most suitable type materials mounting technology. They must have the appropriate functions:

• provide thermal insulation;
• protect the supporting structures of the house from moisture and wind;
• increase the sound insulation of the building;
• ensure the hygiene of the home;
• not be exposed to the negative effects of fungus, mold;
• have a high indicator of water resistance;
• differ in frost resistance.

By finishing the exterior walls of aerated concrete buildings, one can conclude about the tastes and preferences of the building owners. If a vacation home has a well-groomed facade, then the status of its owner is appropriate. Before revealing external walls made of aerated concrete with any finishing material, it should be remembered that it should not be cheap. Otherwise, the service life of the building will decrease due to poor quality cladding.

You can select options for finishing the facade of a house made of aerated concrete after all internal work... They involve pouring the floor screed, laying tiles or plastering. These types of work often cause the accumulation of vapors in the room, so they can freely escape through the thickness of the walls of aerated concrete.

Disadvantages of walls made of aerated blocks

Finishing the facade of a house made of aerated concrete requires the use of moisture-resistant materials for wall cladding outside. This is due to the high moisture absorption of the gas block. It exceeds that of other building materials.

Being a kind of aerated concrete, lightweight aerated concrete has open pores. At the same time, it has high thermal insulation properties. The material exhibits good hygroscopicity in direct contact with a moisture source. As a result, its weight increases and its strength decreases. Subsequent freezing leads to the destruction of the wet block.

During the masonry process, the material also absorbs moisture from the cement composition. As a result, the elasticity of the solution decreases, with the help of which the material is laid. Therefore, aerated concrete finishing is required not only outside the house, but also inside.

Aluminum powder is used as a gas-forming substance in the manufacture of aerated concrete blocks. It is she who provides the porosity of the structure of the material being produced. Due to the high rate of vapor permeability, aerated concrete facade decoration requires a constructive approach. It should be performed in accordance with all requirements.

If the facing work was not carried out according to the rules, then the exterior decoration may be performed with errors. All the nuances should be taken into account even at the design stage of building a house from aerated concrete blocks with cladding. When performing technological operations, you must always take into account the sequence of their implementation.

Line up safe house from gas blocks is possible only if high quality material is used. Preparation of mortar for masonry also requires a careful approach. All heat engineering calculations must be accurate, which will allow you to choose the right material for decorating the walls of aerated concrete blocks outside.

Materials for decorating the walls of the house outside

Decorating the exterior walls of a house made of aerated concrete involves not only cladding, but also the arrangement of thermal insulation. It is best to insulate aerated concrete walls using mineral wool. The layer of thermal insulation will largely prevent moisture from draining from the surface of the outer walls.

The insulation outside the house should be fixed using a wooden crate impregnated with an antiseptic. Perfect option for this task is an iron profile. Self-tapping screws or dowels are used to fasten the outer frame to the wall surface. The insulation should be laid after the installation of the battens.

Common finishing materials are:

• tile;
• siding;
• fibrolite;
• lining;
• clinker brick.

The latest finishing material is available on the market in a wide variety. It differs according to the following criteria:

• texture;
• the form;
• sizes;
• colors.

Before finishing the facade of a house from aerated concrete using clinker bricks, it is necessary to take into account the distance of 3-4 cm from the thermal insulation layer. Vinyl siding is widely used in the finishing materials market.

Clinker tiles for aerated concrete walls

A house made of aerated concrete from the outside can be tiled with clinker tiles, specifications which boil down to the following properties of this material:

1. High thermal conductivity.
2. Long service life.
3. Chemical neutrality.
4. Ecological cleanliness.
5. Reliability and durability.
6. High density index.
7. Fire resistance.
8. Frost resistance.
9. UV resistant.

It is not difficult to beautifully decorate the outer walls of houses, gazebos or verandas made of aerated concrete with tiles. Having developed design idea, you can think about which type of clinker tiles to choose. Since she is characterized by high density, then the thermal conductivity of this material is quite high.

Facing of aerated concrete with clinker tiles can be carried out with or without insulation. If the thickness of the outer walls is normal, then thermal insulation is not required. Any finishing material that does not require additional thermal insulation is laid close to the surface of the outer walls.

If expanded polystyrene is used as a heater, then a vapor barrier membrane is fixed on it. It protects the outer wall from condensation and moisture. It is necessary to lay the elements of the bundle of the facing layer when erecting walls from aerated concrete or after it.

Clinker brick for aerated concrete walls

Choosing how to tile a house from aerated concrete blocks, you can focus on clinker bricks. Before buying, you need to find out the density of the material. If its surface is smooth without any interlayers or voids, then its firing was uniform. The higher the density of the clinker, the higher should be the tone emitted by the brick when it is tapped with a hammer.

The clinker can have a different structure. The need for thermal insulation of the building depends on it. If for facing the outer walls made of aerated concrete blocks, use facing clinker bricks, and not front ones, will significantly increase the service life of the building. At the same time, the cost of repairing the exterior walls of the house will decrease.

Aerated concrete wall cladding with clinker bricks is an environmentally friendly coating. It is not capable of contamination, which is especially important for buildings located in conditions in which there is an increased content of harmful substances. Facing clinker is often used for the reconstruction of worn out facades.

Clinker bricks go well with other types of finishing materials. It can have not only red colors, but also yellow, black, white. Such material looks spectacular, decorating the facades of buildings built from aerated concrete blocks.

Exterior finishing of gas blocks by plastering

At the present stage of the construction of aerated concrete buildings, plastering of houses from aerated concrete is common. In this case, the finishing takes place in stages:

1. The walls are insulated with extruded polystyrene foam or foam.
2. For fastening the heat-insulating material, glue, dowels with caps, self-tapping screws are used.
3. A reinforcing fiberglass mesh is attached to the prepared heat-insulating layer, which makes it possible to strengthen the adhesion of the insulation and the finishing layer.

High-quality thermal insulation not only provides protection against noise, but also allows you to neutralize the effect of atmospheric humidity on the surface of the walls. Since plastering the facade requires the installation of a reinforcing mesh, it is better to choose safe materials. They must be chemically neutral so that the house cladding made of aerated concrete could not adversely affect the mesh up to the formation of rust.

Before finishing the surface outer wall, you must use a special primer. Only then can you go to finishing plaster. It must be of high quality and contain antiseptic additives. The final stage of plastering involves applying facade paint to the surface of the walls.

Natural stone for exterior walls

Facade cladding can be supplemented if the house is plastered from the outside. For this is used decorative rock, which fits in separate fragments. For example, we cover only corners, window openings or a base with it, and the main part remains plastered.

You can use natural stone as a separate facade material... It is laid on a cement mortar, and all joints are filled with grout, which is then leveled. This type of finishing is labor intensive and therefore expensive. A facade made of aerated concrete blocks faced in this way will have a long service life.

Not every home owner has the opportunity to use natural stone for exterior walls. You can solve the problem if you use an imitation of natural material. It also has a rich appearance, which makes it impossible to distinguish it from a natural sample. This will reduce the cost of facing the facade of the house.

A budget option is to use clinker tiles. It is an imitation of clinker bricks. For the manufacture of these materials, components of natural origin are used that have different colors and textures.

Artificial stone for aerated concrete

To cheaply sheathe a house with your own hands, you can use an artificial stone to decorate the facade. The choice of this material is rational. It does not weigh as much as natural stone, which is difficult to fix to the wall surface.

Artificial material has many positive qualitieswhich are also typical for natural stone... Its cost, unlike other types of facing materials, is the lowest. It has a weight that is 1.5 times less than a natural sample.

There are several different ways, allowing you to finish aerated concrete with artificial or natural stone. Due to its minimal weight, the artificial material makes the cladding much lighter. Experienced master sheathes with such a stone not only the internal, but also the external walls of the house made of aerated concrete.

Artificial stone has a wide range of uses. With its help, wall cladding is made of gypsum board or thermal panels. The material is used not only the same shape, but also combined with analogs of other colors and parameters.

To perform the facing of the facade with artificial stone, you do not need to exert much effort, since it has a flat surface on the back side. Corner elements, which allow finishing of window and door openings, are used for finishing corners. Facing the facades of buildings with artificial stone is a bit like a surface finished with clinker tiles.

Aerated concrete is a porous stone made of cement and quartz sand, a type of aerated concrete. It is widely used in the construction of private houses due to the speed of construction, good thermal insulation properties, and low prices. Unfortunately, it has a high moisture capacity. Many open pores in the stone that keep it warm building material, when in contact with water, are easily filled with it. When aerated concrete blocks are saturated with moisture, thermal conductivity increases. Therefore, the external decoration of the walls of such houses should have, along with a beautiful appearance, strength and moisture resistance.

It must meet the following requirements:

• reliably protect the outside of the house wall from moisture, rain, snow;
• do not change their properties in the cold;
• be resistant to chemical environments, vehicle exhaust gases;
• do not fade under the influence of sunlight;
• resist ignition;
• have high heat-insulating, soundproof characteristics.

The most common options for exterior decoration of the facade of houses:

• plaster;
• siding finishing;
• facing with brick or stone;
• painting.

Plaster with ordinary sand-cement mortar is not suitable for walls made of aerated concrete blocks due to its moisture permeability.
If it is decided to plaster without insulation, then aerated concrete blocks must be covered with a penetrating primer. All subsequent work should be done after it dries. Plastering the facade of a house from aerated concrete blocks should be performed using a reinforcing mesh. Especially critical places: house corners, window and door slopes. Then putty and painting is done.
Modern thin-layer facade plaster mixes effectively replace the plaster with a reinforcing mesh. The selected plaster mix should:

• be easy to use;
• lie well on the base, be evenly distributed;
• have good adhesion;
• have a long shelf life.

Facade mixtures are:
Mineral decorative facade plasters are made on a cement basis. To increase adhesion, redispersible polymer powders are introduced into the mixture. Sometimes these mixes are sold as polymer-cement mixes. They are packaged in bags.

Before use, the powder is diluted with water according to the instructions. They are used on concrete, brick bases, on basic plaster. Before applying such mineral plaster, the base must be primed and the primer must dry. This plaster is moisture resistant, nonflammable, durable, inexpensive, when applied with a water repellent composition, it lasts up to 20 years. TO negative properties include the hardness of the coating and the difficulty of obtaining the desired color.
Acrylic based exterior wall plaster is synthetic. Sold in liquid, ready to use. Such plasters have high moisture resistance, resistance to deformation, good adhesion to the base. But low vapor permeability forces you to carefully approach the choice of insulation. For example, mineral wool can get wet. Another serious disadvantage is flammability.
Silicate facade plasters are made with a predominant predominance of potash water glass.

Such plasters are sold in liquid form. Their indisputable advantages: strength, elasticity, hydrophobicity, vapor permeability, antistatic properties. The disadvantages are limited colors and fast adhesion. After breaking the integrity of the package, all contents should be quickly used. Before plastering the walls, they should be covered with a special silicate primer.
Silicone or silicone plasters for the facade are made with a predominance of silicone, which gives them moisture resistance, good adhesion, elasticity, ease of use. The only drawback is the high cost.

Siding is a modern type of protection for the facade of a house

Siding is the most reliable protection walls of the house from adverse weather conditions. The house is sheathed with clapboard, vinyl siding, metal profile sheets or ceramic panels. A crate is attached to the house, on which siding panels are reinforced. The facade is well ventilated.

If a layer of insulation is laid between the siding and the wall of a building made of gas blocks, there is an additional opportunity to reduce heating costs. This is often the best way to protect the façade.
Wood siding - This is the external facing of the walls of the house with specially processed boards. In cold weather, it keeps warm well, creating a cozy atmosphere in the house. Such a house has a representative stylish look. In modern construction, the following types of house wall decoration with wooden siding are popular: house block and false timber. A block house is a board with a semicircular shape on the front side, imitating planed logs. The front side of the false timber is flat. The outer trim with raised timber imitates timber walls. Facing boards are treated with compounds to increase strength, against fungus, wood borers, moisture. Wooden siding from natural wood much more expensive than other types of siding, but this is offset by environmental friendliness, low thermal conductivity, presentable appearance.

Facade cladding from the outside with wood siding or glued clapboard made of wood-polymer composites is cheaper. It is made by pressing under pressure at high temperature of wood fibers and polypropylene. Such siding is resistant to moisture and fire, does not require coating with paints, impregnation with protective substances, and serves for more than 15 years.
Vinyl siding is made on the basis of polyvinyl chloride with the addition of modifiers, stabilizers, dyes and other components that improve the operational and aesthetic properties of the finishing material. Looks like regular board, but without additional processing retains its properties and appearance for at least 20 years. It is very practical in operation: it does not require complicated maintenance, it withstands temperature changes well, it is resistant to dirt, it is easy to install. Vinyl siding also comes with imitation of stone, brick.
Metal siding is profiled metal panels made of galvanized sheet steel with a polymer coating. The coating imitates a ship board, timber, lining, etc. The structure of steel siding consists of several layers.

A passivating layer against corrosion is applied to the galvanized sheet on both sides, then primed. After that, a polymer layer or paint is applied on the front side, and a layer of protective paint on the inside. The panels are made with a thickness of about 0.5 mm. Metal siding outperforms other types of siding in durability (service life up to 50 years), fire resistance, strength, low cost. The disadvantage is the greater weight, which increases the load on the supporting structures of the house and the foundation.
Cement siding is rarely used for wall decoration because of its disadvantages. Such panels are made of sand and cement. They are heavy, require very solid lathing and load-bearing structures... Silicon dust generated during sawing also causes difficulties in installation. The main advantage is incombustibility. It is better to use it where there are increased fire safety requirements.

For facing aerated concrete blocks with a brick or finishing stone, it is necessary to provide for the width of the foundation for the house, taking into account the thickness of the facing layer, so that the main bearing wall and the facing layer can stand on the foundation.

A gap of 30-50 mm should be provided between the wall and the facing layer, and a layer of heat-insulating material is also possible for insulation. Without a gap, you can decorate houses in which you plan to live only in the warm season. Brickwork must be firmly connected to the wall of aerated concrete blocks and be a single solid system. This solidity is achieved by establishing connections. They are brought into the facing and supporting structures during masonry. They are metal and basalt-plastic.
The facade of the house can be faced with natural or artificial stone. Natural stone has a respectable appearance, eco-friendly, durable, durable, non-combustible, easy and quick to fit. The disadvantage is the large weight of the stone, which increases the margin of safety of the foundation and supporting structures of the house. The construction industry offers natural stone slabs. They are laid on the frost-resistant glue "For stone". The back side of the plate must first be primed. After finishing the facing work, the stone surface must be covered with water-repellent compounds, for example, "Hydrophobe".

Much cheaper and weighs less fake diamond... Easy styling standard sizes and the same characteristics of the facing boards. On sale there is a wide variety of facing stone, a wide range of colors.

Coating with special paints and putties

Coating of aerated concrete blocks with special paints and vapor-permeable putties is the most cheap way protecting the facade of the house from moisture. They are sold as dry mixes. The most popular putty of this class is "Prospectors". Before use, they are diluted with water and color is added to give the paint the desired color. The finished paint is applied with a roller or brush in two layers. The main disadvantage of this method is the need for careful preparation of the base surface. This is the cheapest way to decorate the facade of aerated concrete blocks, but also the most short-lived.
If additional wall insulation is required from the outside, the simplest is foam insulation, then putty with a reinforcing mesh and painting. The foam is attached to the base with glue and dowels. It is better to seal the joints between the foam panels with tile adhesive. Then the entire surface is reinforced with a fiberglass mesh, putty with any putty for outdoor use, and painted.

For a long time, the outer walls of houses were faced with finishing materials. The decorative cladding made the buildings unique, protected from adverse influences, and increased the service life. The modern construction industry offers different options materials for finishing the facade of houses from aerated concrete blocks. The choice is best made based on the financial capabilities of the owner, aesthetic preferences, and durability. The final look of the house should be in harmony with the interior, and landscape design personal plot and the surrounding nature.

In the construction of private houses in recent years, they are increasingly using This circumstance cannot be called accidental. The mentioned material has a porous structure, which is characterized by high thermal insulation qualities.

Aerated concrete absorbs a lot of moisture and dust, as a result of which it oxidizes, becomes heavy, darkens and loses its quality advantages. In order to avoid this, the exterior of the house is made of aerated concrete. This makes the facade resistant to external environmental influences.

Exterior finishing options for aerated concrete

Before performing work on finishing aerated concrete outside, you must familiarize yourself with the basic technologies. The most economical method is plastering. It is important to choose the right composition, preferring a vapor-permeable viscous mixture. In order to achieve a higher strength of the layer, you should additionally use a reinforced mesh, this is especially true for difficult places, namely:

• profiles;
• windows;
• corners.

Exterior decoration of aerated concrete house can be done with bricks. For this, the foundation should be made stronger. Its width should include brick and block. For the reason that the brick passes less steam than aerated concrete, an opening is formed between the materials. Its width should be 50 mm. This approach will eliminate the accumulation of condensate inside the structure. Ventilation is provided by the empty joints between the bricks, which are left at the top of the walls. The total area of \u200b\u200bthese joints should be 1% of the total area of \u200b\u200bthe building.

If they have a low vapor permeability coefficient, then the formation of air gaps can be abandoned, but this approach cannot be called the best, because this will increase the thermal conductivity of the walls and lead to cooling of the premises. Heating costs will be more impressive. Summer cottages or houses can be lined without the formation of gaps.

When cladding, a sheet should be used that will resist the contact of the blocks with the mortar. The canvas shifts as the masonry progresses. The cladding cannot be installed without supports. For example, a brick is connected to blocks, which will allow you to get a monolithic structure. This indicates that four ties should be laid across each square meter. They should be foreseen in advance. For this, metal tapes, basalt plastic ties, perforated strip made of galvanized steel are usually used. Elements are inserted into blocks, while the other side is inserted into bricks.

Use of paint

Exterior decoration of aerated concrete house can be done with paint. It will cost less than other solutions. It is necessary to use for this special composition or putty, which must be vapor permeable. This will protect the blocks.

The paint is diluted with water before application. The disadvantage of such a cladding is a rather long preparation time for the external walls. All seams and irregularities must be cleaned, as well as dents and protrusions. Aerated concrete blocks can be prepared by cutting a chamfer around the perimeter. This will ensure smoothness and evenness.

Alternative solution: siding trim

Siding is another popular facing material for aerated concrete. It can be executed based on different materials... It:

• wood;
• metal;
• vinyl.

This helps to protect the facade from climatic influences. The advantage of this approach is the ability to additionally insulate the walls by laying insulation under the siding crate. The frame, by the way, will play the main role in the cladding, because it is on it that the panels will be installed, the gaps between which will provide ventilation of the structure.

You can carry out the exterior decoration of the house from aerated concrete with fiber cement panels. Fastening can be carried out directly to the wall with self-tapping screws. An alternative solution is to install the frame. In both cases, clamps are used for installation, through which the fasteners are screwed into the lathing elements or the wall.

Fiber cement elements are fixed to each rack. The distance between the fasteners should be 600 mm horizontally. Cleamers are installed more often in areas adjacent to door and window openingsas well as in the corners of the building. Such an external decoration of the walls of a house made of aerated concrete sometimes provides for the formation of an air gap, which in some cases is used to install insulation material.

Technology features

Experts do not recommend fixing panels to a frame or a wall without clamps, but in some cases this approach is the only correct one. This is useful if panels require fixation in areas where brackets cannot be installed. In this case, the products are drilled through, and then self-tapping screws are screwed into the holes, the head of which is recessed inward by 1.5 mm. After finishing the lining, the holes are covered with plaster with moisture-resistant characteristics. For this purpose, you can use a paste-sealant, which is selected by color, and sometimes comes in the kit.

Before starting work, you can consider a photo of the exterior of a house made of aerated concrete. If the technology is used as a cladding material, the technology will be slightly different. The elements are installed at an angle, they are located with an overlap of the upper boards on the lower ones. This allows you to get the effect of a shipboard or Christmas tree.

The siding will be located exclusively on the top side of the panel and will be attached to each of the frame posts. When joining the boards in length, a gap of 2 mm should be left between them to compensate for linear thermal expansion when exposed to temperature. The caps of the self-tapping screws will be overlapped by the boards fixed above. Plates can be installed to the wall in a frame manner. This involves the use of metal frames, in the grooves of which the fiber cement panels are installed. In this case, the surface of the slabs and the strips of the frames will be visible.

About frame

If the exterior decoration of a house made of aerated concrete is carried out with the help of then the crate can be made of wood or galvanized metal profile. Horizontal timber elements must have a cross section within 50x30 mm. The distance between them on the wall will be 600 mm. Anchors are used to secure them. The vertical frame racks are usually 40x70 mm in size. They are fastened with two self-tapping screws. The step between vertical bars is also usually 600 mm. These parameters should also be adhered to for the reason that thermal insulation is usually produced with such dimensions. This indicates that it will be easier to install and less waste.

Method of work

In some cases, facing with fiber cement slabs and boards is carried out from the blind area to the abutment to the cornice. The base does not stand out in this case. Otherwise, a zigzag-type frame should be formed, the lower part of which will be filled with expanded clay of the middle fraction. This material acts as an excellent insulation and will protect against rodents.

In order to eliminate the need for plastering the walls, the gap is filled with cement mortar, which is pre-mixed with expanded polystyrene chips or polyurethane foam. The filling should be carried out sequentially, which will occur as the finishing panels are fixed. If the exterior of the house from aerated concrete is finished with fiber cement elements, then whatever method of installation is chosen, you should start from the bottom of the wall. You can move from the blind area, which is true if you plan to veneer the base with this material.

When cutting slabs, the cuts should be painted with an acrylic compound, which is often supplied in the kit. The paint will mask the cut and will protect the end part from moisture and other factors. After completing the installation of panels on the basement part of the wall and above it, it is necessary to install a metal sill. The easiest to install is the one that is attached to the wall.

Opening perimeter finishing

Having considered the options for finishing houses from aerated concrete, you can choose which should also be installed around the windows. In order to cope with this work as accurately as possible, you should use dividing strips. The gaps are closed with a special decorative corner, which will ennoble the appearance. If wide slopes have formed around the window, then they can be decorated with the same panels so that the joint is neat. For this, a starting profile is fixed to the box, and plates are installed in its grooves. The gaps before installing the plates in them are coated with a sealant.

Facade plastering

A house made of aerated concrete for finishing should be prepared with a brush. Chips and dents are sealed with glue, which is pre-mixed with aerated concrete dust. The minimum layer thickness is 10 mm; the material does not need to be reinforced. The composition contains cool additives, thanks to which the mixture will be kept on the surface as firmly as possible. If the layer thickness increases to 15 mm, then it can be reinforced with a fiberglass mesh. A more impressively thick house decoration made of aerated concrete is impractical.

When choosing a mesh, you should prefer one with a mesh of approximately 3 mm. The material must be resistant to alkaline media. Otherwise, after a while, the mesh will lose its strength and cease to hold the plaster, and the finishing layer will simply come off. First, a primer mixture is applied, after which reinforcement is carried out. This will create a base for decorative plaster.

Reinforcement

The composition is applied in a strip. Until the solution hardens, a mesh should be laid on it by pressing it in with a float or notched trowel. Once the mesh is submerged, use a wide trowel to level it. Surface on final stage left until dry. This period may vary over time depending on the material used. Finishing a house made of aerated concrete at the next stage involves applying a primer that paints over grey colour and reduces porosity. After the primer has dried, you can proceed to applying decorative plaster.

Quite often, consumers wonder what is the best exterior decoration of aerated concrete house. Among other solutions, one should highlight the tiles, which can be ceramic or clinker. Its surface is able to withstand the effects of aggressive substances and precipitation. The weight of such cladding is lower compared to brick, which reduces the load on the foundation. The dimensions of the tiles are small. This indicates that continuous cladding will be labor intensive.

Sometimes clinker is used to decorate façade fragments. In this case, the tiles are combined with plaster. Exterior decoration of aerated concrete house can also be performed using thermal panels, which are usually used with an impressive facade area. This allows for decoration and insulation. The front side of such panels in a factory is complemented by stone or clinker tiles. In this case, it is natural.

Conclusion

For aerated concrete walls, one of the many materials that are on the market today can be used as a decoration. Among others, one should highlight porcelain stoneware, which has more impressive dimensions in comparison with clinker tiles. This simplifies the work of a continuous facade cladding. You can fix porcelain stoneware on wooden crate or glue. In the first case, it will be possible to ensure good ventilation of the facade.

Porcelain stoneware tiles, if necessary, wall insulation can be installed on an aluminum profile. The facade will have to be prepared very carefully. The surface must be protected, the seams repaired and the potholes filled with polyurethane foam.

The use of aerated concrete blocks has become quite popular in our country. The reasons for this boom are the affordable cost of the material and the ease of its installation. With the help of aerated concrete, the construction of cottages is carried out very quickly, since the dimensions of the material allow you to quickly build load-bearing and internal walls.

Another indisputable advantage is the lightness of the aerated concrete block compared to classic brick or other types of cement-concrete structures. For a house from such blocks, it is not necessary to create a particularly strong foundation and carry out excessive reinforcement. This affects the cost of building a house and the final estimate.

Among all its advantages, aerated concrete material has one significant drawback - it is porous and quickly absorbs moisture. The creation of internal cavities with air provides high performance thermal protection, but contributes to a high level of vapor absorption. Aerated concrete house cannot be used without external cladding. This will be discussed in our article.

How to wall a house made of aerated concrete?

Without exception, all professionals in the field of construction will point out the need for high-quality exterior wall decoration of the built cottage. If someone says that it is enough to paint the surface - immediately chase such a "master", as he does not understand the essence of the issue at all. Finished projects of houses and cottages from aerated concrete initially have a separate estimate for facing work. The architects of InnovaStroy will certainly advise you on all the existing options for finishing and facing.

To get a durable and energy-efficient house from aerated concrete blocks, you need to decide at the design stage on the type of finish installed at the facility. Be sure to remember two conditions that must be met before revetting a house from aerated concrete:

1. Any external finishing work should be carried out about a year after the house has shrunk and will withstand spring floods and high humidity;
2. The outside cladding is carried out only after all finishing work related to wet materials has passed inside the house. Aerated concrete will act as a conductor for steam and condensate, and will bring out excess moisture.

Failure to comply with these conditions will damage the new house cladding. In the first case, it will crack or change shape, and in the second, it will be saturated with moisture along with the material. In any case, the house will lose all the advantages that aerated concrete provided it.

The specialists of our company will provide the customer with complete information on each type chosen for cladding. The main requirement with which it is carried out exterior decoration of the house from aerated concrete blocks by InnovaStroy masters - ensuring an excellent level of moisture exchange. In fact, it is necessary to ensure the unhindered penetration of moisture, condensate, steam to the outside - through aerated concrete and lining levels. This approach will ensure the safety of the material and the strength of your cottage.

An insufficient level of ventilation of facades or the use of low-quality materials will lead to saturation of aerated concrete with vapors, accumulation of moisture. As a result, the house will be cold and will not be able to contain the heat, dampness will appear and even fungus may develop.

Naturally, our designers and architects will advise you the better to tile the house from aerated concretebut the final choice will be yours. Below we will consider all the options for exterior decoration of a cottage or a private house. Even if you are planning to build a summer cottage for temporary use, cladding is definitely needed so that your summer cottage will stand for more than a decade.

How to veneer the facade of a house made of aerated concrete?

The modern market of finishing materials is able to offer customers a huge selection of varieties and types. Some are classic, while others show a modern twist in design and architecture. Whatever you choose, be sure to contact the specialists who know exactly how to properly coat a house with aerated concrete, make an estimate of costs, and ensure fast order execution.

Brickwork

The most popular type of cladding, which is always in demand, as it gives the house the appearance of a building built precisely from this material. Clinker or decorative brickwith original shades and a smooth surface. This type of exterior decoration has several severe requirements, without which all work will be useless:

1. Before revealing a house made of aerated concrete with bricks, you need to set a sufficient width of the foundation at the design stage. A wall of aerated concrete block, you need to provide a place for the width of the brick, and the recommended space for ventilation is from 10 centimeters. The outer surface of the cladding cannot extend onto the foundation edge by more than a third of the brick width. This will achieve greater stability and strength of the structure;
2. The ventilation gap is made in two ways, which are equally suitable for gas block houses. First, the width of the space is equal to the transverse dimension of the brick. Then you can lay the cladding across and keep enough space inside for the passage of air. Second, a polystyrene plate is used, which moves along with the masonry. Thus, a uniformity of the gap is achieved over the entire height of the wall, and it also prevents penetration cement mortar into the resulting space;
3. Reinforcing metal components. It can be ordinary cut wire with a thickness of 3 centimeters, mounting strips or fittings. Its installation is carried out in the seams and poured with a cement mixture. You should never bend these parts so that they are located in the seams of aerated blocks and facing bricks. This compromises the strength of the structure and does not affect stability in any way. The mounting method is of two types, which are equally used. The first - the metal reinforcement fits into the seams of the cladding with one edge, and the second is driven into the goose concrete mass to a great depth. The second method is exactly the opposite, when the metal is mounted in the seams of the main wall, and is installed in the facing according to the situation. The main requirement is the presence of at least four such strips for each square meter of the wall;
4. It is imperative to leave "air vents" - holes through which air from the outside will flow under the skin. Most often they are arranged under the upper cornice and at the very bottom. Appearance resembles a normal gap between bricks, only without cement mortar;
5. If brick cladding is made without a ventilation gap, then it is necessary to lay internal materials with a high degree of moisture transmission - insulation, waterproofing, reinforcing mesh.

Laying of decorative or natural stone is done according to exactly the same principle as brick cladding. All conditions and requirements are saved and not subject to change.

Ready ventilated facades

This category includes several types of facing material. It can be plastic or metal siding, natural or plastic lining, ceramic tile, metal finished panels. The advantage of this method of exterior decoration is that the house will look modern and stylish. If necessary, part of the cladding can be easily replaced. A unique feature of this type is that, by its own technical parameters and installation rules, the material has a space for ventilation between the cladding and the wall. IN standard version it can be as little as 3 centimeters, but for a house made of aerated concrete blocks, it is recommended to increase the space to 10 centimeters in order to lay the vapor barrier and insulation.

Such construction of houses from aerated concrete in Moscow and the region is in great demand, as it allows you to significantly save on building a cottage. The specialists of InnovaStroy quickly fulfill the assigned tasks. It should be noted that given view lining does not require additional reinforcement or expansion of the foundation. Due to its low weight, the finish has almost no effect on design features houses.

Plastering and painting

Covering aerated concrete walls with simple materials is also possible, based on the wishes of the customer and his financial capabilities. Painting or plastering can be carried out on the finished wall or on the surface of the insulation. The main requirements in the described case are:

• Leveling the wall surface from the influx of cement or glue mixture, correcting protruding masonry segments;
• Use a primer that does not form an impenetrable film. That is, it must be moisture and vapor permeable;
• Mandatory reinforcement with a special mesh. This requirement especially applies to building corners, window and doorways;
• Breathable use textured plaster and paints to ensure moisture removal from walls and insulation;
• With complete insulation, you should also select a material that can let steam out. Fastening of the layers is carried out using dowels and self-tapping screws with external linings.
