Materials for exterior finishing of aerated concrete houses. Exterior decoration of a house made of aerated concrete or foam blocks
















The interior decoration of a house made of aerated concrete serves not only for decoration, but also performs a number of functions for insulating and protecting walls. Since aerated concrete is a porous material, its condition is greatly affected by air temperature and humidity, therefore the external and internal finishing of aerated concrete walls acts as a natural protective barrier. This means that it is important for owners to know what materials to choose for cladding and how to apply their properties in practice.

Features of interior decoration of walls made of aerated concrete blocks

Due to its porous structure, aerated concrete has high air permeability. If the wall does not have interior decoration, warm water easily seeps through it room air. In the wall cavity it cools to the temperature of the outside air, forming condensation that accumulates in the pores of the material. Thus, walls made of aerated concrete without finishing create large heat losses and become damp due to the formation of condensation.

The main task of interior finishing of a house made of gas silicate blocks is to reduce the permeability of the walls, that is, to “seal” the material from the side of the room. For this purpose, special plaster, plasterboard or wooden sheets are used. Decorative wall decoration on this basis can be of any type.

Aerated blocks are quite affordable in terms of material compatibility - they can be paired with both plaster and wood Source asm.ru

Types of materials and methods of interior decoration

IN modern construction exists big choice finishing materials for aerated concrete. Thanks to this, choosing the cladding to suit your taste and budget is not difficult.

For rough finishing of aerated concrete use:

    plaster;

    plasterboard sheets with insulation.

For decorative finishing aerated concrete can be used:

    paint and varnish compositions;

    textured plaster;

    wooden or plastic sheathing.

For the right choice you need to imagine the properties and advantages of each of these materials.

Plastering walls

Using plaster, you can level the surface of walls for painting or wallpapering. However, ordinary cement-sand mortar is not suitable for finishing aerated concrete walls indoors. Special plaster mixtures are used in construction, which have the following parameters:

    They retain moisture, so when applied it does not penetrate into aerated concrete;

    Improves the adhesion of plaster to aerated concrete;

    Make the solution more flexible and comfortable to apply;

    Accelerate the hardening process of the mixture on the wall;

    Increases the strength of the coating;

    Eliminates cracks during application.

It is better to entrust the work of applying plaster to aerated concrete walls to professional craftsmen. The surface is quite difficult to level due to the texture of the blocks and uneven seams. It's also important to note that plaster takes a while to dry, so finishing the entire house may take several days or weeks.

Drywall

An alternative to plaster is the installation of plasterboard sheets. The method of laying the material depends on the evenness of the wall. If the blocks are laid flat, the drywall is simply glued to the wall. This method If the wall requires leveling, you will have to install the sheets on metal carcass with a layer of insulation.

Drywall is an ideal basis for any decorative finish. It can be covered with decorative plaster, painted and wallpapered. Sheets of plasterboard can be used to cover all rooms in the house.

Wood

Wood is an environmentally friendly material and has a beneficial effect on the microclimate of the house. This type of home decoration looks very cozy. If you do wood cladding throughout the house, it will completely look like a real log house.

Wooden cladding goes well with aerated concrete walls due to the technical similarities of the materials. Both wood and gas silicate have a porous structure and good thermal conductivity. However, the lining is subject to mandatory treatment with water-repellent and antifungal varnishes.

The most popular types of wood for home decoration are pine and spruce. They are characterized by high strength, aesthetic appearance and a pleasant pine aroma.

Laying ceramic tiles on aerated concrete is recommended in rooms with high humidity - a bathroom or kitchen. The tiles will create a protective barrier that will prevent the walls from becoming damp from steam and condensation.

To lay tiles you need to use a special glue that will create good adhesion with aerated concrete wall. Ordinary cement mortar is not suitable for these purposes; you need a sealed composition with antifungal additives.

When covering walls made of aerated concrete with tiles, you must additionally take care of a powerful ventilation system so that moisture does not linger in the room. This is the only way to avoid the appearance of fungus and mold in the bathroom.

Wallpapering walls

After puttying or covering with plasterboard, the walls can be covered with any wallpaper. It is worth considering their breathability. Eg, vinyl wallpapers create additional protection for aerated concrete from moisture and temperature changes. Paper fabric is more “breathable”; it is recommended to combine it with a dense layer of plaster.

The technology for gluing wallpaper on a wall made of aerated concrete differs little from the standard one. Before starting work, the wall must be primed. Otherwise, the recommendations related to the type of wallpaper and the base for gluing are followed.

When choosing wallpaper, the main thing is to choose not only the material, but also the design Source qes.ru.net

Painting the walls

Painting the walls in a house made of aerated concrete is done on top of plaster or plasterboard sheathing. Most often used for finishing water-based paint one of four types:

    acrylic;

    silicone;

    silicate;

    mineral.

In order to additionally protect aerated concrete from water, it is used acrylic paint, which has moisture-repellent properties. Silicone and silicate paints are vapor-permeable, so they require laying reliable plaster.

Before painting, rough finishing of the walls is required - primer, plaster or drywall Source reference.com

PVC panels

Installing plastic panels on a wall made of aerated concrete is a budget-friendly and easy-to-implement finishing option. PVC panels can be different colors, and also imitate the texture of wood or stone. The main condition for their installation on aerated concrete is the presence of a waterproofing layer. This is especially important when finishing a bathroom or kitchen. Also, PVC panels suffer from temperature changes, so they should not be used in finishing balconies and hallways.

PVC panels are quite nice and budget solution Source 1zoom.ru

    Finishing mixtures must be selected based on their compatibility with aerated concrete. Any company has building materials with this mark.

    Instead of conventional leveling plaster, you can use a decorative textured mixture. You won't be able to stick wallpaper on it, but paint will look very impressive.

    In order for the cladding to serve for a long time and perform its functions, the house must be organized coercive system ventilation. This primarily applies to the bathroom and kitchen areas.

Conclusion

Since finishing walls made of aerated concrete indoors plays an important role in maintaining the home microclimate, you need to know and understand the difference between the popular options for cladding rooms. Only after selecting the material required according to its characteristics, you can proceed to choosing the most beautiful and suitable look finishing.

Types of materials for external finishing of aerated concrete blocks

Finishing a house made of aerated concrete from the outside does not require the application of protective coatings. Contact of unprotected aerated concrete with the atmospheric environment leads to a change in the properties of aerated concrete and seriously deteriorates appearance, so I advise you to protect aerated concrete:

  • facing brick;
  • textured, vapor-permeable paints;
  • siding, ventilated facades;
  • special vapor-permeable plaster mixtures that preserve the ability of aerated concrete to “breathe” and protect it from moisture.

When choosing the type of finish, you need to know that aerated concrete is perfectly permeable to steam and air. If the finish is not air-vapor tight, this will lead to moisture accumulation between the aerated concrete and the finish. This moisture will intensively destroy the material and the structure itself.

I do not recommend protecting aerated concrete with cement-sand mixtures, polystyrene foam boards, film-forming paints or dense adhesives.

Finishing a façade made of aerated concrete with textured special paints over vapor-permeable putty is simple and inexpensive way. The cheapest is the “Prospectors” paint.

  • The paint is diluted with water, mixed thoroughly and applied with a roller to the gas block. It is convenient to change the color of the paint by adding pigments. I don't recommend saving on paint.
  • Preparation consists of processing the protruding irregularities with a jointer and grouting the seams.
  • I recommend starting painting a month after preparing the base, so that the chemical reactions in the materials are completed.
  • If the aerated concrete is of poor quality, there are a lot of chips and unevenness, you can apply thin-layer vapor-permeable plaster.

IMPORTANT

Paint consumption is about 0.4-0.6 kg/m2

External aerated concrete wall finishing sheet materials reliable way protect the building. The house can be sheathed with vinyl siding, clapboard or ceramic, metal sheets, vertical or horizontal method installations.

  • I recommend attaching the sheathing sheets to the sheathing.
  • Install the sheathing on nails or expansion anchors. The sheathing creates a ventilated space of 2...4 cm, which is extremely useful for removing condensation and additional insulation.
  • Vinyl siding is often the best way to protect aerated concrete. Available in sizes 385x25.5 cm, thickness 1 mm.

Calculation of quantity of material

Divide total area surface per area of ​​one panel, get the number of required panels
Don't forget to add 7% to the resulting number, which will be spent on processing corners and difficult places

Facade thermal panels are a composite of foam plastic, glass wool on extruded polystyrene foam and marble chips on the outer surface.

Thermal panels are lightweight - they do not load the foundation, are attached to aerated concrete using construction adhesive, and are made of high quality material.

Today thermal panels are the most easy way protection of aerated concrete and additional insulation. The sheathing is not installed on the wall; you can glue the thermal panels yourself.

Facing brick finishing

Protection of aerated concrete with facing bricks should be carried out with a gap of 30...40...50 mm. Brick and aerated concrete walls must be connected with flexible connections. This is usually fiberglass or perforated steel.

In new masonry, connections are inserted into the seam between the masonry during the masonry process itself.

“Clinker tile” panels are a two-layer composite of polyurethane and German high-quality clinker tiles Stroеher, Feldhaus Klinker. Attached directly to the facade with dowels without preparatory work on aerated concrete. After installation, the seams are unstitched.

Tile consumption

Divide the surface area by the area of ​​one tile and multiply by 1.07

Preparation of the base, regardless of the type of finish

I advise you to start the external finishing of aerated concrete walls with preparation work surface walls. First, repair defects in joints, chips, and seams. This is more of an event to insulate the building. It is useful to apply a “warm seam”, seal voids and seams polyurethane foam. Putty the seam.

It will be very good if the primer is covered with a waterproofing compound deep penetration, then the fungus is guaranteed not to appear.

Helpful information

conclusions

The leaders at the lowest cost with a clear advantage are vinyl siding and thermal panels. Using them to protect an aerated concrete wall is half the cost of painting or building a brick wall.

German clinker tiles for cladding aerated concrete cost twice as much as Brick wall. The manufacturability of siding and thermal panels allows you to do the work yourself.

This is the most optimal material for protecting aerated concrete on walls.

The widespread use of aerated concrete blocks is due to their at an affordable price, lightness and strength. But problems may be due to the fact that this material does not look very good. High-quality exterior finishing of a house or other building helps improve the situation.

Peculiarities

Construction of urban and suburban buildings from finished parts industrial production becoming more popular year by year. But you should not think that the exterior decoration of the walls of a house made of aerated concrete will negatively affect the overall price of the structure or worsen its practical qualities. As practice shows, it is not at all necessary to make a finishing layer or install hanging screens that completely mask unattractive masonry. Of course, all types of finishing materials and elements are selected taking into account the increased permeability of aerated concrete to water vapor and its tendency to absorb water.

Finishing blocks from the outside, according to experts, does not always require the creation of an insulated layer.

If the elements used are thicker than 40 cm, then in ordinary climatic conditions RF(except for the northernmost regions), the material itself provides a decent level of thermal protection. Considering that aerated concrete is most often purchased in order to save on construction, any Additional materials and the designs must be cheap. Mechanized application of plaster mixtures (if it is decided to use them) is quite possible. For this purpose, both industrial and home-made devices are used.

Advantages and disadvantages

Anyone who wants to save money as much as possible and simplify their work has a logical question: is it worth finishing aerated concrete or not? In many information materials one can find the statement that the decorative layer has a purely aesthetic purpose and there is no practical need for it. But in fact, there is at least one plus - aerated concrete needs to be finished because it allows a lot of water vapor to pass through. At the same time, the finishing material should be selected with exactly the same level of vapor permeability, which limits the choice. If you violate these rules (do not finish the outside of aerated concrete or do the coating incorrectly), you may encounter a sharp reduction in its shelf life.

Brick

It is impossible to veneer an aerated concrete wall with bricks without preparing a mobile sheet, the thickness of which is 4 cm. This sheet will provide a technical gap from the wall to the masonry. Air will begin to circulate in the resulting gap, therefore the problem of the different abilities of the two materials to pass steam is automatically solved. Before covering the outside of a private aerated concrete house with brickwork, you need to make sure that the foundation can withstand the increased load. Ideally, such a decorative element should be included in the working design.

Please note that brick finishing:

  • increases resistance to water;
  • makes the structure stronger;
  • very difficult to implement;
  • costs a lot of money.

Siding

Sheathing a house with siding can be much faster and cheaper than finishing it with brick. A wide range of color and texture options will undoubtedly delight home owners. Aerated concrete blocks can be completely protected from water penetration; moreover, this finish is very durable and not subject to combustion. Siding does not create a significant load on the foundation and is resistant to ultraviolet radiation. Take care of it, maintain the surface in good condition not difficult.

You can often hear that siding does not tolerate mechanical destruction well. But this is not too important, because replacing damaged blocks with completely new ones can be easily and quickly. Given the relatively low strength, it is worth taking the coating with a reserve. And even if the entire installation went well, there is no need to rush to send this stock to the trash. It may turn out that after a few months or years it will no longer be possible to find sheets of siding with the same color.

Ventilated facades

Facades with an internal ventilation gap are excellent for finishing houses made of aerated concrete. If they are carried out in strict accordance with technical rules, it will be possible to provide both a beautiful appearance and reliable protection of the base material from bad weather. The rate of heating of interior spaces will increase, thermal energy it will spread more evenly across them. Accordingly, the cost of heating resources will be lower. Ventilated facades made of aerated concrete can only be insulated with materials permeable to steam.

Except mineral wool, it is necessary to place a membrane protecting against moisture, which should also allow steam to pass through. This solution will ensure timely removal of condensate to the outside. You cannot use polystyrene foam for insulation, because it will interfere with the escape of water vapor, and very soon the wall will begin to deteriorate. The use of ventilated facade technology, along with improved thermal protection, will muffle street noise. But this method is unacceptable near bodies of water or in areas where there is a lot of precipitation.

The ventilated surface immediately changes the appearance of the building. It can be modified in accordance with any chosen design approach. The facade can last up to 70 years, and the absence of “wet” work allows installation regardless of the weather situation. Work should begin only after completion of all interior works, contributing to an increase in moisture concentration.

To attach a ventilated facade to aerated concrete, use:

  • spring-type drop-down dowels;
  • nylon dowel-nails for universal use;
  • chemical anchors;
  • mechanical type anchors.

Tile

Facing aerated blocks with clinker tiles is no worse than other finishing options. She is gradually relegating her to the background brickwork. It is important to consider that simply applying clinker (gluing it to the wall) will not do anything. In a matter of weeks, aerated concrete will dry out the adhesive mixture, no matter what it is, and after this the tiles will begin to crumble to the ground. This cannot be allowed.

The initial layer is applied with reinforcement with a mesh of metal or fiberglass. Then you need to put an additional final layer of plaster and level it. Only after all the plaster has completely dried can the tiles be installed. To do this, use cold- and moisture-resistant adhesives and create a large seam between the tiles. The minimum gap size is ¼ of the area of ​​the facing element.

Intermediate reinforcement with steel or plastic dowels will help improve the bond between aerated concrete and ceramic plates. They can be replaced with ordinary nails or stainless screws. In all four cases, it is necessary to drive fasteners into the masonry and disguise them in the seams between parts of the clinker mass. Experts believe that you need to make 4 or 5 fastening points per 1 square meter. m. Then the cladding will hold securely and will not collapse prematurely.

Plaster

The plaster layer can be created not only as the basis for a ventilated facade or clinker tiles. With proper selection of the mixture and competent execution of the work, it will become an attractive design solution in itself. It is recommended to use only specialized facade plasters. When working with acrylic compounds, you can count on long-term preservation of beneficial qualities, but you should be wary of open flame (the material can easily ignite).

Silicone plaster, which absorbs little water and is relatively inexpensive, demonstrates a wide variety of textures, but poor color scheme. It should not be used where a significant amount of dust and dirt will fall on the walls. The gypsum composition dries quickly and is not subject to shrinkage, and only one layer is enough for decoration. But we have to reckon with low level vapor permeability and with accelerated wetting under the influence of precipitation. In addition, the surface of the plaster is often covered with stains, they will have to be painted over immediately - there is simply no other way to deal with it.

Painting

But since in this case you will still have to paint the aerated concrete wall, it is logical to look at the use of paint. paints and varnishes this kind is divided into two groups: some contain reinforcing fibers and add texture, while others form an attractive relief. Both types of coloring mixtures can be applied to aerated concrete blocks with a simple roller without additional manipulation. The created layer has a matte tint, the tonality of which can be easily adjusted by color additives. Paints and varnishes for aerated concrete are guaranteed to work for at least 7 years and will absorb some water.

This solution eliminates the occurrence of cracks, and the developers’ refusal to use an organic solvent on water based Helps prevent bad odors. Before applying paintwork, it is necessary to remove all dust and smooth out minor defects using a grater. Staining is carried out either immediately or after façade putty(depending on the complexity of the situation).

Criterias of choice

As is already clear, the external finishing of aerated concrete walls can be done according to the most different technologies. But the manufacturers of each coating are trying to attract the attention of consumers, telling them that they have the best and most reliable, that their solution is ideal for gas blocks.

  • sand and concrete plaster;
  • Styrofoam;
  • expanded polystyrene;
  • covering paint that forms a film.

Simple black self-tapping screws should not be used for fastening the sheathing under a ventilated façade. Dowel-nails showed themselves much better in practice. They do not form cold bridges and are not susceptible to the harmful effects of condensing moisture. The installation step is reduced to 0.4 m - this allows for the most uniform distribution of wind impact load. If you decide to finish an aerated concrete wall with bricks, you will have to provide vents in the lower part of the masonry, and also take care of covering them with gratings.

Please note: brick is worse than other options, because its use creates an increased load on the foundation.

Even if the masonry extends ½ brick, a significant mass is still created. You will also have to take care of flexible connections between the main and outer walls. To summarize, we can confidently conclude that the best results are achieved by using a ventilated façade. Only this technology guarantees both external beauty and weather resistance.

Decorating the front facade of a house is one of the most important tasks that happy new residents must solve, at the very as soon as possible. How will the process take place, and what materials will be used? The solution to this issue largely depends on the main supporting structure of the residential building and on the building materials used during the construction of the house. The opinion of experts agrees on one thing - finishing the facade of a house made of aerated concrete blocks has great importance. This is due, first of all, to the unique specific structure of aerated concrete.

Features of aerated concrete houses

The porous material is produced on the basis of mineral binders and siliceous filler, and is considered one of the varieties of lightweight concrete. Not so long ago, cellular artificial material used exclusively for arranging internal thermal insulation. As a rule, this is insulation of floor slabs, creation of reliable thermal insulation of multi-layer wall structures or thermal protection of pipelines during cold periods.

Characteristics of aerated concrete

IN Lately aerated concrete blocks have gained great popularity as a structural wall material. Buildings built from cellular concrete have better thermal characteristics and have a number of positive qualities.

  • Despite this, it is quite difficult to cladding a house built from aerated concrete:
  • During the construction of load-bearing structures, no violations or inaccuracies are allowed; all flaws in the work will be visible even after high-quality decoration; external design of walls must be carried out in compliance with all construction technologies
  • , taking into account the high vapor permeability of the material; with sufficient thickness external walls
  • there is no need for additional insulation of the structure;

facing with brick or stone requires preliminary calculations. The foundation may not be able to support the additional weight of the finishing material. Decoration must be carried out after completion of all interior work. Most often everything Finishing work

take place in the warm season.

Options for finishing facades made of aerated concrete blocks

The decoration is carried out with a wide variety of finishing materials. Some types are designed exclusively for working with lightweight cellular concrete. How to decorate the facade of a house made of aerated concrete? Let's look at the most popular types of decoration today. Exterior design facing bricks is rightfully considered one of the best architectural solutions. The hollow structure of the source material makes it possible to provide ideal microclimate in building, and an attractive appearance will help create an interesting facade exterior. In addition, the cladding of the house is durable and resistant to external influences.

There is enough a large number of methods of processing brick and options for laying it. As a result, the building acquires strict outlines and unique design. You can design it in the same style local area and create a brick fence enclosing private households.

Most often, brick facade cladding is used only for multi-story buildings. If a private house consists of two floors, it makes sense to imitate brickwork using clinker tiles. The surface of the tile has the same technical characteristics, as facing bricks.

All work on facing walls with brick is quite labor-intensive and requires certain skills, so it is better to entrust the finishing of the facade to specialists.

Siding

Modern finishing material is considered the most affordable and in a practical way finishing of buildings made of aerated concrete blocks.

Siding has excellent quality characteristics:

  • moisture resistance;
  • non-flammability;
  • light weight;
  • low sensitivity to ultraviolet radiation;
  • not subject to rotting processes;
  • wide palette of colors and textures;
  • ease of care.

Finishing the facade of a house made of aerated concrete blocks is done in two ways: vertical or horizontal. Horizontal panels perfectly imitate a log wall; vertical siding is often used for finishing non-residential buildings.

As facade insulation can be used not only soft types mineral wool, but also hard materials, such as polystyrene foam or polystyrene foam. Aluminum, wood, vinyl, steel or cement siding is used to finish aerated concrete facades. The main condition for the use of one type or another should be the high quality of the finishing material. The service life of the facade depends on the type of siding. Vinyl panels are considered the most durable.

Vinyl siding

Vinyl siding is a prefabricated set of planks of the same type that create a common fabric on the external facade of the building being decorated. Initially, the basis of the material was a homogeneous polymer substance; over time, siding turned into a technologically advanced multilayer material made from several types of polymer masses.

Modern panels meet all the requirements for providing maximum comfort and safety:

  • presentable appearance - the panels look harmonious on the facades of aerated concrete buildings. A wide variety of shades and textures will help the building fit well into general style landscape design;
  • excellent protection - dense “canvas” vinyl siding protects aerated concrete blocks from possible external influences and negative weather conditions;
  • strength and reliability of the coating. The facade finished with siding is endowed with special resistance to mechanical stress and shock;
  • durability - panels made of polyvinyl chloride, with proper care, can last more than half a century;
  • ease of maintenance - no special equipment is required to care for the exterior finish chemical substances, a stream of water and an ordinary soap solution is enough.

To finish aerated concrete facades, it is recommended to use two-layer panels. The finishing material has an inner layer that increases the density and dimensional stability of the panels. To create a more reliable barrier that protects against sunlight and precipitation, polyvinyl chloride panels are coated with a special layer, which significantly increases the service life of the external decorative finish.

Plaster

External decoration of aerated concrete blocks is carried out using specially developed mixtures, which contain additives that prevent moisture absorption.

To properly plaster the facade of a house, you must follow a certain sequence of work:

  • preparatory process - preliminary preparation surface, consisting of cleaning the decorated facade from dust and dirt. After this, the walls are primed with a composition intended for aerated concrete;
  • installation of reinforcing mesh - a mesh made of modern fiberglass or its metal analogue with small cells is used. The plaster mesh is firmly attached to the vertical plane, as a result, this guarantees good adhesion of the solution and the surface;
  • plastering process - dry material is selected plaster mixture and by adding required quantity liquid is mixed into a homogeneous mass. The resulting mortar is used to create decorative plaster.

After the entire plastering process has been completed, you can think about finishing facade. Painting surfaces in one or more different shades will look original. You can decorate the facade with unique patterns by applying a design to the plastered facade using a stencil.

Plaster finishing of the facade is used only if the building built from aerated concrete blocks is located in soft climatic zone, which does not require additional wall insulation. For harsher climates, you can create additional insulation using interior finishing. In this case, the walls are sheathed with clapboard, plasterboard or decorative panels.

Protective painting

After completing the external design of the surfaces, the facade of the house must be treated with a special hydrophobic composition with excellent water-repellent characteristics. A thin layer of water repellent can be used to reliable protection decorative surface of the plastered facade from external influences natural conditions and giving it unique antistatic properties.

If used in the process decorative plaster, then there is no need to additionally paint the surfaces; it is enough to add a filler of marble chips to the last batch of the solution.

Most economical option finishing of aerated concrete facade is the use of vapor-permeable putties and special paints. You can add any color to the ready-made mixture.

If, during the finishing of the facade, unevenness or roughness has formed on the surface, for example, seams or unsightly connecting scars, then they need to be rubbed down and the protrusions must be sanded. Then the surface of the facade is covered with another layer of paint.

Ventilated facades

The entire facade structure consists of a frame for attaching thermal insulation and finishing materials. Various types of siding can be used as a finishing material, aluminum panels or porcelain stoneware.

The front façade can be decorated metal panels containing a layer of insulation. This solution significantly reduces the cost of registration and installation time. Most often, the frame of ventilated facades is made of aluminum, but sometimes certain types of wood are used for this.

Wooden ventilated facade is ideal for buildings, Basic structure which also consists of solid wood. For buildings made of brick or gas block, more reliable structures with increased rigidity and reliability are needed.

The most popular are aluminum facades. The structures are mounted on the outer surface of the building so that between them there is the necessary space for installing an insulating layer and a small space for unhindered air circulation.

Combination options

Today, decorators offer to decorate the plastered surface in unusual style half-timbered This style successfully imitates frame structure, which first appeared in medieval Germany. To create a colorful style, contrastingly colored polyurethane or wooden boards are mounted on the wall surface.

Smooth and monochrome painted surfaces blend seamlessly with a wide variety of finishes. Quite often, decorators highlight the basement, corner areas, windows, pediment and porch. For example, plastered surfaces go well with a foundation lined with decorative tiles or artificial stone.

The exterior decoration of an aerated concrete structure will acquire a unique look and amazing design if decorative PVC panels are used in conjunction with plastering. Siding can be used to decorate the base, piers or balcony parapets.

Cladding a house with aerated concrete is a fairly responsible and necessary procedure. Each of the above finishing materials has its own characteristics and disadvantages, but despite this, any finishing method should be made only from quality material observing the consistency and correctness of all finishing work.

Options for finishing the facade of houses made of aerated concrete.


You can use it to build your own home different materials, but aerated concrete is especially popular. It has excellent thermal insulation properties and allows you to get a truly warm home; the main advantages are: low cost, speed of installation, speed of construction and safety for others. There are few disadvantages, and one of them is the limitation in the choice of materials for finishing (for example, the usual use is not suitable cement plaster, you cannot coat it with film-forming paints). How then to cover the outside of a house made of aerated concrete, and what materials are better to choose for it or alternatives from foam blocks or gas silicate?

Why not every material is suitable for finishing

Aerated concrete blocks are distinguished by their porous structure (the pores are evenly distributed throughout the block, approximately 80% filled with air or gas), hydrophilicity (the ability to absorb moisture) and increased vapor permeability (this unique ability porous concrete ensures rapid removal of moisture from the room). When sawing blocks during the construction process, open pores appear on the surface and, if they are not covered with a suitable protective layer, they will become wet, oxidize under the influence of rainwater, fill with dust, and darken. As a result, the house will lose its visual appeal and lose its thermal insulation properties. When choosing what to cover the outside of a house made of foam blocks or aerated concrete, it is imperative to take into account the described physical characteristics of the material, and not to use finishing that prevents the diffusion of water vapor from the room to the outside. It is important to maintain the wall’s ability to “breathe.”

Thus, in the exterior decoration of a house made of gas silicate blocks, you should not use cement mortar, foam plastic, or film-forming paints.

What facing materials can be used

Having excluded prohibited materials from the list of applicable materials, you can choose the best way to cover the outside of a house with foam blocks from the following list:

  • siding;
  • lining;
  • face brick;
  • decorative rock;
  • mineral plaster (specially designed for aerated concrete);
  • grouting the joints followed by the use of façade textured paint (vapor-permeable).

Features of cladding with siding, imitation timber, clapboard

The most convenient, reliable, and fastest in terms of completion time is the exterior finishing of a house made of foam blocks with sheet panels, i.e. siding, imitation timber, clapboard. In this case, a ventilated facade is created and it is possible to provide additional insulation for the house (for example, using mineral wool - the cheapest, most practical and durable material).

Before cladding a house with foam blocks from the outside, a wooden sheathing is made on the walls of the building, onto which the sheathing sheets are then attached.

The use of vinyl siding, imitation timber or lining allows you to create an attractive and fashionable exterior of the building in the shortest possible time. These materials are durable and can be installed on our own, they do not require additional decoration. They are recognized as the most optimal and rational solution for different designs(for example, they are suitable for the question: how to sheathe the outside of a cinder-cast house).

Brick cladding

Among the options for sheathing foam block house outside, facing brick is recognized as one of the best. It has the highest strength and durability among all existing facing materials; such a house will be especially warm (which is especially important). But the use of bricks should be foreseen at the design stage and a more durable foundation should be built, because the weight of such a structure will be much greater.

Considering that the vapor permeability of cellular blocks and bricks is significantly different, a gap of about 3 cm should be left between the blocks and the facing masonry (this can easily be provided by a special protective sheet that protects the foam blocks from the masonry to protect them from splashes cement mortar). For the gap (also called " air gap) ventilation must be installed; to do this, it is enough to leave several empty seams in the upper rows of the masonry (under the eaves). Also, when choosing aerated concrete or brick for finishing the external walls of a house, you need to worry about waterproofing the base.

Application of plaster compositions

If you choose the best way to cover the outside of a house with aerated concrete, based on the price component, then it will be cheaper to use a special plaster composition developed specifically for cellular concrete instead of sheet panels or bricks. Mineral plasters are perfect; they do not contain quartz sand, but are based on a lightweight filler (this can be perlite sand and some others), which ensures vapor permeability to the material. The quality and strength of the plaster remains high, providing excellent resistance to mechanical damage, exposure environment and the formation of shrinkage cracks. Such compositions are applied in a thick layer, carefully smoothing out all the unevenness of the walls being coated.

Having chosen plastering, in the question: how to sheathe the outside of a block house, do not forget about the need for mesh reinforcement in problem areas (at block joints, kinks and joints of profiles, corners of the building facade, in the area of ​​window openings).

Painting facade textured paint

Facade textured paints are also perfect for decorating the walls of a house made of foam blocks, aerated concrete and gas silicate; their advantage is a wide color palette. You can replace the paint with a thin layer of special vapor-proof putty (such as, for example, “Prospectors”), after the coating dries, the wall will acquire a neat appearance. At the same time, do not forget about pre-grouting the joints and eliminating surface unevenness.
