How to plaster an arbolite house from the inside. We study the main stages of plastering walls from the inside and outside

Finishing the house from wood concrete inside and out

Arbolite houses have a number of significant advantages in comparison with houses built from other materials.

Such buildings not only have excellent thermal insulation qualities, they are environmentally friendly and affordable for most developers. In addition, everyone can do it, and there is no shortage of materials for their manufacture today.

Unfortunately, in addition to the advantages, it also has a number of significant disadvantages. The main one is the high hygroscopicity of the material, it simply absorbs moisture like a sponge. In addition, arbolite blocks do not always have the correct geometry, but here, of course, a lot depends on the technology of their manufacture.

Be that as it may, but all of the above minuses of wood concrete, in the most negative way affect the decoration of the house from it, both inside and outside. About what materials are used to finish the walls of wood concrete and will be discussed below.

The house is being finished from wood concrete inside and out, for various reasons. The exterior finish of the wood concrete house will be required not only to give the building a beautiful and complete appearance. It is very important to protect its surface from the harmful effects of external factors.

In particular, as mentioned above, wood concrete houses are afraid of moisture. Under its strong influence, they begin to gradually collapse, which is fraught with large financial waste. Therefore, immediately after the walls are distilled from wood concrete, it is recommended to protect them with a layer of finishing material.

A variety of building materials can serve as a finish for the exterior walls of an arbolite house. However, the most common of all is the usual plaster mortar. simple and affordable to perform, and the appearance of an arbolite house will not be worse in the end than a brick or cinder block structure.

No less popular materials for finishing wood concrete walls are lining and its varieties, for example, a block house. These materials are fixed on a pre-assembled frame made of metal profiles or bars. However, before you carry out the exterior decoration of wood concrete houses with wooden materials, you should think carefully and protect them before use.

Also, the decoration of an arbolite house with facing bricks is very popular today, and the technology itself is practically no different from finishing a building made of materials other than arbolite.

Finishing houses from wood concrete inside

Inside, the wood concrete house, as well as outside, is most often plastered. However, completely different ones can be used for these purposes, including bayramix, for example, or any others.

At the same time, it is worth understanding the importance of choosing the right finishing materials for the walls of a house made of wood concrete in such rooms as a bathroom and a bathroom. Here, it is better to use plaster, because otherwise moisture will constantly collect under the crate, which will inevitably lead to damage to the walls over time.

Starting to finish the house from wood concrete, you need to properly prepare for this difficult process. Today it is not difficult to find videos and recommendations on the topic of wood concrete houses on the Internet. So, having thoroughly studied the information and weighed all the pros and cons, you can gain and save not only on building a house, but also on finishing it.

Plastering wood concrete blocks is considered the simplest and most reliable way to finish them in order to decorate and protect them from moisture. Moisture-resistant, yet breathable mixtures, distributed in a thin layer within 20 mm, have optimal characteristics for application. It is recommended to process walls on both sides, the difference is manifested only in the solutions used and the technology of their installation. The result achieved largely depends on the quality of the products and the evenness of the masonry; in order to avoid mistakes, it is worth studying all the requirements in advance.

The choice of compositions for plastering

The need for mandatory protection is easily explained, with all its advantages, this composite building material has a high degree of water absorption (40-85%) and is not intended for open use. At the same time, it is not advisable to close it with an impermeable lining due to a decrease in the ability to air exchange and the inability to remove accidentally accumulated condensate from them. This rule applies both when processing walls outside, and when working indoors. The application of moisture-resistant, but porous and breathable mixtures solves this problem completely, the resulting coating combines protective, leveling and decorative functions.

1. Cement-sand mortar, applied with a layer of up to 2 cm. This variety is selected mainly for rough finishing, including when planning to close the outside with a system of ventilation facades. It is valued for its low cost, resistance to moisture and most external influences, but inferior to other types in permeability, the maximum effect is achieved when protecting rooms with high humidity, unheated and outbuildings: garages, workshops, baths.
2. Lime plaster, characterized by increased vapor permeability and plasticity and mainly used for rough finishing of wood concrete walls indoors. In facade work, it is used in combination with water-repellent paints.
3. Gypsum mixtures ideal for interior cladding.
4. Decorative compositions based on acrylic or silicone resins, water glass or complex binders. These types have different characteristics, common properties include good hiding power, wear resistance and the ability to change color by introducing pigments. Silicate or silicone grades have the best UV resistance, permeability and water repellency, they are practically not subject to contamination and do not need to be updated for a long time.

The plaster layer is used as a draft, leveling, heat, sound or waterproofing and acid-resistant, in some cases their functions are combined. Each of the listed varieties has its pros and cons; it is impossible to call any of them universal in relation to wood concrete. Cement-based grades with minor additions of gypsum or lime, which positively affect the vapor permeability index, or water-retaining impurities, are widely used.

In order to avoid errors, it is recommended to use specialized dry mixes; when preparing it yourself, it is important to monitor the degree of permeability of the introduced components. Heat-insulating types, foam glass, crushed slag or foam plastic chips cannot be introduced during their mixing, the optimal combination is achieved by combining a cement or complex binder with crushed expanded clay, perlite, vermiculite or similar breathable filler. There is no need to introduce antiseptic or anti-corrosion additives, wood concrete has a biostability group V and does not need additional protection from any external influences other than moisture.

The features taken into account include ensuring a high quality of adhesion, the applied layer does not need to be reinforced with a mesh or pre-treatment with soil. This is due to the same permeability and elongated shape of the chips, the solution penetrates into the top layer and is securely held between the individual fibers. But this property has a negative side - high consumption of materials and the risk of cracking due to the rapid absorption of moisture from the plaster.

On average, 34 kg of DSP, 30 of lime mixture, 9 of gypsum-based finishing and 8 of decorative types are spent on facing 1 m2.

When performing a rough finish of arbolite blocks, the thickness of the applied layer is maintained within 20 mm, finishing - 7-10. Expensive silicone, acrylic and silicate varieties are spread over the plane with a brush, trowel or wide spatula. The thickness of their layer after drying does not exceed 1-3 mm, but for obvious reasons they are not applied directly to the surface and need a rough base. At the same time, it is recommended to treat the walls outside the house with brands with high UV resistance; acrylic ones are inferior to silicate ones in this regard.

The nuances of the work

The sequence of actions depends on the novelty of the structures: plastering of newly erected systems is started immediately (treatment with soil is required only if there is doubt as to the quality of wood concrete), previously operated - after the removal of old building materials and thorough cleaning of weak particles. Masonry from factory blocks or slabs, as well as a wall poured using monolithic technology, does not need to be hardened auxiliary beacons, they can be processed without prior preparation. An exception is made only when building in hot weather - the surface is gently moistened.

Arbolite houses today are one of the most common. Arbolit combines all the advantages of concrete and wood. This building material is very unique and various technologies are used for its decoration. The principle of finishing is that it is necessary to avoid materials that can harm the wood concrete. Due to the fact that the arbolite has a large-porous structure, it is necessary to finish the arbolite in order to prevent the penetration of moisture. If moisture gets inside the material, it will begin to collapse from the inside. The type of protective and finishing coating is determined in each case depending on the purpose of the building, its location, as well as on the amount of funds invested in construction.

How can you plaster wood concrete

The main way to finish a house from wood concrete is plaster. Since the surface of the material is rough, the adhesion between the wood concrete and the plaster is as high as possible. In this case, there is no need for preliminary preparation for finishing. Although many experts recommend stuffing a metal mesh for better grip. It is also believed that this can significantly extend the life of the finish. Fixing the mesh is very simple, just nails and a hammer.

You can apply the following types of plaster:

• Cement plaster. The composition includes sand and cement. For a wall with a standard thickness (30 cm), the thickness of the plaster layer should be 20 mm.
• Gypsum plaster. The main component is gypsum with various fillers.
• Lime plaster. The base is lime. After applying a layer of plaster putty on the primer. After these works, some developers paint the walls with facade paint.
• Decorative plaster. It happens lime, acrylic, latex. Acrylic plaster is one of the most convenient. It exists in the form of ready-made mixtures. It has very good vapor permeability, which is a great advantage for wood concrete.

What can veneer wood concrete

Another way of cladding the exterior walls of a house is wall cladding. The materials used are very diverse - siding, lining. In addition to them, brick finishing is carried out. In this case, several tasks are solved at once - houses acquire some kind of armor and additional heat and sound insulation is created. The properties of wood concrete allow facing without insulation, however, at the request of the developer, a layer of mineral wool can be laid. For wood concrete, this will only be a plus, since this material will allow it to "breathe". It is important that a gap of 4–5 cm is observed between the wood concrete and the brick, this will help to avoid moisture. Also, with brick cladding, it is important to install ventilation systems. Otherwise, the wood concrete may be destroyed by moisture.

You can use vinyl siding for cladding. These panels retain all the properties of wood concrete and allow the walls of the house to breathe. In addition, such a finish looks aesthetically pleasing and is very resistant to external influences, such as moisture. But there is a minus in the form of deformation from high temperatures. Use of Block House panels as a finishing material. It provides for a mandatory frame of bars on which the panels themselves are attached.

Clapboard lining has become very popular. Lining allows you to visually align the walls. If the walls themselves are even. then you can mount the lining directly to the wall. If there are any flaws, then you can use the already familiar crate. In general, the installation of lining is carried out according to the same principle as siding panels or Block House.

What is the difference between the interior finish of wood concrete and the exterior

The interior decoration of wood concrete also has its own characteristics. Of course, here the main place is given to plaster. It is applied according to the same principle as the outer lining. It is very important to know that during work and during the subsequent operation of the house, the humidity should not be more than 70%. Do not use this building material in buildings where there will be aggressive conditions. It is worth recalling that substances that improve the characteristics of wood concrete are important in the composition of the plaster. These include perlite, which, in turn, is a good insulation. After that, the walls can be safely painted or wallpapered on them.

Also from the inside, the walls are trimmed with clapboard. For its installation, it is necessary to install a wooden crate. This will hide communications, and will not interfere with vapor permeability. As a minus, an increased fire hazard of this material can be noted.

Another option for interior cladding is drywall. A frame is also required. The appearance of the plasterboard cladding is very attractive. In addition, drywall allows you to create any form and embody all ideas. In most cases, finishing work requires the installation of a crate. It is important that these works are carried out with high quality, since the crate will have to withstand the weight of finishing materials, communications and insulation.

Finally

When building walls from wood concrete, it is important to remember that it intensively absorbs moisture. Therefore, it is necessary to wet the blocks before laying. This is done to prevent the solution from drying out. This advice is especially relevant in dry and hot weather. It is also important to make good waterproofing between the foundation and the walls, because arbolite blocks are 80% wood. Without insulation, wood concrete will draw moisture from the soil into itself, making rooms and walls damp. This will lead to the destruction of the house.

Wood concrete is a very unique building material and various technologies are used for its decoration. Plastering walls from wood concrete with a plaster mixture is the first and main way of exterior decoration of a house. The principle of finishing is that it is necessary to avoid materials that can harm the wood concrete. Due to the fact that this building material has a large-pore structure, its finishing must be carried out to prevent the penetration of moisture. If moisture gets inside the material, it will begin to collapse from the inside. The type of protective and finishing coating is determined in each case depending on the purpose of the building, its location, as well as on the amount of funds invested in construction.

Since the surface of the wood concrete is rough, the adhesion to the plaster will be as high as possible. In this case, there is no need for preliminary preparation of the material for finishing. Although many experts recommend stuffing a metal mesh for better grip. It is also believed that this can significantly extend the life of the finish. Fixing the mesh is very simple, with nails and a hammer.

There are two options: either we use only rough plaster, which we close with a ventilated facade, or we veneer the block with a rough and finishing mortar. The first layer always plays a protective role, the second (finishing with a decorative mixture or mounting panels / lining) - aesthetic.

Now that it is clear which solutions we need, we will choose the most suitable one.

Rough plaster

• Cement-sand mixture. The most common and cheapest type of plaster mortar. For a standard wall width of wood concrete (300 mm), a layer of 20 mm is needed. It doesn’t “breathe” very well, but it’s suitable for rough cladding (especially when it comes to garages, workshops, wood concrete baths);
• Lime plaster. The base is lime. Slightly more expensive than cement plaster, but has greater vapor permeability. Fully retains the properties of wood concrete, and protects no worse than cement-sand. After applying a layer of plaster putty on the primer. After these works, some developers paint the walls with facade paint.

Tellingly, a reinforcing mesh for plastering walls made of wood concrete is not needed: the large-pore structure of the block already plays its role. If the wood concrete block is produced according to the correct technology (specifically, without mold lubrication with industrial oil), then there will be no greasy spots on it, and the plaster will lie evenly and firmly.

Finishing plaster

Finishing solutions are, in any case, those that are applied to the rough layer: at the same time, they can play the role of a decorative coating or be intended for painting. Accordingly, they are divided into two large groups - decorative and ordinary. The second type also requires the use of a primer - to adhere to the paint.

• Gypsum plaster. The main component is gypsum with various fillers;
• Decorative plaster. It happens lime, acrylic, latex. Acrylic plaster is one of the most convenient. It exists in the form of ready-made mixtures. It has very good vapor permeability, which is a great advantage for wood concrete.

So, how can you plaster walls from wood concrete

1. Rough plaster + crate + ventilated facade
2. Water repellent + crate + ventilated facade
3. Rough plaster + finishing plaster + primer + paint
4. Rough plaster + finishing decorative plaster

Some specialists add lime paste (about 0.5-1 parts) or water-retaining additives to ordinary cement mortar.

However, it should be borne in mind that when adding some additives (polystyrene foam, foam glass or slag), the walls will “breathe” worse. This is due to the different vapor permeability of materials, resulting in the formation of a dew point (the walls freeze through and become covered with wet spots inside). If you do not want to disturb the air permeability of wood concrete, then it is recommended to use expanded clay, barite, perlite or vermiculite as additives.

Plastering walls from wood concrete

The process of applying external plaster on wood concrete differs from the processing of other concretes in its simplicity. It is possible to apply a protective layer almost immediately after construction, it is not necessary to treat the surface or use reinforcing meshes.

The use of a reinforcing mesh in the process of plastering walls from wood concrete will increase the service life of the finish, but even without it, the plaster composition will firmly “stick” to the surface.

Considering that wood concrete does not require either insulation or reinforcing mesh, in the end it will turn out to be a more economical material, but the consumption of rough plaster on the wall will be twice as much as, say, on ordinary concrete. This is because the solution also enters the cavities between the chips, and not just on the surface itself. True, due to this there will be better adhesion to the block.

Plastering walls from wood concrete can be done using only one regulations or with the use of auxiliary elements - lighthouses. If you use the rule without resorting to beacons, you can save a lot of time and labor. There is no special procedure there: the mixture is thrown in a small layer and leveled with special tools - the rule.

Rule for plaster

When installing beacons, several points are already required:

1. At a distance of 300–400 mm from the corners, marks are made on the wall and lines are drawn perpendicular to the floor;
2. Other lines are also drawn between them, with equal intervals between them. The optimal segments are 1.5 meters each (in any case, a little less than the length of the rule);
3. Pieces of gypsum or a specialized mixture for fixing beacons are placed on the drawn lines;
4. Beacons themselves are attached to pieces of gypsum - segments of a metal profile;
5. Between the beacons, plaster is thrown with a layer of no more than 50 mm (in the case of a good wood concrete block that does not need to be leveled, this is 20 mm);
6. The rule is to level the mixture on the wall: add the missing one or remove the excess.

Beacons for plaster

After the mixture has completely dried, the beacons are dismantled (which is why they are not fixed thoroughly), and plastering work is re-carried out in place of the torn beacons. They can be left if the plaster is just a rough finish for the installation of a hinged facade.

The use of lighthouses (a kind of "rulers" from a metal profile on the wall) is a measure for those cases where the surface does not have an ideal geometry: usually this applies to old houses. Then they serve as an additional (apart from the level) reference point. The problem is this: after the plaster has completely dried, the beacons will need to be removed and the left "grooves" plastered.

If you are finishing a newly built house from wood concrete, there is no need for beacons - a good block has ideal geometry, and deviations in the surface do not exceed 3 mm. With such an indicator, the rule will do just fine.

What are the advantages of plastering walls from wood concrete

When applying external plaster, you can significantly improve, since such a coating performs the following functions:

• Heat shield. The house retains heat without the effect of "steam room". Due to good vapor permeability, external plaster allows the wood concrete to "breathe";
• Soundproof. If the plaster is not painted, it will reliably protect you from unwanted noise;
• Waterproofing. Plastered wood concrete repels water, so rooms with high humidity (but not more than 70%) do not require additional finishing. To enhance the water-repellent properties when applying plaster, it is recommended to use a shotcrete machine;

Also, external plaster for wood concrete is required if aggressive acid vapors are exposed to the walls of the building.

In addition, the plastered facade of the building should be updated no more than once every 8-9 years. To do this, it is enough to “walk” along the walls with a primer, spending a minimum of money on this.

Due to its positive properties, wood concrete is a versatile and durable material for building a house. However, when using wood chip-filled concrete, the high degree of water absorption of this component must be taken into account. Based on this, the facade (and sometimes internal) decoration of this material is a prerequisite. Most often, plaster is used for these purposes. To figure out how to plaster the walls of wood concrete yourself, first of all, it is worth considering the features of this finishing method.

Advantages of plastering wood concrete walls

When applying plaster on wood concrete, you can significantly improve its characteristics, since such a coating performs the following functions:

• Heat shield. The house retains heat without the effect of "steam room". Due to good vapor permeability, the plaster allows the wood concrete to "breathe".

Plastering is also necessary if aggressive acid fumes are exposed to the walls of the building.

Another plus of plaster is its composition, which forms a rough surface, which makes it possible to achieve a high level of adhesion of the plaster material to the wood concrete surface. In this case, you do not have to additionally process the walls and prepare them for finishing.

In addition, the plastered facade of the building should be updated no more than once every 8-9 years. To do this, it is enough to "walk" along the walls with a primer, spending a minimum of money on this.

If we talk about what exactly can be used to plaster walls from wood concrete, then it is worth highlighting several types of this finishing material.

Plaster compositions for wood concrete walls

For self-finishing surfaces from wood concrete, it is recommended to use the following types of plasters:

• Cement. A mixture of sifted sand and cement is suitable for standard walls with a thickness of about 30 cm. The plaster is applied 2 cm thick.
• Plaster. Gypsum and various fillers are used as a finishing material.
• Lime. The main component is lime. In this case, after covering the surface with plaster, it is puttied over the primer and painted with facade paint.
• Compositions for decorative finishing. Such plasters come in different types: lime, acrylic, latex and others. Acrylic composition is considered the most convenient to use. Also, decorative mixtures are characterized by high vapor permeability.

Some specialists add lime paste (about 0.5-1 parts) or water-retaining additives to ordinary cement mortar.

However, it should be borne in mind that when adding some additives (polystyrene foam, foam glass or slag), the walls will “breathe” worse. This is due to the different vapor permeability of materials, resulting in the formation of a dew point (the walls freeze through and become covered with wet spots inside). If you do not want to disturb the air permeability of wood concrete, then it is recommended to use expanded clay, barite, perlite or vermiculite as additives.

The process of applying plaster on an arbolite surface differs from the processing of other concretes in its simplicity. It is possible to apply a protective layer almost immediately after construction, it is not necessary to treat the surface or use reinforcing meshes.

Healthy! The use of a reinforcing mesh in the plastering process will increase the service life of the finish, but even without it, the plaster composition will firmly “stick” to the surface.

Nevertheless, before you quickly plaster the walls of wood concrete yourself, we recommend that you familiarize yourself with some of the features of the external and internal decoration with various materials.

Features of internal and external finishing of arbolite walls

If you plan to use plaster as a cladding, then you need to consider that this building material should not be used for interior decoration of premises with aggressive conditions.

Mixtures for plaster, which include perlite, are good heaters, so after processing the surface can be pasted over with wallpaper.

Also, lining is used for interior decoration, however, such a lining has its drawbacks:

• high cost;
• high fire hazard;
• during installation, it is necessary to prepare a wooden crate.

For interior decoration, drywall is used, with which you can make any shape and create a unique design of the room. However, it also requires the preparation of a frame.

If we talk about how to cover the walls of the house from the outside, then the same plaster will be the cheapest and most affordable option. Some prefer brick because of its heat and sound insulation characteristics, but in addition to its high cost, it requires constant maintenance. Although it is not necessary to prepare a layer of insulation during the installation of bricks, a gap of 40-50 mm must be left between the wood concrete and the brickwork to avoid moisture. In addition, a good ventilation system must be installed for brick cladding, otherwise the wood concrete blocks will quickly collapse.

If you plan to do the work yourself, while spending a minimum of effort and money, then it is better to give preference to ordinary plaster.
