Aerated concrete blocks have become a trend with an individual building. Increasingly, they are also used in multi-storey construction when the internal walls are laid out of them, as well as the outer walls in the frame-block buildings.
ATTENTION: Aerated concrete is considered in this material. In construction, another material is applied with similar name - a gas-silicate concrete (gas-silicate). This is a completely different material and components, and according to the characteristics. It has very little cement, only 14%. Therefore, all recommendations for aerated concrete blocks for it are unacceptable - there is practically no clutch with cement-sandy mixtures.
Gasoblock - Compact and lightweight building material. Its laying during the construction of the walls does not require special skills, which allows people without special construction education to build warm and inexpensive housing with their own hands. At the same time, this material is very "capricious" in the decoration issues.
Features of the aerated concrete in the technology of its production. This is the only building material that has through fine channels, creating two serious wall problems:
The first problem is solved by the walls of the walls both indoors and outside, in connection with which the question "should it be plastering the walls from aerated concrete blocks" disappears by itself. With high vapor permeability, you can only cope with the competent use of finishing technologies.
There are even minor mistakes for nonsense of the nuances finishing work May have fatal consequences. For example, from the order of plastering walls inside and outside the building directly depends on its durability, which will be discussed below.
Preparing to plaster the surface of the walls of aerated concrete blocks, the following points must be taken into account:
What is plastering the walls from aerated concrete inside the house? There is no unambiguous answer to this question. If you buy ready-made plaster mixes, then there are no problems in addition to the financial component. There is always dry plaster on sale on a different basis:
For reference: there are also acrylic mixtures on sale, but it is better to use them for decorative plaster.
Purchase of finished plaster will seriously affect family budgetTherefore, it is necessary to consider the options for self-preparation of the solution. So what plaster is better to stucked the walls from aerated concrete? Here are two blocks of responses depending on the type of prepared clutch of the wall with plaster.
In the first case, it is necessary to take into account the characteristics of the material:
That unusual combination The properties of the wall immediately strikes out the mixture list cement mortar with sand. It is very bad on such a surface even when applying high-quality primer.
Here you need to use:
In the second case, any combination of the components of the solution, including cement and sand in a ratio of 1 to 5, is allowed.
Starting work on applying a plaster layer, it is important not to be mistaken with the number of purchased material. Immediately, we note that it is absolutely accurately calculated how much that it is possible is impossible - it is impossible to take into account all the surface drops of the wall in height, as well as the presence of a vertical. But, with a slight error in any direction, calculations can be made.
It should be started with the definition of an area that needs to be attached. For this, the length of each wall is multiplied by its height and fold the results obtained together. From the resulting number, we subtract the area of \u200b\u200bdoors and windows. The final result is multiplied by the averaged plaster thickness, as a result of which we obtain the amount of solution in m 3.
For reference: The last factor is an average result of the addition of the most thick and smallest layers of plaster, which is determined during the installation of beacons.
The following tools and devices will be required to work:
Attention: experienced professionals enjoy two rules. Short, not more than 1.5 m, - it is more convenient to ram the applied plaster, long - check the quality of the work performed.
ATTENTION: Details of the appointment of each tool and their photos can be found in the material "".
Walking of walls from aerated concrete indoor to start with surface preparation. From quality preparatory work Largely depends the durability of plaster. Many years experience shows - work should be performed in a clear sequence:
ATTENTION: The technology of fulfillment of the above work is described in detail in the material "Preparing surfaces for plastering".
The next, the most responsible stage of work in plastering aerated concrete is the provision of adhesion (clutch) of plaster with the wall. Here are two options: apply a solution on a primer-treated wall or on plaster grid. The second option is gaining popularity, so consider it in more detail.
To work, it is necessary to buy a deep penetration primer for aerated concrete (Ceresit), tile glue (for ceramic products - KNAUF, UNIS 2000, etc.) and a plastering mesh of fiberglass.
Step-by-step instructions are not very complex.
Attention: to breed glue for tiles and work with it in strict accordance with the instructions printed on the package.
Passing the surface of the glue is not allowed. Works are carried out alternately for each mesh canvase. Each subsequent grid should go to the previous 10 cm. For convenience of docking, along the edge of the strip-treated strip, a spatula is performed by several vertical bands (subsequently, during operation, they must be redone into horizontal stripes).
What is plastering the walls from aerated concrete inside the house when reinforcing the wall with a plaster grid and tiled glue? Such a combination of the reinforcing mesh with glue allows you to use any type of plaster used currently in construction.
When building a house of aerated concrete, you should not hurry to separate the walls both inside the building and outside. Even put on glue, the blocks will still give shrinkage - they have a property. What happens to the plaster, on the posterior shrinkage wall, it is not necessary to explain - solid cracks and the complete replacement of the plastering layer.
Experts argue that after the construction of the wall, it is necessary to wait 7 months, and only after that start plastering. However, this recommendation cannot be accounted for. The simple erection of the walls does not lead to their shrinkage - no pressure on the blocks. Only after the construction of the roof begins a full-fledged shrinkage process. Therefore, the countdown should be conducted from the end of the work on the construction of the roof.
How to plaster the walls from aerated concrete indoors? The technology of plastering the aerated concrete walls indoors is the same as for other types of walls.
For reference: in the overwhelming majority, the beacons for walls from aerated concrete are not installed. This is connected with a flat surface of the wall after laying blocks - strict geometry of material and thin binding seams allow you to easily withstand the vertical. We use guides of lighthouses only with the loss of verticality, which occurs as a result of the foundation. The process of their installation on the wall is set out in the work "".
The plaster of walls from a housekeeping indoor is one of the current issues in the construction of gas blocks. The fact is that the material needs to be placed in a number of reasons, the main of which are the purity and smoothness of the surface, since without additional measures, the finishing layer will be poorly held. To be clearer, in all these nuances, it should be understood in detail.
Aerated concrete blocks are characterized by ease of operation: the material is warm and easy. This contributes to their trouble-free cut to obtain the required dimensions. However, it may be quite a logical question, why do you need a plaster aerated concrete? The fact is that the blocks have a smooth surface, which will not allow the finishing layer normally. In this case, the choice of plaster mixtures for the gasoblock should be approached particularly carefully. Wall shockting from the inside allows you to solve the following tasks:
It should be borne in mind that aerated concrete, as in foam concrete, the structure is cellular. Therefore, plastering should be carried out in compliance with technology. Otherwise, air circulation is disturbed, which leads to a deterioration in the properties of the material. Plastering of walls from aerated concrete outside the room is also necessary. Exterior finish protects the effects of precipitation and accumulation of harmful gases and dust.
The gasoblock due to its porous structure is easily absorbed by moisture, so it must be immediately protected from such a negative impact. If the building material wureswards, there is nothing critical in it. However, it is not worth allowing freezing of water in the block. As a result, cracks may simply appear, the strength will decrease, while hurrying with a facing to anything. After completing the walls, the walls must dry. Therefore, aerated concrete walls need to be plastering only in warmth. If the blocks are stacked not on a special adhesive mixture, due to which the seam of a small thickness is provided, the break time is increasing.
There are situations where in the warm season there is no possibility to fulfill finishing work. In this case, the walls are covered with ground penetration soil, which will reduce moisture absorption. In addition, it is recommended to cover the walls with a polyethylene film. If you adhere to the Soviets of Masters, then the decoration of walls from aerated concrete is best carried out in the period when the temperature at night does not fall below 0 ° C. Depending on the region, such temperature indicators correspond to the time from the end of March to the beginning of October. From the described we can conclude whether it is necessary to plaster aerated concrete walls.
Before finding out how to plaster the walls from aerated concrete, you need to decide on the materials that are suitable for these purposes. Building mixes can be purchased ready or knead themselves directly before applying. To prepare a high-quality solution, it is necessary to use a filler, which uses sand, gravel, sawdust or stone crumb and a binder (hated lime, clay, gypsum, cement). Water is added to these components. The cement-sand plaster and a mixture, which uses harated lime, cement and sand, prepare on a construction site. To date, clay is quite rare.
As for the finished mixtures for plastering, they are delivered in bags in dry form. Their composition includes:
Such mixtures are divided into cement and plaster, for which their properties and features in applying are inherent. Cement-based formulations have a longer drying period, subjected to cracking and sediment. The plaster on a gas concrete is applied with a layer of 5-10 mm thick.
All the mixtures that are listed above have different properties and when applied to building material affect differently. But the question of which plaster is better to stucked the walls from aerated concrete, it remains open. First, consider what is used to protect the outer walls, which are constantly affected by atmospheric precipitation, wind and temperature. As a rule, there are solutions based on cement and sand. They have greatly proven themselves with constant contact with moisture. But the question is - is it possible to use them for plastering aerated concrete? Due to the porous structure, the gasoblock quickly absorbs moisture, as a result of the cement, simply does not have time to gain the necessary strength.
To plaster aerated concrete wall with cement mortar, you need to do it right, i.e. In compliance with technology. For moisture from the construction mixture not absorbed into the block, the surface is required to prepare. For these purposes, it is covered with several layers of primer deep penetration, while each layer must completely dry before applying the following. Before you apply plaster, the wall surface is wetted. To avoid cracking, it is recommended to use the grid.
What to plaster aerated concrete inside the house? Gypsum solutions, in contrast to cement, dry faster, and the surface is less susceptible to cracking. The mixtures are based on gypsum used for partitions and inland wallsSince for external use such compositions are unsuitable due to the constant influence of moisture. The finished plaster mixes in their composition contain various additives and fillers, so that the surface is endowed with cracking and negative impacts.
If there is a choice between the finished mixture and manufactured before use, it is worthwhile to take into account that the properties of dry plaster are more projected. In the process of producing such compositions, sand humidity, quality of cement, accuracy of all components are controlled. As for the mixtures, which are preparing in place, then check the quality of cement is quite problematic, and it is not possible at all. The main disadvantage of dry plasters is a high cost.
To fully answer the question of how to properly fly a fuel surface, starting with tools that will be needed for work. In fact, the tools are used the same as for applying a traditional plaster mix. To prepare a solution, you will need a container that can serve as a plastic bucket or tank. In terms of volume, they must be sufficient for stirring all components.
After falling asleep dry mix in the container, water is added. For mixing the solution use a building mixer or a drill with a nozzle. To achieve the necessary consistency, determine the proportions of water and material on the inscriptions on bags with dry plaster. To work will require such tools:
The plastered aerated concrete is watched by a grater, while the excess solution is removed by halfter. Lights are used to equalize the surface, the solution is tightened with the help of the rule. Mandatory tool to be checked by defects on the surface of the walls - a long rack from the floor to the ceiling. The maximum deviation should be no more than 7 mm.
After resolving the issue, how to plaster aerated concrete, proceed directly to the workflow. As with any other type of finishing, first it is necessary to prepare the surface. Gas blocks need to be cleaned from residues masonry mix And close the seams. As already noted, primer is applied to the plaster. The internal plaster of walls from aerated concrete consists of the following steps:
On top of the draft layer of plaster it is necessary to apply primer. A slag sand is recommended to the primer solution. The application of the finish layer of plaster is desirable to produce with the use of construction mixtures with small-scale sand in the composition, which allows you to get a smoother surface. In the completion of the process, the dried solution is smoothed to make the surface as smooth as possible. As a rule, it is started to smooth out 24 hours after applying. To make the surface evenly, the blocks are sprayed with water.
The final stage is painting worksthat suggest the use of paints. Materials in this case are chosen with a high degree of vapor permeability. After the surface is painted, it is recommended to apply a hydrophobizer, which will increase the durability and strength of the finishing layer. Lifetime interior decoration Depends on many factors. One of the mains is the quality of the materials used, i.e. You should navigate the cost. Characteristics of the gasoblock are no less important, because on the surface of low quality, even a good finishing mixture will be kept well.
The fiscal and common plaster for external work is cement-sand. However, the mixture is not suitable for aerated concrete due to low vapor permeability. For these purposes use mineral, silicate or silicone facade plasters. They have a number of necessary characteristics: vapor permeability identical aerated concrete, good adhesion, have a beautiful appearance. Be proceed to plastering the facade only after the completion of all processes, as a result of which the moisture indoors is distinguished, and the complete drying of the surfaces. Gas blocks must be dry, and the maximum allowable humidity is 27%. If this indicator is too high, water vapors that will go outside will cause peeling the finishing layer. Plaster for aerated concrete facade must be endowed with the following qualities:
Plaster for exterior decoration It can be applied to the walls of the house with a thick layer (thick-layer) or subtle (thin-layer). The thin layer plaster is characterized by the fact that the material is applied in several layers with a thickness of no more than 10 mm. After surface preparation and coating, the ground is applied fine layer of plaster (up to 5 mm) and reinforced with a grid.
For reinforcement, metallic (wire diameter is 0.1 mm, cell size - 0.16 * 0.16 mm) or fiberglass mesh (cell size - 50 * 50 mm). Its installation performs peaks in 50 mm. In addition, the building corners of the building are generated, for which they use a perforated corner with a grid, which prevents the appearance of cracks due to a building shrinkage. Using the spatula, the grid is combined into the applied mixture. The reinforcing material must be installed in the location of doors and windows. Then the plaster layer is aligned and waiting for its drying. The second layer is considered to be aligning, so it is necessary to strive to create as a smooth surface as possible. After the finishing layer is applied and the surface is maintained by subsequent grout. It remains to cover the building outside the paint, apply texture plaster and a hydrophobizer.
Aerated concrete blocks today are incredibly in demand - and not only in private construction, but also when erecting frame-block multi-storey buildings. Products are compact, have a small weight, easy mounted, which allows a person to build warm and inexpensive accommodation with his own hands.
However, raise the walls, and start them under the roof - this is not all. It is necessary to know exactly what to plaster aerated concrete inside the house, and understand how the stucco is generally selected at all. These questions and became the topic of this article.
And aerated concrete, and a gas-silicate concrete belong to the category mesh concrete. There is an opinion that this is the same thing, but there is some difference between them there.
And in that, in another material there is a combination of two binding cement-lime. However, their percentage content is different, resulting in material with completely different strength characteristics.
There is up to 60% of cement in the aerated concrete, and the rest is lime and sand. In gas silicate products, the cement of just 14%, almost twice the lime, and many times more sand. It is clear that if so little cement, then the strength of the products is not the same. In general, the gas-silicate concrete is no longer a constructive material, but heat insulating.
Note! Cement, or rather, products and solutions based on it, always has greater strength than lime and plaster. When creating multi-layer screeds, it is necessary to comply with such a principle: the base should always be more durable than the coating - otherwise, it is inevitably detachable.
The plaster of the inner walls from aerated concrete is performed by a solution twice as long as the strength: M75. It takes cement M400 for its manufacture, and mixed with sand 1: 5.
When the cement brand is raised, its amount in solution should decrease to 1: 6, or even up to 1: 6.7 - this is such arithmetic. Everything is done quite simple, and the lower price of self-seated plaster will allow to significantly save on finishing works.
Now, as for the gas silicate wall, in which cement is very small. Accordingly, such plaster, as for aerated concrete, does not suit it. However, it is impossible to infinitely reduce the amount of binder in the solution - only part of it can be replaced with another, less in the strength of the binder.
It should be noted that best option For alignment of walls from gas and gas-silicate blocks, lime foam blocks, as well as silicate bricks, silicate plasters are. But since they contain liquid glass, and they are very caustic, they do not use them for residential premises - only in production workshops and on the facades of buildings.
Plaster inside a house having lime surfaces can be made of gypsum or lime-plaster mixture. In principle, they are suitable for all types of foundations, but there is one thing, and it concerns the walls erected from cellular concrete.
Given their high vapor permeability, and a similar property of plaster, apply plaster on its basis, indoors are not always appropriate:
In any case, the base before decorative plastering should be aligned as under the shocking of wallpaper. Therefore, the walls should first be aligned with cement composition, and when it dries, plaster plaster decorative for interior decoration can be applied. You will learn about it in more detail from the following chapter.
So, in my story we approached directly to the implementation of internal plastering works on agencies concrete walls. We will try to illuminate the most important nuances of this process, and for clarity we offer to view the video in this article.
Porous surfaces are characterized by the most powerful moisture absorbability, which must be reduced by priming. On the aerated concrete walls it is made abundant than, for example, by brick masonry. For this you need to take not just adhesive primer, but the composition of deep penetration.
Important! Primers are ready, and there are concentrated - that is, they are bred by water in a certain proportion manufacturer, which must be observed. It should not be thought that if you bring undiluted soil, you can, for example, reduce the number of passes. The composition must have a normal concentration.
The first layer is applied abundantly, preferably as a paintopult. You can also take an ordinary garden sprayer for this purpose, with which the trees spray. After the aerated wall lights up slightly after processing, another layer is applied, after which the surface should have completely dry.
Double impregnation significantly reduces the water absorption, but does not eliminate it at all. Yes, it is not necessary - and otherwise how will the solution stick to the surface? The surface of the gasoblocks is very smooth, and for plaster you need to provide good adhesion. Making notches like on a hard concrete, it is impossible here. How to get out of the situation?
After the priming, the task number two is reinforcing surfaces. It is necessary that not only for the best clutch of the layers, but also for the prevention of the appearance of cracks.
This is especially important when the walls are elevated from a gas silicate, which is five times less cement than in gas blocks. The strength of such a base is rather weak, and plaster, even gypsum, will turn out to be more durable, and will work for a gap.
Note! The fact is that adhesive compositions are always modified by polymer additives, which are not simply connected, and glue the surfaces. The layer of glue is thin and durable, it still takes off fiberglass mesh. It is not only an excellent basis for plaster, but also reliably fixes blocks without giving microcracks to appear and expand.
When can I start directly to shuttering? Immediately let's say what to do it right the next day is undesirable.
Even if the surface seems dry, the cement adhesive layer has not gained sufficient strength. It is not scary if the plaster on it will be applied by plaster. If it is a cement solution, then the adhesive layer must be given at least five days - and it is better for a week to a set of strength.
Aerated concrete is a modern building material that resembles a foam concrete structure, but differs in air bubbles located inside. The empty structure of the aerated concrete absorbs moisture well, which requires the outer decoration of the material. The better plastering the walls from aerated concrete, is considered in the proposed article.
For the manufacture of material used:
Tip: acquiring aerated concrete, it must be borne in mind that the pores of the blocks, unlike foam concrete, are open. This determines the features of its use and finishing.
Comparative characteristics of foam concrete and aerated concrete are presented in Table:
Foam concrete | Gasobutton |
In its structure, air bubbles are not connected to each other, which increases the stability of the material to the wet. | Air bubbles are interconnected, which allows moisture to move freely. |
Good quality frost resistance and thermal conductivity. | Gives warm and frozen from frost. |
The inner layer of the plastering layer must be two times the thickness of the external | Walls must be placed indoors, and then on the facade of the building. |
To improve the adhesion, the walls must be cleaned, then it is carefully sanding to remove the upper hydrophobized layer. Because of the poor absorption of moisture, a spray is made to increase the clutch, and then apply the main layer. | Adhesion performance higher |
When the outer surfaces from the aerated concrete should be taken into account its high hygroscopicity.
This requires the use of non-standard plasters, which will not lead to:
For the finishing of the outer surfaces, special facade plaster are used. Special danger for aerated concrete plates - temperature differences and large frosts.
When operating, within the designs, a certain amount of fluid begins to accumulate, which will expand when freezing and can greatly harm the structures of the structure. Mixing aerated concrete bases can be mixtures that have good water-repellent properties that do not prevent evaporation from moisture walls.
For the outer finish of aerated concrete, the plaster must have:
Tip: Winners of buildings from aerated concrete blocks need to be borne in mind that the outer decoration of the walls is carried out only after all internal facing works. Otherwise, when conducting "wet" interior finishing works, the walls will absorb a significant amount of moisture, which will later become evaporated.
If the outer facade is finished before applying the inner plaster, with its intensive evaporation, the external plaster layer will appear from the surface of the aerated concrete. After the interior decoration of the room, you can facing the walls of the house outside with special compositions with the highest vapor permeability.
Tip: You can not plaster facades using standard cement-sand mixtures due to their not enough high vapor permeability properties.
For decoration of the walls, a vapor-permeable plaster for aerated concrete is used, which is well transmitting water vapors, not wing, with good adhesion to the surface of blocks and high frost resistance.
Type of plaster | Features of the material |
Disadvantages of material:
|
|
Disadvantages: a small selection of color gamut, loss external view, due to the sedimentation of dust and dirt on the surfaces of the walls. |
|
Disadvantage: big value, but over time, it is most likely to pay off. In this case, it is appropriate to remember that the miser pays twice. |

The advantages of the composition:
Disadvantages of plaster plaster:

All necessary properties are inherent in light thin-layer plaster, specially designed to finish surfaces from aerated concrete. An example of such plaster can be - Baumit Handputz for wall decoration with their own hands produced in bags weighing 25 kilograms.

Tip: Before plastering aerated concrete with this plaster, you need a pre-cleaned surface of the wall to be sprayed with a Baumit Vorspritze solution.
To choose which plaster is better to stucked the walls of aerated concrete, you need to purchase a plaster composition that satisfies the characteristics:
Before starting work, it is better to get acquainted with the video in this article.
Tip: Building blocks from cellular concrete are quite smooth with almost imperceptible seams. It is not necessary to use for alignment of the surfaces of plaster solutions. It is enough to apply only a thin layer of the mixture.
Instructions for plastered walls offers such an order of work:
Properly selected plaster mixes for aerated concrete blocks allow you to make your home not only beautiful, but also warm, maintaining a long term all your positive characteristics.
What a plaster for aerated concrete is best suited, and how to apply it to it - the owners of the buildings from aerated concrete block are often faced with these issues. In order to highlight the walls, it is necessary to figure out all the nuances of not only building mixtures, but also the material itself.
Made blocks from cement, lime, water, quartz sand and aluminum powder. All components are mixed and entered into a pressure autoclave. There is a foaming of the mixture, thanks to the alkali reaction with aluminum, and a porous material is formed, which is becoming increasingly popular in low-rise construction. The material is light, but at the same time strong enough. It is easy to use, because an ordinary saw for cutting is used.
Besides, aerated concrete blocks Not susceptible to reproduction of mold and fungus, being an environmentally friendly material. Aerated concrete has a bad thermal conductivity, so in the building built on this technology, in the summer will always be cool, and in the winter heat. Although aerated concrete blocks are a popular material in construction, but they still have a little capricious. The fact is that they quickly absorb moisture, which must be taken into account when conducting finishing works. Plaster aerated concrete always begins with the inside of the structure. This is due to the fact that the moisture contained in the construction mixture should have time to evaporate before the outdoor decoration of the building will be performed.
The main advantage of aerated concrete blocks is their ability to "breathe". For this reason, plaster for aerated concrete should not score the pores of the material. In addition, as already noted, the material strongly absorbs moisture, which can lead to its cracking. Therefore, in the process it is forbidden to use, which in most cases are used for draft finishing works.
Choose such mixes that can save the microclimate of the room, pay attention to the compositions specifically designed for cellular concrete. Some specialists offer in the decoration of aerated concrete to use mixtures that create vapor insulation. In this case, the service life of the building increases due to the fact that the blocks are most saturated with moisture.
In modern practice, the following types of materials are used:
The plaster of walls from gas-silicate blocks should be carried out with the observance of the technology, otherwise it will be possible to obtain a surprise in the future - cracking the plastered surface. At the very beginning, inspect the surface for the presence of large chips and glue residues, with which the masonry was carried out. It is suitable to the plates that are combined all these influx. After cleaning the surface, treat it with primer. To save, we do not recommend breeding the finished solution with water, it is better to moisten the wall with a wet roller, then treat the surface with the primer. In dry rooms, simple primer is used, but in the wet it is replaced with the composition of deep penetration.
To create a reliable and durable surface, the internal plaster blocks from aerated concrete should be made on the reinforcing grid. For these purposes, you can use galvanized or fiberglass option. Fasten it on the surface with nails or dowels. On top of the grid, we set lighthouses for which plaster works will be produced. Lighthouses are installed strictly by level at a distance of 130-160 cm. Such length is considered optimal for work, but some wizards can choose it depending on personal preferences and experience. The finished options for lightaches from galvanized steel are in the store, and you can independently make them out of the plastering mixture.
When choosing a reinforcing grid, it is worth a preference to material with small cells.
After completing all the preparatory work, proceed to the lining of the gasilicate. The first thing is sprayed - this is the method of applying the draft layer of plaster. A small amount of the mixture is attached to the surface of a layer of no more than three millimeters. Further, the work is stopped until the solution is captured. In the next step, we apply the main layer. This process is called soil and is to apply a plastering mixture to the surface with a spatula or other tool. So the entire space between the beacons is filled. After that, take the rule. It is applied strictly horizontally to the beacons at the very bottom, and then gradually, making zigzag movements, you need to raise it up.
During the alignment, the tool will remain a solution to be removed and to dow on the wall on top of the bulk or in those places where the recesses were formed. The level of alignment is repeated until the rule is not clean. After the solution is grabbed, you need to get beacons from it (if they were not made of plaster). The remaining after this cavity is lubricated with a plaster mortar with the entire surface. Then the surface give time to dry, after which you need to apply the last layer called the cross. Its essence is to create the most smooth surface, so its thickness does not exceed 1-3 mm.
After all these stages, the surface is smoothed by a grater. Pre-mixed with water with water, we leave it to complete drying, after which you can start. Special attention in the plaster on the gas concrete should be given to the formation of the corners. To do this, use metal or that are attached to the surface and are then shuffled. If there is no possibility to acquire them, then take a small spatula and apply a solution to the surface on one side. After solidifying the mixture, remove the surplus and spend the same procedure on the other side of the angle. If necessary, the surface is cleaned.
As can be seen, the inner of aerated concrete is not such a big job. It remains only to decide than plastering aerated concrete inside the house. The use of quality materials will allow not to worry about the reliability of the finish, only from time to time you need cosmetic repairs.
