Aerated concrete is a popular building material, from which durable, durable, warm and resistant to different negative impacts are obtained. It has an acceptable cost, as well as construction with it can be carried out with their own hands even beginners. After the construction of the house, it is necessary to decide on which materials will be applied for finishing works. Initially, the walls are covered with high-quality plaster, so it is important to figure out than plastering aerated concrete outside and inside the house, as well as how to perform this work correctly.
Important! It is not allowed for external and internal work to use the same material, as it is important that the coatings are resistant to the existing operating conditions, and they differ significantly on the street and inside the house.
Present plasters on the market in numerous species. Not all varieties are suitable for aerated concrete, therefore, the parameters of each material are predefined, after which the desired option is selected for outdoor use or for internal work.
Important! Plastering for external use should have high thermal insulating parameters, resistance to moisture and temperature changes, and at the same time, it is obliged to provide good sound insulation and have an attractive appearance.
There are several most popular plasters used for aerated concrete. Each option has its own characteristics, so it is important to study the parameters of any kind before a particular choice.
This material is considered in demand for various types of work, but it is precisely for aerated concrete. This is due to the fact that it turns out smooth walls on which cement mortar is well held. Aerated concrete has a specific feature to absorb moisture from the solution. Cement plaster has vapor permeability, which is lower than at the walls, therefore, if applied to finishing works, the microclimate mounted in residential premises can be significantly oblivioned.
Also cement mortar It is characterized by a low adhesion with a fuel-concrete surface. Often, lime is added to enhance this parameter. If all this material is chosen for external work, it will certainly be applied after drying the plaster special finishing layer, which allows you to get a perfectly smooth surface. 
Important! If the vapor permeability of the aerated concrete is broken, this may cause different cracks, mold or traces of seams.
The market presents a special adhesive mixture, designed to apply onto walls made of aerated concrete. She has optimal composition To work with this material, however, its main purpose is the connection of individual blocks, so it is used in the joints.
The material is applied with a thin layer, therefore it is not considered suitable for the formation of the outer layer on the walls of aerated concrete. It will not be possible to make an optimal protective coating, as well as its cost is considered high enough, so it is impractical to use it for this purpose.
This material has many advantages for use on the walls of aerated concrete. To the advantages of it:
But this material is not deprived of certain essential flaws. These include:
Important! Even with many minuses, the gypsum solution is considered relevant for use on the walls of aerated concrete, but is usually used for interior decoration in rooms with a low humidity.
The market presents a special material for walls of aerated concrete, used both for external use and internal. To the advantages of using it for the house, erected from aerated concrete:
It is this material that is selected to finish the structure of aerated concrete most often. It provides a qualitative, uniform and durable layer possessing an interesting view. But this material has a sufficiently high cost, so many money is spent on the finishing of the whole house. For the inner walls, the use of a gypsum solution is considered optimal.
When choosing a material intended for plastering walls from aerated concrete, the basic requirements and criteria that it must comply with. To get really high-quality and optimal coating, Stucket must have:
Important! For each buyer, an additional important parameter is the value of the solution, and it must comply with its quality and properties, but it is not recommended to pay attention to the most affordable material, since it will not have the optimal properties for use on the walls of aerated concrete.
Aerated concrete is considered a specific material that is characterized by good absorbability of moisture, so immediately after the construction of the construction, it is recommended to take care of the protection of walls from water exposure. Wetting the material is not considered critical, but it is impossible to make moisture in aerated concrete, as this may cause cracks or weakening walls.
Important! However, it should not be hurry, since after the construction of the house from aerated concrete, it is recommended to give the material to a thorough bread.
Plastering on aerated concrete exclusively in the warm season is applied. If applied during work cement mixThe drying time is considered significant, and this is due not only to its parameters, but also by the fact that a sufficiently significant layer is created quite significant.
If there is no possibility for applying plaster in the warm season, the walls are certainly covered with a special primer, and it is important to choose a tool deep penetration. The resulting layer reduces the water absorption of aerated concrete. It is allowed to cover the entire structure with polyethylene or other similar material.
There are several options that determine the sequence of the actions necessary for repairing the house built from aerated concrete. These include:
Important! Although modern high-quality plasters have good vapor permeability, they dry out long enough, and this is especially important if the decoration of walls from aerated concrete is planned at the cold season, so it is desirable to leave the process to warm times.
The use of plaster for interior decoration house built from aerated concrete is a simple and understandable process. He is divided into successive stages:
Thus, the process of plastering walls from aerated concrete is a fairly simple process, easily performed by each owner of the house.
Important! It is possible to get the perfect result of work only with accurate following the basic rules and comply with the correct sequence of actions.
Exterior finishing works for the house of aerated concrete suggest creating a sufficiently thick layer. Therefore, several layers are usually applied immediately, as well as reinforcement. The whole process is divided into steps:
Thus, the application of plaster on the walls made of aerated concrete is a simple process. It is easily performed both inside the house and outside. To obtain a qualitative result, it is important to carefully examine the instructions, as well as clearly follow the sequential actions. Other an important point Creating an ideal coating for walls from aerated concrete is the right choice of plaster itself, which must comply with the operating conditions available on the street or inside the house. An article can also be useful.
Recently, using blocks from celebrate concrete Not only carry out thermal insulation, but also erected at home. This material is somewhat "capricious", so the plaster of walls from aerated concrete indoor and the outside should be carried out with regard to some nuances.
Many masters believe that finishing work on the walls from cellular concrete must be carried out immediately after the construction of the building, but this undertaking is quite risky. It is better for this procedure in a year. The fact is that aerated concrete must have time to dry before the onset of cold weather, which can interfere with the plaster layer. If the moisture remains inside in winter, it will freeze, which will lead to the cracking of the material.
First of all should be held inner plaster For aerated concrete, after which you can start finishing the external surfaces. You can even pull a little time by performing internal works in the fall, and the outer late spring. Almost there can be only buildings on the sea coast. In this case, the first thing must be protected outer walls from atmospheric influences.
First of all, internal plaster is carried out, and then external Important! It is strictly forbidden to make plaster at home from aerated concrete from November to March.
Exterior plaster for aerated concrete is completely optional. On the contrary, many masters recommend immediately ordering the walls of such a thickness, which would be enough to ensure comfortable temperature inside housing without the use of plaster outside. Incorrectly selected composition or violation of application technology can lead to the destruction of the entire design.
Many masters oppose the exterior plaster walls from aerated concrete Some advise using polystyrene foam for insulation, but this material is almost impenetrable for aqueous steam. This leads to the fact that condensate accumulates at the junction of the insulation and gasoblocks. In the cold season, it freezes and leads to cracking of cellular concrete. If still it was decided to use foamed polystyrene, then you need to lay a layer of 80 mm, while the thermal resistance heat insulating material There should be no below this indicator of aerated concrete.
On a note! To get rid of the need for additional procedures, it is enough to order a 10 cm thick wall in warm regions, 30 cm in cold, and 20 cm is suitable for bath.
The question of how to plaster aerated concrete outside and indoors is not at all idle. It should be noted immediately noted that the plaster on a gas concrete cannot be carried out with the help of cement-sand solutions.
To properly shock the walls from aerated concrete outside or inside the house, you must use the following compounds:
Before plastering aerated concrete, attention should be paid to thorough preparation of the base. To do this, remove all irregularities through a plane or a special tool for processing blocks from cellular concrete. This process is recommended to perform even at the construction stage, but some builders simply forget about this in order to save time. On the operational properties The future turning treatment is not affected by the plane, but it can be significantly reduced with it when finished.
After that, it is necessary to apply primer. Some wizards dilute the primer with water, but it is rooted wrong. This can be saved a little on the solution, but at the same time the adhesion of the processed blocks will drop significantly, which can affect the duration of the coating operation. To save the primer, it is better to pre-moisten the roller with water and go through the wall, after which it is possible to repeat the procedure, but already with the primer. For wet premises, it is better to use the impregnation of deep penetration, for dry - simple.
For better clutch plaster with blocks, it is necessary to pre-process the walls of the primer Then begin to install plaster beacons. This is one of the simplest operations, since the blocks processed by the plane do not have large drops. Via building level It is necessary to find the most repeating point, add a profile height to the magnitude, and according to the value obtained, set lighthouses throughout the area being processed with an interval of 130-160 cm.
Installation of plaster beacons will allow plaster perfectly smoothly. When the preparatory work is finished, proceed to plastering walls from the gas block. It is carried out according to the following technology:
The plastered coating is covered with wallpaper or color. It is better to use materials based on acrylic, latex, cement or organic solvents as paint.
The plaster of aerated concrete outside can be carried out by two methods: applying into one layer or several. The one-layer option is slightly losing, so it is recommended to stop the selection on the second method. Before plaking the concrete wall, it is necessary to carry out the same manipulations as with the inner wall. After that, you need to install the reinforcing grid.
Outdoor plaster of fuel-concrete walls are performed using a reinforcing grid For these purposes, metal products with wire with a diameter of 1 mm and a side of 16 mm or a fiberglass grid with a cell is 5 cm. This product is cut into fragments of such an area so that it is convenient to work with them. After that, a plaster solution of a layer is not more than 5 mm on the surface, while it is replete to it pressing the grid and blend it.
Then you need to pause and wait for the solution to dry. Check it easy: you need to sprinkle a little water to the coating if the liquid is quickly absorbed - you can continue the work.
In turns with an interval of 3-4 days, two more layers of material of 10 mm are applied. After drying, the plastered surface is drained in the same way as internal.
The last stage of the wall decoration is putting plaster On a note! Before plastering concrete walls, it is important to determine immediately with the type of finish finish. Different types of paint require different types of plaster.
Blocks from cellular concrete rarely require any finish, except for decorative, but if such a need arose, then, first of all, it is necessary to choose the case for plastering aerated concrete, as well as follow the above rules and technologies.
When erecting walls.
Aerated concrete and gas silicate are modern building materials, according to its structure resembling foam concrete, but differing in the structure of air bubbles inside the material.
Because of the void structure, the aerated concrete and gas silicate absorbs moisture well. So the walls from aerated concrete (gas-silicate) can not be left without outdoor decoration.
Among themselves, aerated concrete and gas-silicate are distinguished by the fact that the gas silicate is made from lime and quartz sand, and aerated concrete - based on cement (50-60% by weight). Maintenance physical characteristics Both materials are very similar.
Let's consider the basic requirements of the plaster used to finish the walls from aerated concrete.
In foam concrete, air bubbles are closed and isolated from each other, due to which its ability to resist wetting.
The aerated concrete, on the contrary, has an open structure of air bubbles, due to which the moisture quickly penetrates the material.
It is because of this, aerated concrete rates have lower heat transfer resistance and frost resistance and needs high-quality external and interior decoration that allows minimizing the disadvantaged of the open porosity of the material.
Let's see how to plaster the walls from the aerated concrete and what plaster should be used for this.
Many masters proceed to the plaster immediately after the construction of the walls. In the case of aerated concrete, this can lead to a variety of different problems.
When the walls are erected from aerated concrete, it is best to produce plaster for the next season.
If you need to complete the finish immediately after the construction, then you should carefully treat the selection of plaster, which should have a high plasticity and freely pass the water vapor outside.
The peculiarity of the thermo-concrete thermophysics is rapid wet, long drying and the inadmissibility of oarsaturation with water vapors.
It is recommended when building buildings from aerated concrete first, the inner finish first is performed, and then the outer. For example, interior decoration Perform autumn, and outdoor plaster - in the spring of next year.
Rare exceptions can be at home covered on the sea coast, when it is necessary to protect the walls from a wet wind in order to protect walls from a wet wind.
Another embodiment of the finish can be simultaneously executing the decoration outside and from the inside. But this option is the least preferred.
It is not necessary to rush. After the construction of the aerated concrete should be good, and the process is not fast. As a result of the finishes of a heavy cement plaster of non-dry walls from aerated concrete in cold periodWhen heat becomes warm inside the structure, water vapors begin to move to the outer edge of the wall.
But due to severe steamproof plaster, they have nowhere to go and water vapors fall out in the form of condensate, the freezing of which can lead to a complete separation of plaster from the wall.
A particularly unfavorable time for plastering walls from aerated concrete blocks is the period from November to March.
When performing walls from aerated concrete blocks, their thickness is calculated based on local climatic conditions. As a rule, correctly chosen wall thickness does not require it outdoor insulation. Moreover, in some cases it can lead to the destruction of the construction.
For the insulation of the walls, many advise to use polystyrene foam, believing that it will improve heat physical properties Buildings. However, the material impenetrable for water vapor can cause condensate falling on the border of the insulation and masonry from water vapor, excreted from aerated concrete blocks. Protensate freezing can lead to the appearance of cracks in the walls and further to their destruction.
That is, you should not take the thickness of the walls so that they still need to be inspired. Aerated concrete has high heat engineering characteristics and does not require the construction of high thickness walls to save heat inside the structure.
So, for country houses In the middle band, the thickness of the wall of aerated concrete at 300 mm will be quite sufficient. For the construction of the bath, there are enough wall thickness in 200 mm, and in warmer regions - 100 mm.
In the case of insulation of the structure using outdoor laying of the polystyrene layer, its thickness should be chosen such as to prevent condensate falling on the masonry border and insulation. The thickness of the insulation layer of polystyrene foam or polyurethane should be taken at least 80 mm, and the thermal resistance of the insulation layer should be at least 50% of the total thermal resistance of the wall.
It would seem that the easiest way to prepare the usual cement-sandy solution and stack the walls. But at the same time, there may be problems that have already mentioned above.
As a result of various physical properties of cement plaster and walls from gas-silicate blocks, cracking and disposal of plastering can occur.
Plastering for aerated concrete should be well to skip water vapors, do not wet, have good adhesion to the surface of aerated concrete blocks and high frost resistance.
All the necessary properties have light thin layer plasters, specially created for finishing walls from aerated concrete.
An example of such a plaster mix - Baumit Handputz sand-lime-based plaster for manual finish with grain grain 1 mm, produced in bags of 25 kg.

Before plastering the aerated concrete walls, this plaster is recommended for a purified surface of the aerated concrete Baumit Vorspritzer spraying, which is part of the plaster performed by the type of fine adhesive seam.
For more decorative finish Acrylic plasters are used. It is a very durable material that can be used wherever increased strength.
However, according to vapor permeability, acrylic plasters are inferior to the lime-sandy, and as a result of the decoration such plaster in the thickness of the wall, water vapors can accumulate.
To prevent this, it is necessary to use the enhanced waterproof wall with the inside, as well as an improved ventilation system.
In addition, acrylic plasters are combustible and therefore are used with restrictions.
An example of acrylic plaster for aerated concrete is the Bolix and Bolix Complex plaster.
There are also silicate plasters for aerated concrete. An example of such plaster is a paste-shaped mixture ready to use Baumit Silikattop based on potassium liquid glass.
Silicate plasters have excellent vapor permeability and low water absorption, which is very important when finishing walls from aerated concrete blocks.
By cons of such plasters, it is possible to attribute the extremely melligent choice. color solutions And the loss of appearance due to the sedimentation of dust on the surface of the plaster.
Another type of plastering mixtures used in the finishing of walls from aerated concrete blocks is silicone plaster based on silicon-organic polymers.
Silicone plaster has resistance to atmospheric effects, it practically does not die (hydrophobic), has high vapor permeability, it is easy to apply and over time does not lose its attractive appearance.
The only minus such plaster is a higher price. Such plaster will no longer be attributed to the Economy Class.
When using a Baumit Handputz mixture, the sequence of actions will be as follows.
The bag of the mixture (25 kg) should be poured into the container with 6-7 liters of clean water and mix thoroughly stirrer. The mixing time is 3-5 minutes.
After that, on the wall of the Baumit Vorspritzer spray, which contributes to the best adhesion of plastering to the surface and reducing the moisture absorption of aerated concrete.
The layer of plaster is applied to cells and stretches the rule. After grabbing rubs the grater.
For 2 days, the replaced plaster should be protected from rapid drying.
The layer hardening time is 10 days by 10 mm thick. At this time, plaster from mechanical damage should be protected.
All work must be performed at air temperature at least zero degrees.
For better protection against wetting on top of plaster, a thin layer of the hydrophobizer can be applied. If in the area of \u200b\u200byour accommodation is not uncommon, it will make such a protective layer to significantly shedding the service life of plaster.
In the next publication, consider the stacking process in more detail.
The construction of overlapping from a gas-concrete material has a number of advantages. First of all, it is low weight and low thermal conductivity coefficient. In order to avoid destruction, the wall posted from this material must be subjected to finishing. Due to its porous structure of plastering walls from aerated concrete indoor, it is performed with nuances associated with the preservation of the microclimate inside the house. Therefore, not every finishing material can be applied.
Before you begin to choose the composition of plaster for walls from gaskets, it is desirable to understand what properties they possess and why not every type of finishing material fits. Aerated concrete is an energy efficient material for various kinds of construction. In its parameters, it refers to a group of cellular concrete, as its larger volume is gas bubbles. The advantages of such a building material are:
Working with aerated concrete is easy and quickly. From it you can erect the house yourself without resorting to the services of construction organizations. At about a day, a person can lay up to three cubic meters of gas blocks. The material includes cement, lime, sand, aluminum and water paste. All substances are mixed in a given proportion, the strength of the obtained block depends on the value. The reaction between aluminum paste and lime forms hydrogen. It contributes to the emergence of a huge amount of pores reaching the maximum size equal to two millimeters.
The mixed mass with a passing reaction is sent to the mold, where it is frozen. After the frozen form, cut into type blocks and grind. Despite all its advantages, aerated concrete blocks are a hygroscopic material. And this means that not every finishing mixture is suitable for plastering walls from gas blocks. Due to the high porous structure, the internal plaster of walls from aerated concrete is simply necessary for its protection against environmental humidity. The moisture quickly penetrates into the thickness of unprotected gas blocks through the structure of air bubbles, causing their destruction.
Building technology using aerated concrete is not particularly different from the construction of walls from another type of block materials. The difference lies only in the binder composition for blocks. The connecting seams are performed with the minimum possible thickness to prevent the formation of cold bridges. Therefore, when building walls, glue is used, allowing you to perform seams with a thickness of no more than three millimeters. Thus, the features of the use of aerated concrete are as follows:
The solutions used for the plastering of internal and outer surfaces differ in their characteristics due to various conditions Environmental effects. For outdoor use, they must have not only resistance to moisture, but also not to change their parameters for temperature fluctuations.
Select the plaster is needed with great responsibility. From this choice in the end and the final result will depend. Choosing than plastering the walls from aerated concrete indoors, first of all, the environmental conditions and the requirements for the wall obtained are taken into account. By choosing a construction mixture for plastering, pay attention to the following parameters:
When choosing a mixture, you must pay attention to its marking. It should indicate the main characteristics and the purpose is written - for cellular concrete. Typically, the price of such plaster is slightly higher than that of ordinary mixtures.
In specialized outlets you can find products of various manufacturers. There are several most frequently used types of plaster. Depending on the composition of the mixture, they are: lime-cement, gypsum, silicate and silicone.
Stuccoings based on cement-sandy solution are considered not very suitable. Although from all other species are the most cheap. Such a solution has a low vapor permeability ratio and quickly gives its moisture to the gas concrete. Because of this is disturbed technological process Throy and clutch solution. Therefore, this type of mixture as internal plaster for aerated concrete is almost no applied.
In the case of plastering, it is such a mixture that lime is added to increase vapor permeability, and after drying on top of the plaster, a layer of plaster finish shovetaking is applied. To improve adhesion, primer is used, providing increased adhesion of materials, which levels the difference in price compared to specialized mixtures. It should be borne in mind that the decrease in vapor permeability leads to the formation of mold.
Use of glue used for clutch blocks with each other is undesirable. The adhesive mixture is designed exclusively for applying a thin layer. It will not be possible to perform a smooth protective coating, and the cost of such a material is quite high.
Gypsum plaster is considered the most popular for plastering gas silicate blocks. To its advantages include:
In addition, the gypsum exists and there are deficiencies: mediocre vapor permeability, the likelihood of the appearance of various spots on the surface, the process of the kneading solution requires a large amount of water.
To work with gas-silicate blocks, it is recommended to use special facade plaster. It is she who provides the desired indicator of vapor permeability and good adhesion with the base. Due to the low absorption coefficient, there is no need to apply additional layers of plaster. This type of mixture quickly gains strength, its composition is usually already included for reinforcement. A significant disadvantage is the price.
Choosing the type of plaster, financial capabilities are also evaluated. The cheapest way will be the use of lime-cement composition, but the quality of the finish will be the lowest. Silicate compounds are optimal to combine price-quality, but require additionally putty. Mixtures based on silicone additives are ideally combined with the characteristics of aerated concrete blocks, but they are the most expensive.
Regardless of the selected mixture, before start plastering a degree in the room, it will be necessary to prepare both the tools and the surface. At the first stage, the surface of the overlap is examined for the presence of glue and irregularities in the seams. Defects in the seams are close to the shplanyow, and the influxes are watched with a spatula, a planer or a sharper.
The next step is applied primer. Before applying from the surface, dust is removed, for example, by wiping with a damp cloth. After drying, the primer is already applied. It is distributed evenly over the entire surface. It is easiest to perform this with a roller or a wide brush. The choice of the type of primer depends on the view of the room and the planned to use the plastering mixture. So, a universal soil is suitable for a gypsum solution, and for sand-cement - ground penetration soil.
With insufficient mastery, and for the convenience of plastering, lighthouses are installed. Their height and limits the thickness of the applied solution. They are located on the wall vertically semi. The distance between them is chosen less than three or four centimeters of the length of the rules, and the installation of the installation is determined using a level.
As soon as preparatory stage It will be completed, proceed to directly applying the plaster layer. To do this, using the instructions depicted on the bag with the mixture, the solution is prepared. Standard ratio - 1 kg of plaster on 0.5 liters of water. In this case, it should be noted that with an excess of water, the solution will be spread, and in case of lack, it is cracked.
After the knead, the solution is left for five minutes before the creamy state and is mixed again. Prepare the mixture follows in small portions, even if the surface requiring plastering is large. This is due to the life of the material, which is on average 40-50 minutes, after which its properties deteriorate.
Celma or spatula is used to populate the solution. Walking begins to bottom up with such a calculation so that the layer of plaster overlap the height of beacons. Then by the beacons, making progressive movements, spend the rule as on rails, removing excess.
Once all work is finished and the plaster will freeze, lighthouses are cleaned. Empties formed after their removal are filled with putty. The whole wall is inspected for the presence of defects, if necessary, undercases with a spatula.
At the last stage, the finish finish is performed. To do this, if necessary, grout and schurification is performed.
With the implementation of work on plastering without the use of special tools, it will not be possible to achieve acceptable finishing quality. To work, you will need to use both manual and electric type tool. But at the same time there is a necessary minimum, without which it is not necessary. It belongs to him:
Of course, even at a high level of skill, it will be impossible to achieve even the smoothness of the surface without lighthouses. In addition to the minimum tool, you will need to have a rule, a half-year, grater, a corner spatula, a drill with a wedge for a knead.
The process of plastering is the most common option outdoor finish. With the help of it, alignment of the indoor walls is performed. However, how different is the technology of applying material, if you need to plaster aerated concrete or brick walls? Or maybe you are a happy owner of a frame house or a structure from foam blocks. Today I will talk about the basic principles of applying plaster on the walls with their own hands, as well as we will look at how the stucco is the foundation of the house.
It does not matter, the repair of an old brick building is carried out or the walls of the new construction are made, the plaster is necessary element For high-quality work. Using modern stucco, you can conduct high-quality protection of walls from negative atmospheric influence.
Important! Using the traditional mixture made with your own hands, it is better to handle sufficiently large surfaces. Modern materials have in the components that boost beneficial features Plasters.
The material that will be used for external surfaces must meet important requirements:
Brick walls are exposed to plastering during reconstruction work, since over time, cracks appear on the walls of the house, chips or simply due to uneven masonry during the construction of the house. Brick house You can plaster with your own hands and for this it is enough to adhere to such a sequence:
The brick house often requires additional thermal insulation, which can occur with the help of the well-known foam. In this case, the subsequent plastering is a necessary event.
The foundation of the house is the most an important place The entire structure that is most of all is negative. Protection of the foundation with the help of plaster should be carried out on summit And most often for this should be referred to specialists. But if you want to stack the foundation with your own hands, then proceed by this plan:
As the finishing layer for the foundation you can use different kinds decorative plaster. For the foundation, a solution is suitable for "travertine", terrazitic plaster and a fur coat. It is important that the foundation coincides with the overall design of the facade.
Being sufficiently light and durable material, Foam concrete is very in demand for the construction of the house. The advantages of foam block have long been justified, one for a long service life of the foam block surface must be plastered both outside the house and inside.
The technology of plastering walls from foam block differs from processes for other types of surfaces. However, to achieve maximum effect should be used by some advice:
Performing work with your own hands should be given only to high-quality materials, which will allow the finish process as quickly as possible, efficiently and for a long time.
For a frame house, plaster is also used often as siding panels. Before performing work outside the house, you should choose a way of plastering:
If the decoration of a frame house will be held every 5-7 years, then you can choose the first option. He is a simpler performed by his own hands. However, having spent more time and strength to the second way, you will get a facade of the building, which will serve at least 13-15 years.
If an application and decorative plaster is scheduled for a frame house, then on the construction grid it is possible to apply one layer of the mixture. In the case of single-layer application, clinker can be used for the frame structure, as well as ceramic tiles or stone.
Important! The hydrophobizer is used for plasters as an increase in the water-repellent properties of a frame house. With their help, gas permeability remains the same, but the absorption of moisture is significantly reduced.
For a skeleton house and coating its plaster, all bases should be processed. However, in some cases, it is possible to cover only those surfaces that are most susceptible to the influence of moisture.
Finishing aerated concrete plaster
Aerated concrete is in demand building materialwhich is used in low-rise construction. Popularity This material received thanks lightweight and the rates of construction of houses with it. However, with such positive qualities, aerated concrete has a low thermal conductivity coefficient and therefore requires high-quality finish.
Important! The microclimate, created inside the house of aerated concrete, compare with the microclimate of wooden buildings. Therefore, the plaster of the walls of the aerated concrete is necessary as well as the plaster wooden house outside.
Aerated concrete inside the house must be plastering with certain solutions. The use of cement-sand mix is \u200b\u200bunacceptable, since the material has the property absorbing moisture. Aerated concrete is best finished with gypsum spacing or solutions on a plaster basis. Inside the house, you can apply solutions with such fillers as chalk, marble or dolomite.
Important! There is a special plaster on the modern building market with which the cellular material can be finished without deteriorating the properties of vaporizolation.
To preserve vapor barrier, aerated concrete can be separated by a polyethylene film. However, if all work is done with errors, condensate may appear on the surface of the walls, and the plaster will decide over time. That is why many decide to stucify aerated concrete with a sand-cement mortar, but in this case the coating will definitely begin to peel. Before starting to separate aerated concrete, it should be studied in detail all the advantages and cons of these methods and only after that it takes the design of the walls inside and outside the house. Aerated concrete has different density stamps and need to be remembered that the plaster is selected based on this data. Outdoor plaster at home can be performed independently, all processes must occur in a warm and dry season.
Plasteur aerated concrete walls inside the house
The use of decorative plaster is in demand due to the possibility of selecting the desired color of the material. Due to the fact that there is a huge number of plasters having a color, creating a certain design and its shades becomes a fairly simple action. In addition to using ready-made mixtures, you can add pigment when independent manufacture Solid. However, giving a certain color in one knee there is no guarantee that the color of subsequent rasters will completely coincide. Even when using the same proportions, a small change in color is possible, which will be noticeably on the walls inside or from the outside of the house.
In specialized stores, you can choose the color of the plaster with the palettes of certain manufacturers, as well as to determine the tint together with the catalogs of the already decorated houses with the help of these materials. Remember than saturated tone of plaster, the longer the color will remain. With this saturated dark color Can very quickly lose its appearance.
