Mineral plaster for facades - we study the composition, compare with competitors and learn how to apply

The modern market offers a wide range of plasters, but mineral plaster for facades occupies a special place among this variety. Let's try to figure out what the secret of its popularity is, what these mixtures consist of and where the weaknesses lie. And practitioners will learn how the step-by-step application of the currently popular bark beetle texture is carried out with their own hands.

Characteristics and advantages

Any plaster mixture consists of 3 main parts - this is the base binder, fillers and modifying additives. Mineral compositions are made on the basis of white Portland cement and slaked lime, I will talk about the types of fillers a little later, and each manufacturer keeps the composition of modifiers a secret.

Basic performance

It is not realistic to tell about all the manufacturers of mineral compositions on the market, so we took averaged data and, for convenience, combined them into a table.

Types of filler

There are compositions for external and internal work. Between themselves, they differ in the type and diameter of the filler grain. The characteristics of these plasters are similar, but not every filler is allowed to be used indoors. The decorative component of this or that plaster depends on the type of filler.

• Glass - do not be alarmed, such a filler has nothing to do with broken glass with sharp edges, small glass balls are used here. The appearance is quite decent, especially when colored glass is taken.
• Clay - decorative colored types of clay are used for filler. The coating can be both textured and smooth, but it is not advisable to use clay compositions for facades (low strength).
• Ceramics - ceramic granules are a by-product in the production of expanded clay. This filler gives only texture, so the composition needs additional tinting.
• Anthracite - the filler is made from coal. This is a by-product of the mining and processing industry, it is not expensive, but dark plaster is not suitable for every design.
• Quartz is the same sand, only of a larger fraction. The price for it is cheap, but the decorative effect is quite decent. Plus, this filler is absolutely safe in all respects.
• Marble - this noble mineral in facade plasters is represented by marble chips. In addition to a solid appearance, marble filler gives additional strength to the coating.
• Mica - among professionals, such plasters are called terrazitic. Mica particles have a reflective mirror effect, so on a sunny day such facades shine like a Christmas tree.

According to sanitary standards, it is forbidden to use compounds containing mica, glass and anthracite for finishing residential premises. This is explained by the fact that the dust from these fillers is harmful to the respiratory tract of living beings.

Another important parameter regarding fillers is the grain fraction, it also has its own gradation:

• Fine-textured granules - up to 0.5 mm in diameter, in fact, this is already dust.
• Fine textured granules - diameter 0.5 - 1 mm.
• Medium textured granules - diameter 1.5 - 3 mm.
• Large textured granules - diameter 3.5 - 4 mm.
• Rough textured granules - diameter from 5 mm.

For the production of facade plasters, only medium, coarse and coarse textured fillers are used. But for interior decorative coatings, all types of fillers are used, the main thing is that the surface matches the design of the room.

The advantages of mineral compositions

• Since the cement-lime mortar is taken as the basis, such a coating has a unique strength. And over time, the plaster becomes only stronger.
• All cement compositions have high vapor permeability, and the presence of a large fraction filler in them only enhances this advantage. According to the reference data, the vapor permeability of mineral facade plaster is equal to the vapor permeability of cellular concrete and natural shell rock.

• Secret modifiers and a high pH level completely block the development of fungus colonies, molds and other biological hazards, according to the manufacturers.
• Cement, lime and mineral fillers do not burn, do not support fire or even melt, so fire inspectors have nothing to complain about.
• Ecologists also have no complaints about mineral facade coatings.
• Cement-lime plasters can be applied to any substrate. In other words, it does not matter what your house is made of, such solutions fit equally well on wood, brick, concrete and any building blocks, including shell rock and cellular concrete.
• In terms of price, these formulations also win, they are cheaper than most competitors.
• Even an amateur can equip the simplest types of textures with his own hands, I will dwell on this moment in detail a little later.

A few words about the cons

• Cement compositions are hard coatings - this means that when the building shrinks, cracks can appear along the facade. Manufacturers are struggling with this unpleasant phenomenon with the help of plasticizers and fiber additives, but it has not yet been possible to completely eradicate the problem.
• Plastering in general and facade work in particular have always been classified as dirty and hard physical labor.
• The presence of alkali in the composition seriously limits the color range of mixtures, but this problem is easily solved with the help of facade paints.
• It is problematic to prepare such plaster with your own hands, since it is necessary to strictly observe the dosage and sequence of actions.

Main competitors

Silicate compounds - silicate plasters are considered close relatives of mineral compounds, but the so-called liquid potash glass acts as a binder here. The price of this coating is not much higher, but the color range is wider here.

Silicates have a dirt-repellent effect, respectively, such a coating does not need to be cleaned for a long time. The only significant disadvantage that most manufacturers cannot cope with is cracking, strengthening additives only partially help, over time the facade becomes covered with small cracks.

Acrylic plasters - have high strength and good adhesion to the base. Acrylic resins are lighter than cement, so the coating gives less load on the facade. As for colors, initially these compositions are white and are tinted as needed shortly before application.

The level of elasticity of acrylic is average, that is, the coating will withstand slight movements of the base, but it is not advisable to use it for new buildings. Plaster is sold in finished form. Of the minuses, susceptibility to pollution stands out, although such facades are easy to clean.

Silicone compounds - belong to the universal types of coatings. They have a unique elasticity, are easy to apply and look great. There are no problems with flowers here either. Silicone has only 2 relative disadvantages - this is an average vapor permeability and high cost.

Phased arrangement of the texture "bark beetle"

Visually, the texture of the "bark beetle" is a surface, as it were, corroded by bark beetles of the same name. A lot of grooves of small depth are applied to the wall. The direction of these grooves and the color of the coating is chosen as desired.

Illustrations	Recommendations
	Stage #1. The surface is cleaned with emery, all bulges and depressions are leveled.
	Stage #2. The wall is covered with soil a couple of times. This stage is especially important if the putty is applied to the insulation.
	Stage #3. According to the instructions, the finished mixture is poured into water and stirred with a construction mixer. It is important to add the dry mixture to the water, and not vice versa.
	Stage #4. The solution is applied to the wall with a metal or plastic trowel. The application thickness should be slightly larger than the fraction of bark beetle granules (the diameter of the granules is indicated on the package).
	Stage number 5. Take a polyurethane grater and rub the wall with light pressure. The granules in the composition will cling to the grater and roll over the solution, resulting in grooves under the "bark beetle". The direction of grouting is selected individually: vertically, horizontally or in a circular motion.

Conclusion

According to the above recommendations, it will be much easier for you to choose the right type of mineral composition. The arrangement technique is shown step by step, and for those to whom the "bark beetle" is not suitable, there are other options in the video in this article. If you have any questions, write in the comments, I will try to help.

Making your home, apartment worthy is not an easy task. Especially if it is located in the city. The most difficult stage is to determine the quality material for repair. Mineral plaster is a popular type of decoration, insulation. Consists of natural and ecological components. Appears to be dry material. Used for different types of work: facade, interior.

Mineral plaster for interior work is used for wall decoration. Feature of the material: you can strengthen the walls, give relief, which will make the interior unique, expressive, create a design. Plastered walls can be painted in any color, polymeric or mineral paints, varnish. Mineral plaster is used for the “fur coat” relief.

Mineral plaster for facades, plinths of houses is used for outdoor work, the durability of the material will provide a reliable coating. This plaster can be coarse-grained, which will increase the density of the wall, because the outside of the building can be exposed to atmospheric or mechanical factors. The composition may contain hydrophobic fillers, which will provide moisture resistance to the material. Often, plaster is applied on the outside over the plaster mesh to strengthen the strength of the applied layer. Often they make the insulation of the house with mineral wool for this plaster. The finished facade looks like a crumb.

Advantages and disadvantages

Like any finishing material, mineral plaster has a number of advantages and disadvantages.

Specifications

Mineral plaster has exact characteristics, but may vary slightly depending on the manufacturer or type. More popular manufacturers are selkoclot, kreisel, edelputz, ceresit br 082, crystal bolars, knauf. Often for decorative finishing choose ceresit Ct 137 mineral plaster pebble eptk to create a relief. The amount of material used depends on the square footage. Specifications of this type:

• Use after kneading for one hour;
• The composition contains white cement, modifying agents, mineral additives;
• Grain density from 1400 to 1500 kg per cubic meter;
• To prepare five liters of solution, you need 25 kg of the mixture;
• Consumption - 3 kg / m2.

Align or cover the walls of aerated concrete, concrete. It is possible to insulate with foam plastic, mineral wool. With the help of mineral plaster bark beetle, you can make a different coating. For example, as in the photo, the method of covering the lamb.

Comparison with other species

In addition to the mineral composition, there are others. For example, silicone, silicate, gypsum, acrylic plasters. Each of them has its own differences:

1. To work with a silicate look, the surface to be applied must be primed with a material on this very basis. Has a high price. The advantages include a wide range of colors. The layer thickness does not exceed 2mm.
2. Silicone material is the most expensive of those listed. Requires special costs. But it is distinguished by reliability, practicality. The color range has about 200 different colors. Does not fade, moisture resistant, creates thermal insulation.
3. Acrylic plaster has low vapor permeability. Vibration resistant. Thin layer coating.

The technology of applying plaster with a video, which is necessary for work Before applying the finishing material to the walls, it is worth doing the preparatory work:

1. Clean the surface from dirt, dust, stains, remove the old coating.
2. For a rough base, notches are made using a double-sided sharp hammer.
3. If there are cracks, recesses, they are cemented, and then primed.
4. If the surface is uneven, it is leveled with a starting putty (plaster). Apply the same to drywall. First, make the installation of sheets.
5. After the putty has dried, a primer is applied. Thanks to it, the adhesion of the plaster improves.

Tip: when choosing a primer, it is better to buy with the addition of antiseptic components. This will provide resistance to the appearance of fungus, mold.

After preparation, we wait for complete drying and apply plaster (ceresite or bayter) with a spatula. You can mix the solution in a bucket. Lay the mixture on the surface in an even layer. Due to the fact that the solution dries immediately, you need to hurry to create a pattern. Then form a pattern with a polyurethane grater. When working with a fur coat, a spatula or special equipment is used. Let the paint dry and then start painting.

Photo gallery of finished works

Facade mineral plaster has been used in construction for a long time and we will talk about it today. Also on the video in this article you can see all the details of the work and the photo will show some moments.

Facade mineral plaster consists of components such as quartz or marble chips (see Facade plaster with marble chips: types, features, methods of application), lime hydrant, white Portland cement, plasticizers, light mineral aggregates, as well as substances that impart a hydrophobic property composition that allows it to repel moisture.

So:

• Mineral plasters for the facade are diluted with water, the instructions are in the package. Using a spatula, the finished composition is applied to the surface to be plastered, after which a textured roller (see Rollers for decorative plaster and creating a relief surface) creates a relief of the coating. When finishing the outer walls, a reinforcing mesh should be used to strengthen the layer. This approach guarantees reliable adhesion of the solution to the outer wall of the building.

You can not use the grid, using only deep penetration soil, but in this case, you need to consider a couple of points:

1. The thickness of the applied layer should not exceed 30 mm.
2. The depth of the unevenness of the wall surface cannot be large.

If this is not feasible, then the grid cannot be dispensed with.

• Mineral plaster is very unpretentious to surfaces., which allows it to be used for external thermal insulation systems. In the course of work, the prepared composition is consumed economically.
• To be able to perform the work qualitatively, it is worth adhering to a certain temperature regime. Plastering is not performed when the temperature is less than 5°C and more than 30°C. The coating will dry completely after 72 hours.

Benefits of mineral plaster

Mineral facade plaster will help you and save money, since the main advantage of the material is its low price. This is due to the absence of expensive components in the composition of the dry mix, which ultimately allows the manufacturer to sell goods at an attractive price.

So:

• Another advantage of the material is its high vapor permeability. This feature distinguishes the plaster under consideration from others, for example, from acrylic ones, by the possibility of using it when plastering surfaces with low diffusion resistance, such as cellular concrete. Thanks to the vapor permeability, excess moisture is removed from the room air without forming condensation on the wall surfaces and without transferring moisture to the supporting structures. Simply put, walls finished with mineral plaster “breathe”.
• The material has a high pH level, due to this it has good resistance to bio-influences. Mineral plaster is resistant to all kinds of mold fungi, overgrowth and other similar types of biological effects.
• This type of plaster tolerates temperature changes well, is resistant to precipitation, and also has frost resistance and fire safety.
• When dried, the solution does not crack and does not shrink.
• In operation, the surfaces finished with this material show their best side. They are easy to clean and wash, for which all cleaning products are suitable. Mineral plaster is completely safe from the point of view of ecology.
• It is also great to do all the work with your own hands. The price will then be much lower.

Negative aspects of mineral plasters

The main disadvantages of the material can be called the following five qualities:

1. Large labor costs at work. High-quality surface finishes require highly skilled manual labor.
2. A small number of plaster colors, which is due to the alkaline composition of the mixture. True, this shortcoming is easily solved. When the plaster dries, it is possible to give it the desired color with paints for facades.
3. Relatively short operating life. Surface repair will be required after a maximum of 10 years.
4. When preparing the solution, it is necessary to strictly adhere to the recommended dosages and adhere to all technological standards.
5. The finished coating is not resistant to vibration effects.

At the moment, in the building materials market, the leader among thin-layer plasters for facades in the price and quality segment are mineral plasters. This mixture is also valuable because, over time, the lime in its composition is carbonized, due to which the coating gains greater hardness.

Stages of facade finishing

Attention: Mineral plaster for facades is applied only after shrinkage of the building, otherwise the finished surface will crack. The process begins when other types of work are completed. Having finished the installation of the roof, drain pipes, loggias or balconies and measures for organizing external waterproofing, they proceed to plastering the facade of the building.

The plaster composition is applied to the prepared wall surface. To do this, dust is removed from it, as well as all bituminous, greasy pollution and saline stains that have come out.

So:

• When plastering facades, different types of mortars are used, which have different strength characteristics, and also differ in hygroscopicity and porosity. The most common use of cement-sand (see Let's consider how to plaster with cement-sand mortar), lime and lime-cement composition. Choose the appropriate type, based on the conditions under which the operation of the facade and its design features are expected.
• Carrying out work in hot weather, when the air is dry and warmed up above 23 ° C, the surface of walls erected from bricks and blocks must be moistened with water.

Plastered walls made of small-piece materials must meet certain parameters:

• The corners and surface of the masonry should not deviate from the vertical, at a distance of one floor by more than 1 cm, and to the full height of the building by no more than 3 cm;
• It is allowed to deviate rows of bricks relative to the horizontal axis by no more than 1.5 cm per 10 m of length;
• The irregularities of the vertical surface when applying the rule to a length of 2 m should not be more than 1 cm.

Facade plastering involves the application of several layers.

So:

• In the case of facade restoration works, mortars are used that are similar in quality and strength characteristics to previously applied plaster. The restored parts are aligned with the plane of the facade and give the same texture.

Attention: When working on the restoration of the surface of the facade, it is not allowed to use compositions that differ from those already applied in strength to a greater extent. It is not permissible to use a cement-sand mixture when repairing lime-cement and lime plaster (see We prepare lime plaster mortar ourselves), because due to the influence of external factors, it is possible that the repaired areas will peel off.

• When repairing cracks with a width of up to 1 mm, having embroidered them, a polymer-cement composition is used. When it is required to update the surface finished with decorative plaster, another composition is used - terrazitic.
• The mixture prepared for work is applied to the wall with a spatula or grater made of stainless steel. When the solution has thickened, its application becomes more difficult, you can restore the initial consistency by mixing the composition with a drill with a special nozzle. Moreover, it is not permissible to re-add water to the already prepared mixture. The thickness of the plaster layer on the facade is determined based on the fraction of aggregates, on average, the range is 1.5-3.5 mm.
• After applying the solution to the surface, it must be leveled and the excess removed with a grater. When the plaster dries and does not remain on the tool, the finished layer can be given the necessary relief. This is done with a plastic grater, holding it in a horizontal plane. It is necessary to perform plastering of one wall without stops, guided by the “wet on wet” rule. When, nevertheless, you cannot do without a break, it is necessary to stick masking tape along the line on which it is supposed to stop and apply a plaster composition on it. At the end of the pause, the adhesive tape can be removed by removing the remnants of the fresh solution.
• Polymer-based decorative plasters are applied in the same way, although there is one point - they must be delivered to the place of work in a prepared form. Starting to finish, they are mixed and plastering of the surface begins.

Attention: When choosing decorative plaster, among other factors, the resulting surface relief is also taken into account.

The mineral facade plaster is quite simply applied and everything can be done by hand, you can see the entire progress of the work on the video in this article and the photo.

You can give a beautiful appearance to the facade of the house with the help of various finishing materials. It can be brick, wood, siding and plaster. It is noteworthy that it is the latter option that is considered the cheapest and is used more often than others. But at the same time, it requires certain labor costs. But it does look pretty nice. Mineral plaster for facades, which has a rich history, can radically change the appearance of a house, while being considered the most durable type of facade coating.

Plaster as a finishing material for walls and ceilings has been used for thousands of years and is still considered perhaps the most versatile way to decorate various surfaces. She saw the light during the heyday of the Roman Empire, when plastered walls were very popular with the wealthy segments of the population. However, the Romans of medium and low incomes could also afford to decorate housing with plaster.

It is interesting that even decorative finishing plaster appeared in Ancient Rome, since during the production of large stone blocks a large amount of small stone debris was obtained, and the ingenious Romans decided to turn it into decorative plaster. It began to be used to decorate walls and ceilings in temples.

Wall decor with plaster - from ancient Rome to the present day

Now a huge selection of plaster is presented on the building goods market, all kinds of varieties and color variations of this material have appeared. The easiest way to classify them is by the substances that are used in their manufacture.

From this point of view, plaster is:

• silicate;
• acrylic;
• silicone;
• mineral.

Each of these types has its own characteristics and features, which are associated not only with the appearance of the material, but also with the technology of application to the work surface.

At the core silicate plaster are components of mineral origin. And the binder is potassium liquid glass. This material is characterized by low elasticity, has high vapor permeability, is not afraid of dirt, and therefore remains clean for a long time, which is why the walls do not require special care.

Silicate plaster is often used on surfaces that are difficult to process, for example, on cellular concrete, shell rock. It can have a lot of shades and is sold ready-to-use. The main disadvantage of silicate plaster is the likelihood of small cracks appearing on its surface.

The main disadvantage of using acrylic plaster is its "magnetism" in relation to dirt. All dust will surely settle on surfaces covered with this finishing material. Fortunately, plaster is easy to return to its former appearance - just rinse the wall with water, as dirt does not eat into the surface. Also, acrylic plaster is quite difficult to apply due to the high drying rate, so it should be covered with it, if possible, the entire wall at once, taking breaks only when changing to another plane.

Acrylic plaster "Lamb" GRANIKOT ACRYLIC

silicone plaster considered the most expensive. Thanks to the silicone base, you can add any filler to it, for example, quartz sand, due to which the surface, plastered with such material as a real stone, looks like. Silicone plaster does not attract dirt, is elastic, has excellent vapor permeability.

Mineral plaster

Since the article deals with mineral plaster, we will talk about it separately. This building mixture is often called cement, since the binder in it is high-quality Portland cement, as well as lime. There are also various filler minerals in the composition - this is a crumb of granite, quartz or marble. Thanks to this combination of components, a very reliable and high-quality building material is obtained, which is excellent for both interior and exterior decoration of buildings.

Mineral plaster. Thanks to the cement in its composition, this plaster is the most durable among all types of this material.

On a note! There are also facade mineral plasters based on silicates, but they are extremely rare due to the high price of the material.

The main advantage of mineral plaster is its durability. Such a coating is made for many decades and regularly, without crumbling, serves a person. However, this material is more expensive than the same acrylic plaster. Fortunately, this building mixture pays off quite quickly during operation - it will take a long time to re-plaster the walls. Mineral plaster has excellent vapor permeability, is not afraid of exposure to water.

There are quite a few mineral plasters on the market, so among all the variety you can choose the ideal options for finishing the basement, walls, and other surfaces. The material may differ not only in color, but also in the size of the filler fractions - the addition of larger inclusions gives the mixture texture.

Important! When buying plaster of any kind, it is important to pay attention to its compliance with state standards and international requirements. These are the main signs of high quality and reliability of the material.

Types of mineral plaster

Mineral plaster, in turn, is divided into several types. First, all its variety of forms should be divided into two types - decorative and facade. Fortunately, they are not very different from each other. Unless the facade plaster, that is, the one that is used outside the house, must necessarily withstand the effects of various natural factors. In this case, usually the facade type includes just brands, which include large fractions of the filler. For example, pebble plaster can be used to make the walls embossed. Also, additives are necessarily introduced into facade plasters that increase resistance to ultraviolet radiation.

On a note! The consumption of facade mineral plaster is always quite high, since it is usually applied with a layer of at least 5 mm.

In general, both facade and decorative mineral plasters, in addition to providing surface protection and leveling, give it a beautiful appearance and a certain texture. The latter will depend on the type of filler.

Table. Types of fillers for plaster.

Fraction size matters

The final result when applying mineral plaster is strongly influenced by the size of the filler fractions - for example, the following types of compositions are distinguished:

• rough-textured (inclusions of 5 mm or more in size);
• coarse (fraction size from 3.5 to 4 mm);
• medium texture (from 1.5 to 3 mm);
• fine textured (from 0.5 to 1 mm);
• fine textured (less than 0.5 mm).

To finish the facades, you can use types of plasters related to the range from rough textured to medium textured. However, sometimes they acquire more "gentle" options.

Advantages and disadvantages

Mineral facade plasters, like any other material, have their pros and cons, which are associated with the application technology and operation features.

Advantages of mineral plasters:

• excellent vapor permeability, due to which condensation does not form on the wall surface;
• most types are applied easily;
• high strength of the final coating;
• the coating does not crumble over time;
• plaster is not afraid of exposure to precipitation;
• can be used on absolutely any surface;
• it is an environmentally friendly material that does not harm health and does not violate the ecological situation in the territory adjacent to the house;
• the coating is easy to clean, fungi and mold do not live on it;
• plaster is not combustible;
• relatively low cost compared to other types of plasters;
• allows you to easily achieve a uniform coating of the surface of the walls.

Disadvantages of mineral facade plasters:

• when preparing solutions, it is important to follow the recipe exactly, otherwise the result will not be what is expected;
• labor costs must be taken into account;
• during storage, moisture should not get on the plaster;
• surfaces almost always turn out only matte.

Another example of the use of decorative facade plaster

It is possible to work with mineral plasters only manually. So the labor costs in the process of applying the material to the walls will be high.

In terms of technical characteristics, aerated concrete differs markedly from other materials, and these differences must be taken into account when choosing exterior finishes for walls. Plastering is considered the most popular option, and in order for the coating to correspond as closely as possible to the base material, it is necessary.

Usage

The scope of facade mineral plasters is not limited only to the walls of a residential building. Since plasters have excellent strength characteristics, they are also used in other places, for example, in industrial buildings, cafes, restaurants, cultural institutions, railway stations, underground passages, and so on. They perfectly withstand almost critical operating conditions. Mineral plaster is often used to decorate the plinths of buildings, stairwells.

On a note! It is not advisable to use mineral plasters for rough work. Usually they are applied to the already prepared and leveled surface of the walls. But such material perfectly replaces tiles, wallpaper, and any other coatings both outside the house and inside.

Mineral plaster can also be used for finishing buildings located in large cities, since it is easy to clean. It is used in various climatic conditions, as it perfectly withstands changes in humidity and temperature.

Application of mineral plaster

On sale there are a huge number of types of plaster mixes suitable for finishing facades. Let's get acquainted with how to apply one of the most popular plasters - "bark beetle", which includes granite chips with a fraction size of up to 3 mm.

First, let's prepare all the necessary tools:

• construction mixer;
• mixing buckets;
• spatulas;
• steel grater;
• plastic grater (for creating a pattern).

Important! Prepare the plaster mixture immediately before application. It is also important to breed it only strictly according to the instructions.

Step 1. The first step is to prepare the surface to be treated. The wall must be even and smooth - all irregularities are removed, pieces of cement mortar (if any) must be removed. It is better to grind all joints and seams with sandpaper.

Step 3 The plaster solution is being prepared in accordance with the recommendations on the package. The mixture from the package (strictly dosed) is poured into water and stirred with a construction mixer until a homogeneous consistency.

Step 4 The mixture is infused for about 10 minutes, after which its viscosity is checked with a spatula - the consistency of the plaster should resemble thick sour cream.

Step 5 Mineral plaster is preliminarily applied to the wall using a plastic or metal float. Excess is removed with a conventional spatula. The main task of the plasterer is to apply the mortar in an even layer.

On a note! You should not immediately cover all the walls with plaster - it dries quickly, but you still need to apply a pattern. Therefore, the size of the area that can be covered with mortar at a time will depend on the speed of the plasterer and the speed of drying of the mixture. In the case of bark beetle plaster, it is necessary to apply the drawing within half an hour after applying the solution to the walls.

Step 6 Using a polyurethane grater, a texture pattern is formed. The grater is driven in directions up or down over the already applied solution - this is how a decorative pattern appears. First, the grater is carried out strictly along the wall from the bottom up, and the next time - from top to bottom, next to (parallel to) the previously applied pattern.

Step 7 After the plaster has dried, the wall can be painted or coated with special protective compounds.

You can give the walls of a country house a beautiful appearance, decorate a garage or a concrete fence with the help of facade mineral plaster with your own hands. The main thing is to follow the instructions and not rush to finish the job. The design of the facade is a painstaking task, and there is no need to hurry.
