Plinth plastering as a way to protect, strengthen and decorate it. We do the plastering of the basement at home with our own hands

The socle is called the part of the foundation that rises above the soil surface. It serves as a transitional support from the base of the house buried in the ground to its walls. This structural element The building performs, first of all, a protective function: it prevents the penetration of wind and water into the underground space and prevents the ascent of moisture through the capillaries of the walls. However, the decorative load on this part of the foundation is also important. If it looks tidy and tasteful, it adds a lot to the beauty of the building. Since houses are the simplest, most developers do just that.

Preparatory work for applying plaster

The basement of a house can be not only a continuation of the concrete monolith of the foundation, but also a separate structure located on it, made of other materials. For example, on a cement-sand belt, a superstructure of bricks, blocks or rubble concrete can be made. She will be the base. Therefore, the preparatory processes before plastering are different for each of the materials.

Brick base.

Its feature is the presence of seams from the solution. Usually over time cement mixture cracks, begins to crumble, cracks and rather large gaps appear on it. Therefore, each seam must be cleaned, removing those of its particles that are weakly held. This can be done with a narrow spatula, pierce with a strong screwdriver, sweep with a brush with metal bristles. After removing the collapsed mortar, all the gaps between the bricks must be swept away, removing dust and sand.

Base made of rubble concrete.

The preparatory stage in this case is in many ways similar to working with bricks. But here special attention should be paid to the strength of fixing stones in the basement of the house. If any of them are found to be staggering, they should be taken out and replaced immediately with freshly prepared cement-sand mortar. This need is due to the fact that rubble concrete old masonry may lose his bearing capacity, and deformation of the base of the house is possible.

Concrete plinth.

If it has deep cracks, you should check how strong their edges are. Weak spots needs to be destroyed and cleansed. If a part of the foundation has shifted and it needs reinforcement, this work is done before plastering. If the protrusions are small, and their alignment is possible cement mortar, this can be done in the process.

Priming of concrete surface

Must buy ingredients deep penetration in such quantity that it is enough to process the entire foundation of the house. It is worth considering that you will need to apply two layers of primer: before you start plastering and after it is completed, before painting or other finishing works. But the composition in the second case should be different: facade adhesive, often acrylic-based.

Many homeowners ignore these processes, believing that surface priming is not really necessary. But the decision is wrong. Compliance with the plastering technology greatly increases the service life of this covering layer. In order not to have to watch in a few years how the solution applied to the base cracks and peels off, do not neglect its priming.

What primer to choose?

Deep penetration.

The purpose of these compounds is to penetrate the surface to the maximum possible depth, while strengthening it. If the plinth was previously covered with plaster on lime mortar, then its traces will certainly remain on concrete or brick. This loose mixture is a serious obstacle to the adhesion of a new plaster layer. Therefore, deep penetration alkyd primer is indispensable here. She will strengthen limestone surface and eliminate the "chalky" effect, will become binder between old and new compositions.

The best choice would be a deep penetration primer with a water-repellent property. This will provide the basement of the building with additional waterproofing protection. It is written on the packages: front (or for exterior finish) water-repellent primer. This category includes Knauf-Isogrunt, Betokontakt from the manufacturers Knauf and Feydal, the Russian Consolit.

In order for the paint to be laid evenly and the surface to be externally attractive, uniform and without sagging, a special acrylic primer should be used. Depending on the basis on which the paint will be made, they buy:

"Acrylate-Grunt" or "Proacryl-Contact" - for decorating compositions based on acrylic.
"Facade-Primer" or "Proacryl-Primer" - for water-based paints.

Plastering the plinth: the rules for preparing the solution

Suitable for outdoor work only. cement composition, not lime or gypsum.

In order for the plaster layer to be strong and durable, the proportions of the mortar should be as follows: 1 part binder grade M400 and above and 3 parts sand. The latter must be carefully sifted and must be of career origin. river sand not suitable for adding to the mortar due to the too small size of the grains of sand, which are not able to form a dense base of the plaster layer.

The mixture needs to be made more plastic so that it is easier to apply and forms a sufficiently even, smooth layer. For this purpose, special plasticizing additives are bought. At the same time, a coloring pigment can be added to the composition, which will give the basement of the house the desired color and will certainly decorate the building. It is highly desirable to supplement the solution with an additive that will give it water repellency. The façade always has to come into contact with unfavorable conditions external environment, one of which is exposure to water or water vapor. The plinth, covered with a waterproof composition, will retain its attractive appearance much longer.

The cement mortar is prepared as follows:

sand is sifted;
added right amount cement, mixed with sand;
if the pigment is dry, then it is added;
the necessary additives are dissolved in water and gradually poured into a mixture of dry components. The solution should have a creamy consistency;

If there is no desire to independently prepare a cement mortar, you can buy any dry mortar. An excellent option is the M-150. When diluting it with water, you need to monitor how “fat” the composition is. If there is a lot of sandy component in it, then add not a large number of any tile adhesive. It will allow the mixture to "stick" to the surface it is treating.

Over time, the plinth masonry not only loses its attractive appearance, but also gradually begins to fall apart. Therefore, the owners are brewing the question - how to fix the situation? One way to protect the bottom of the house from negative impact environment and to give it an attractive appearance, is the plastering of the basement of the foundation.

Types of plaster

Plastering is a very popular type of plinth finish, as it does not require high costs and at the same time looks quite stylish and presentable. In addition, a huge selection of plaster allows you to decorate the plinth with an original texture and patterns.

For finishing, you can use the following types of plaster:

Silicone- the most expensive option, but the cost is justified high quality finishes and its versatility. Such plaster protects the surface from any negative environmental influences, without losing its attractive appearance for a long time. In addition, you can create any colors by combining compositions of different colors.
Cement-sand- most a budget option. Its merits include high strength. To give the composition moisture resistance, special additives are added to it. Such plaster is sold in the form of dry mixes.
Acrylic- great for decorating the basement. It contains various resins that act as a binding base. In addition, the mixture contains special additives that allow the surface to "breathe" and also make the finish moisture resistant.

Advantages

Modern formulations have many positive properties, among which are the following:

Resistance to large differences temperatures.
Vapor permeability. Due to the fact that the compositions are able to let steam out, the house, as mentioned above, can "breathe".
Moisture resistance. will be able to protect the base from atmospheric precipitation, which gradually destroy the structure.
Good sound and heat insulation. Finishing is an additional obstacle to the penetration of cold and extraneous sounds into the house. As a result, a comfortable and healthy microclimate is formed in the room.
Ease of application of the solution, so you can do the plastering with your own hands.
Large selection of colors and textures. This will allow you to create unusual coatings with a beautiful texture and suitable colors.
Affordable price compositions.

Plinth plastering

Surface preparation

Before plastering the foundation base, it is necessary to prepare the surface. To do this, it must be cleaned of dirt, dust, greasy spots and other defects. If there are easily chipped or peeled places in the masonry or concrete, they must be cut down to a solid foundation.

If the plinth is concrete or made of concrete blocks, then the plaster on such a surface will not adhere well and will begin to crumble over time. To prevent its delamination, the concrete structure must be covered with a chain-link mesh.

Note! , which will subsequently be finished with plaster, should be done with empty laying, i.e. without filling seams.

If concrete or stone surfaces have stood unplastered for more than a year, while becoming dusty and covered with soot, then they must be notched, cleaned and washed. Especially carefully should be cleaned surfaces that have been painted with oil paint. If the surface is uneven, then it should be leveled with cement mortar.

Plaster

As a rule, the basement plaster is made in two layers.

The plastering instructions are as follows:

The surface of the base is pre-moistened with water.
Then the first layer is applied, which is called a primer, its thickness should be 8 - 12 mm. The plaster is leveled with a wide spatula.
Next, using a scraper or brush, the surface is roughened. To do this, wavy lines are applied to it with a depth of several millimeters at a distance of 3-4 cm.
Before plastering the basement of the house with a decorative layer, you must wait for it to dry. primer plaster. Reception must be closed with burlap, matting or sheets of parchment and moistened with water for a week. This is done so that cracks do not form on the surface.
After 7-10 days, a decorative (covering) layer can be applied, the thickness of which should be 3-5 millimeters. Plaster can be simple, painted or textured.

Note! When plastering the plinth, it is necessary to monitor the correct dosage of the compositions. If there is not enough in the solution or vice versa, there is too much binder, then the finish will quickly crack and begin to crumble.

Features of plastering

There are several important points, which must be taken into account when plastering the basement:

Do not apply plaster layers on a frozen surface, as the coating will quickly begin to crumble.
Accelerated drying adversely affects the quality of the surface.
When performing layer-by-layer plastering, it is necessary to wait until the first layer has completely hardened.
Before plastering the basement of the house, the surface must be moistened. Otherwise, peeling of the coating may occur.
If, when applying the plaster, bumps are noticeable, which crumble when pressed, it means that the solution is poorly mixed, or milk of lime, which has small outstanding particles. The process of quenching these particles also occurs after applying the solution to the plaster, which leads to coating defects.

Using a chain link

The modern construction industry can provide a huge selection of the most different materials used in the decoration of the basement. Nevertheless, plastering does not lose its popularity. Using modern technologies, this design of the basement can look very original and varied. In addition to the traditional plastering technique for the basement, sand-cement mortar can be made decorative or mosaic. Such a design will not only decorate the building, make it neat and presentable, but also insulate the walls and protect them from destruction.

The plinth is assigned important place in the external structure of the house, it is affected by numerous loads, it performs a number of important functions, one of which is the uniform distribution of the pressure of the mass of the building on the foundation. The foundation, being underground, is not so exposed to the sun, frost, water and temperature changes. Facing the plinth with plaster is an important stage of work to protect the plinth from aggressive influences and give it an ennobled appearance.

as an external protective coating usually use stone, porcelain stoneware, tile, siding, clapboard or other hinged structures. However, the cheapest and most common type of protection for the basement of a house, which is used by builders around the world, is plaster.

Types of plasters for the plinth

Terrazit plaster and its features

The plinth decorated with terrazite plaster will look beautiful and original. The surface treated in this way will become highly resistant to mechanical stress and the influence of water, because the basis of the plaster mixture will be a lime-cement composition, including mineral fillers resistant to aggressive environments.
The surface of the plinth, made with terrazite plaster, has a multi-layered structure. The first layer is a preparatory base, and the second is a decorative one. After applying the primer layer, it is imperative to moisten it with water, and after that apply the top, more presentable layer, leveling it with a special grater. This process is quite laborious and takes a lot of time, however, the result and the further effect will please you.
The top coat is easier to apply by spraying the solution over the cured primer base. A surface made in this way is called a fur coat. It is easy to apply, and its layer is impressive as a result and provides a high degree insulation and water resistance. Not having professional tools, the solution can be sprayed with an ordinary broom.

Stone plaster

Quite in demand is the plastering of the basement under the stone. Rustic, Roman and prismatic masonry are especially popular. The imitation method is often used different types plasters, such as grooved, rounded, chipped, flat, rectangular and square. The essence of this method is to simulate a pattern using special tools.
For stone-like plaster of the basement of a house, they usually use special solution, which simulates the surface of such expensive materials like marble, granite and other analogues. The surface of the base in this case turns out to be beautiful, strong and durable, but applying such a coating is a rather complicated and time-consuming process.

Mixes for plaster

Before dwelling on the choice of material for plastering the basement, study practical photos their varieties with the recommendations of professionals on the pages of any construction online store.

Types of mixtures for plaster

aggregate in the form of crumbs of stone;
plasticizer;
cement.

Base materials are often applied in a semi-dry state using a conventional trowel. The plaster pattern is made using special steel or bronze stamps.

Properties of mixtures for plaster

For outdoor use, cement-sand, silicone, acrylic and decorative plasters are used.

The main properties of modern mixtures:

resistance to frost and heat and temperature changes;
wear resistance in relation to the destructive effects of water and humidity;
invulnerability to steam;
increased sound insulation;
increased thermal insulation;
ease of work on applying mixtures;
variety of textures and rich colors.

Facing the plinth with plaster will protect it from the effects of aggressive manifestations of the external environment, which gradually lead to the destruction of the unprotected surface. Mixtures have the ability to pass steam through themselves, which will also ensure the durability of the base. The protective layer will prevent cold air and excess noise from entering the structure. Applying plaster, even with minimal skills in construction, can be done by hand, and big choice textures and a rich palette of colors will make your plinth unique.

The choice of plaster mixture for the basement: features

The composition for plaster is a combination of various additives and the base - a binder. The ratio of the components of the mixture for the external processing of the base determines its characteristics, method of application and appearance.
by the most economical option today is the composition of the plaster mixture on cement base. Modern brands of this material differ increased strength and resilience, which is not lost with time, but, on the contrary, only increases. Special additives are used to reduce the effect of moisture on the plinth. The disadvantage of this type of plaster can be attributed to more than a modest palette of colors. But it can be easily eliminated by subsequent painting of the base with moisture-resistant materials.
Cement-based plaster mixes are often sold as dry mixes, which, when used, are diluted with plain water, in accordance with the manufacturer's instructions. It is unacceptable to violate the recommendations, because as a result the quality of the resulting surface will deteriorate, and it will be harder to work with such a solution.
If you want to cover your plinth with decorative plaster, then the best option would be acrylic surface. The basis of such plaster is resin, and special fillers give it not only resistance to moisture and temperature extremes, but also allow air to pass through painlessly. Such a surface, among other things, will not be affected by the fungus, it does not grow moldy and resists other microorganisms.
Manufacturers pack acrylic plaster in the form of a ready-made solution, which remains only to be thoroughly mixed before application in accordance with the instructions.
Silicone plaster has quite high price due to high quality indicators and versatility. The composition is based on polymer compounds that provide surfaces effective protection from any negative influences, and give it an attractive appearance on long years.
The surface with silicone particles repels dirt, protects against microorganisms and has a high vapor conductivity. This feature makes silicone plaster indispensable for buildings made of aerated concrete. The composition is very easy to apply to the surface and has a fairly rich color palette, which will allow you to choose any color and even a combination of colors.

Methods for applying plaster on the plinth

There are manual and machine methods of facing the basement using decorative plaster. Manual way does not require the purchase of an expensive tool, and a textured base requires special spatulas and the ability to work with them.
External work with the plinth must be carried out in strict accordance with the technology recommended by the manufacturer, which determines the speed of applying the composition, the time and order of its drying.
In order for the plastering work to go smoothly, it is necessary to do everything in advance preparatory work. To do this, the surface is cleaned of traces of the old coating and dirt, all irregularities are eliminated with the obligatory use of the level. Areas with traces old plaster be sure to peel off, and for better adhesion of the mixture to the surface, you must first apply deep furrows.
Weather conditions certainly affect the quality of work. Strong wind will hinder quality application plaster, and hot weather promote premature drying of the solution during operation. The most favorable air temperature is between 5 and 25 °C. At the same time, the air humidity should not exceed 70%.

Plinth cladding with plaster

Basement plaster has a number of advantages that other materials do not have. Having made the exterior finish of the basement, you will transform your house, it will have a presentable appearance and acquire its own unique personality.

First of all, prepare a set of working tools, consisting of a plastic grater, roller, wide paint brush, trowel, spatula and coarse construction sponge.

Installation of mosaic plaster: step by step instructions

Mosaic plaster is applied not so often, but it is very original and effective. Consider a phased workflow with this method of designing the basement of a house.

It is necessary to prepare the surface of the plinth, namely to level the surface, clean and remove the old coating.
Even stuffed on the surface plaster mesh with dowels wide hats. One m² should be fastened with at least 16, and preferably 20 dowels.
The next step is to measure about 30 cm from the corner of the wall and use screws to mount the plumb lines. We fix the thread strictly vertically on other screws, it turns out, 2 pairs of screws on each wall with a thread stretched between them. We do the same with horizontal threads, and so that they are at least 2 cm from the wall.
Then, along the threads, we expose steel beacons in increments of approximately 2 to 5 m, which we fix with cement mortar and expect it to completely solidify.
We apply a primer on the prepared surface, depending on the material from which the base is made. It is important to choose the mixture that is intended for this material.
Before use, the primer must be diluted with water to a paste-like state. Professional builders recommend to buy ready mix rather than dry primer. In terms of price, the difference is small, but the latter requires less time to complete, with a fairly high quality.
When the main layer dries, you can proceed to decorative works. Plastering the top layer is also best done ready solution, since it is unlikely that it will be possible to achieve the necessary shade of the desired color on its own. It is more practical to use the factory mixture, because you will prepare the solution yourself in small portions, and you are unlikely to be able to achieve a uniform color.
For 1 m² of area, 2.5 to 6 kg of solution is usually needed. Consumption depends on the size of the granules and the method of application. Having calculated the amount of mortar you need, you can start plastering. Applying it to the plinth is easy enough using the wet-on-wet method. Having covered one layer, it is evenly leveled until completely dry, then the second is applied in the same way using a special metal grater.
So that the boundaries of the areas do not stand out on the surface and do not look like separate spots, it is important to level the surface in such a way that the mixture layer is approximately equal to the size of the granules.
In conclusion, it is important to let the plaster dry completely, this will take a couple of days.

Plaster on the grid will ensure the adhesion of the surface of the basement with the solution. For those who are interested in plastering the basement, there are a large number of video tutorials in which step by step it is shown in detail how to correctly and in what sequence this type of work is performed.
Remember that a thick layer of plaster will better protect the plinth, and thermal insulation will be even more effective. It is better to apply the material in two layers, and the finish coat should be treated with a decorative material.
For more durable and resistant processing, reinforcement of the top layer is used, so the plaster will not crack and fall off.
Plastered surfaces are simple repair work, do not require the use of complex equipment, tools and instruments.
Surfaces treated with plaster have a number of disadvantages compared to other types of coatings. When compared with stone, tile or other types of alternative materials, then this material is inferior to them in strength, service life, degree of insulation and it is more permeable to moisture than the above analogues. The processes of thawing and freezing, of course, gradually destroy such a coating, therefore, treat the surface of the base with negative temperatures Not recommended.
To protect the plinth layers, various materials are used; plastering remains the most common and inexpensive today. Using modern technologies, it is possible to achieve that the surface of the base will look like it is lined with natural stone. It is also possible to make an imitation of wood and even metal. Such a surface will be sufficiently durable and resistant to aggressive environments.

Relatively inexpensive and practical protection the foundation is the plastering of the plinth under the stone with your own hands.

The selection of a pattern and color will allow you to create a single architectural ensemble the entire building. At this stage, it is easy to achieve a combination of wall style with the lower chord of the house by using the same materials.

Conditions to be followed

If a finish with a stone pattern is chosen as the outer coating of the plinth, the general requirements for such a coating are observed:

Mechanical strength (important for do-it-yourself installation);
moisture resistance;
Frost resistance;
Biological stability (fungus, mold, microorganisms);
Neutral to ultraviolet.

Based on this, dry ready-made facade mixtures with the specified properties, designed for a large number of weather cycles in a given climate zone. There is another option - the solution for finishing the basement is prepared independently, choosing additives, plasticizers and chemical additives.

If there is a layer of thermal insulation of the foundation of the house from polymer materials, its reliability outdoor protection should not be in doubt. Leakage will result in loss of desired properties and premature failure.

Solution Requirements

A decorative (finishing) layer of a solution prepared by oneself and consisting of:

cement (preferably brand M400 in a ratio of 1/3. M500 - ¼);
sand (quarry, sifted on a fine mesh, washed from clay, organic inclusions);
water (the amount varies until a thick, plastic mass is obtained, convenient for application, leveling, shaping);
additives (plasticizer, hydrophobic component, polymer dispersion. The simplest options can be PVA glue, a small amount of washing powder (increases plasticity);
color, mineral filler in the form stone chips with decorative properties(marble, quartz, granite).

The hardening of the plaster must not be accelerated forcibly (blowing, heating, IR emitters). The main layer dries under the covering film material for 2-3 weeks (depending on the thickness) with regular wetting for the first 4 days. Only after complete drying does the lining of the base begin. The thickness will depend on the depth of the relief cut and ranges from 0.5-1 cm (for shallow impressions) to 2-3 cm (plausible, voluminous masonry).

Stone stitching

The advantage of plaster is that any pattern can be reproduced on a dry solution. The most typical types:

Masonry. Imitates brick, hewn stone of different sizes;
Blocks. Masonry option with larger parts, palace blocks;
Torn bottle. Large/medium/small-sized boulders of various sizes, fitted end-to-end;
Small stone. Many rows of raw small elements;
Pebble. Round small pebble.

Avoid noticeable distortions, unnatural angles of transitions, frequent repetitions, precise fitting of the depicted elements. Also, do not align small roughness and crevices. The transitions of the hillocks into the depressions look more natural than a strict plane, compliance with which is not required when plastering the lower belt of the house.

Creation methods

The process of plastering according to the selected texture with your own hands can be done in two ways:

Stamping. Stencils of several contours are made, which are applied to freshly applied plaster and tapped. The resulting print is embroidered. Rollers are also used for small relief. The decorative pattern is rolled in even rows.
Slotting. The recesses in the solution are made with a sharp tool (a fragment of a sheet of metal, tin, cut under a characteristic groove). The lines are expanded by inserting a metal ruler, tapping until the required clearance and angle are obtained. Complex transitions in the lining can be formed from a notch made with a spatula, with a hand in rubber glove. frozen solution lends itself to the influence of a circular saw, but the figure is already limited. A wide seam requires two cuts with the middle removed.

The plausibility of large details of the image on the decoration of the foundation of the house is achieved in a combined way. A characteristic pattern of the material is applied to the block formed by the slot using an impact metal stamp with protruding parts measuring 15 × 15 cm.

Surface leveling is carried out with a wet grout of plaster, for example, with a canvas mitten. Roughness natural stone created with metal soft brushes.

Treatment

In order for the plinth to be beautiful and reliable for many years, it is not enough just to plaster it. In addition to introducing various additives into the composition of the solution, after the base has dried, etching and waterproofing are carried out. Disinfection of the outer layer is achieved by treatment with an acid suspension. work paint roller, sprayer, with the obligatory use of skin protection, respiratory protection.

After drying, the solution is washed off with water, the drains of which must be diverted from the house into prepared recesses in the ground.

Painting

The most successful color scheme for finishing is the choice of the color of the plinth, which does not contrast with the main tone of the house. Even better, if the shade of the resulting stone looks a little darker, “heavier” than the material of the walls. However, the choice of color depends only on your desire, and the plinth can be painted or plastered:

in one tone (the plaster is not painted or a continuous coating is performed with one composition);
two tones (the stone is different from the seam cutting);
several tones (color transitions imitate real material. This is the most costly, spectacular and time-consuming execution of the foundation finish).

Exploitation

The basement serves as one of the indicators of the state of the foundation of the house, and also plays significant role in his appearance. That is why the decoration of this part of the house should be given special attention. It is also worth noting that all operations for the care, inspection, repair and finishing of the foundation can be done by hand.

The plinth is the lower belt of the facade of the building, which is designed to protect it from mechanical influences and various contaminants. The main rule when finishing is to choose a high-quality and durable coating that will, in without fail, preserve the facade and at the same time, perform a decorative function. Finishing the plinth with mosaic plaster is one of the the best options for your building.

Varieties of mosaic coating

This finishing material nothing more than a tandem of crumbs and resin. Although sometimes it happens that the baby is already painted artificially. This type of plaster shows excellent resistance to changes. weather conditions, including humidity. This very strength is provided by the first component - acrylic resin. It is because of it that the plaster is not susceptible to water, and at the same time allows moisture to evaporate freely. This prevents water from accumulating and leading to negative consequences.

Varieties and benefits

AT construction stores the range of plasters can make you get confused. The main difference between all types of plasters is the size of the crumbs. Depending on the size of the fraction, the material is graded:

with a fine fraction - grains up to 0.5 mm;
medium - 1.2 - 2 mm;
large - 3 mm.

But you can also find plaster with a grain size different sizes, i.e. mixed. Material with a fine fraction can not be used for all types of exterior finishes. Therefore, when making a purchase, you need to check whether it is suitable this species for your work.

Pleasing to the eye of the buyer and numerous colors. Now there is no problem to choose the right color finish.

The advantages of mosaic plaster for the plinth are as follows:

high resistance to various mechanical damage;
does not require special care or cleaning;
a large assortment color solutions;
good decorative qualities.

From theory to practice: the application process

As with any other construction process, you need to know where to start and what comes next. The stronger the layer of mosaic plaster on the plinth, the more reliably it is protected. In order for this to be possible, the prepared mixture is carefully applied only to dry walls. If there is moisture on the walls, its excess will evaporate for a long time. Even taking into account the fact that the mixture is vapor-permeable, it passes moisture much more slowly, which can lead to such negative consequences as, for example, the appearance of moldy fungi on the walls.

The first condition on which the quality and durability of the coating will depend is preliminary preparation buildings and correct application mosaic plaster for the plinth.

The first step is to level the surface of the base, removing small elements such as fragments, dirt or plaque. Also, most manufacturers advise to prime the base after cleaning and preferably with a “deep penetration” agent. This will help strengthen the base and regulate the plinth's ability to absorb moisture.

After the previous steps are completed, the surface is leveled. For these purposes, you can use the leveling mass.

Firms offer a variety of primers that are turned into the most popular colors - white, sand, brick, graphite. This is optimal choice, because they make it possible to create a uniform color of the plaster layer without differences, and through which the nondescript building base is not visible.

Basic application rules

This material is already sold as a mixture in plastic buckets or containers. Immediately before use, their contents should be mixed very carefully. A mixer is ideal for this procedure. As with many other products, this happens, some products from different batches with differences in production on the same day may differ. This is due to the fact that natural mineral chips are used in the production, so individual batches may differ in color. When purchasing several packages, it is advisable to pay attention to serial number, which will show whether these goods were produced in the same batch. If the mass was produced on different days or even months, in order to protect yourself from color differences in the plaster, all the purchased mass must be poured into one large container and mixed thoroughly.

The resulting mixture must be used in accordance with the conditions and rules that are indicated in the technical data sheet of the product. It is better to carefully monitor that the process is uninterrupted. You also need to constantly ensure that the fresh mass, already applied to the walls, in no case comes into contact with the one that has dried - this is where the complexity of the application lies. Otherwise, the place of their joints and connections will be noticeable.

Application process

The prepared and well-mixed mixture is applied to the plinth in small strips, on average no more than 1 meter wide. Two methods are used for this: manually or by spraying. Manually, the mass is applied using a tool such as a trowel, often made of stainless steel. After application, the strips are smoothed so that there are no gaps between the grains of the plaster.

Experts advise to act in the same direction during the application process so that the entire layer of plaster looks uniform. Another rule when working with decorative plaster is that it should never be overwritten.

With manual application Such a coating can often be handled even by a not particularly qualified specialist. What is there to say about experienced craftsmen. But the spraying method is best left to knowledgeable builders.

After the application process is completed, and your house already boasts a strip of decorative plaster, you need to protect the fresh layers from heating in the sun and strong gusts of wind. This is especially true on the first day. The layer also should not have a point of contact with the ground. Otherwise, pollution in these areas cannot be avoided. In the worst case, capillary traction of water can occur, which will adversely affect freshly applied layers of mosaic plaster.

with a value of 0.5 - 1 mm, it takes about 2-3 kg;
with a size of 1 - 1.5 mm, 3 - 4 kg are consumed;
with dimensions of 1.5 - 2 mm - 4 - 5.5 kg;
with a grain size of 2 - 3 mm, a consumption of 5 - 7.5 kg should be planned.

There are a few more little tricks when working with mosaic plaster:

If it is applied to metal surfaces, they, in turn, must be well cleaned of corrosion;
If, when preparing surfaces that are covered with sufficiently old paints, or putty material using drying oil, it is necessary to cover the entire section of the wall with an insulating agent. This will avoid different color projections.
The application of a primer is a fundamental and necessary step in this process. The entire surface must be uniform in color. color scheme walls, without any unpainted areas and very well dried.

Optimal conditions for soil drying are temperatures from 20 to 22 degrees Celsius and air humidity in the range of 60-70% for at least 24 hours.

Restrictions when working with mosaic plaster:

surface humidity can be maximum 10%;
minimal allowable temperature for work - 5 degrees Celsius above zero;
