Mineral plaster for interiors. Mineral plaster for facades. Mineral plaster: what is it

Modern mineral plaster is, first of all, a variety of relief surfaces with original compositions: pebble products, “bark beetle”, “liquid wallpaper”. Many types of raw materials are used to create them. To choose the right material, you must first study the properties and characteristics of building materials. This will help to avoid unnecessary financial costs and get a solid surface.

In the old days, the main function plaster mortar consisted in leveling the walls and ceilings inside the premises for the subsequent application of other, thinner, coatings on it. On the facade of the houses, plaster was used to protect the surface from the effects of adverse atmospheric factors. Today, the situation has changed radically, and the status of dry mixes has increased significantly.

The vast majority of building materials contain natural substances that allow us to talk about environmental safety. finishing coatings. This is especially important when it comes to the arrangement of premises. Therefore, mineral plaster for interior work is based on an aqueous mixture of slaked lime - lime hydrate. It does not pose the slightest danger to human health after applying it to the walls.

The main binding component is white Portland cement. As fillers, marble chips or other natural stone of small fractions can be added. Most often used cheap and ubiquitous quartz sand. In some brands of plaster make various kinds modifiers used to enhance the durability of the composition and color. Since these substances are made with the addition of chemical additives, most of them form mineral plaster for facades.

Advantages and disadvantages of products

All plaster mixes have distinct advantages over other types of coatings. In addition to the environmental friendliness mentioned above, these include high level resistance to mechanical impact. The strength of the composition is such that it must be beaten with a hammer or special tool. Plaster is not afraid of moisture. Even after a direct hit of rain, snow, it does not get wet and does not lose its properties. Excellent steam conductivity allows the walls to "breathe" without forming dampness and the main enemies of health - mold and fungus.

mineral plaster not afraid of changes in air temperature. This is especially true for the outer parts of buildings. And, importantly, it is completely safe in terms of fire, since there are no elements of ignition in the material. The product requires easy care. The interior mortar can be painted, cleaned and wiped with a damp cloth. The surface is not damaged. The lack of material concerns the application technology. If the rules are not followed, cracks may appear. Eliminating the defect is very simple in the process. But even with its presence, the mixture will last a long time, without additional repairs.

Varieties of mineral plasters

In addition to conventional cement, gypsum or lime mortars, designed special and decorative designs. The first include shielding, sound and heat insulating means. Decorative are of several types:

  • colored;
  • terrazite;
  • pebble;
  • Venetian;
  • sgrafitto;
  • silk.

Mineral facade plaster is also produced. Each of all the listed materials has certain properties that ensure the quality of its use in certain conditions. The differences between them are significant. key factor when choosing is resistance to the influence of the external environment.

The mixture for apartments has an attractive appearance, but is not suitable for outdoor coating. On appearance facade solutions are rough. Without aggressive components, they can be used for interior decoration of technical warehouses, non-residential and utility rooms. The product in the form of a pebble structure is formed by a large number fine grained granules. The effect of the stone is achieved by laying the mortar in a circular motion of the tool, in this case half a terre. The composition of the “bark beetle” mixture is almost identical to the pebble one and differs in a smaller amount of granular filler. Application technology is different. The movements of the grater should not be rotational, but strictly in one plane - horizontal or vertical.

Mineral decorative plaster"Terrazite" is a mixture of white Portland cement, fluff, filler and dyes. Used mainly for exterior finish walls. It is applied in two stages: first, a leveling primer, and then a colored top coat. The Venetian mineral mixture has been known since ancient rome and the Renaissance. Its structure contains fine dust from natural stones, slaked lime, V modern version- Polymer acrylic. This type is used exclusively for interior improvement. The finer the size of the filler granules, the more smooth surface walls will work. The technology of applying Venetian plaster is laborious and involves the formation of 3 to 10 layers. The complexity of production is such that not every master can cope with the “Venetian”.

"Silk" products

Otherwise, this material cannot be called a miracle. It includes fillers made of cellulose, silk threads and adhesive. among the people this product called liquid wallpaper, as it is applied instead of them, surpassing the latter in all respects. This type plasters are especially convenient to use in hard-to-reach and relief places. It will hide all the irregularities of the wall without difficulty.

The coating is not afraid of moisture and has a unique feature. If cracks appear due to non-compliance with the technology or shrinkage of the foundation of the house, the disturbed surface is treated with water from a pulverizer and rubbed with a grater. From the flaws will not remain a trace. The service life of the product is up to 8 years. Any other plaster, not to mention wallpaper, will not stand such a test. Color " liquid wallpaper” impregnates the entire thickness of the layer, and not just outer surface, so they have a very high resistance to fading.

The product can be used in any premises, except for places where direct contact with liquid is possible: bathtubs, sinks for washing hands or utensils in the kitchen. But here there is a way out: the plastered surface is varnished on water based. The material does not absorb odors, is absolutely universal and environmentally safe. Its application, as in the case of the “Venetian”, should be handled by a highly qualified specialist. When choosing an expensive product, you should pay attention to the brand of the manufacturer. Today, a huge number of counterfeit products are found on the market, so the seller must require a quality certificate.

Finishing work, both external and internal, is increasingly carried out using decorative plasters. For them, gypsum, cement, sand, lime, acrylic, crushed minerals are used. Mineral facade plaster is found in different compositions.

It includes particles:

  • Granite.
  • Marble chips.
  • Lime.
  • Light cement.

Note. These components give it high quality as a decorative finish.

A significant advantage of materials is their fast adhesion:

  • Mineral plaster surpasses analogues in the strength of the connection with the bases.
  • It dries in 1-2 days, and surface hardening occurs in the first 20 minutes, so you need to work with it very quickly.
  • The composition is applied in 1 layer, without corrections. If this is done in several steps, then sagging and thickening on the wall are obtained.
  • The work will be ruined.
  • Mineral decorative plaster is a durable and strong material.
  • It retains its impeccable appearance for several years. Wall decoration will be durable, which means that you do not need to spend money and effort on new work.
  • The porous structure of the surface partially absorbs moisture, which further strengthens the structure of the composition.

In the photo you can see the design interior design using mineral plaster:

This type of finish is distinguished by good heat and sound insulation, it passes air well, does not become damp and is not subject to the formation of fungal plaque.

Working with drywall

Especially often, decorative mineral plaster is used on drywall:

  • This is a perfectly flat surface on which the mixture fits well.
  • This type of decoration is used to decorate individual elements of the wall - niches, cornices.
  • It gives the appearance of the room a natural rough style, which is now fashionable.
  • Inner walls can additionally be varnished to give. shine and longer life.

In this case, you will have to make cosmetic repairs less often.

Outdoor use

Due to its properties of resistance to moisture and temperature changes, mineral decorative plaster is widely used to decorate the exterior facades of buildings:

  • This is a durable and beautiful wall decorationthat will last for many years.
  • With the help of plaster on minerals, individual elements of the facades are singled out, or the entire surface is completely covered.

Note. The composition is not subject to fire, therefore, for fire-fighting purposes, it is good for them to finish walls and partitions made of flammable materials - drywall, chipboard, wood.

Mineral plasters have a rough surface with visible particles of mineral chips:

  • They are used for decorative purposes only.
  • Mixtures are applied to a leveled surface with eliminated differences in convexity, with disguised dents and crevices.
  • If the wall is not carefully prepared, the flaws on it will be even more visible.

A thin layer of mineral mixture cannot close them up.

Application for finishing

Usually decorative mineral plaster is used for finishing walls:

  • Its unusual texture creates original style, does not require additional coverage with wallpaper or paint, is stored on for a long time and does not require maintenance.
  • This is a practical and safe design. internal walls children's institutions and public buildings. In residential premises, mineral coating is used less frequently.

At the request of the customer, such a surface can be coated with matte paint or varnish:

  • Add to the mixture coloring compositions or use natural color.
  • A thin layer of mineral mixture gives an unusual look to a pre-painted wall.
  • It is preserved, but the color of the wall is somewhat muted and softened.
  • Mineral inclusions ennoble the surface.
  • If it is additionally coated with a transparent varnish, then original color walls will shine through even brighter.
  • Depending on the type of filler, plaster can be textured, rough or smooth.
  • There are pebble, silky or grooved finishes.

Note. For many years, builders have been using facade plaster, which is called "fur coat". It is laid out in regular geometric medallions or let in a strip along the perimeter of the house.

How to make mineral plaster yourself

With some skills in construction business you can try to finish the wall with your own hands without involving a specialist. The coating technique is not much different from conventional plastering.

Advice. Protective clothing should be prepared, as contact with the skin is undesirable.

Necessary materials and tools for work:

  • When using a dry workpiece, it is necessary to have containers for mixing the composition with water.
  • Mixer for preparing a uniform solution.
  • Spatulas of different lengths and widths (see Construction spatula - types and differences).
  • Steel grater (for applying the composition).
  • Trowel.
  • Soft plate for creating a texture pattern.
  • beacons, adhesive tape, angular profiles.
  • Reinforcing mesh.

Application instructions:

  • First, the walls are leveled with rough plaster.
  • Eliminate dents, traces of dowels, cracks and roughness.
  • Particular attention should be paid to the clear shape of the corners.
  • After the initial layer has completely dried, the wall is sanded with medium-sized emery and degreased.

Stage one

It is done in this way - soft thermal insulation material be sure to reinforce with reinforcing mesh:

  • The initial plaster is then applied to it.
  • For good adhesion of the compositions, the wall is primed before the finish coating.
  • Before starting work, it is necessary to calculate the amount of solution, since it is not stored and is applied in one layer.
  • You need to know how much of it is required per 1 m2.

Advice. Tools should be moistened with water during operation. If you bought ready-made plaster in the store, and it turned out to be very dense, you need to dilute it with water and mix thoroughly.

Stage two

The heterogeneous mass will drain. The consistency should be such that the solution adheres well to the spatula, but is soft. If the plaster is applied in a pattern, the edges of each element are glued masking tape so that there is a clear border of color.

The mixture is applied with vertical movements, the angle between the spatula and the surface is no more than 15 degrees:

  • First, a layer is applied with arbitrary movements, then it is leveled thinly and evenly.
  • The thickness of the coating should not exceed the size of the filler particles. Profiles are fixed in the corners and the boundaries of the joints are aligned with a mixture.
  • Soft plaster allows you to apply any pattern or relief on a wet surface.
  • This is done using a plastic grater with the desired pattern.

Note. For example, to get the “Bark beetle” relief, circular or vertically horizontal movements are made with a plastic plate, leaving thin grooves.

Stage three

The adhesive tape is removed 15 minutes after applying the solution:

  • On large areas coatings use an electric unit to apply the solution to the wall.
  • But alignment is done manually. With this method, the finishing time is significantly reduced, but the rapid solidification of the mortar requires masterful precise alignment.
  • The facade of the building plastered from the outside must be protected from dust and debris during the drying of the mortar. You can stretch a film or a fine mesh on it.

The video in this article will help you visualize the process of preparing and executing wall decoration.

Types of mixture

According to the type of structure, 3 types of finishes can be distinguished:

Lamb (pebble) A large inclusion of small granules gives a resemblance to sheep's wool. The mixture is applied exclusively in circular motions of the semi-terre.
Mineral plaster "Bark beetle" It has a lower content of filler elements and is applied in more straight lines.
The application method "Fur coat" is more often used for outdoor work But if a fine-grained solution is used, then such a finish is also suitable for interior spaces. A flat tool is applied to an even layer of the applied mixture and pulled back with a sharp movement. Acute-angled tubercles are obtained on the surface, similar to wet fur.
Venetian plaster Imitates marble coating.
wet silk Brilliant finish and the use of mica chips.

Solution consumption rates

It is necessary to take into account the size of the filler fraction:

  • The larger it is, the thicker the layer of plaster will be.
  • On the packaging of the finished store mix, this figure is slightly underestimated.
  • That is, it is necessary to purchase material with a small margin.

The table shows the consumption rates of plaster:

In conclusion: areas of application

In the apartment, you can decorate the walls with a rough texture in the hallway or bathroom. This coating is not afraid of moisture. On the building materials market, you can find a wide variety of dry and ready-mixed mineral plasters.

Note. One of them is decorative minerix plaster. This material is manufactured by Gelster.

Minerix decorative plaster is used for facade works for paint application:

  • Its feature is the possibility of decorating the outer insulation layer.
  • The basis for the mineral finish is a reinforcing adhesive. The final layer is applied to a flat, smooth wall.
  • Mineriks decorative plaster is also used on concrete, cement bases.
  • They are treated with a primer 2 times. The mixture is prepared in the usual way - by mixing 25 kg of dry powder and 5-5.5 liters of water.

Mineral stone plaster imitates a natural stone tuff, limestone. It is used for outdoor work, and is applied in a thicker layer of 100 mm. After the solution has completely hardened, the impact tool forms the texture of the stone coating.

Mineral plaster - natural, environmentally friendly pure material, which is a dry building mix, which is used for both internal and external works.

The composition of mineral plaster and its application

Mineral plaster is made on the basis of lime hydrate, marble granulate, white high-quality Portland cements and light mineral aggregates. Such plaster is very economical in terms of costs and is well suited for the thermal insulation of a building. Although the composition of the plaster contains lime, which does not tolerate water, the material itself can be safely cleaned and washed, since it contains substances that prevent the lime from “melting”.

The material is intended for both interior design and facade work. By the way, during facade work, plaster is often used in the system of external thermal insulation. Mineral decorative plaster is not picky in work and can be applied on any mineral bases, including gypsum plasters, asbetocement, plywood, fiberboard, chipboard, concrete and drywall. But still, the mixture is best suited for walls that are prone to abrasion or have a protruding surface (entrances, stairwells, corridors, etc.) as well as for the basement of buildings.

Photos of works made with mineral plaster
Mineral decorative plaster: advantages
  • environmentally friendly material;
  • high resistance to mechanical damage and precipitation;
  • resistance to temperature difference and frost resistance;
  • allows the walls to "breathe";
  • fireproof;
  • ease of care (any detergent can be used for cleaning).

Mineral plaster application technique

  1. The surface must be thoroughly cleaned, leveled and dried.
  2. Next, you need to clean the surface of old finishing materials. Removing each of the materials has its own difficulties. Read more about the whole process. After that, it is necessary to prime the defective areas on the surface.
  3. We are waiting for the wall to dry. After that, you can start applying the material.
  4. According to the instructions on the package, it is necessary to dilute the dry solution with water following the recommendations indicated.
  5. Next, you need to process the entire wall without interruption, from corner to corner. At the corners and joints, it is best to use masking tape, it will allow you to get a flat surface. It is necessary to read in advance in the instructions how many layers are recommended to be applied. The quantity may vary depending on the manufacturer. The material is not used at temperatures below 5 ° C. The material dries within 3 days.

Mineral plaster is an environmentally friendly finishing material, which consists exclusively of natural ingredients. Suitable mineral plaster for interior and external works. It is inexpensive, economical and easy to operate and operate. But before buying such material, you need to find out which mineral mixtures are now most in demand.

Application area

Mineral decorative plaster is a composition based on granite and marble granules, hydrated lime, anthracite, crushed quartz, mica, glass, colored clay, ceramic balls, white Portland cement and lightweight aggregates. Sold dry mix in bags. It must be diluted with water just before use, referring to the instructions on the package.

The mixture is applied with a trowel or an ordinary spatula, there is nothing complicated in the application process: a novice master can handle it. But when processing large area it is desirable to use a mechanized application method. If a layer with a thickness of more than two centimeters is applied, then the presence of a reinforced mesh is mandatory. After drying, the mortar forms a porous, durable, non-combustible layer with excellent sound and thermal insulation. This finish will require a mandatory finish from the master, as it is badly affected by climatic influences.

IN ready mix additives are present which increase the moisture resistance of the coating. Vapor permeability is maintained. Due to this, such a coating prevents the formation of fungi. Such plaster performs two functions at once: practical and decorative. At the same time, it is an additional heat-insulating layer.

Plaster does not tolerate stress and vibration, so you should not use it until the building has completely shrunk, when finishing houses that are located close to railway or in a turbulent seismic zone.

Mineral plaster allows you to perform different textures on the wall, the most popular are:

  • bark beetle;
  • travertino;
  • grooves;
  • fur coat;
  • lamb.

Coarse-fraction mixtures are usually used for facade work, decorating certain elements in the home interior. Mineral fine-grained plaster is more convenient to use compared to coarse-grained plaster. The texture can be applied with a brush, roller and even improvised materials if the roller is not at hand.

Is in great demand fine-grained mineral plaster. It contains marble chips. It is with its help that a luxurious Venetian coating is created under a polished stone. decorative effect created by a special application technique: small strokes and very thin layer. In addition, each layer needs to be sanded and ironed. The Venetian coating in the interior is wonderfully combined with stone, wood, and modern materials.

For interior work, it is not advised to take mixtures that contain glass, mica, anthracite, since dust from these substances can be harmful to human health. For interior decoration, it is better to choose materials with quartz or marble chips.

On average for square meter it takes four kilograms of the mixture, but in practice the figure is significantly different. Consumption will directly depend on the granularity of the solution, the quality working surface. The larger the fractions, the thicker the layer will be, therefore, more solution will need to be used.

Comparison with competing blends

In the construction market, you can find not only mineral plaster, but also silicate, silicone, acrylic. It is worth noting that they are more expensive than the considered option. Therefore, it is worth comparing their characteristics in order to understand what mineral compositions advantages over competing finishing materials, in addition to the lower cost:

Application technology

Protective equipment is used for work. The composition has an alkaline pH, therefore it is necessary to protect open areas skin . From the materials for work you will need:

  • mixing containers;
  • construction mixer;
  • spatulas different sizes;
  • steel grater for applying the solution;
  • plastic grater to create texture;
  • trowel.

In addition to the above, masking tape, beacons, corner profiles, plaster mesh may be required.

First, the walls, in the presence of obvious defects in the form of crooked bends, recesses and holes, are leveled with the help of starting compositions. Even cracks should not be left on the surface. After this preparation, there will be a surplus cement mortar, you will also need to get rid of them with the help of grinding tools, for example, sandpaper medium hardness. If there are stains, the wall is additionally degreased.

If the plaster is produced according to mineral wool insulation or any other soft base, laying a paint grid is required. It is attached to the prepared base, the starting plaster mixture is applied on top.

Before applying the finishing solution, the wall is primed to improve adhesion. After that, the tools are wetted with water - so the composition will not stick, and it will be much more convenient to work.

The calculation of the amount of composition to cover a certain composition is calculated in advance. Excess solution after drying will not be suitable for further use.

If you buy ready-made plaster, and it does not have a very convenient consistency for application, then it can be diluted tap water mixing thoroughly until smooth. With a heterogeneous mass will not work quality coverage: There will be untidy smudges that impair the appearance of the surface. The consistency of thick sour cream is considered optimal for application.

If you want to create geometric pattern or combination different colors, then masking tape is applied along the marked or drawn lines. The solution itself can be applied both from the bottom up and from the top down. The angle between the tool and the wall is fifteen degrees. First, a rough layer is applied, then it is leveled with a spatula. Then profiles are applied to the corners, pressed, covered building mix and align.

If the wall is covered with a bark beetle, then the next stage of work will be the creation of an invoice. It can be created with a plastic grater in linear or circular motions - it all depends on what result is required. Then there is a technological pause of twenty minutes. It is needed for the initial setting. Then the masking tape is removed. After the final hardening, varnish can be applied to the surface. Usually the plaster hardens in a day, but it all depends on the purchased belly. The packaging should indicate the exact setting time.

The composition can be applied with special electrical equipment, but the alignment is still done manually. If the composition is used with outside At home, the treated surface will need to be protected from wind and street debris during the drying time.

Mineral plaster in the interior

For interior finishes mineral plaster is more often used in hotels and office buildings. But for home interior she fits too. Most often it is taken to decorate the hallway or bathroom. Stone options are well suited for the bathroom, plaster does not lend itself to the formation of fungus and mold, and is not afraid of moisture. It beautifully imitates coarse sand.

For the hallway or corridor, the popular option "Bark beetle" is suitable. With this option, it is worth playing up the color of the plaster additional accessories. But in everything you need to know the measure: the abundance of details will make the space of the room overloaded.

With the help of the structural composition, it is not necessary to process the room completely. You can select only a specific wall, or desired area, for example, the fireplace area in the living room.

average cost

Pebble plaster will cost more than the one created on the basis of cement. The cost of one package of 25 kilograms will vary depending on the specific brand. Other factors also affect the cost of finishing material:

For example, a bag of Ceresit mixture is sold at an average price of 550-850 rubles, "Teplon" - 450-500 rubles, and "Chrysel" will cost an average of 400 rubles. But the price difference can be quite serious. At Vetonit, the price varies from 600 to 2500 rubles.

If you follow all the rules for applying mineral plaster to the surface, safety precautions and acquire high-quality Decoration Materials, then the resulting finish will last a long time without losing its aesthetics and without cracking.

Finishing is an integral part of construction and repair work. Usually putty is used as a finish. They may be different. There are silicate, silicone, acrylic, gypsum, cement-lime, cement-sand options. But recently, decorative mineral plaster has become very often used. Its composition includes minerals different origin(granite or crushed marble). Also in the composition there is a light grade of Portland cement and lime. What are the features of this plaster and what is the technology of its application? We will consider all this further.

What are the advantages of the material?

Among the pluses in the reviews is the rapid setting of the material. Compared to analogues, decorative mineral plaster quickly connects to the base. During the day, it solidifies completely (and the initial drying occurs already at the 20th minute). But since all reactions occur quickly, it is also necessary to work with this material without delay. Otherwise, a quality result will not work. If decorative mineral plaster is applied according to the instructions, then you can get a durable and aesthetic wall surface. This is possible due to the porous structure of the material. Under the influence of moisture, strength increases. In addition, the material passes air and performs a heat-insulating function.

Use for interior work

Very often, mineral decorative plaster (including bark beetle) is used for interior work with drywall. Additional processing it is not required, and plaster can change its texture. Often it is used to highlight some objects. These are niches, cornices, and sometimes separate walls. Thanks to mineral plaster, you can give the coating a rougher look. If this interior work, additionally the surface can be varnished. This makes the color of the wall more saturated and gives the coating more gloss. In addition, the strength characteristics are increased.

outdoor work

Since this plaster perfectly withstands moisture and other atmospheric influences, it is often used for facade work. As practice shows, such coatings serve for a long time. The composition withstands very coldy and frequent temperature fluctuations. You can take care of such a coating with any detergent composition. Decorative mineral plaster is used for finishing:

  • Outdoor stairs.
  • Inputs.
  • Socles.

It can cover both a separate element of the house and the entire facade. The material is not combustible, so it can be used as a protection for wood, chipboard or MDF panels.

Use for decorative work

This plaster is also used for decorative purposes. It does not need additional coating with tiles or wallpaper. At the same time, it looks quite stylish and modern. Composition for decorative works can be either tinted or not. Sometimes it is applied already on the painted surface. If you apply a thin layer of the composition, the color of the base will remain. And you can achieve the desired depth of shade with a colorless varnish. It makes the wall look more attractive. The texture of the plaster may be different, depending on the type used. So, the composition can be silky, with grooves or pebbles.

Primary draft work

Is such a composition used for rough work? Experts give a negative answer. Mineral plaster is an exclusively decorative and finishing material. Therefore, it cannot be used as a starting plaster. The composition is applied only on the prepared surface, without large drops and with masked cracks. Otherwise, all the defects on the wall will be visible.

Varieties

There are two types of this plaster:

  • Structural.
  • Textured.

Structural is distinguished by the presence of fractions different section. At the same time, it acquires texture after being applied to the surface.

Structural plasterers include pebble (it is also mosaic). It consists of fine granite or marble with the addition of other components. Very often, bark beetle plaster is used for finishing. She refers to textured type. After application, you can get voluminous and beautiful drawing. A slightly different effect is obtained after using Venetian mineral plaster. Small fractions of various shades and colors are visible on the surface (as a rule, this is marble dust). Contains no additives rocks. Venetian plaster includes marble chips and natural ingredients (cellulose).

What is needed for application?

Many are interested in how decorative mineral plaster is applied. To carry out this work, you need to prepare the means personal protection. It is unacceptable for the composition to get on the skin, as it has an alkaline pH. From the tools you will need:

  • The grid is plaster. Its price is about 120 rubles per meter.
  • A container for mixing the mixture (if not ready-made, but dry is used).
  • Grater for plaster (steel).
  • Trowel.
  • Spatulas (several pieces of different sizes).
  • Construction mixer and plastic grater.

We will also need:

  • corner profiles.
  • Lighthouses.
  • Masking tape.

Getting Started

So, first you need to level the walls with starting putty. This is used to seal holes, recesses, crooked bends and crevices. All defects must be eliminated in advance.

After preparation, particles of cement mortar may remain on the surface. You need to get rid of them too. This can be done using sandpaper. Additionally, the wall is degreased in the presence of stains. If you are finishing on a soft base (for example, on a heater made of mineral wool), you need to lay a special plaster mesh grid (its price is about 150 rubles per running meter). It is laid on the base, and the starting plaster mixture is placed on top.

Before applying the finishing composition, this wall is primed. This is necessary for better adhesion. To prevent the composition from sticking to the tool, the latter is pre-wetted in water. Then you can get to work. It is important to pre-calculate desired composition, as it must be applied in one go. If there is an excess of the mixture, in the future it will be unusable, as it will quickly dry out.

If store bought ready composition turned out to be too dry, it can be diluted with plain water. By mixing the composition, you can get the mixture that is ideal in consistency. But putty should not be too liquid. Ideally, the composition should have the consistency of sour cream.

If it is necessary to apply any geometric pattern to the wall, or to produce a combination of colors, masking tape is applied to the surface along the marked lines. The solution is placed top-down and bottom-up. There should be an angle of 15 degrees between the tool and the wall. It is important that the layer is thin and does not exceed the thickness of the largest fraction of the putty composition.

First, a rough layer is applied, and then leveled with a spatula. Further, the profile is laid on the corners and pressed. After that, the corner is also covered with a putty mixture and leveled.

If the bark beetle putty is used, the next step is to create an invoice. This is done with a plastic trowel for plaster. It is necessary to make linear or circular movements. Then they stop work for 20 minutes. This is necessary in order for the initial setting to occur. Then it is removed with raw residues. After that, you need to wait another two days and boldly varnish the surface. It is advisable to apply the composition using electrical equipment. The wall dries at the same time without additional influences - it is enough to open the windows. If work is being done outdoors, it is important that debris does not accumulate on the surface.

Consumption

Consumption depends on the grain diameter of the largest fraction. How larger size, the thicker the layer (respectively, the greater the consumption of the composition). For example, the consumption of Lamb plaster, where the cross section of the granule is about 2.5 millimeters, is 3.5 kilograms per square meter. And if the size of the granule is 3.5 millimeters, this consumption increases by 1.4 kilograms.

Price

It should be borne in mind that decorative mineral plaster will always be more expensive than ordinary cement plaster. The cost will depend on:

  • The composition of the mixture.
  • Varieties.
  • Mixture type.
  • Sales points.
  • region of production.

It is worth considering that mineral decorative is much more expensive than conventional cement-based. The price for a pack of 25 kg varies even within one specific brand and depends on a number of factors, including:

  • Sales points.
  • Mixture type.
  • Categories/grades.
  • region of production.
  • The composition of the mixture.

Ceresit mineral decorative plaster will cost from 600 to 840 rubles on average. This is the price for a 25 kg bag. The price of the "Krysel" composition is slightly lower than the "Ceresit" plasters - about 450 rubles. But the composition of "Vetonit" can cost up to 2.5 thousand rubles. It is believed that Ceresit plaster is the golden mean.

Conclusion

So, we found out what mineral decorative plaster is. With this mixture, you can significantly change the design of the interior or facade of the building. However, so that the result does not upset, you need to know the application technology.
