How to make warm plaster with your own hands. Warm plaster for interior use. Step-by-step instructions for making a solution

The choice of insulation for interior wall decoration is a task that has many solutions today. At the same time, many prefer known materialssuch as foam or rock wool.

However, there is a less traditional method of warming, which has not yet gained special popularity due to high cost of the composition... We are talking about a material called "warm plaster", the features of which will be presented for consideration in this article.

What is this material?

Thermal insulation plaster -a combined material that combines ordinary rough plaster and insulation components.

Mineral additives contained in the mixture, give the solution heat-insulating properties... Warm plaster contains the following types of fillers:

• porous (expanded polystyrene granules, perlite, foamed glass, etc.);
• astringent components (cement, gypsum, lime);
• polymer materials - plasticizers.

Heat insulating plaster - highly porous material, due to which it is sometimes called "drying".

Varieties

Depending on the filler, which gives the composition thermal insulation qualities, warm plaster is divided into several types, each of which has its own characteristics.

With perlite

Perlite is a material based on expanded perlite sand. It is a type of volcanic glass and has a texture similar to pearls, but contains more than 1% water in its composition.

The feature of the material is ability to increase (5-20 times) and swelling (10-12 times) as a result of heat treatment. Perlite plaster is used for facade decoration and interior walls, both in industrial and residential premises.

Perlite mix advantages:

• high heat and sound insulation properties;
• high-quality adhesion when applied to various mineral surfaces;
• the plaster is fireproof and gives additional fire resistance to the treated surface;
• has good vapor permeability;
• environmentally friendly and harmless to health;
• differs in flexibility and ease of use.

The downside is high gyroscopicity, that is, the ability to absorb moisture four times its weight, which is why the surface needs a finish.

Do-it-yourself warm plaster for interior work

The walls need to be prepared cleaning them from dust and dirt and removing the old coating (wallpaper, tiles, paint, etc.).

For better adhesion the surface can be impregnated with a primer deep penetration. The honeycomb structure, as well as the presence of reinforcing fibers in the composition, make the warm plaster resistant to cracking, so that the surface to be finished does not need to be reinforced.

Before applying the composition the walls should be thoroughly moistened warm water for high-quality adhesion of the solution to the surface.

Next you need knead the solution with an electric drill and a mixer, following the instructions on the packaging. You can check the readiness of the composition by typing the mixture on a spatula and turning it over. If the solution does not fall, then it is ready for application.

The application process itself is the same as finishing with conventional cement mortar. Beacons are installed on the wall between which they throw the mixture and level it with the rule. The layer thickness is usually no more than 5 cm.

For applying the final leveling layer a thinner solution should be used, which is smoothed with a plastic float, thereby eliminating minor defects, pits and irregularities. After 48 hours, the plastered surface can be tiled.

Applying warm plaster: video instruction.

Plaster intended for facade works, must meet the criteria for quality, strength, durability.

Exterior plaster is popular precisely because of its high quality indicators.

In addition, facing materials of this type have a long service life, are produced in a wide range, and also withstand natural influences well.

There are different textured options ("", "lamb"), has a different composition (,), and also has certain functions (decorative, heat-insulating). To increase the thermal insulation of the walls, warm plaster is used.

The basis of this type facade plaster is dry mix, which includes various plasticizers, glue, cement sand. The main substance in the composition of this material is hollow substances (granular expanded polystyrene, foam glass particles, sawdust), due to which the plaster has thermal insulation properties.

Plasticizers help to maintain the elasticity of the material and resistance to temperature extremes, and prevent cracking.

The polymers included in the mixture contribute to mechanical resistance.

Insulation of the facade with a plaster mixture

Warm facade mixture is much lighter than conventional facing mixtures, but when several layers are applied, its weight increases significantly, therefore the foundation must be additionally reinforced... Like any other material, warm plaster has its own advantages and disadvantages.

Advantages

The main advantage of this facing material are thermal insulation qualities. The composition helps to retain the heat of the walls and prevents cold air from entering the room.

In addition, warm plaster:

• easy and quick to apply;
• does not require the use of reinforcing mesh, which reduces costs;
• does not require wall alignment;
• has good adhesion properties to any surface;
• no cold bridges are formed during coating;
• prevents the appearance of rodents;
• the main composition of the mixture is of natural origin;
• frost-resistant;
• has vapor-proof properties;
• waterproof;
• has sound insulation properties;
• is an environmentally friendly material.

In addition, the facing mixture is durable and does not require special maintenance. Thanks to insulation with such a composition, it is possible to reduce the thickness of the insulation.

Sectional device

disadvantages

The main disadvantage of insulating plaster is additional design: after application, the surface should be primed and then decorative.

In addition, the total weight of the material after application is quite significant.

The cost of warm plaster, which does not require additional coating, is quite high.

Areas of application of warm plaster

Insulated plaster is used not only for decorating the facade of a building, it can also be used:

• for the purpose of sealing cracks;
• for insulation of building walls;
• when sealing floor joints, as well as for warming floors and ceilings;
• for the purpose of insulating the basement of the building;
• at registration window slopes, doorways;
• for insulation of sewer risers of cold and hot water supply.

In addition, this mixture is used not only for outdoor decoration, but also for internal works.

Types of warm plaster

Warm plaster is classified according to the composition of the mixture. Thus, it is customary to divide the material into types:

• with the content of granular polystyrene foam. Suitable option for facade and outdoor work;
• with sawdust content... This type includes paper, cement, clay. It is advisable to use such a mixture for interior work;
• containing vermiculite (or perlite)... This mixture has good antiseptic properties and is optimal for outdoor use.

If a binder in warm plaster is gypsum, then this mixture is only suitable for interior work.

For external (as well as for internal) work, the most suitable is a mixture, the main component of which is cement.

Preparatory work

Before applying warm plaster to the walls, they should be prepared for work.

This requires:

• remove protruding elements in the wall: pieces of reinforcement, brick or concrete protrusions;
• if there was an old coating on the wall (paint, putty), it should be removed;
• if there is insulating material or sand in the panel joints, everything must be cleaned;
• if there are cracks in the wall, they must be sealed with a sealant;
• degrease and clean the wall surface from dust;
• treat the wall with a primer.

NOTE!

In order for the adhesion of the mortar to the base to be high, it is recommended to apply the mixture in a thin layer (3 to 5 mm) after the primer has dried.

Complete drying is achieved after 24 hours in dry weather, then you can start applying the main layers of the putty mixture.

Mixture consumption

The consumption of the facing mixture per 1 m² is indicated on the packaging of the material.

Depending on how thick the layer is laid, the amount of material required is determined:

• with a layer thickness of 2.5 cm, the material consumption will be 10 - 14 kg per m²;
• with a layer thickness of 5 cm, the material consumption will be 18 - 25 kg per m².

In addition to material consumption, you can determine its cost per 1 m².

The effectiveness of sound insulation is achieved with a warm layer thickness of 0.5 cm... However, the thermal insulation mixture is more often used as insulation, and fibrous materials are recommended for sound suppression.

Do-it-yourself warm plaster technology

For facing work on the facade, you should choose warm, low wind, dry weather.

The solution should be mixed immediately before application: in the proportion indicated by the manufacturer, dissolve the dry mixture in a large container, mix for several minutes. Then wait about ten minutes and mix the composition again to obtain its homogeneity.

The prepared mixture retains its properties up to four hours.

Warm mix

The solution is applied as follows:

• beacons should be installed at a distance of 50 cm to obtain an even layer;
• it is advisable to first apply the solution with a small spatula, then with a large one. The mixture is applied from the bottom up. After covering a meter - one and a half walls, the applied solution should be aligned with the rule;
• the excess removed by the rule can be reused;
• beacons should be removed after coating, the holes from them should be sealed with mortar and the surface should be leveled.

Despite the plasticity of warm plaster, the thick layer can crack. The recommended layer thickness is two centimeters, so the mixture will not slide down. Each layer is applied on top of the completely dried previous one, therefore it will take a sufficient amount of time to complete the coating in several layers.

Reinforcement

If, nevertheless, the thickness of the first layer is 4 cm or more, it is necessary to consistently continue work:

• the first layer is covered with a reinforcing mesh two hours after its application;
• apply a thin layer of the mixture to the arm net and profile with a notched trowel;
• after 24-48 hours, apply the second layer of the solution in the same way as the first.

As practice shows, a layer of 5 centimeters is enough for the result to meet the requirements. This layer has thermal insulation and other properties inherent in this type of coating.

If the need arises, after the cladding has completely dried, it is decorated with additional materials (,). You can decorate the surface, ceramic tiles, granite chips and other decorative facing materials.

Before using them, the dried surface of warm plaster should be coated with a primer solution.

Alignment

Thus, warm plaster is not only an external coating that protects the facade, but also an additional heat-insulating material that can reliably insulate the walls of a building. At the same time, it is possible to reduce the cost of the layer of the main insulation, as well as decorate the walls with an additional decorative coating.

It is not difficult to carry out work on applying warm plaster. Besides, given view the coating fits well to any walls, does not require additional leveling.

In contact with

As soon as the composition of the usual one was slightly changed, a completely new material - warm plaster. Manufacturers attribute unique qualities to it and claim that the material can be used as an independent one. So what is it, true or just another clever marketing ploy? How to choose the right warm plaster for the facade and interior work, how to apply it, and in what cases can the material really be used as a full-fledged heat insulator?

# 1. Warm plaster composition

Warm plaster was named for its low thermal conductivity compared to conventional plasters. Similar results were achieved by replacing the usual with special heat-insulating additives.

The composition of warm plaster includes such components:

Usually the material is supplied as a dry mix, and it is enough to dilute it with water before application. Craftsmen prepare warm plaster on their own, but the composition "works" in any case according to one principle: thermal insulation additives, together with air bubbles, create a powerful barrier to cold. Tests show that a layer of warm plaster of 5 cm is equivalent in thermal insulation to a wall of two.

The coefficient of thermal conductivity of the material is about 0.063 W / m * 0 C. This indicator is slightly worse than that of extruded polystyrene foam and even, which brings some features to its application. In regions with cold winters, warm plaster cannot be used as an independent thermal insulation - it is usually applied as an additional layer of insulation and plays an important role in eliminating the "cold bridges" that arise during the installation of tile and roll insulation. In areas with mild winters, warm plaster can even be used as the only thermal insulation material, but much depends on the thickness and material of the walls. In the future, we will check all this by calculations.

# 2. Advantages and disadvantages of warm plaster

Warm plaster has become widespread due to its weighty advantages:

Now about disadvantages:

Number 3. Types of warm plaster fillers

The type of filler greatly affects the properties and scope of use of warm plaster. The following materials can be used:

• sawdust... The composition of sawdust warm plaster, in addition to the sawdust itself, also includes clay, paper and cement. Using so "gentle" and sensitive to negative factors external environment components does not allow the use of the composition for insulating the facade, but such warm plaster is excellent for interior work, especially since it can even be applied to wooden base... Internal thermal insulation will improve efficiency;
• crushed perlite is obtained from obsidian, which swells during high-temperature processing with the formation of a mass of air bubbles inside, which increases the thermal insulation properties of the material. The only drawback is increased hygroscopicity, so such a plaster needs reliable waterproofing;
• expanded vermiculite obtained from mica, the material can withstand a wide range of temperatures, has antiseptic properties, is lightweight, absolutely resistant to fire, can be used for external and internal decoration, but, like perlite, it is afraid of moisture, therefore, requires enhanced protection;
  
• balls from foam glass obtained from foamed quartz sand. It is the most preferable material for filling warm plaster, as it is not afraid of moisture, fire, has good thermal insulation qualities, can be used for facade and interior work, does not shrink;
• as mineral fillers, in addition to vermiculite, perlite and foam glass, are also used expanded clay chips and pumice powder... These materials cannot boast of high moisture resistance and are inferior to analogues in many other qualities, therefore they are rarely used;
• expanded polystyrene used in warm plasters together with cement, lime and some other additives. These are relatively inexpensive compounds for universal use, but due to the flammability of expanded polystyrene, they are not used so often. In addition, the surface of the plaster comes out too soft, and therefore requires mandatory finishing.
  

No. 4. Calculation of the thickness of the layer of warm plaster

To determine whether it is possible to use warm plaster as an independent insulation, you will have to perform a simple calculation, taking into account the region where the house is located, the thickness and material of the walls:

• the calculation begins with determining the value normalized resistance to heat transfer of the outer walls of the house... This is a tabular value, predetermined by regulatory documents (for Russia - SNiP 23-02-2003). For Moscow, according to the table, this value is 3.28 m 2 * 0 C / W, for Krasnodar - 2.44 m 2 * 0 C / W;
• define resistance to heat transfer of the walls of the house, for which we need to divide the wall thickness by the coefficient of thermal conductivity of the material. Let's make a calculation for two houses. One is located in Moscow and is built of, the thickness of the walls is 0.5 m, the coefficient of thermal conductivity from the table is 0.58 W / m 0 С, therefore the heat transfer resistance is 0.86 m 2 * 0 С / W. The second house is located in Krasnodar and is built from D600, the wall thickness is 0.4 m, the thermal conductivity coefficient from the table is 0.22 W / m 0 C, the heat transfer resistance is 1.82 m 2 * 0 C / W;
• payment additional insulation... For a house in Moscow, this is (3.28-0.86) \u003d 2.42 W / m 0 C. For a house in Krasnodar (2.44-1.82) \u003d 0.62 W / m 0 C;
• payment a layer of warm plaster, its thermal conductivity coefficient is 0.063 W / m * 0 С (maybe a little more, depending on the composition and manufacturer). For a house in Moscow 0.063 * 2.42 \u003d 0.15 m, for a house in Krasnodar 0.063 * 0.62 \u003d 0.04 m.Since it is better not to apply warm plaster with a layer of more than 5 cm, and its weight is decent, then for a Moscow house, it is better to look for another option for insulation, and warm plaster can be used in addition. For a home in Krasnodar, warm plaster can be used as an independent insulation.

A more accurate calculation can be carried out if we take into account the resistance to heat transfer of all finishing wall materials, and also take into account the number and size of windows and the mass of other parameters. It is easier to do this in special construction calculators, but you can already understand whether it is worth considering warm plaster as an independent insulation from the above calculation.

Despite the manufacturer's assurances and calculations proving the effectiveness of warm plaster, it is not very often used as the main insulation in residential buildings. She usually, dachas, is used to eliminate cold bridges, to process window and door openings. It is better to use insulation outside, but if this is not possible, it can also be applied inside to complement the external insulation.

No. 5. Warm plaster manufacturers

You can save and make warm plaster with your own hands... The most versatile and inexpensive solution is obtained using perlite or vermiculite. It is necessary to mix 4 parts of vermiculite or perlite and 1 part of dry cement. The thoroughly mixed mixture is diluted with a solution of water with a plasticizer. The latter can be purchased at the store, or can be replaced with PVA glue at the rate of 50-60 g of glue per 10 liters of plaster. The mixture is diluted with a water-based adhesive and constantly stirred for homogeneity. The solution should have a thick consistency. After cooking, he is allowed to brew for 15-20 minutes, and you can start applying the plaster.

No. 7. Applying warm plaster

The process of applying warm plaster is simple and easy to do with your own hands:

• preparing required amount solution;
• the wall is also cleaned for better adhesion, but many builders simply moisten the surface with plain water;
• it is better to carry out the plaster on the lighthouses, although some neglect this rule. As beacons, an aluminum profile is used, which is fixed with putty, the use of prepared plaster is allowed. The evenness of the exposed beacons is checked by the building level;
  
• modern ready-made compositions of warm plasters make it possible to do without additional mesh reinforcement, but when applying a thick layer of insulation and at the corners, using a mesh is desirable;
• the process of applying warm plaster is not original and identical. The solution is put on the trowel with a spatula, after which it is applied to the wall with rubbing movements from bottom to top between the beacons. The surface is leveled by the rule;
  
• within 2 hours after application, the solution remains plastic, so blemishes can be easily corrected. During this period, beacons are removed, the cracks are rubbed with the same solution. If desired, the surface can be treated with a decorative trowel or structured roller to achieve an interesting effect. If a flat surface is required, then after the plaster has dried, it is necessary to apply a thin leveling layer and smooth it with a plastic float;
  
• the thickness of one layer should not be more than 2 cm, otherwise the plaster will begin to fall off. If it is necessary to apply it in several layers, then after installing the first one, you must wait at least 4 hours. The surface dries completely after 48 hours, then you can proceed to its final finishing. If it is necessary to process a large area of \u200b\u200bthe wall, then it is better to use the machine method of applying plaster.

Warm plaster is used today for, for outside and inside, for insulating facades and ceiling slabs, as well as for sealing cracks and cracks, for processing window slopes. When correct preparation, application and calculation, the composition fully meets expectations.

Warm dry compositions for interior decoration today are considered one of the most popular products on the building materials market. The reason for this success lies in the fact that such materials can achieve excellent thermal insulation properties. They are used for cladding and restoration of old buildings, as well as for thermal insulation and protection of new construction projects. Warm plasters for wall cladding inside the house are in special demand. The reason for the demand is associated with ease of use. You do not need to drill something for dowels, you should not use complex plastering systems. All that is needed is simply to find an experienced specialist to carry out the interior decoration.

Characteristic

Before deciding on the choice of dry plaster for interior decoration, it is necessary to consider criteria such as advantages, disadvantages, properties and types of material.

The article describes such a building material as well as other data characterizing this material.

Warm plasters are classified into the following types:

1. Perlite based... Such a material is characterized by such a disadvantage as the accumulation of moisture. As a result, the thermal insulation properties of the material are reduced. Over time, cracks will appear on the facade. If not take additional measuresthen it will simply collapse. But there is such a plus as the excellent sanitation of the wall, as a result of which all the moisture is literally sucked onto the surface of the wall. Provided that measures were immediately taken to hydrophobize and ventilate the steam, the coating will continue to serve for sanitation and thermal insulation for a long time.
2. Based on expanded polystyrene... assure that as a result it is possible to obtain warm plaster, but completely non-ecological, not fireproof. Another disadvantage is considered to be poor vapor permeability.
3. Based on foam glass balls... This is presented in the form of granules that are not sorted. They do not concentrate moisture in themselves, therefore they conduct steam well. This filler is characterized by high fire resistance, thermal conductivity, strength and durability. Today, this option of warm plaster is considered the most popular.

As for the advantages of warm plaster, the following can be distinguished:

• high tenacity with different kind surfaces, while the walls do not need to be leveled;
• there is no need to use metal fasteners, since there are no cold bridges;
• high rates of sound insulation and tightness;
• ease of application and fast installation time;
• resistance to fungi and mold;
• natural vapor permeability;
• additional protection of walls from seasonal changes in temperature indicators.

You can find out about that for a bag by reading the article.

Installation of warm mixes for interior decoration does not differ from the application of ordinary plaster. The mixture is used for various purposes: for leveling, thermal insulation, restoration of buildings. If you have purchased a completely different composition, then you should definitely grab the warm plaster, which you will need to process the internal slopes.

They produce certain brands of heat mixtures that need additional waterproofing and can be used as a topcoat.

When planning to carry out repair work in the room, you should think over and take into account all the details, because in such work there can be no trifles. Warming a room is one of the most important processes and should not be ignored. Warm plaster is one of the options for solving this issue.

Features:

Many residents of apartments and private houses hear about warm plaster for the first time, so you should understand in more detail what it is, for what purposes it is used and what its varieties are.

All construction Materials have certain thermal insulation properties. Using ordinary plaster, you can only slightly insulate the room. To achieve stronger insulation, use warm plaster.

When applying warm plaster to the surface, the wall is smoother, while its thermal insulation increases.

Use this material in construction and when performing renovation works started not so long ago, so few know about the composition and properties of warm plaster.

With its help you can:

• align the wall;
• decorate the surface;
• provide a temperature for a comfortable stay.

In addition, this material has a soundproofing function.

Thermal insulation materials have a porous, fibrous or cellular structure that is filled with air, gas or vacuum. When applied to the surface, a kind of "fur coat" is created.

Since ancient times, natural materials have been used for wall insulation. For this, straw, sawdust and clay were used. By coating the walls with a mixture of these materials, diluted with water, they achieved their insulation. Perhaps this technique is still used somewhere in the villages because of its cheapness and ease of use.

Modern technologies do not stand still, and today a large number of materials are produced that are used for wall insulation. The warm plaster is based on various fillers and binding components, as well as other additional ingredients.

The filler for warm plaster can consist of different materials. Consider their description and characteristics:

1. The filler may contain expanded polystyrene... This material has a high level of thermal insulation, moreover, it is inexpensive. In addition to the undoubted advantages, polystyrene foam has a disadvantage - it can quickly ignite, and toxic substances are released during the combustion of the material.
2. The cheapest, besides, the most environmentally friendly material can be called sawdust... They are often used when self-production material, although sawdust does not have high heat-shielding properties.
3. Perlite.When processing perlite high temperature get a material with a porous structure. Perlite has good resistance to temperature extremes and is easy to work with. It also has resistance to harmful microorganisms.
4. The material that is made from mica is vermiculite... It is very durable, has a high level of hygroscopicity, has biological safety and fire safety.
5. Foam glass.For its production, they take quartz sand. This material is recommended for use in rooms with high humidity, which is undoubtedly its advantage. Its thermal insulation properties are lower than those described above.

Plaster or cement is used to bond these materials. Using cement in work allows you to achieve a more durable surface. The mortar with cement has grey colour, from the outside it will be noticeable. In order to get rid of the gray tint on the surface, it can be covered with a gypsum putty.

Instead of cement, you can take gypsum. Usually it is used only indoors.

Specifications

You need to figure out where warm plaster is used, how easy it is to apply to the surface indoors.

So, this material is applicable for:

• for leveling walls and creating additional thermal insulation;
• filling of voids, insulation of water pipes, sewers;
• insulating the slopes of windows and doors - such an insulating surface will prevent the ingress of cold air and drafts;
• often heat-saving putty is applied when insulating a ceiling or floor.

Heat insulating putty has many advantages:

1. First of all, it should be noted that it is easy to work with this material, plus everything at once can be solved with both insulation and surface finishing.
2. The material has excellent properties and high adhesion to many surfaces.
3. When working with a warm putty, priming of the surface is often unnecessary.
4. When applying the solution to the surface during operation, no seams or so-called "cold bridges" remain on it.
5. Using modern plasters, you can not be afraid that over time the material may be spoiled by insects or eaten by rodents, moreover, pathogenic bacteria will not breed in it.

If the composition consists of gypsum, perlite and vermiculite, it is not recommended to use it for internal insulation rooms with high humidity, since these materials are highly hygroscopic.

Before starting work, you need to prepare the walls. The surface should be cleaned from the previous layer and remove hooks, nails and other small partsthat can interfere with work. Next, the walls should be primed and left for a couple of days to dry completely, and only then carry out the work on warming the premises.

Considering all the advantages of the material and its disadvantages, we can say that the use of warm plaster indoors is quite justified. It is used in combination with other heaters, but it should be applied in places where it is really needed.

• In order to prepare a solution, take 1 kg of the mixture and 0.5 liters of water. The composition is not recommended to be made in large portions.as it dries very quickly. For mixing, take a construction mixer and stir until the mixture looks like sour cream.
• When mixing a dry mixture with water, pour the liquid in a littlestirring constantly. When using a moisture-resistant composition, it is enough to take 200 liters of water for 1 kg of the mixture. Before starting work, the solution is left for a few minutes to soak.
• When applying putty, take a trowel with a rule.The layer should not be made thick, it should not exceed 5 cm. When applying the material to the ceiling, the layer size should be reduced to 3 cm. By applying putty on the walls, you can immediately level the surface and remove minor defects.

• After covering the entire surface, waituntil the wall is dry. This can take a little over an hour. After that, it is pruned using the rule. You can take a building level to check. At this stage, possible disadvantages such as cavities, irregularities and roughness are eliminated.
• If the walls remain uneven after applying one layer, they are left to dry and then reapplied with another layer. If more than one layer is applied, after the surface has completely dried, it is primed and sewn up with a reinforcing mesh.
• At the final stage, glossing or glazing is done.To do this, the surface is moistened with water and cleaned with a spongy float. When cement or gypsum milk appears, rub the wall with a soft wide spatula. You can leave the wall in this form, it no longer lets heat through, but more often it is painted with facade paint, sewn up with siding, or any other decorative work is used.

High-temperature putty is an easy-to-use material that is used for interior work. When choosing this material, it should be borne in mind that the mixtures are quite expensive, and for work you often have to buy several packages.

To avoid additional waste, you can use a putty prepared by yourself. Homemade solutions absolutely not inferior in quality to store options.

As part of our own production putty:

• one piece of sand;
• one part of cement;
• four parts of perlite / vermiculite;
• the required amount of water for the mixture to become creamy.

When making a solution with expanded polystyrene, vermiculite and perlite, the ratio should be 1: 4, that is, if you take 0.5 kg of sand and cement, you should add 2 cubic meters of perlite and about 500-600 liters of water.

Sometimes PVA glue is added to this composition, but it is not used in large quantities - it is enough to take 2% of the total amount of water. When adding glue to the solution, it must be diluted beforehand. Instead of glue, you can take a plasticizer, for example, polyplast.

For self-preparation of the putty, you will have to experiment a little in proportions.It is not recommended to knead a lot of solution at once, it is better to make small portions. When applying them to the wall, it will immediately become clear how correctly the proportion was chosen and whether the material is convenient for use.

If perlite or vermiculite is used for cooking, a large amount of liquid must be added. If there is not enough water, the solution will harden immediately and will be unusable.

For internal work, it is better to knead masonry mortars on plaster.

Manufacturers

One of the most popular companies that produce putties is the company Knauf... This name is known to many and deserves to pay attention to the products of this company. The composition of this plaster contains cement with polystyrene, as well as special additives.

When the solution is applied to the surface, a strong structural layer is formed. Once dry, you can use textured paintsto decorate the surface. Apply a layer of plaster from 10 to 30 mm, you can work with your hands or by machine... Available in 25 kg packages. When applying a minimum layer of 10 mm per 1 sq. m you need to take about 12 kg.

When using this putty indoors, it should be borne in mind that it contains polystyrene, which has a high degree of flammability. Knauf putties are used both outdoors and indoors.

By choosing quality material for indoor use, you should pay attention to thermal insulation plaster "Umka"... Russian manufacturers were able to make a dry mix that has excellent characteristics. The composition was developed taking into account the harsh climate.

After applying the solution to the surface, finishing is usually carried out finishing work... The dry mix is \u200b\u200bpacked in 7 kg packages. When applying a minimum layer of 10 mm, take 4 kg of the mixture per 1 sq. m.

A dry mixture is also used to insulate walls indoors. "Bear"... A layer of this mixture of 2 cm in terms of its thermal conductivity will be equal to brickwork 50 cm. Before applying the mixture "Bear" to the wall, the surface is leveled and primed. They produce a mixture for wall insulation indoors in bags weighing 14 kg.

Other most popular dry mix companies include:

• Unis;
• Paladium;
• ThermoUm.
