Warm plaster for interior work with your own hands. What is warm plaster and how is it applied?


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

Plaster for exterior decoration is popular precisely because of its improved quality indicators.

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

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

The basis of this type of facade plaster is a dry mixture, which contains various plasticizers, glue, cement sand. The main substance in the composition of this material is hollow substances (granulated polystyrene foam, foam glass particles, sawdust), thanks to which the plaster has thermal insulating properties.

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

The polymers included in the mixture contribute to resistance to mechanical stress.

Insulation of the facade with plaster mixture

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

Advantages

The main advantage of this facing material are thermal insulation qualities. The composition helps 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 use reinforcing mesh, which reduces costs;
  • does not require wall leveling;
  • 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-tight properties;
  • waterproof;
  • has soundproofing properties;
  • is an environmentally friendly material.

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

Sectional view of the device

Flaws

The main disadvantage of heat-insulating plaster is the additional design: After applying it, the surface should be coated with a primer, and then a decorative coating should be applied.

Besides, total mass The material after application has quite a significant weight.

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 to decorate the façade 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 insulating floors and ceilings;
  • for the purpose of insulating the basement of the building;
  • upon registration window slopes, doorways;
  • for insulation of sewer risers for cold and hot water supply.

In addition, this mixture is used not only for exterior decoration, but also for interior works.

Types of warm plaster

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

  • containing granulated polystyrene foam. Suitable option for facade and exterior works;
  • containing sawdust impurities. The composition of this type includes paper, cement, clay. It is advisable to use this mixture for interior work;
  • containing vermiculite (or perlite). This mixture has good antiseptic properties and is optimal for external use.

If the binding component in the composition of warm plaster is gypsum, then this mixture is suitable only for interior work.

For exterior (as well as interior) work, the most suitable mixture is the main component of which is cement.

Preparatory work

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

To do this you need:

  • 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 need to be sealed with sealant;
  • degrease and clean the wall surface from dust;
  • treat the wall with primer liquid.

PLEASE NOTE!

In order to ensure high adhesion of the solution to the base, it is recommended to apply a thin layer (from 3 to 5 mm) of the mixture after the primer has dried.

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

Mixture consumption

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

Depending on the thickness of the layer, 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 the material consumption, you can determine its cost per 1 m².

Effective sound insulation is achieved with a warm layer thickness of 0.5 cm. However, thermal insulation mixture is more often used as insulation, and it is recommended to use fibrous materials to suppress sound.

Do-it-yourself technology for applying warm plaster

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 specified by the manufacturer, dissolve the dry mixture in a large container and stir 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 mixture

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 bottom to top. After covering a meter - one and a half walls, the applied solution should be aligned with a rule;
  • the surplus removed by the rule can be reused;
  • After applying the coating, the beacons should be removed, the holes from them should be sealed with mortar and the surface leveled.

Despite the plasticity of warm plaster, a thick layer can crack. The recommended layer thickness is two centimeters: this way the mixture will not slide down. Each layer is applied on the completely dried previous one, so 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 continue the work sequentially:

  • The first layer is covered with a reinforcing mesh two hours after its application;
  • Apply the mixture in a thin layer to the reinforced mesh and profile with a notched trowel;
  • after 24-48 hours, apply a second layer of 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 to this type of coating.

If the need arises, after complete drying facing covering 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, capable of reliably insulating the walls of a building. At the same time, it is possible to reduce the cost of the main insulation layer, as well as decorate the walls with an additional decorative coating.

Carrying out work on applying warm plaster will not be special labor. Besides, this type The coating fits well on any walls and does not require additional leveling.

Applying warm plaster with your own hands:

Warm plaster for interior work is an innovative product in the field of thermal insulation of premises.

This type of material is used for finishing facades and rooms. Some manufacturers also offer universal mixtures.

The composition of the solutions differs and depends on the scope of application and the required properties.

What is warm plaster? Its composition

This type of finishing material has recently appeared on the markets. Warm plaster combines thermal insulation and leveling properties.

New building material made on the basis of cement or gypsum with the addition of additional elements:

  • foam glass or foamed silicon;
  • pumice powder;
  • sawdust;
  • perlite;
  • foamed vermiculite;
  • granulated polystyrene foam.

Gypsum warm plaster is suitable for leveling walls and ceilings in interior spaces. Cement compositions are used for both interior and exterior work.

The characteristics and properties of the additives are described in the table below.

Material Properties
Sawdust Environmentally friendly material. One of the most affordable in price segment. You can mix warm plaster yourself with sawdust. Low level of thermal insulation.
Foam glass Made from quartz sand. Suitable for use in rooms with high humidity. Low thermal insulation.
Vermiculite The basis for the production of the material is mica. Fireproof, not afraid of fungi and resistant to mechanical damage. The only drawback is that it absorbs moisture well.
Expanded polystyrene Low cost. Disadvantage: it is flammable and releases toxins when burned. High level thermal insulation.
Perlite Environmentally friendly volcanic glass material. Perlite mixtures are easy to process and install. It is fire resistant and prevents the spread of germs and bacteria. High level of thermal insulation.

The market today offers thermal insulation types of mixtures from different manufacturers. Among domestic solutions, they prefer Mishka, Umka UB-21, and Teplon solutions. Imported compounds are much more expensive, but they also differ in quality. Craftsmen pay attention to warm plaster for interior work Knauf Grundband. It is more often used to level the facade, but the cement base allows you to plaster the interior as well.

Advantages and disadvantages of thermal insulation compounds

Mixtures of this type have gained the favor of masters due to a number of undeniable advantages:

  • high level of adhesion to any materials, including wood and drywall;
  • good sound insulation;
  • the material can be used as insulation to prevent the appearance of cold bridges, and also as an independent thermal insulation composition;
  • the mixtures are environmentally friendly, with the exception of those containing polystyrene foam;
  • the weight of the composition is much less than conventional plasters;
  • mixtures with the addition of perlite, vermiculite and foam glass have a high fire resistance class, and warm plasters with polystyrene foam are prone to internal combustion when exposed to high external temperatures;
  • easy to apply because the main binders are gypsum or cement;
  • the layer of warm plaster has high strength;
  • the mixtures are resistant to frost, temperature changes, mold, fungi and rodents.

Despite the impressive list of advantages, such compositions also have a number of negative characteristics:

  • the need to reinforce the surface when applying a layer thicker than 2.5-3 cm;
  • high weight if plaster is used as insulation;
  • low moisture resistance, which requires surface treatment decorative materials with additional moisture protection;
  • Heat-insulating plasters, of course, help retain heat, but they should not be treated like other insulation materials.

Review of mixture manufacturers

Paladium Palaplaster-207 - sound and heat insulating plaster. Most often, this type of mixture is used as a rough ball for painting or wallpapering. The main binding element is cement, and the additive is foam glass. The solution is ready for decorative finishing 3-4 days after application to the surface.

ThermoUm is a universal warm plaster for finishing works indoors and outdoors. The mixture will completely harden within 28 days, after which it will be suitable for finishing. Long service life is achieved by the ability of the material to repel moisture accumulated between the wall and the mortar ball.

UMKA UB-21 is suitable for outdoor use as it can withstand more than 30 freezing cycles. The thermal insulation mixture is made on the basis of lime and cement interspersed with foam glass granules. When installing reinforcing mesh, the thickness of this type of coating can reach 10 cm. After complete drying, the plaster needs finishing.

DeLux Teplolux - warm plaster with the addition granulated foam glass. The composition is based on cement, which makes the mixture universal. After drying, the surface can be painted or decorated with any finishing materials. The period for complete hardening of the coating is 28 days.

Knauf Grönband is one of the most popular thermal insulation solutions among craftsmen. Warm plaster for interior work Knauf - is produced on the basis of cement, therefore it is also suitable for facade work. The filler in this mixture is polystyrene foam. After drying, the layer becomes textured and moisture resistant. Plaster can be painted. The solution is applied with a special machine or manually. The price of warm plaster for interior work of the Knauf brand is quite high, but justified by the properties and characteristics of the material.

Making warm plaster yourself

Since the cost of professional thermal insulation mixtures is quite high, many craftsmen prefer to mix warm plaster for interior work with their own hands.

Step-by-step guide to preparing the mixture yourself:

  1. In a bucket or construction trough you need to mix sand (1 part), cement (3 parts), porous additives (4 parts), discussed above, and a plasticizer. As the latter, it is allowed to use PVA glue at the rate of 50-60 g per 10 liters of mixture.
  2. The entire solution must be thoroughly mixed with water using a mixer.
  3. The consistency of the mixture should be like thick sour cream or semolina porridge. If the plaster is thicker than necessary, add water, if thinner - cement-sand mixture and porous additives.
  4. After the last mixing, the solution must be allowed to brew for 15-20 minutes.

Warm plaster application technology

Important! First of all, you need to take care of temperature conditions in the room where heat-insulating plaster will be applied. Operating temperature from +5 to +25 ℃.

Next, you need to remove the old plaster solution, finishing and dust from the surface that will be plastered. Before applying the heat-insulating mixture, the wall must be primed. This will improve the adhesion of the material to the base.

After the primer has dried, warm plaster is mixed. It is important to use it within 2 hours after mixing, because after that it loses its properties.

To achieve an even application, you should use special beacons and pull the plaster along them.

Using a spatula, trowel and rule, the first layer of plaster is applied. Its thickness should not be more than 20 mm. The next ball can be applied after 4 hours.

The next day, the evenness must be checked using the rule. If there are gaps, they need to be leveled. Next, the surface is sanded using sandpaper and abrasives with different fractions.

After 3-4 weeks, if there are no defects, decorative finishing can be applied to the wall.

When leveling a large area of ​​walls, it is better to use a machine method of applying warm plaster.

For insulating walls from the inside without loss usable area It is optimal to use warm plaster in the room. It is effective for both external and internal work. In cases where it is necessary to insulate a wall in an apartment, this method is ideal.

Types of plaster compositions

The composition of traditional plaster includes:

  • Binder (cement, gypsum);
  • Fine filler (sand);
  • Water.

For thermal insulation interior walls a classic solution can be used, but it will have to be applied in a thick layer of up to 10 cm. To obtain a more effective result, the sand filler is partially or completely replaced with components that can better retain heat:

  • Shredded foam;
  • Vermiculite (granular material obtained by firing hydrated mica);
  • Perlite (mineral of volcanic origin).

A layer of plaster with these fillers at the same thickness will give a greater effect than using a traditional mortar, and by reducing the layer, you can get the optimal heat transfer effect of the wall.

Ready plaster compositions for internal thermal insulation they are produced mainly on perlite. It has a relatively small bulk density- 200…400 kg/m3. It is slightly less for vermiculite - about 100 kg/m3. Perlite is used more often due to its low cost.

Both cement and gypsum can be used as a binder for insulating walls with warm plaster from the inside. In the first case, the wall will be stronger, but will require more careful cladding, since the cement is gray, you will have to heavily cover the color, for example, with gypsum putty. Gypsum is suitable only for interior work; it itself has low thermal conductivity, which further enhances the thermal insulation effect.

Advantages and disadvantages of warm plasters

The advantages, of course, include:

  • Low thermal conductivity;
  • Sufficient layer strength;
  • Small application thickness (no more than 5 cm);
  • No reinforcement required during application.

The main disadvantage of the coating, which must be taken into account, is the high hygroscopicity of mineral heat-insulating plasters. Gypsum, perlite and vermiculite are porous materials that can absorb significant amounts of water. Basic recommendations on this matter:

  • In wet rooms (bathrooms, showers), enhanced waterproofing of the wall is required. Moisture-resistant putties and ceramic cladding are suitable for this.
  • In corridors, kitchens and rooms it is enough to maintain normal humidity of no more than 60%. For additional protection use a deep penetration primer under wallpaper or decorative plasters.

Slaked lime will also help reduce the hygroscopicity of the composition. It does not affect the thermal conductivity of the layer in any way, but it noticeably reduces moisture absorption and improves the plasticity of the solution.

How to make warm plaster with your own hands

The cost of ready-made mixtures is high; it is much cheaper to make the preparation yourself. This way you can save a lot, especially if you need to insulate all the walls in a house or apartment. An additional bonus of large volumes of work is high (total) material consumption, i.e. It is unlikely that you will be left with half a bag of unnecessary cement if you immediately calculate everything correctly and buy the right amount of components.

What you will need:

  • Cement grade M150-M200. This one is inexpensive - about 150-250 rubles per 50 kg bag;
  • Perlite (M75-M100) costs about 100 rubles per 50 kg;
  • Vermiculite will cost more - about 450-500 rubles per 50 kg;
  • Slaked lime- approximately 120 rubles for 20 kg;
  • Washed construction sand - 100 rubles per 50 kg;
  • Water - from the tap according to the meter.

Cooking technology:

  1. The first step is to take the required amount of water. It should be at room temperature.
  2. Dry ingredients can be mixed in advance.
  3. The dry mixture is added to the water in portions; each addition must be thoroughly mixed. construction mixer or a drill with the same attachment. A whisk can be purchased at any hardware and construction store.

How to make warm plaster yourself: recipes

Components should be purchased based on the selected composition.

  • 1) Simple composition: cement, sand and perlite are taken in a ratio of 1:1:4, the mixture is mixed the right amount water until the working consistency of thick sour cream.
  • 2) For a large volume of work, you can prepare a solution from 190 kg of cement, 1 m3 of perlite or vermiculite, 270 liters of water. The volume should be divided into equal parts before mixing, since the finished solution sets within 2-3 hours.
  • 3) A solution with a plasticizer is prepared from 1 part cement, 4 parts perlite, 0.9 parts water; 1 m3 of perlite will require 4-5 liters of PVA glue, which acts as a plasticizer. PVA should be diluted in water, which will be used to mix the mixture.
  • 4) Sand-perlite mortar is prepared from 1 part cement, 2 parts sand, 3 parts perlite. The amount of glue should be 1/100 of the amount of cement, i.e. for 100 kg of binder 1 kg of glue. The mixture is mixed with water until it works.
  • 5) Cement and perlite in a ratio of 1:4 are mixed with water and PVA in an amount of glue of 1% by weight of the binder.
  • 6) Cement-lime mortar with insulating granules is prepared in the proportions: lime - 1 part, cement - 1 part, perlite sand - up to 5 parts. This plaster is perfect for wet rooms.

Solutions based on gypsum binder are prepared in a similar way without the use of glue.

PVA glue can be replaced with liquid soap, dishwashing detergent or specialized superplasticizers that are sold in construction stores. The latter should be used according to the instructions.

Warm plaster based on perlite is low in cost; this filler can be replaced with more expensive vermiculite, then the weight of the layer will be lighter, and the effectiveness of the coating will noticeably improve. Cheap polystyrene foam in granules can also replace perlite, but the thermal conductivity of the plaster will not increase. The only caveat is that polystyrene can evaporate harmful substances when heated significantly, which is why it is rarely used for residential premises. This does not mean that it is prohibited for use; on the contrary, for cool rooms and walls where there is no heating from the sun, this filler will be a good ingredient.

Review of popular warm mixtures

If collecting the components yourself confuses you, you can always purchase a ready-made mixture in the store. It is important here not to run into fake and low-quality material. To avoid such troubles, carefully read the information on the packaging; it always indicates the characteristics of the composition, method and place of application.

To make your choice easier, here are the 5 most popular dry mixes for preparing warm plaster.

Knauf Grünband

The German brand offers a mixture for preparing warm plaster based on cement and polystyrene granules. The material is suitable for interior and exterior work; the solution fits well on any base made of brick, concrete, stone, or building blocks. Any cladding can be applied to the surface: tiles, plastering with decorative materials, wallpapering, etc. To increase adhesion efficiency, the manufacturer recommends treating the surface with deep penetration primer on the appropriate material before applying the solution.

Price plaster mixture Knakf Grunband - about 360-400 rubles per 25 kg bag.

Warm plaster "Mishka" was developed in Russia and is ideally adapted to the local climate. The coating does not allow water to pass through and has low thermal conductivity. A layer thickness of 2 cm is equivalent brick wall 50 cm! The plaster is suitable for interior and facade work.

Modern plaster based on cement and foam glass has excellent characteristics on thermal conductivity and moisture resistance. Suitable for outdoor and internal use. For effective protection against cold and noise, a layer of 5...40 mm is enough. The solution is lightweight and does not require a strong foundation or special preparation. Can be applied to uneven but cleaned and primed surfaces of brick, all types of concrete and stone. Does not retain moisture and has breathable properties.

For effective material you will have to pay about 680 rubles per 12 kg bag.

Warm plasters of the ThermoUm series from the company " Green house» have excellent sanitizing parameters, low rate thermal conductivity, do not retain moisture, can be applied to any substrate. The products have been tested in European laboratories and have appropriate quality certificates. Produced and supplied to order.

UNIS Teplon

UNIS Teplon gypsum-based mixture - light warm plaster for interior work. Perfectly adapts to any type of surface, suitable for use in dry and wet areas. The layer thickness to achieve insulation parameters is 5…50 mm, depending on the characteristics of the main wall. The main advantages of the composition are the absence of shrinkage and ease of application.

You can buy a gypsum-based UNIS Teplon mixture for 375 rubles (30 kg).

Technology of insulating walls with warm plaster from the inside

Wall insulation with inside The standard layout of the premises looks like this:

  • 1) The surface is cleaned of old decoration;
  • 2) A primer is applied with a deep penetration compound;
  • 3) The first layer of plaster is applied. If a thick coating is to be applied, the first layer should be thin, it is recommended to spray: the solution is brought to liquid state(like liquid sour cream), drops are applied to the surface of the wall with a brush or brush. After they have dried, you can begin plastering;
  • 4) The main layer is applied different methods. A thin coating does not require the installation of a mesh; it is applied with a wide spatula or building rules. You should immediately make the surface level. If the layer is thick, it is advisable to stretch the mesh and secure it to the wall with dowels, even if the plaster manufacturer does not say so. Reinforcement is necessary for mortar layers from 50 mm.
  • 5) When using gypsum plaster and its high-quality application will not require subsequent puttying. When working with cement composition after 1-2 hours, if there are significant unevenness or teals, you can take a brush, moisten it in water and slightly blur the unevenness. Don’t be afraid to rub the wall - the cement has already set and only the surface will become wet if it is not leveled enough. Then puttying should be done.

This algorithm is valid in cases where repairs are carried out for the purpose of insulation in a finished building with an insulated facade. If the house is just being built, it is necessary to provide sufficient wall thickness or high-quality insulation from the outside, since the interior alone cannot protect the room from heat loss.

To give the building additional thermal insulation, warm plaster is used - a material based on cement and composite materials: expanded vermiculite, perlite sand, pumice powder, expanded polystyrene, etc. Depending on the type of such fillers, it can be used for both exterior and interior decoration.

Purpose

Although thermal insulation properties this material is higher than that of ordinary plaster, but it cannot replace the full insulation of a house with mineral wool or expanded polystyrene, but it will be a good addition.

  • facade insulation;
  • heat and soundproofing material for finishing interior and exterior walls;
  • insulation of balconies, verandas, door and window slopes, stairwells etc.;
  • sealing floor joints, cracks and cracks;
  • heat insulator for well masonry;
  • material for finishing work in premises;
  • insulation of water supply pipes;
  • thermal insulation of floors and ceilings.

How much more effectively does such a coating retain heat? Let's compare the main indicators - thermal conductivity coefficients: for a simple cement-sand plaster it is equal to 0.93 W/m °C. And for cement-expanded polystyrene (Knauf Grünband) it is already 0.35 W/m °C, which is almost three times lower! Gypsum plaster with filler will have even lower thermal conductivity, about 0.25 W/m °C.

Types of thermal insulation solutions

The main difference between warm plaster and regular plaster is the replacement of sand in the mixture with more voluminous heat-insulating components. Such mixtures may differ not only in composition, but also in application methods and technical and operational characteristics. We list the main types of such fillers:

The thermal insulation properties of this material will largely depend on the correctness of the work and compliance with the proportions when mixing. If all conditions are met, you can get not only insulated walls, but also additional sound insulation. In general, plastering with these mixtures does not differ from usual, so no special skills are required from the master.

Among various types insulation materials in construction are beginning to increasingly use the so-called "warm" plaster.

It differs from ordinary plaster lower thermal conductivity coefficient, which contributes to better heat retention in the room and, accordingly, saves heating costs.

The point is the filler, which has very high porosity. Air bubbles delay the transfer of heat to the surrounding space.

As a filler can be used for warm plaster various materials: sawdust, polystyrene foam balls, perlite or vermiculite granules, foam glass.

They all have lower thermal conductivity than the sand used in conventional plaster.

Compared to traditional insulation materials, it has a number of advantages:

  • Its application is quite simple, does not require special skills, and in private construction you can do all the work yourself. At the same time, you can also use a plastering machine.
  • Preliminary leveling of the surface is usually not necessary, and for better adhesion it is enough to wet the walls with water.
  • Reinforcing mesh will only be needed in particularly difficult places (for example, corners or where there are cracks). This not only simplifies the work, but also improves thermal insulation.
  • High adhesion ensures good adhesion to any surface, so you can insulate structures from almost any construction materials, including from concrete slabs or metal.
  • High ductility allows you to seal hard-to-reach areas without any problems.
  • Most types of warm plaster are not flammable and do not emit harmful substances, which increases the safety of structures.
  • Biological stability is manifested in the fact that fungus, insects or rodents are not able to live in such plaster (with the exception of types where sawdust or cellulose pulp is used as a filler).
  • High thermal insulation properties warm plaster allows you to use its thin layer as additional insulation.
  • Microporous structure makes the material breathable, which is especially important for residential premises, hospitals, schools, kindergartens.
  • Many wall materials lose their original lower thermal conductivity due to the absorption of water. And the porous structure of the plaster with a large number of capillaries helps remove moisture from the walls on which it is applied.
  • Modern warm plaster resistant to sudden changes temperatures, snow, ultraviolet rays, practically does not lose its appearance, does not crack.
  • It distributes absorbed solar heat evenly over the entire surface.
  • Often in the production of warm plaster waste is used(expanded clay chips, sawdust, etc.), which helps reduce environmental pollution.
  • And at the same time, it does not contain harmful substances. This the most environmentally friendly view among modern insulation materials.

Of course, warm plaster is not without cons, otherwise it would have long ago displaced other types of insulation from the construction market:

  • Main disadvantage- this is its high cost compared to traditional materials - glass wool, etc. Although this is primarily due to its novelty for domestic construction. And if we take into account the cost of related products for other types of insulation (for example, fittings), then the prices for them are closer.
  • Most types of warm plaster not suitable for final finishing external walls. Due to their porous structure, they quickly absorb moisture and become damp. Therefore, priming and topcoating with paint or plaster, or covering the walls with waterproof material are necessary. Polystyrene foam or foam glass plasters do not have this drawback.
  • The thermal conductivity of warm plaster is higher than competitors (0.065 W/m °K versus 0.033 - 0.043 for foam plastic and 0.041 - 0.05 for mineral wool). Due to this, a thicker layer of insulation will be required, which means the foundation must be stronger.
  • A thick layer takes longer to dry, which must be taken into account when working outdoors in changeable weather.
  • Plasters with organic fillers are heavier than others and absorb water more easily. Therefore, it is not entirely suitable for outdoor work. And in the humid environment of sawdust, conditions are created for fungus.
  • Polystyrene plasters are flammable, except for the most modern brands.

What's next?


Warm plaster
- Not perfect material for insulation without a single drawback.

However, she has a lot of advantages, which makes it attractive for both private and public construction.

The highest quality are new types, such as “Bear”, ThermoUm, which allow you to perform and finishing facades. They are waterproof and have an attractive white and an interesting surface texture; if desired, they can be painted. And because of their good ductility, you can also make decorative elements, for example, stucco.

If, as domestic production expands, prices for warm plaster decrease, then this type of insulation can become a leader on use, especially in the private sector.
