Is it worth waiting for the building to shrink for a couple of years? Perform cosmetic repairs during this time, which will then have to be redone with more expensive and desirable interior solutions? These questions arise for owners of apartments in new buildings or developers when building from scratch in private housing construction.
Decorative wall decoration in such buildings may become covered with a network of cracks or even come apart. Of course, you can wait to be safe. But why give a delay to a good repair when modern elastic plasters are offered on the building materials market. The set of constituent elements provides a reliable polymer coating without deformation during long-term use. The plaster composition is used for interior finishing work and is suitable for application to building facades.

These plasters contain polymer binders and additives. Which allows you to achieve the following effect:
It is plastic, and such material is easy and convenient to work with. Therefore, the expensive, but practical and technologically advanced material has found its specific niche in construction and well-deserved love among consumers.
Indoor use
Elastic plaster is suitable for interior wall decoration. It is used to perform thin-layer finishing work: applying a finishing leveling layer for painting or an equivalent replacement of decorative and textured coating. It allows you to form a variety of structural surfaces, which are distinguished by their strength and durability.
A mineral additive made from quartz chips will enhance the decorative effect of the plaster and create a monolithic surface that is particularly practical
You can watch the video for how to apply mosaic elastic plaster yourself:
On the bases of such plaster you can create bas-reliefs, moldings, and rosettes. You can paint on top of it.
Before painting the surface, use a paint that does not conflict with the base. So, if acrylic is present in the composition, then the paint should be chosen on the same base.
Use on building facades
On external walls, the elastic mixture adheres tightly to the base and provides reliable protection from all weather conditions. It can withstand large temperature changes and exposure to moisture.

Does not increase the load in light insulation systems. With good adhesion to all materials, it is the optimal choice for covering foam insulation and external protection of frame houses.
Such houses are not subject to ordinary plastering. Thus, mineral mixtures do not adhere to a wooden base and crack. Here, the solution is cladding with vinyl panels or elastic mortar. The modern formula provides a crack-resistant coating. When wooden panels play under the influence of temperatures, the plaster stretches and maintains its integrity.
An excellent appearance and decorative effect can be achieved by applying the mixture using different methods and tools. Using a trowel or roller will give a different effect and finish pattern.
The process of preparing and applying this solution does not require additional preparation or a high degree of qualification. These works can be successfully completed independently.
The elastic plaster mixture has increased strength and reliability and allows you to create an excellent appearance of walls both indoors and outdoors for many years.
Acrylit-415 is a composition intended for leveling surfaces made of cement, asbestos, concrete, wood, OSB, brick, chipboard and other materials. The key characteristic of this product is its elasticity, which prevents cracking of the surface after shrinkage, and, therefore, saves time and money on repeated repairs.
The high vapor permeability of elastic plaster for interior work or facade treatment ensures natural moisture and air exchange in the building.
The selection of colors for the composition is carried out using the RAL table.
Container: plastic Euro tanks and buckets with a volume of 5, 10 and 33 liters (plaster consumption 2 kg/m2).
The plaster is produced in several versions: KZ - coarse-grained, SZ - medium-grained, MZ - fine-grained.
Elastic plaster for facades Acrylit-415 does not affect the environment, because its unique formula does not contain toxic components. This is an acrylic composition that looks like ordinary plaster. Elasticity allows the material to form a uniform coating and not crack.

PURPOSE OF ELASTIC PLASTER
Facade elastic plaster on OSB Acrylit-415 is created for decorative finishing of external walls and facades, internal partitions of buildings. The product has high adhesion to various materials, so it can be applied to cement, concrete, wood, plaster, asbestos, brick surfaces, chipboard and OSB. Plaster forms a coating that “breathes” and does not collapse under the influence of moisture. The composition can decorate the surface and mask any defects. Elastic facade plaster is available in white, but can be colored in any shade. Colors are selected according to NCS and RAL catalogs.

Preparation . Clean the surface from dust and dirt, loose particles, and dry it. In order for the plaster to adhere better and adhere to the wall, it is recommended to treat it with water-dispersion impregnation Acrylit-06. The composition must be stirred well before application, making sure that no air gets into the mixture. If air bubbles still form, you should cover the bucket with elastic facade plaster with a lid and leave for half an hour.
To give the composition the necessary viscosity, you can add water to it. It is important to ensure that Acrylit-415 is not exposed to direct sunlight at the time of application. If work is carried out in sunny weather, the wall is protected with an awning. Do not apply the composition to a wet surface or in damp weather.
Application Features . The putty is applied to the surface from top to bottom using a sprayer or spatula. The wall should be processed from corner to corner in one step; it is impossible to leave the surface not completely plastered. The process of applying elastic plaster must be continuous, so it is necessary to ensure a sufficient number of specialists, tools, and working hours. The plastered surface dries in 1 day.
If elastic plaster for interior work or facade treatment is applied with a spatula, it is necessary to hold it at an angle so that the coating comes out even. After application, the surface should be immediately treated with a damp trowel. It is necessary to have time to level the surface before the composition dries and becomes covered with a film.
After finishing the work, the tool should be thoroughly rinsed with water so that the decorative elastic plaster is washed off without any residue.
Operational care
It is necessary to remove dirt from the plastered surface with a hard-bristled brush, which can be moistened in an aqueous solution of a cleaning agent. Metal brushes cannot be used; nylon brushes must be chosen.
Storage
Acrylit-415 can be stored at a temperature not lower than + 5 degrees for 12 months from the date of manufacture. Plaster can only be transported and stored in a hermetically sealed container at an ambient temperature of 5 to 30 degrees.
Precautionary measures
Elastic facade plasters with a water-dispersion composition do not ignite or explode, and therefore do not require special protection during application. When working with them, standard sanitary and hygienic rules must be observed.
Compound
Decorative elastic plaster contains acrylic dispersion, special additives and fillers, and water.
In recent years, elastic plaster for facades has become an increasingly popular type of finishing. And this is no coincidence.
Traditional types of such coatings are made using gypsum, lime, cement-sand and combined mortars. Such cladding, while having undeniable advantages, also has significant disadvantages. They arise from the inability of such a monolithic finish to stretch and shrink without destructive consequences.
But every building regularly experiences movements that are associated with shrinking walls, natural and man-made vibrations of the soil, and temperature changes. All this leads to deformation of the plaster and the formation of cracks in it.
They spoil the façade of the building, promote the penetration of moisture into it, thereby accelerating the destruction of the coating and the walls themselves.
Modern polymer-based plaster will help solve this problem.
Characteristics of plaster
The price of the material is not much higher than traditional analogues. At the same time, it has a lot of advantages.
Definition and composition of material
- Elastomeric plaster compositions are classified as finishing, that is,. When applied to surfaces, they create an all-weather protective membrane over them. This durable, reliable, non-fading and non-mouldy coating is intended for wall decoration.
- The material creates a decorative colored cladding. The instructions say that its service life can be more than 10 years in atmospheric conditions of a temperate climate. This is if you correctly follow the technology for applying plaster and its operation.
- In most cases, a material is produced with a binder of acrylic resins and cement. These polymers contribute to increased surface resistance to cracking. When the walls are deformed, the plaster stretches along the base, without breaking.
Note! Elastomeric plaster has a unique level of adhesion and does not come off the wall even under very heavy loads. The stretching of the material can reach up to 10 percent of its volume. Thanks to this quality, the coating can be used on gas and foam concrete, foam plastic and OSB boards.
- The material is available in a variety of colors.
- To increase strength and create decorative effects, fillers are used in the plaster - marble, granite chips, medium-fraction quartz sand, etc.
Purpose and properties
- Elastomeric plaster has good adhesion to almost all building materials: brick, concrete, natural and artificial stone, metal, plastic. Therefore, it is optimal for exterior decoration of houses with any walls.
- In addition, the acrylic coating is flexible, durable, resistant to cold, humidity, and does not burn. Based on this, it is ideal for buildings with a frame made of light metal structures.
In addition to facade varieties of material, elastic plaster for interior work is also produced.
- Flexible compositions are an excellent alternative to other types of decorative plaster - textured, Venetian, bark beetle, etc.
- They can be used without tinting, painted before application in any color, or already have it when sold.
- The elastic coating is suitable for subsequent creation of artistic painting on the wall.
- This type of cladding has great decorative potential, because... with its help you can create a variety of surface textures.
Note! If you need to color the composition, remember its important features. Since it is made on the basis of water-based acrylic polymers, it is best to paint it with acrylic paints and varnishes.
Laying the covering
Elastic plaster compositions can be applied either manually or mechanically. For independent work, the manual method is more suitable, because... For one-time use, it is not advisable to purchase expensive equipment.
Required materials and tools
For example, let's take a house with a facade area of 150 m2.
For finishing you will need:
- 300/500 kilograms of elastic plaster, which depends on its consumption, which can be 1.7/3 kg/m2;
- 3/4 pack of sealant;
- 20 liters of soil;
- if necessary - acrylic paint.
Tools for work:
- hard textured roller;
- large brush or spray gun for priming;
- for laying plaster.
The process of plastering walls
- In order to cladding the walls with high quality, you need to carefully prepare them with your own hands. Remove the old topcoat from the surfaces, and then the plaster. Clean the base from dirt and dust, then level it with cement-sand plaster.
- Next, the walls need to be primed. This will increase adhesion, i.e., the level of adhesion between the base and the decorative coating. If necessary, apply 2/3 layers of primer.
- Then you need to prepare a solution. Pour acrylic, cement and the filler you are using into a container, mix them, then pour in water. Stir the plaster using a drill with an attachment until you obtain a composition that has a uniform consistency.
- To apply the coating you will need a spatula and trowel. The layer of solution should be thin, but not less than 1.5/2 mm.
- To level out small unevenness on the . It is mounted on fresh solution. Next, the mesh is covered with a second layer of plaster. The wall must be aligned from the middle to its edges.
- Next, remove the protruding areas with a spatula and smooth out the holes.
- After this, patterns and drawings are created using the wet plaster. This is done using a textured roller.
Conclusion
Facade elastic plaster is a modern finishing material that significantly expands the possibilities for decorating walls. In this case, the cladding is reliable and durable, moisture-resistant, frost-resistant and non-flammable. The coating is quite easy to apply and you can do it yourself.
By watching the video in this article, you will receive additional information on the topic.
For the facade it performs several functions simultaneously. First of all, it helps to hide surface unevenness and cracks up to 2 mm, while protecting the application material from aggressive environmental influences. Nowadays the market offers a wide selection of different plasters, such as: facade plasters, coat plasters, carob plasters, acrylic plasters, cement and gypsum plasters and putties. The choice of plaster should be approached responsibly and slowly, and you should decide on the texture of the plaster, color, composition, and method of application. It is also necessary to take into account the degree of environmental impact and how often the surface will be cleaned. ElManto flexible plaster is an ideal option for finishing the facade of your home.
Any modern building materials can be susceptible to cracking. They appear during transportation, construction, and from exposure to the external environment. The most common type of cracks appears as a result of building subsidence due to subsidence of the foundation. As a rule, these are young houses made of foam blocks, aerated concrete, expanded clay concrete, and bricks up to 1-2 years old. Protecting the facade from cracks is the most important task of good plaster. The coating must protect the façade material from the effects of temperature changes, sunlight, wind and moisture. Flexible plaster is capable of performing the above protective and decorative functions of hiding cracks due to subsidence of the building under its own weight. Application of flexible coating allows you to avoid repeated plastering work.
The main advantages of using flexible polymer plaster EL MANTO are ease of application, elasticity and reliability. Plastering requires minimal skills. The flexible surface covers almost any unevenness, including joints products. The plaster can stretch up to 110% after application, hiding cracks after the inevitable subsidence of the building. It has pronounced protective functions from the effects of the external environment: precipitation, temperature changes, weathering. El Manto adheres well to brick, concrete, cement and even metal surfaces, as well as to insulation such as mineral wool or polystyrene foam. It can be used for finishing coating of already plastered surfaces.
Elmanto, knock-o-flex and Palladium plasters are resistant to frequent changes in weather and at the same time retain elasticity over a wide temperature range. For example, Elmanto plaster is guaranteed to withstand more than 150 frost resistance cycles after application. The plaster is waterproof, but it allows air to pass through freely. This feature of the plaster does not allow moisture to accumulate under the surface and thereby prevents the formation of mold and mildew.
The basis of flexible elastic plaster is granular particles made of marble chips - coronite, which look like microscopic polyhedra. This feature increases the area of contact of the plaster with various materials, while increasing the strength of the plaster layer and the adhesion strength of the plaster to the surface. High hiding power and adhesion are the hallmark of Elmanto plaster.
Flexible and inexpensive El Manto plaster, like good expensive imported American elastic plaster, can be used for both interior and exterior finishing work. The basis of the plaster is water-based acrylic + mineral fillers. The plaster is resistant to chemical influences, does not fade in the sun, and breathes. Interior work is possible due to the absence of odor after drying. The most famous American plasters are stuc-o-flex and Palladium.
Elmanto flexible plaster does not require special care. If El Manto suddenly appears to re-crack due to extreme shear or building settlement, unusual severe conditions, simply reapply El Manto to the cracks. To clean dirt or dust, you can use Karcher-type high-pressure washers under low pressure or just a hose.

Plaster is one of the most common materials for decorating external walls.
Choosing is sometimes not so easy: there is a huge amount of it on the construction market. Different manufacturers produce plaster using a specific technology. However, it is customary to divide façade mixtures into categories.
Elastic plaster has been developed especially for facades, which is intended for finishing walls outside. This coating can also be used indoors, but due to its properties, this plaster is most optimal for external decoration.
The main task of this coating is to protect the walls of the building and preserve the properties of the plaster when the walls shrink. The walls of any building are subject to slight shrinkage or deformation due to exposure to external phenomena, resulting in small cracks appearing on the walls. When covered with ordinary plaster, the finishing cracks along with the wall.
Elastic plaster forms a protective film, similar to rubber, which can stretch and does not deform. The basis of elastic plaster is acrylic resin. Thanks to the cement in its composition, a stable binding of all elements of the mixture is formed.
Polymer components serve to preserve the structure of the plaster when walls are deformed due to external influences.
In addition, the composition of elastic plaster includes additional elements that give decorativeness, slight relief and additional strength to the finishing base: fibers of natural or artificial origin, marble or natural granite chips, quartz sand.
Elastic plaster
Advantages
The elastic mixture is sold in a ready-made consistency, can be produced in the form of a dry water-soluble mixture, and is a finishing coating that has the advantages:
- easy to apply, forming a coating that does not have seams and is mechanically resistant;
- resistant to external influences;
- covers the formed cracks well, while maintaining strength and good adhesion to the wall;
- has good adhesive properties which allow the composition to be applied to any surface (concrete, OSB, osb, wood, chipboard);
- has vapor permeability, which helps create a normal microclimate in the room;
- dries quickly after application(this is especially true when applying the composition in several layers);
- does not emit toxic elements: environmentally friendly;
- retains decorative and performance qualities for a long time (more than 10 years);
- prevents the formation of mold and moss growth;
- suitable for application to both new buildings and old surfaces;
- resistant to temperature changes: can retain its properties from -50°C to +60°C;
- fire resistant;
- is UV resistant (retains color in the sun).
Elastic plaster is produced in different colors, however, if necessary, it can be painted in any other color.
When choosing a paint for painting elastic plaster, you should choose an acrylic-based composition.
This is necessary so that the polymers help maintain the stretching and contracting properties of the coating.
Flaws
This type of plaster mixture has no significant disadvantages: the material meets all requirements for preserving the facade. Elastic plaster is an order of magnitude more expensive than ordinary plaster, but its qualities are significantly superior to the usual mixture.
Varieties
Specifications
The elastic coating must meet the requirements according to GOST:
- linear stretch - +10% per m²;
- water resistance - 8 g/hour per m²;
- tensile strength - 7 bar;
- frost resistance - up to 150 cycles;
- fire resistance - class “A”;
- storage temperature - from +5°C;
- service life - more than 25 years (with preservation of properties);
- resistance to salt - up to 300 hours of continuous exposure.
In addition, the elastic coating must have positive adhesion characteristics in relation to types of surfaces, such as: OSB, foam block, concrete, brick, plasterboard, glass, rubber, metal, wood, SML, plywood, polyurethane foam, chipboard.
What is the difference between elastic plaster for facades and other types
The main advantage of rubber plaster is the preservation 
its properties during shrinkage or deformation of the wall, as well as when small cracks form on the bearing surface.
Conventional mixtures do not have elasticity, therefore, when the structure of the surface on which they are applied changes, cracks form on ordinary plaster.
Besides, the temperature range that ordinary plaster can withstand is less than that of an elastic structure, this is especially true for negative indicators.
In severe frost, there is a risk of cracking of cement-based plaster.
When a conventional composition is exposed to ultraviolet rays, some of the properties of the coating are lost. The limited color palette of cement mixtures is one of the indicators by which they are inferior to their elastic counterparts.
An essential indicator of an acrylic mixture is vapor permeability.
Areas of use
Elastic plaster can be used both outside and inside.
Due to its properties to withstand temperature and moisture, this type of coating can be used to protect the façade of a building from cracking.
Indoors, elastic plaster can be used as a painted design, stencil painting, wall covering as a decorative design.
Elastic coating performs well in places with difficult operating conditions, as well as in rooms with high humidity: bathrooms, halls, corridors, staircases.
Surface primer
Despite the fact that the elastic coating has excellent adhesive properties, it is necessary to carry out a number of works to prepare the coating for its application.
First you need to level the wall, remove protrusions from it; if there are pockets of mold, treat them with antiseptic agents, clean the wall of dust and, if there is any, of the old coating.
NOTE!
If the bases have a porous structure, then they should be treated with a primer twice.
Sometimes the surface requires triple application of primer.
The last step before working with elastic plaster is to inspect the surface and determine its verticality. Elastic plaster is applied in a thin layer and is not a mixture that significantly levels the walls. In case of large flaws, a reinforcing mesh should be applied to achieve a smooth surface.
Primer
Surface reinforcement
When it becomes necessary to reinforce a wall, after priming it is glued (preferably fiberglass) to the surface using an adhesive solution or secured with dowels. When applying the mesh, the joints must overlap.
CAREFULLY!
The mesh must not be allowed to sag: to do this, it must be well tensioned.
If sagging occurs, it will cause gaps to form between the putty and the wall, which can lead to the mixture peeling off.
When the mesh is tightly fixed, the beacons should be set and the first layer of leveling plaster should be applied.. Application should be made with sharp movements (throwing parts of the composition onto the mesh) for greater adhesion. After the first layer has dried, apply the second and wait until it dries completely.
When the wall is leveled, you should begin applying elastic plaster.
Reinforcement
Application of elastic plaster for facades
To calculate the required amount of elastic plaster mixture, it should be borne in mind that the standard material consumption ranges from 1.7 kg to 3 kg per m² of surface.
If the mixture is dry and is intended to be mixed with water, then immediately before applying it, the composition should be prepared according to the manufacturer’s recommendations indicated on the packaging of the dry material.
To do this, you will need a container for putty, cold water and a drill with a mixer attachment. After complete dissolution of the dry powder, the composition is ready for use.
The mixture must be applied starting from the center of the surface, moving to the edges so that each portion of plaster is applied from the wet part to the dry part.
The standard application layer should be no more than 5 mm. Manufacturers recommend a finishing layer of at least 1.3 mm, otherwise it will not meet the required characteristics. If necessary, the walls are covered with finishing twice.
Due to the fact that elastic plaster dries quickly, its application should be done with quick movements.
In this case, it is necessary to level and apply the mixture at the same time, then immediately clean it to make the treated surface smooth. Unevenness and minor defects should also be eliminated without waiting for drying, using a spatula.
At the final stage, it is possible to paint the surface, or apply a drawing or painting. Various designs are applied using a textured roller. This does not require complete drying of the elastic composition.
Applying the finish
Preparing the mixture
Thus, with a huge variety of facade finishing materials based on mixtures, an elastic coating is perhaps the best option: plaster is durable, resistant to external manifestations, has the property of stretching, while maintaining its appearance. In addition, this type of plaster can be painted, changing the design of the building at your discretion.
