Elastic facade plaster El-Manto. What is good about elastic facade plaster Elastic plaster for external use

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. Various manufacturers Plaster is made using a certain 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, giving 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

Significant disadvantages of this type plaster mixture no: the material meets all requirements for preserving the façade. 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 this, 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. Limitation color palette cement mixtures is one of the indicators by which they lose to their elastic counterparts.

An essential indicator of an acrylic mixture is vapor permeability.

Applications

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.

PLEASE 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 level, 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 for mixing with water, then immediately before its application 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.

On 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: the plaster is durable, resistant to external manifestations, has the property of stretching, while maintaining appearance. In addition, this type of plaster can be painted, changing the design of the building at your discretion.

Master class on applying elastic finishing to the facade of a building:

IN recent years Elastic plaster for facades is becoming 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 contract 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

1. 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.
2. 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.
3. 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.

Pay attention! 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.

1. The material is produced in a variety color solutions.
2. To increase strength and create decorative effects, fillers are used in the plaster - marble, granite chips, medium-fraction quartz sand, etc.

Purpose and properties

1. Elastomeric plaster has good adhesion to almost all building materials: brick, concrete, natural and artificial stone, metal, plastic. Therefore it is optimal for exterior finishing houses with any walls.
2. 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.

1. Flexible compositions are an excellent alternative to other types of decorative plaster - textured, Venetian, bark beetle, etc.
2. They can be used without tinting, painted before application in any color, or already have it when sold.
3. The elastic coating is suitable for subsequent creation of artistic painting on the wall.
4. This type of cladding has great decorative potential, because... with its help you can create a variety of surface textures.

Pay attention! If you need to color the composition, remember it important feature. Since it is produced 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

1. 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.

1. Next, the walls need to be primed. This will increase adhesion, i.e., the level of adhesion of the base and decorative covering. If necessary, apply 2/3 layers of primer.

1. 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.

1. 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.
2. To level out small unevenness on the . It is mounted on fresh mortar. Next, the mesh is covered with a second layer of plaster. The wall must be aligned from the middle to its edges.
3. Next, remove the protruding areas with a spatula and smooth out the holes.

1. After this, patterns and drawings are created using the wet plaster. This is done using a textured roller.

Conclusion

Facade elastic plaster is modern finishing material, which significantly expands the possibilities of wall decoration. 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.

Olga, is that you? Hello! =)
As you understand, I received your parcel, thank you.
I like your material - now I’m testing it using various methods at hand. I have a few questions for you:
1. Does your company have a technical department or a production department? Please give me the phone number of a person (or invite him here for interrogation with passion =))) who would answer questions about the composition of the filler, vapor permeability, and so on.
2. Question for you, according to the above links under different brands, as far as I understand, the same product is hidden:

(TU TU2313-001-70998431-2005)
this is actually you: http://www.stena18.ru/product/Dekorativno-otdeloch/Spec/Elastichnaya_shtukat

- Elastic plaster Acrylit VD-AK-215 El
http://www.oliva.ru/catalog.php?binn_rubrik_pl_catelems4=283

The descriptions and markings are slightly different, but it seems to me that they are all the same. At least you and Acrylit for sure =))
So who is the manufacturer? Where did this technology come from? One of the links says about acrylic dispersion from Germany, is that correct?
3. Is stucoflex a prototype of your plaster? At least they have the same essence?
4. A little worried next question: After freezing the sample, the coating becomes brittle (which is probably natural). But with constant transitions from + to -, the linear dimensions of the pox will change, and the plaster may burst (if it is at a temperature below zero). In general, I am interested in the dependence of elasticity on temperature. Flexible tiles, for example, have such an indicator - flexibility on the beam - how the tile bends at -5 and -10 degrees.
5. It is indicated that it is necessary to protect from precipitation in the first 72 hours. You know, it’s not an easy task to fence a canopy over each facade. How critical is this? Will the coating wash off? It is also water soluble.
6. At the z-facade it is written: Facade waterproofing coating;

Can be applied to almost any type of surface;

Has a high coefficient of vapor permeability;
How to find out what exactly this coefficient is.

I like your material, I could even become a distributor in our region, but as long as there is no practice, I will not take responsibility.
Show practice (except faceless photos from Samara and Ulyanovsk) that the coating tolerates frost and changes in humidity, that moisture does not accumulate in the sippanel or in the frame without a ventilation gap.
If there are or are possible problems in the case without a ventilated facade, tell me. You will save many people nerves and money, and we will use your material only in ventilated facades.

Surface preparation

The surface should be cleaned of dirt and dust. The prepared surface must be dry, clean, and not crumbling. In order to strengthen the surface and improve adhesion, it is recommended to use water-dispersion primer Akrylit-06. Before use, thoroughly stir the material without forming air bubbles. Be careful not to allow air to enter during stirring. If air gets in, cover the bucket and let it sit for 30 minutes before use. It is allowed to add a small amount of water to achieve the required viscosity. When working with finishing material Acrylit-415 Elastic, avoid contact with direct sun rays. If you have to work in the sun, you need to protect the wall with an awning. Do not apply in damp weather or on a damp wall. It is necessary to monitor the thickness of the applied layer.

Application method

Apply with a spatula or spray. It is necessary to start application from top to bottom; you cannot leave the wall you have started unfinished, i.e. apply from corner to corner. The application process must be continuous, with a sufficient number of specialists provided. The duration of the drying process is 24 hours after completion of work.

When applying with a spatula, the tool must be held at an angle, this will ensure an even coating. Then quickly work the surface with a float in a circular motion. The edge should be damp. It is necessary to process the section that has not begun to dry out and form a film. Upon completion of work, rinse the tool with water.
