Lamb plaster - the technology of correct application. Facade plaster lamb Lamb on the wall

Making wall decoration less primitive is very simple. A decorative mixture of the “lamb” type will favorably beat the surface, make it voluminous, and hide irregularities. Textured coating creates a rough layer due to the graininess of the mixture itself. Used for interior and exterior decoration.

Textured lamb plaster: features

"Lamb" is characterized by good impact resistance, high frost resistance, resistance to climatic influences, ease of application. The material is considered environmentally friendly: it contains quartz, marble, dolomite. Outdoor blends contain special water-repellent polymer-based components. An optimal microclimate is created in the room, condensation is prevented. The finished mixture is balanced in such a way that the plaster mortar with minerals forms a single mass during mixing and application. Sand in the usual cement-sand mortar can settle in the tank. The minerals in the composition of the "lamb" retain their position until setting and hardening. Dry matter consumption per 1 sq.m - 2-5 kg.

Application of decorative plaster "lamb"

Before applying plaster, clean the work area from loose layers, oily stains, paints. Primer pre-treatment is recommended. The range of use of the internal and lamb is quite wide: it is applied to a brick, concrete, plasterboard, cement-sand base.

The principle of mixing the finished mixture must fully comply with the instructions indicated on the package. A pasty consistency is obtained by using the attachment of an electric drill or a construction mixer. After stirring, let the paste stand for 5 minutes, then repeat the mechanical stirring. The solution is applied to the surface with a trowel, a stainless steel trowel, leveled with a grater, spatula, rollers. Mineral granules leave grooves that create a decorative coating.

When mixing the solution, calculate its amount in such a way that the area covered at a time "reaches" openings or areas with a different finish. This way you will avoid visible seams.

The methods of applying decorative plaster under a fur coat are varied, for example, one of the options for such a finish is lamb plaster. Textured mixtures are similar in their composition and application technology.

The composition of the mixture Lamb

Even if there are different manufacturers, the composition of the lamb mixture will always remain environmentally friendly and safe. Even water-repellent outdoor polymer materials always meet the certification. The basis of such a mixture is only natural ingredients: dolomite, marble, quartz. Therefore, this finish is safe for the interior. The finished coating on the facade of the house from the Lamb mixture has vapor permeability, so the house will always have a comfortable atmosphere, because condensation will not form.

The composition of the mixture includes granules of minerals (photo), they do not settle as, for example, sand in a cement mortar, but remain until the end

use of the mixture afloat. An interesting option for the surface under the lamb is for coloring.

Properties of structural plaster lamb

Today, mixtures for lamb finishing are available in various shades, so you don’t have to color the mixture yourself with color, and the palette of the finished mixture is simply amazing.

This type of mixture has good performance properties:

The applied Lamb mixture, even on a very uneven surface, is able to transform its faded appearance. In this way of finishing, you can decorate not only the walls of the living space, but also the facade of the building. With its three-dimensional structure and straightness, such a finish will turn any surface into a beautiful design element. An interesting option looks Lamb in combination with the design of a flat ceiling surface. The plaster mixture can be applied to any walls: concrete, brick, plasterboard, cement-sand, and is recommended for interior and exterior decoration of residential and non-residential premises.

Application technology

To finish the walls under the Lamb, you will need a special primer paint, which contains quartz sand, and decorative plaster Lamb. As well as a spatula or grater in order to apply the mixture and give it relief and structuring.

After the plaster is applied to the wall, we proceed to level the surface of the mixture, then remove the excess (photo). To do this, go over the surface with a spatula at an angle until the plaster collects on the spatula.

While the surface is damp, you can start structuring.

When choosing a building mix, primer coating and finishing material, it is better to purchase from one manufacturer, one building brand each, so you can ensure the compatibility and durability of any coating, even Lamb.

In Europe, they have long learned to take care of improving the environmental situation, and this has led to the adoption of strict standards for the thermal insulation of buildings.

The facade is the face of the house, which is constantly exposed to wind, sun, snow, rain, dust. must resist all the vagaries of the weather.

Four categories of facade plasters

• Based on cement -.

Characterized by fire safety, good vapor permeability and thermal insulation. But it has low chemical and dirt resistance, is not resistant to vibrations, therefore it is not used for buildings along roads.

• Based on acrylic resins - acrylic facade plasters.

For use on all mineral substrates. But they are inferior to mineral plasters in terms of vapor permeability.

• Based on potash glass - silicate plasters.

Can be used on any silicate bases. Possesses good vapor permeability, high biostability. Disadvantages - small selection of colors and high cost.

• Based on silicone resins - silicone facade plasters.

High vapor permeability, excellent water and dirt repellency. The price for this type of coverage is the highest.

Nowadays, there is a wide range of products for facade decoration, a variety of technologies and methods for applying facade decor.

But it deserves the best reviews from consumers. Finishing of this kind is used almost everywhere. Both on the facades of public institutions and on residential buildings. Its pebble texture allows you to decorate any facade, and the unequal and at the same time unique grain size gives originality to the surface.

Decorative plaster "Lamb» is used not only for finishing exterior walls, it is also great for interior surfaces.

The composition of the plaster "Lamb"

The composition of the plaster contains the safest and most environmentally friendly mineral components. Based on natural ingredients: marble, quartz, dolomite. The covering possesses vapor permeability, and it provides a comfortable microclimate of the room and prevents formation of condensate.

A well-chosen granulometric composition of the aggregate, balanced with the density of the plaster mortar, allows the mineral particles to form a single mass.

Properties of decorative plaster "Lamb"

• high level of frost and water resistance;
• excellent adhesion (adhesion of the material to the base);
• resistance to direct sunlight;
• impact resistance and elasticity;
• ease of maintenance.

This type of texture does not retain dust, dirt, has a more uniform structure. Due to the large number of grains of one fraction, the effect is achieved. After rubbing with a trowel, the material acquires the texture of small stones that are tightly packed.

Plastering technology

Important! Before starting work on applying plaster, be sure to follow the safety rules. Avoid getting plaster on any area of ​​the skin, especially the eyes. Work only with gloves. The temperature during application should be 5-25 C. Tools: stainless steel grater, spatula

Before applying the plaster, the surface is prepared. The surface must be clean, even and smooth, in no case should there be any residue of the previous coating. You also need to get rid of greasy spots, cracks, potholes. The base must be solid and dry.

After preparing the surface, it is primed with a special compound. After the primed surface dries, you can apply the lamb facade plaster. To do this, mix in the proportion indicated on the package, the finished mixture with water. You should get a creamy mixture.

The solution must be thoroughly mixed with a special nozzle with a construction mixer or an electric drill and left for 5 minutes. The solution must be used within 1.5 hours.

The layer must correspond to the thickness of the grains. Drying time of lamb plaster is from 12 to 48 hours.

What is good decorative facade

A plastered or wet facade is one of the most beautiful options for a house facade.

If we consider a building from the point of view of architecture, what is a stucco facade, then this is, secondly, insulation, and firstly, a beautiful surface.Plastering the facade gives a beauty that no other facade can give, not even marble.

The popularity of the wet facade is also explained by its relatively humane cost (it is more expensive than vinyl siding, but it is on par with fiber cement and brick trim).

The plastered facade is mounted on any walls, it is non-flammable and perfectly insulates light and weak walls, allowing you to save on gas and electricity.

The system consists of insulation, glue, facade dowels, a base layer of plaster, a reinforcing mesh and a finishing layer of decorative plaster. Every element is important in this pie, but the wrong choice of decorative plaster can simply ruin the whole thing, you have to “rip off and redo it”.

Types of decorative plaster

When choosing how to plaster the facade of a house, it should be borne in mind that, according to the composition, decorative plasters are divided into acrylic, mineral, silicate and silicone.

The main characteristics of decorative plaster mixtures

Each material has its own purpose: each can perform best in certain conditions.

OlegLvovich Member of FORUMHOUSE

Mineral water is an economical option, suitable for both PPP and mineral stoves. Acrylic is for PPS only. Silicone - for both systems, but the demand for it is low, higher for silicate-silicone. Silicate-silicone is suitable for both systems. And the textures of all plasters are visually indistinguishable.

Let's consider each type in more detail.

Mineral

There are no expensive components in mineral plaster; it is made from white cement, lime hydrant, sand or marble chips with additives. Such a coating is sold in bags in the form of a dry mixture, diluted with water before use.

This type is valued for the ability to use when plastering facades with any type of insulation and for a low cost. "Mineralka" - the cheapest type of decorative plaster. But, since it cannot serve as a decorative finish, this is a relative advantage.

Oleg Lvovich

Mineral plaster requires painting with high-quality hydrophobic paint, which ultimately equalizes the price of mineral water with acrylic.

Mineral water insulates the facade well, has high vapor permeability, that is, it "breathes", and it is quite resistant to fungi and mold.

But the gurus of wet facades of our portal consider this material obsolete.

nadegniy Member of FORUMHOUSE

It is more difficult to plaster with mineral water (it seizes immediately after kneading), there are more opportunities to lose it in the summer rain, it dries for at least 72 hours, and then paint it on top 2-3 times.

Many participants of our portal, when deciding how to plaster the facade of a house from the outside, quite often use this particular type. Even wooden facades are trimmed with mineral water.

Acrylic

The composition of acrylic plaster includes acrylic resins, which explains the high elasticity of the material. Acrylic plaster is used to finish the facades of new houses - with slight shrinkage, it stretches and does not form cracks. Another outstanding feature is its minimal moisture absorption, so it is used in regions with high humidity.

The main disadvantage of acrylic is insufficient vapor permeability. This is an important characteristic: in a multilayer construction, each subsequent layer in the direction from the inside to the outside (from warm to cold) must be more vapor permeable than the previous one. Thanks to this, the steam is discharged outside the house, and does not fall into the liquid inside the facade structure.

The sweat and breath of people, a boiling kettle, a heated soup, etc... It is not known how much actually per family, but if some of this falls into condensate inside the wall, it is enough to shift the dew point to the inner surface of the wall, which will cause an increase in condensate. As a result, a wet wall, fungus, mold. Thermal insulation is deteriorating, the temperature is dropping, energy costs are rising. And renovations are on the horizon.

When choosing decorative plaster, you should be guided by the recommendation of a wet facade specialist, FORUMHOUSE participant with the nickname nadegniy.

With a polystyrene foam system - any, with a mineral wool system - mineral, silicate, silicone, silicate-silicone.

Thus, it is not recommended to use acrylic plasters in systems with mineral wool insulation. When in doubt, read the fascinating discussion on FORUMHOUSE about the meaning of .

Silicone

If acrylic plasters have disgusting vapor permeability and high elasticity, while mineral plasters, on the contrary, are extremely weak in rupture with excellent vapor permeability, then silicone plasters have the highest elasticity with excellent vapor permeability.

Silicone plaster is made from silicone resins, fabric fibers and special additives for strength, durability and climatic endurance. It has all the possible advantages, except for one - the cost, which fits within the reasonable.

Agrachoff Member of FORUMHOUSE

But these silicon-based materials are more suitable for facade use than others.

Like acrylic plaster, silicone is a ready-to-use material that does not need to be diluted with water, it can be tinted in a variety of colors (the choice of colors is really great).

Fur coat

A fur coat is another popular texture, although some think that its time has passed and consider this type of facade decoration outdated.

LoraU Member of FORUMHOUSE

I would like to get the effect of a fur coat, black with quartz chips. In the 70s, schools were decorated with such a fur coat, it is tough and with crystals, the texture is the size of river sand. And I don't really like bark beetles.

The easiest, but also the longest way to plaster with a fur coat is spraying with a broom. To do this, the plasterer dips a broom into the solution and hits it on a stick, which is held at a distance of 20-30 cm from the wall. At the next stage, for uniformity, you need to walk through the applied solution with a broom. You can make it easier: apply the solution to the wall in the usual way and immediately walk over it with a roller. There are also various mechanisms for applying plaster to the facade.

These three types of textures are the most popular when finishing facades; they are produced by many manufacturers of both polymer and mineral plasters.

How to choose decorative plaster

One of the main factors that should influence the decision of how to plaster the house from the outside is the method of insulation.

Mineral plaster is suitable for applying both to foam plastic and mineral wool, silicate and silicone plaster to mineral wool, in the case of foam plastic, this will be a waste of money. Acrylic is applied only to the foam.

The most durable and resistant to damage and cracking is acrylic, followed by silicone, silicate, and mineral in descending order of resistance.

The service life depends on the texture: the more relief the surface, the longer the plaster on the facade of the house will last, the less susceptible to various external factors.

Among the wide range of materials and technologies that are used for the decorative design of facades, decorative lamb plaster is in special demand. Its feature is the ability to decorate the decor in an original way thanks to the selection of a unique grain size. The finished surface in this case is represented by a homogeneous structure, which imitates a dense stacking of small stones.

By the way, decorative plaster can be made from ordinary putty. You can find out how to do this.

Scope of "lamb"

A wide range of applications of the “lamb” is due to the numerous consumer properties of the material and the possibility of applying it to walls of various types. This type of plaster is used for both external and internal surface decoration. Its pebble structure makes it possible to harmoniously decorate the interior surfaces of schools, hospitals and public reception areas. It is also an alternative option for applying facade decor in residential buildings. The material is easy to use and maintain.

The components of the lamb mixture

Dolomite, marble and quartz are taken as the basis for the preparation of the working mixture. These are natural ingredients that are safe for indoor use. Additional components that are used in plaster for the design of external facades are environmentally friendly and safe. Also, polymeric materials are usually used in the composition, which perform a water-repellent function, and are not toxic substances, and must always be certified. The treated surface has vapor-permeable properties, thanks to which condensation does not form on the surface, but a comfortable microclimate is created. The finished mixture is easy to use, the existing granules of minerals that are part of it do not settle, but are completely used. They ideally adhere to the treated surface until the final hardening of the mixture. This specificity allows you to create decorative patterns or be used as a base for painting.
