Decorative lamb plaster has always been popular, back in the 20th century. It was used both for finishing the facades of buildings and for interior walls premises. This type plaster has a structure in the form of small pebbles the size of small grains. Allowed to be applied to various materials and bases: plasterboard, cement, clay, lime, plaster mixtures, polystyrene foam, mineral wool.

Lamb plaster

Production Features:

• The materials for making the mixture for this type of decorative plaster are: high-quality white cement, mineral fillers and other components from leading European ones.
• Acrylic composition may be applied to mineral wool, since acrylic resin is added to the composition.
• Composition of this decorative mixture is heterogeneous, so you can achieve almost any effect: wood, watercolor stains, sand, etc.
• The composition of the mixture is environmentally friendly and does not cause harm to health (quartz, marble, dolomite).

The beautiful Lamb plaster is shown in the selection of photos below, here are both the facades of houses and interior decoration apartments.

Advantages of this type of plaster:

• Excellent adhesion to the surface.
• Resistant to sunlight.
• Easy care. This type of plaster is resistant to moisture and temperature changes.
• Resistant to direct sunlight.
• Quite simple and understandable application technology.
• The material is elastic and easy to use.
• Good resistance to mechanical damage, shocks and scratches.
• This plaster perfectly allows steam to pass through and does not form condensation.
• The structure of the plaster holds its shape perfectly after drying.

Before you start processing surfaces or walls in your home, you need to purchase equipment: a bucket for the mixture, a set of spatulas, a plastic grater and masking tape.

When working with the material, take precautions: use gloves, avoid getting particles into your eyes and mucous membranes.

Applying plaster to the wall

Technology of applying decorative mixture

It is very important to use the mixture before it starts to dry out. Therefore, prepare thoroughly in advance.

• Plaster of this type is structured on the surface within the next 15-20 minutes. Therefore, you need to calculate the application area in advance. If you have big wall, it is better to work with an assistant: one applies the mixture, the other gives shape using a plastic grater.

  

• To achieve the desired effect, the plaster is applied smoothly and continuously. Also, the size of the granules in the mixture must match the thickness of the applied layer.

  

  Various application options

• Immediately after applying the Lamb plaster, immediately remove the excess. Use a putty knife to remove excess plaster. To prevent the solution from drying out during finishing, stir it periodically.

  

  Removing excess

• If you plan to paint the plaster, use two tones to create depth. First, apply a dark shade of paint and carefully process all the cracks. Then light movements without strong pressure - lighter.

  

• Finally, the walls can be coated with varnish or wax to make the surface shiny.

  

  Glitter effect

• The secret to the texture is applying the plaster using a roller that already has a relief on it. Too sharp lines, if desired, can always be smoothed out before the mixture dries.

  

• The effect of lamb wool is achieved by moving a special plastic grater during application. They should be smooth and circular to create chaotic grooves in the material.

  

• Before applying the mixture to the walls, try applying it to a test smooth surface and give the desired relief. This training will help you understand the technology faster.

  

  Test application of plaster

• Sometimes not all walls are covered with Lamb, but only protruding areas or architectural modeling. More interesting view You can also give it a coating by painting it with several colors, correctly placing accents. It is important here to ensure that everything looks harmonious and matches the style of the interior.

  

  Surface painting

The decorative mixture of this texture looks excellent on the surface and suits any interior and landscape, and the finishing process is not complicated and understandable. Therefore, observing all the rules and following the advice will help you get the desired result.

What is good about a decorative facade?

Plaster or wet facade is one of the most beautiful options facade of the house.

Valentin63 FORUMHOUSE Member

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

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

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

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

Types of decorative plaster

When choosing what to plaster the facade of a house with, you should take into account that, based on their composition, decorative plasters are divided into acrylic, mineral, silicate and silicone.

Main characteristics of decorative plaster mixtures

Each material has its own purpose: each can express itself the best way under certain conditions.

Oleg Lvovich Member of FORUMHOUSE

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

Let's look at each type in more detail.

Mineral

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

This type is valued for its ability to be used when plastering facades with any type of insulation and for its low cost. "Mineralka" is the most cheap look decorative plaster. But since she cannot perform the functions decorative finishing, this is a relative advantage.

Oleg Lvovich

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

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

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

nadegniy FORUMHOUSE Member

It is more difficult to plaster with mineral water (it sets immediately after mixing), there is more chance of losing it in the summer rain, it dries for at least 72 hours, and then you need to paint it on top 2-3 times.

Many participants on our portal, when deciding how to plaster the exterior of a house, quite often use this type. Even wooden facades are finished with mineral water.

Acrylic

Acrylic plaster contains acrylic resins, which explains the high elasticity of the material. Acrylic plaster is used for finishing the facades of new houses - with slight shrinkage it stretches and does not form cracks. Another outstanding feature is its minimal moisture absorption, which is why it is used in regions with high humidity.

The main disadvantage of acrylic is insufficient vapor permeability. This important characteristic: in a multilayer structure, each next layer in the direction from the inside to the outside (from heat to cold) should be more vapor permeable than the previous one. Thanks to this, the steam is removed outside the house, rather than falling into the liquid inside the façade structure.

People's sweat and breath, a boiling kettle, heated soup, etc... It is not known how much it will actually cost per family, but if some of this falls into condensation inside the wall, it is enough to shift the dew point to the inner surface of the wall, which will cause an increase in condensation. Eventually wet wall, fungus, mold. Thermal insulation deteriorates, temperatures drop, and energy costs rise. And renovations are on the horizon again.

When choosing decorative plaster, you should follow the recommendation of a specialist wet facades, member of FORUMHOUSE with the nickname nadegniy.

Nadegniy

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

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

Silicone

If acrylic plasters have disgusting vapor permeability and high elasticity, and mineral plasters, on the contrary, have extremely weak tensile strength with excellent vapor permeability, then silicone has the highest elasticity with excellent vapor permeability.

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

Agrachoff FORUMHOUSE Member

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

Like acrylic plaster, silicone is a ready-to-use material that does not require dilution with water; it can be tinted to the most different colors(the choice of colors is really great).

Fur coat

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 was hard and with crystals, the texture was true to size river sand. I don't really like bark beetles.

The simplest, 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, you need to walk over the applied solution with a broom to ensure uniformity. It can be done easier: apply the solution to the wall in the usual way and immediately go 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 outside of the house is the method of insulation.

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

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: what more embossed surface, the longer the plaster on the facade of the house will last, the less susceptible it is to various external factors.

The methods for applying decorative plaster under Fur Fur are varied; for example, one of the options for such finishing is Lamb plaster. Textured mixtures are similar in their composition and application technology.

Composition of the mixture Lamb

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

The mixture contains mineral granules (photo), they do not settle as, for example, in cement mortar sand, but remain until the end

using the mixture afloat. An interesting option the surface under the lamb is for painting.

Properties of structural lamb plaster

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

This type of mixture has good performance properties:

The applied mixture of Lamb, even on a very uneven surface, can transform its faded appearance. This finishing method can be used to decorate not only the walls of a living space, but also the façade of a building. With its voluminous structure and straightness, this finish turns any surface into a beautiful design element. Lamb looks like an interesting option in combination with the design flat surface ceiling. Plaster mixture can be applied to any walls: concrete, brick, plasterboard, cement-sand, and is recommended for interior and exterior finishing residential and non-residential premises.

Application technology

To decorate walls under Lamb, you will need a special paint-primer, which contains quartz sand, and decorative Lamb plaster. And also a spatula or grater in order to apply the mixture and give it relief and structure.

After the plaster is applied to the wall, we begin to level the surface of the mixture, then remove the excess (photo). To do this, you need to walk along the surface with a spatula at an angle until the plaster is collected on the spatula.

While the surface is damp, you can begin structuring.

When choosing construction mixture, primer coating and material for finishing It’s better to purchase from one manufacturer, one construction brand, so you can ensure compatibility and durability of any coating, even Lamb.

Among the wide range of materials and technologies that are used for decorative design facades, is in special demand decorative plaster“lamb”. Its peculiarity 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 that imitates a dense arrangement of small stones.

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

Scope of application of the “lamb”

The wide range of applications of “lamb” is due to the numerous consumer properties of the material and the possibility of applying it to walls different types. This type of plaster is used for both exterior and interior design surfaces. Its pebble structure allows you to harmoniously decorate internal surfaces schools, hospitals and public reception areas. Alternative option it is also available for application facade decor V residential buildings. The material is easy to use and maintain.

Ingredients of the lamb mixture

As a basis for cooking working mixture dolomite, marble and quartz are taken. These are natural ingredients that are safe for interior work. Additional components that are used in plaster to decorate external facades are environmentally friendly and safe. Also, the composition usually uses polymer materials that perform a water-repellent function, are not toxic substances, and must always be certified. The treated surface has vapor-permeable properties, due to which condensation does not form on the surface, but creates a comfortable microclimate. Ready mix easy to use, the existing mineral granules that are included in its composition do not settle, but are completely used. They adhere perfectly to the treated surface until the mixture has completely hardened. This specificity allows you to create decorative patterns or used as a base for painting.

Video on how to make lamb plaster yourself:

Plaster can be not only the basis for subsequent finishing, protecting the walls from dampness and mechanical damage. She is capable of being independent decoration facades and surfaces inside buildings, if it is decorative plaster that differs from ordinary plaster in its composition and structure.

These materials include decorative plaster "lamb" which gives the walls an interesting three-dimensional texture.

Material characteristics

When choosing a composition for plastering your home, you need to familiarize yourself with its composition, properties, scope, and also make sure that it is combined with the material from which the walls are built. Basic information about “lamb” facade plaster is given below.

Composition and properties

The basis of the material, its binder is cement. But instead of ordinary sand, granular minerals are added to it as a filler and structure-forming component - dolomite, quartz, marble, etc. This natural materials, ensuring the environmental friendliness of the finished coating.

Polymer additives are also necessarily introduced into the composition of mixtures for external use, ensuring their frost resistance and water-repellent properties so that the plaster can withstand aggressive influence atmospheric phenomena.

It is impossible to make such a mixture with your own hands: this requires special substances and precise dosing equipment. But the most important thing is that it is necessary to maintain a balance between the density of the plaster and the size of the filler granules, so that when the solution dries, it does not settle on the surface, but is distributed throughout the entire volume and remains in place until the applied layer has completely set, creating a textured pattern on the surface.

Application area

The natural composition allows the use of such plaster inside buildings when the design requires it or it is necessary to ensure high strength and vandal resistance of the coating. But more often it is used for facade finishing.

Provided that all surface preparation requirements are met, textured plaster“lamb” can be applied to almost any substrate:

• brick;
• cement-sand;
• concrete;
• plasterboard, etc.

And thanks to its vapor permeability, it is ideal material for finishing walls made of foam or aerated concrete, preventing the formation of condensation indoors and ensuring a normal microclimate in them.

When plastering foam concrete on both sides, instructions must be followed requiring the ratio of the thickness of the inner and outer layers to be 2:1. This is necessary in order to ensure uniformly increasing permeability of the walls.

The finished coating has White color, can be easily painted in any color. But without a layer of paint it looks quite interesting, so it can serve as an independent decoration.

How to apply “Lamb” plaster correctly

As is the case with any other “wet” finish, the surface is first prepared: tapped to remove crumbling areas, all protrusions are cut off (mortar sagging, protruding reinforcement, stones), and cleaned of dirt and traces of grease.

• Using a roller or brush, the walls are treated with a penetrating primer recommended for of this material. For example, if they are very smooth, primer with abrasive additives will help give them the roughness necessary for normal adhesion to the solution.

Advice. Even if the surface seems strong enough to you and suitable for finishing without preliminary preparation, do not neglect the primer. The price of the material and the time spent on its application are small, but at the same time the quality of the finished coating increases significantly.

• Prepared right on the job site plaster mortar. To do this, you will need a large container and a mixing attachment for an electric drill. Water is poured into the container and the dry mixture is poured in the quantities specified by the manufacturer on the plaster packaging. After the first stirring until the solution is homogeneous, the solution is allowed to stand for a while to form molecular bonds in it, then stirred again and immediately begin to work.
• Depending on the thickness of the applied layer on each square meter the facade may require 3-5 kg ​​of dry mixture.
• Using a spatula or trowel, lamb facade plaster is applied to the walls in the usual way - the video will tell you in more detail about the application technique. You need to work quickly so that there are no visible joints between the already laid areas that have begun to dry out and the new areas.

Advice. If you do not have enough experience, try to distribute the solution so that the joints fall on inconspicuous areas: behind drainpipes, along openings and corners.

• The applied solution is leveled with a grater, a special roller or simply a spatula, under the pressure of which the solid mineral granules move randomly in the layer of wet mixture, leaving marks on the surface.
• It is difficult to cope with such work alone, since it is also necessary to periodically stir the plaster in a bucket, preventing it from delamination and rapid hardening. Therefore, it is usually performed with four hands - one person distributes the mixture over the surface, the second then rubs it.

As a result, the surface acquires a characteristic relief texture, reminiscent of the skin of a young lamb - where this name comes from. As mentioned above, it is advisable not to interrupt work until the entire plane of the wall is completely finished, so that traces of grips applied with a long gap in time are not visible on it.

Until the solution dries completely and gains strength, it is important to protect the surface from aggressive natural influences such as precipitation, wind, and direct sunlight. And also ensure normal temperature regime drying.

To do this, it is advisable to carry out work at an air temperature in the range from +5 to +25 degrees, and after completion, if necessary, install protective screen from film or construction mesh.

Conclusion

Watch the video about lamb plaster in this article again to consolidate the information received. Decide whether you can plaster the house yourself in this way and whether you are satisfied with the result.

But before you start, still practice on a back wall or concrete fence. If in reality everything turns out to be more complicated than you thought, you can always turn to specialists for help.
