Description and scope of application
Plaster lamb has been popular since the Soviet Union. It was then applied as a coating "under a fur coat."It has a pebble texture with different grain sizes. Used for decorative finishing of facades and treatment of internal walls of premises. It is applied to almost all mineral bases( gypsum, cement-lime, clay, lime plasters).
It is often said that bark beetle and lamb are similar, so what is their difference? The fact is that these and other mixtures contain mineral aggregates and have a pebble structure. However, the bark beetle makes it possible to achieve a furrowed texture, and the lamb is rough and evenly grainy. Both have excellent consumer characteristics, but create different decorative patterns on the surface.
A mixture of white cement of the highest quality, functional components from the leading manufacturers of Europe, mineral aggregates is produced. A dispersion of acrylic resin is also added to the acrylic formulations. It is applied not only to concrete, gypsum plasterboard and gypsum substrates, but also to mineral wool plates. If the room is in a zone with a high level of humidity, where fungus and mold often spread, then a bactericidal compound( protective layer) is applied over it.
Properties of
plaster shavings As already mentioned, the lava plaster has excellent performance characteristics. It is available in all possible colors, so you can choose the most suitable in accordance with the general color palette. So, from the basic properties are allocated:
- Provides excellent adhesion( adhesion of the material to the substrate).
- Has a high level of water and frost resistance( about 75 cycles).
- Has elasticity and impact resistance. The process does not form cracks.
- Easy to operate and use.
- For a long time retains an excellent appearance and does not burn out in the sun.
Application technology
Before applying any plaster, it is necessary to prepare the substrate properly. Do it in accordance with SNiP 3.04.01-87.In fact, the surface under the finish should be strong, clean, smooth, smooth. It should not have past coverage in the form of paint, wallpaper, plaster( you need to think about how to remove old plaster).
Oil and grease stains are also eliminated by special means. Any irregularities, potholes or cracks are leveled with plaster. Dilute the mixture according to the recipe indicated on the package. Further, the base is primed with a composition suitable for a particular substrate. In this case, all work should be carried out at a temperature of +5 to +30 ° C( better +20 ° C) and humidity of about 75%.
Further textured stucco plaster is applied. She falls asleep in a container, is bred in water and stirred to a creamy state. Leave the solution for 5 minutes and stir again. Use it is important for 1.5 hours, because it is during this time that it retains its properties. In doing so, it is important to stir the compound periodically.
Apply the material with a special stainless steel float. The thickness of the entire layer is made equal to the thickness of the grains. The result is a surface with a rough texture, thanks to the grains. The drying time of the layer depends directly on the air temperature, as well as on the absorption capacity of the substrate.
The most detailed way to see the process of applying and using the material can be in a special video, the plaster of the lamb in which is shown in the process of work, and is applied by the masters-finishers. This will greatly help you during the finish.
