In the building materials market, gypsum plaster is a special place. It allows you to bring even the most uneven surface to the ideal state in as short a time as possible. By the way, gypsum plaster due to its porous structure provides a high level of agression, that is, "coupling" of materials. So if you cover it with the walls in the bathroom, you can not worry about how the tile will fall on plaster plaster - it will stick together if not tightly, then certainly very tight.
This universal material has another indispensable quality - it is rather hygroscopic, that is, it can absorb excess moisture. Therefore, for rooms in which high humidity is possible, for him - the very place.
Universal gypsum plaster
There are various brands on the market, among which Knauf gypsum plaster Rotband is very popular. It successfully combines high German quality and the ability to adapt to various external conditions. As already mentioned, it does not feel high humidity, as well as very uneven walls, ceilings and other surfaces. It equally well falls on concrete, coarse cement plaster , brick, even if a very thick layer has to be applied to remove unevenness. It can be covered with expanded polystyrene plates, which usually warm the walls, both outside and inside the room.
Naturally, many are interested in what are the advantages of this universal gypsum plaster. From the usual cement-sand mixture, which "in the old manner" is still used by some masters, it has such qualities:
- due to the content of polymer additives in it, it promotes a much stronger bonding (anodesy) of materials among themselves;
- The gypsum component gives the mixture a pleasant white color , which, with the imbedding of certain mineral particles, may acquire a pinkish or grayish tinge;
- The surface, covered with plaster knauf, becomes so smooth and smooth that it does not require additional coating - it can be painted immediately;
- the appearance of cracks (the so-called "grid") on it is excluded, even with high humidity and a sufficiently thick layer of application (on walls - up to 5 cm, on the ceiling - up to 1.5 cm);
- very economical and easy to use.
In order to activate dry gypsum plaster, simply dilute it with water and mix thoroughly with a construction mixer. By the way, in addition to universal plaster on gypsum-based knauf, they offer also mixtures for machine application, starting, as well as for the most rapid leveling of surfaces (goldband). Despite the differences in the composition, they all combine good quality and quite reasonable cost.
Gypsum plaster Thermal
Another indisputable leader among plaster mixtures on the basis of gypsum - Teplon from the Russian manufacturer. Among its many advantages, it is necessary to note the main thing - its ability to keep heat.
