Sanitizing or restoration plaster is able to "pick up" moisture from the walls and take it out very quickly, as it has a porous structure. And thanks to hydrophobic impregnations, it prevents the movement of water and in the opposite direction. Such a surface is not an insulating or sealing system, it does not desalinate and does not dehydrate wall materials.
Such a coating is designed to restore buildings that have been damaged by moisture. Due to its protective properties, detachment of materials during operation does not occur, so it is very often used as a sanitizing plaster for the bathroom.
Features of sanitizing plaster
To combat moisture, only 2 cm of coating is sufficient. Preparation of the walls under the tile will take a couple of weeks, as this material must dry and cure.
Its merits are obvious:
- ecological cleanliness;
- protection from moisture and salts;
- on the walls are not formed tall and moldy;
- vapor permeability;
- sulfate resistance;
- does not crack during operation.
In addition, the sanitizing plaster is also used for wooden walls. She will protect them from dampness and fungus . It is not recommended to use it when plastering the basement of buildings, as well as plasterboard walls.
Since the composition of sanitating plaster includes building lime, cement, perlites and additives, then it should be applied to the walls in two layers. The principle of action is that excess moisture and salt is absorbed into a more porous layer and remains inside, thereby preventing its accumulation at the boundary. Due to this effect, the plaster does not exfoliate and serve for a long time.
Sanitizing plaster is an ideal choice for premises in which water is present, as it effectively fights with high humidity and harmful microorganisms.
