Sanitizing plaster
The need to protect the premises from increased exposure to moisture is the basis for the use of sanitizing or «drying» plaster. The material helps to remove excess moisture from the treated surface and prevents the formation of damp spots.
Renovation plaster has a porous structure and has a large evaporation area, which is 10 times higher than the nominal value of usually plaster. The plaster layer is permeable to steam, because has a large number of pores and low absorption capacity. By the way, now workers and specialists in apartment renovation are very much appreciated by their services many people use every day..
Moisture penetrates through the plaster only in the form of steam, while the water is removed much faster than it can come from the base. Evaporation occurs inside the plaster layer, the treated surface remains dry. Sanitizing plaster is not destroyed by salts coming from outside. Moisture intake is reduced when special additives are added to the composition.
The layer of drying plaster should not exceed 2 cm, while the composition can be applied at one time or in several passes. The joints are reinforced with fiberglass mesh. The disadvantage of sanitizing plaster is its poor resistance to frost and drying out. For external protection, a «wet facade» wall treatment system is used.
