Any moisture on the walls inevitably leads to the formation of the most dangerous enemy of man - black mold. Even small changes in temperature can adversely affect, for example, corner rooms, and exterior walls quickly become a problem that is difficult to solve. It is, in principle, possible to get rid of mold with special means, but here's how to dry the walls. The key is to make sure the moisture source is isolated. That is, a pipe break or a roof leak has been eliminated, and the reasons for the formation of condensation have been clarified and resolved. Now the time comes for sanitizing plaster, and today we will talk about it.

What is sanitizing plaster
To begin with, sanitizing plaster is a special type of waterproofing that not only evens out the surface, but also draws out water.
Where you should not use such plaster: it is not suitable for waterproofing the foundation and supports from sources of moisture supplied under pressure.
How much does sanitizing plaster cost?
If we talk about the cost of sanitizing plaster, then it is higher than usual. For example, a 25 kg CERESIT bag costs about 2,000 rubles. And plus the application of this plaster has a lot of nuances, so in the absence of experience it is better to entrust this occupation to specialists.
Why is it worth it to fork out for sanitizing plaster
The prices for this type of plaster and the costs of application are thought-provoking, but its advantages pay off all the costs.
How does the material work? This new formulation results in a multi-pore structure that acts like living skin. Through them, moisture is removed from the wall, and does not remain inside, as with ordinary plaster.
Thanks to this structure, efflorescence does not appear on the surface. After drying, the mixture itself does not form cracks, it can be used for external and internal work.
The composition is absolutely environmentally friendly, that is, it does not emit any substances toxic to humans, and most importantly, it is at times increases the "lifespan" of structures, protecting them from fungus and creating a good, healthy microclimate in the room.
About the technology of applying sanitizing plaster
The fact is that the sanitizing plaster mixture by itself does not work, it is imperative to observe the special technology of its application, otherwise it will be wasted money.
First of all, the base for the plaster must be primed. The first layer is leveling, its thickness is from 2 to 4 cm. Its task is to hide obvious surface defects: seams in masonry, cracks.
The next layer of plaster will have larger pores and its task is to evaporate moisture that somehow ends up in the wall. This layer will already be the finish for subsequent finishing.
If we talk about the most common mistakes when working with such plaster, then it is worth mentioning the need to slow down the drying process of the applied composition. If the room is hot, the plaster dries out too quickly, which can lead to flaking and cracking. To avoid this effect, you need to shade or cover the surface with a film. Or at least sprinkle with water during the day.
