Specialists – distributors of technical examinations of buildings and structures came to the conclusion that now, during repair or construction work, such material as plastering waterproofing is used. Ordinary citizens who have knowledge of repairs at the level of “Blue wallpaper” or “paint the walls” are unlikely to ever hear about such waterproofing. But it is quite well known to specialists.
Plastering waterproofing, as a rule, is used for structures that are not subjected to deformations and vibrations. Among the advantages of this material, one can note the convenience and ease of application, the possibility of applying surfaces (even to a concrete or brick wall), environmental cleanliness, durability, as well as the possibility of applying any finishing materials to it – paint, stone, tiles, plaster, etc. p.
As the very first plaster waterproofing, 3 mm was used. cement that does not contain any fillers. Our great -grandfathers also used it for foundations for wooden log cabins and for cellars. Subsequently, the material changed, additives from ceresitis, sodium aluminum began to appear in the cement solution, the solution itself began to be made on liquid glass.
If we consider the above “additives” in more detail, then the following can be noted:
– Cerezite (this is an emulsion made of water, lime, ocher, oleic acid and alumina sulfate). When the cerezitis is added to the cement solution, they achieve an increase in the water resistance and density of the material.
– Sodium aluminum is used for the installation of waterproof screeds, sealing of the so -called oozing cracks and for the use of plaster on wet surfaces.
– Liquid glass also provides a cement solution with moisture protection and rapid grasping with the surface.
Nowadays, such solutions have lost their relevance due to the difficulty of compiling them. Preference is given to dry compositions and mixtures that are made at factories according to complex recipes, and which are very simple when kneading at home (mixed with ordinary water).
As mentioned above, plastering waterproofing consists of mineral binders (mainly cement), mineral and polymer additives, as well as from various fillers. It is intended for applying insulation layers in rooms with high humidity – bathrooms, showers, pools, basements, on balconies, roofs, etc. p. This waterproofing can be used both inside and out of the rooms on various surfaces. The material retains vapor permeability, but at the same time providing good protection against moisture.
For applying such a solution (no matter what kind and on which surface) there is one single common requirement. All surfaces should be cleared of dirt and dust, fats and oils, and other contaminants. This is very important, since experts in the inspection of the survey of buildings have repeatedly encountered defects caused directly by violation of the described technology.
