What needs to be done before plastering surfaces
The use of building mixtures on the surface requires the preparation of the basis. Applying a layer of mixture of plaster without cleaning and processing the base of the base does not correspond to the technology.
Previously, the surface is thoroughly cleaned, on which, therefore, the mixture will be applied, and especially – not to mention dust – from fat and other significant contaminants. One of the features of modern finishing technology is the use of building primer mixtures, which improves adhesion, therefore, strength and operational characteristics. And if it is necessary to wash the surface of the base, it is necessary to give the surface time to dry, the same principle applies to the processing of the basis of the primer. You need to wait until the layer dries. Go to another stage.
