Thirdly, hides irregularities and some wall defects.
The names of decorative plasters on a water basis can be all kinds. As already mentioned, they can be: acrylic, butadiene-styrene dispersions, polyvinyl acetate and others. In addition, each manufacturer, producing a particular product, gives its name.

- Mineral plasters are excellent for thermal insulation of facades. Made of fully environmentally friendly raw materials and suitable for both indoor and outdoor decoration of premises. The composition includes: lime hydrate, white portland cement, marble granules, light mineral aggregates.
- Venetian plasters or else they are called "liquid marble" recreate the inimitable coloring of the Venetian palaces. That is why this name. These types of decorative plaster are used in almost any interiors. The house with such plaster looks like an antique palace.
- stone plasters are a mixture of marble, quartz or granite chips, to which adhesive binders are added on an adhesive basis.
