Mineral plaster: composition, photo, application technique

Mineral plaster is a natural, environmentally friendly material, which is a dry building mixture, which is used for both internal and external works.

The composition of the mineral plaster and its application

Mineral plaster is made on the basis of lime hydrate, marble granulate, high-quality white Portland cement and light mineral aggregates. Such plaster is very economical in costs and is well suited for thermal insulation of a building. Although the plaster contains lime that does not tolerate water, the material itself can be safely cleaned and washed, since it is based on substances that prevent lime from "melting".

The material is intended both for interior decoration and for facade work. By the way, during facade work, plaster is often used in an external thermal insulation system. Mineral decorative plaster is not picky in work and it can be applied on any mineral substrates, including gypsum plasters, asbestos cement, plywood, fiberboard, particleboard, concrete and gypsum board. But still, the mixture is best suited for walls that are subject to abrasion or have a protruding surface (entrances, stairwells, corridors, etc.) as well as for the basement of buildings.
