Biostability of Plastering Systems in Buildings and Structures
Vertical enclosing structures of buildings and structures made of stone materials are often in difficult operating conditions. This is due to: humid and wet conditions of premises and an aggressive production environment in industrial buildings; violation of the composition of building materials with an excess of the content of hygroscopic salts in the feedstock or additives to concrete and mortars; deviation of microclimate parameters in residential and public buildings from standard values. Plastering compounds applied to the surface of the walls inside the premises, in such buildings, can be stained with efflorescence and mold. Due to the hygroscopic effect, salts attract atmospheric moisture. Waterlogged material is a favorable environment for the development of spores of various types of filamentous fungi. Therefore, the plaster layer undergoes salt and biological corrosion, which reduces the strength properties of the material and violates the decorative qualities of the interior finish due to peeling of the plaster, peeling and destruction of paint layers. The study investigated the biological resistance of samples of plaster systems for interior decoration of premises to the action of filamentous fungi of various types, adopted for such studies as a test culture. The influence of various types of primer, filler and color on fungal resistance, fungicide and physical and mechanical properties of plaster systems was revealed. It has been established that plaster systems, consisting of layers of materials with water-repellent properties and biostability, provide comprehensive protection against the effects of salts and bio-contamination. The required aesthetic qualities of plastering systems from the room side are provided by applying decorative plaster or painting.
