Analysis of the Degradation of External Plasters in the Buildings with ETICS

Article Preview

Abstract:

The external plaster are currently the most common finish coat of buildings. The characteristic technological and chemical properties of plasters protect supporting structure against weather and temperature extremes. Quality of plaster is determined by its durability, which depends primarily on the quality of raw materials, the quality and porosity of the substrate, the temperature during application, concentration of carbon dioxide and humidity of the ambient air. The physical and chemical and biological degradation of plaster is caused due to weathering and exposure to aggressive substances of environment. The paper deals with the analysis of the causes of degradation (green facades) and the possibilities of remediation of biotic attack of plasters buildings with External Thermal Insulation Composite System (ETICS).
