Silicate plaster

Silicate plaster is a structural coating material that is mainly applied as a final plaster to building materials and thermal composite systems. The plaster consists of (inorganic) silicates to which up to 5% (organic) synthetic resin ( emulsion paint ) is added in order to improve the color stability and the adhesive properties. The hardening of the wet applied plaster takes place with the carbon dioxide (CO ₂ ) from the air in a chemical conversion to calcium silicate and silica . This process, known as silicification , is also used for sealing in building technology. Silicate plaster is characterized by good water resistance and high water vapor permeability. This is why this type of plaster is preferred for monument maintenance. The technical and qualitative requirements are regulated in the European standard DIN EN 15824 “Specifications for external and internal plasters with organic binders”. The addition of the emulsion paint enables a wide range of color variations with diverse applications.
