For safe, fast, durable installation, gypsum plasters and fillers are modified with VINNAPAS^® dispersible powders. WACKER dispersible powders improve ease of manual and mechanical application, enhance flexibility, reduce water absorption (VINNAPAS^® H) and produce smooth, non-cracking surfaces.

SILRES^® BS products play a special role in rendering plaster water repellent: these work by generating a silicone resin network that imparts excellent long-term stability to the building material through the formation of a chemical bond with the gypsum. SILRES^® BS reduces the level of water absorbed by the material while retaining water-vapor permeability.
