KEIM Granital Grob is a primary coat and filler for the KEIM Granital system which reacts chemically with the surface. It should be used as a bridging coat on previously painted surfaces or to bridge hairline cracks and equalise the surface.
The system offers water repellency, vapour permeability and forms a chemical crystalline bond with the substrate. KEIM Granital Grob is made using pure inorganic mineral fillers, earth oxide colour pigments and potassium silicate binder.
