Fibre reinforced silicone resin paint with quartzite fillers and crack filling properties Because of its characteristic properties, Remmers Silicone Resin Filling Paint LA is suitable for water repelling, highly water vapour permeable, protective coatings on mineral building materials, especially when used in combination with Impregnation Primer. It can be used as a primer on load-bearing silicate and silicone paints as well as matt dispersion paints. It is also suitable as a filling, intermediate coat for levelling differing roughness on the surface of render (so called render pockets).
