Professional Rapid Set Flex Grey by Larson is a flexible, non slip, fast setting cement based adhesive. It is ideal for fixing porcelain, ceramic and dark coloured stone tiles to the floor or wall in both interior and exterior locations. This adhesive can be used to fix tiles onto timber subfloors overboarded with 15mm exterior grade plywood along with heated screeds. The adhesive bed thickness can be 3-6mm with small isolated areas built up to 12mm. Gypsum Plaster must be sealed with Larson Acrylic Primer prior to the application of cement based adhesives.
