CRYST ROOF® is a two-component, highly flexible, sealing coat with a very high special polymers content that penetrates into the pores of the substrate and seals it permanently to provide a flexible waterproofing of roof buildings. CRYST ROOF® consists of a cementitious powder component (component A) and low viscous rubber dispersion (component B). These two components chemically react when mixed to produce a firm, yet still highly flexible coating that can be simply applied by stiff brush, roller, spray or trowel to obtain the desired texture. It presents excellent bonding and elongation characteristics, which makes it an ideal solution for surface waterproofing under temperature variations, crack bearing, and moving surfaces.
