Kelmore’s Waterproofing Paste is a ready to use, rapid drying, liquid membrane designed to protect moisture sensitive wall and floor backgrounds in wet areas prior to tiling. Used in conjunction with Kelmore’s reinforcing tape and preformed corners, this highly polymer modified paste, once dry creates an extremely flexible waterproof layer, protecting backgrounds from potential water damage. Only requiring a single coat application, this self-priming, quick drying product enables tiles to be fixed after only 3 hours.
