Approved for sundecks, Flexstone premium liquid coatings provide a sound, reliable layer of impenetrable protection that lasts a lifetime, regardless of where in Canada you live. In addition, it is the only liquid coating in Canada with full Canadian Construction Materials Centre (CCMC) approval as a waterproof seamless flat-roof membrane. A viable option to traditional waterproofing methods like torch-on and vinyl decking, Flexstone forms a bond with substrates like plywood or concrete when applied. The water-catalyzed urethane—which is 100 per cent UV-stable—can even be applied directly over top of old membranes or coatings. Further, Flexstone is thicker than any other liquid coating and is entirely seamless.
