Utilizing the TUFFLEX - II Walking Deck System
A multi layered one-hour fire resistance-rated coating system for exterior walking roof deck surfaces. The system is applied over plywood substrates which have a minimum ¼ inch per foot slope for water drainage. Components of the system consist of galvanized expanded metal lath secured to the deck. A polymer reinforced underlayment mix known as TUFFCRETE is troweled over the metal lath. A layer of fiberglass matting is then bonded to the surface using TUFFLEX II Basecoat Resin. A texture coat of TUFFLEX II Texture Coat mixture is then applied followed by a pigmented sealer coat of TUFFLEX II Top Coat.
