It is commonly used in the TUFFLEX Specifications for protecting concrete and plywood pedestrian walking decks—including hard usage ski resort sun decks, vehicle parking decks, mechanical equipment room waterproofing and as a under tile waterproofing membrane. (For use on plywood decking systems it is also recommended that you refer to the TUFFLEX Solvent Free “SOFT” Technical bulletin for further information.) It is also used to provide seamless and cushioned membranes and mats over porous concrete in veterinary and locker room areas.  This material is also widely used to provide seamless and flexible waterproofing and rustproofing decking systems on ships. TUFFLEX Solvent Free Systems allow for ease of application in interior areas aw well as exterior areas. Refer to the TUFFLEX Specifications for further information and ideas.



a) All surfaces to receive TUFFLEX SOLVENT FREE “TUFF” must meet all applicable building and safety codes in the prescribed city, county or state, which ever has jurisdiction. Substrate must be structurally sound and sloped for proper drainage (see TUFFLEX Guide Specifications for complete information). NO LIABILITY IS ASSUMED BY MANUFACTURER FOR SUBSTRATE DEFECTS.

The substrate must be cleaned to ensure that it is free for all oils, “laitances”, greases and other contaminations, such as concrete curing compounds, that may cause poor adhesion of TUFFLEX SOLVENT FREE “TUFF”. After cleaning, the surfaces should be rinsed thoroughly to remove loose particles and traces of the cleaning membranes. The mixed and catalyzed membrane should not be applied until the surface is dry.
