Waterproofing Wood Decks
Decks live in wet, freeze-thaw, foot-traffic conditions, and the coating that protects them has to flex without cracking, shed water without ponding, and grip underfoot. HydroStop Traffic Coat is the GAF answer: a fabric-reinforced acrylic system in smooth and textured finishes, warranted for walkable surfaces.
For the full system: Base Coat plus HydroStop Fabric build the reinforced waterproof layer, then Traffic Coat finishes it (smooth for rooftop terraces and walkable membranes, textured for slip resistance under regular foot traffic). Pair with Premium Acrylic Flashing for transitions and details, GAF Cleaning Concentrate for surface prep, and GAF Repair Pro Sealant for fast field repairs.
This collection covers plywood and wood deck substrates. For deck waterproofing on concrete or structural slabs, see Concrete Waterproofing. Factory-direct from a GAF-authorized distributor.
