On metal surfaces, remove grease and oil, if any, prior to applying the product. SUBSTRATE SBS modified bitumen membrane Concrete of fibrocement panels Wood and plywood Metal APPLYING RESISTOFLASH ADHESIVE Mix thoroughly before applying. Impregnate the surface to be prepared with adhesive using a brush or roller. Reinforce transitions and joints between two bases with RESISTOFLASH REINFORCEMENT membrane. Install immediately after the coat of RESISTOFLASH ADHESIVE. NOTES RESISTOFLASH ADHESIVE is designed to resist UV radiation and can remain unprotected. Do not spread more than 10 ft (3 m) at a time. APPLICATION AND CURING TIMES Once the RESISTOFLASH REINFORCEMENT has been installed, immediately cover with a first coat of RESISTOFLASH ADHESIVE. Cover the first coat with a second coat of RESISTOFLASH ADHESIVE after 2 to 3 hours. This curing time corresponds to the polymerization of RESISTOFLASH ADHESIVE at an ambient temperature of 68 F (20 C). Favourable conditions such as hot, humid, or windy weather can significantly reduce the curing time. OPTIONAL FINISHES Coloured granules: Small coloured granules can be spread on the last coat of RESISTOFLASH ADHESIVE while it is still wet. Use approximately 1.2 kg/m ². Spread the granules from bottom to top using a plastic trowel. The granules can also be added later by first spreading a thin coat of RESISTOFLASH ADHESIVE (250 g/m ² ) on the surface. Anticorrosion sealant: A coat of ANTICORROSION SEALANT (approx. 200 to 250 g/m²) can be applied to the surface for an aluminum finish. 1 Using a brush, roller, or spatula, apply a 4-in-wide (10 cm) coat of RESISTOFLASH ADHESIVE both horizontally and vertically at the bottom of the transitions between the roof and the upstands.
