1. Description - RubberCover Water Based Bonding Adhesive is used only for wet-mating Firestone RubberCover EPDM membranes onto acceptable wooden substrates.

2. Preparation - Surfaces that will receive the RubberCover Water Based Bonding Adhesive must be clean, smooth, dry, and free of sharp edges, loose and foreign materials, oil, grease, and other contaminants. The mating surface shall be cleaned with a brush or clean rag. If the product has been exposed to temperatures lower than 15°C for a prolonged period, restore the adhesive to room temperature (15°-25°C) before use. Stir the adhesive thoroughly (to achieve a uniform mix with no sediment on the bottom and no marbling evident) before and during use.

3. Application - RubberCover Water Based Bonding Adhesive will be mated, while still wet, directly over plywood or OSB substrates (only types that are not treated against water absorption). Apply Water Based Bonding Adhesive at a rate of approx. 350 gr/m² over plywood or OSB with a paint roller, taking care to completely cover the plywood or OSB substrate evenly to avoid globs and puddles of adhesive. The EPDM membrane shall be mated immediately after the bonding adhesive is applied by rolling the membrane in place over the plywood or OSB. To ensure proper adhesion, compress the bonded portion of the sheet to the substrate with a stiff push broom or heavy roller. Caution: The EPDM membrane should not be exposed to any wind stresses for 48 hours after mating. Moreover, the adhesive layer cannot be subjected to freezing temperatures for a minimum of 48 hours after the mating of EPDM to the substrate.

4. Coverage - Coverage rate needs to be between 2.5 and 3 m² per liter. Some surfaces are more uneven and porous and will result in lower coverage rates, while smoother substrates are less porous and will, therefore, result in higher rates
