FIRESTONE RUBBERCOVER WATER BASED BONDING ADHESIVE
Firestone Water Based Adhesive WBA-3781 is designed for bonding Firestone EPDM to Timber surfaces.
Preparation Bonding surfaces must be clean, dry, smooth, free of sharp edges, loose and foreign materials, oil, grease and any other contaminants.
Application: stir adhesive thoroughly before and during use. Use only when temperatures will not fall below freezing at any time 24 hours after matching of EPDM. Apply WBA-3781 over plywood or OSB substrates with a solvent resistant roller, taking care to completely cover the substrate evenly to avoid pooling. The EPDM may be wet-matched to the coated plywood or OSB by rolling the membrane in place over the substrate. To ensure proper adhesion, compress the bonded portion of the sheet to the substrate with a stiff broom or heavy roller, such as a linoleum roller.

A quick FAQ: we often have customers ask what the difference is between Bonding Adhesive and Waterbased/Deck Adhesive. Bonding adhesive is a much stronger adhesive which is used for bonding to most materials as well as wood and used around the edges of the EPDM, on any up-stands, bonding to brickwork etc where an effective and quick hold is required to keep the EPDM in place. Bonding adhesive is applied to both the EPDM and the surface.
Deck Adhesive/Waterbased Adhesive is more suited to wood and ply adhesion on the main area of the deck. It is often used is because it is easy to lay, the EPDM can be laid straight onto it while it is still wet, and it is also possible to correct mistakes, up to 2-3 times if you find there is unwanted debris underneath due as the Waterbased Adhesive takes slightly longer than the Bonding Adhesive to dry.
