Firestone Water Based Adhesive



Firestone Water Based Adhesive WBA-3781 is designed for bonding Firestone EPDM to Timber surfaces.


Bonding surfaces must be clean, dry, smooth, free of sharp edges, loose and foreign materials, oil, grease and any other contaminents.


Stir adhesive thoroughly before and during use. Use only when temperatures will not fall below freezing at anytime 24 hours after mating 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 globs and puddles of adhesive. The EPDM may be Wet-mated 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.

Firestone Water Based Adhesive Must Be Used Onto Timber

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. The reasons why Waterbased / Deck is often used is because it is easy to lay, you can lay the EPDM straight onto it while it is still wet and it is also possible to correct mistakes shortly after the EPDM has been laid down up to 2-3 times if you find there is unwanted debris underneath due to it taking slightly longer than bonding to dry.
