Firestone Water Based Bonding Adhesive

 

 

Firestone Water Based Bonding Adhesive WBA-3781 is used to attach your EPDM membrane to permeable decks - ply or OSB. It is suitable for roofs up to 100m2 and must be installed with a 150mm perimeter strip of Contact Adhesive around the outside. Non-porous roof decks (or those of low vapour permeability, e.g. metal or PU foam), upstands and trim work require the use of P150 or Contact Adhesive.

Why choose Water Based Adhesive?

Water Based EPDM Adhesive is a solvent free adhesive with low odour making it safe for use in most environments. It is a cost-effective solution, quick and easy to apply using a roller, and allows for correction after laying of the membrane as it does not instantly dry.

Suitable For:

Use with any of our roofing membranes. 
Bonding EPDM to wooden decks: fibreboard, chipboard, plywood. 
Bonding EPDM to concrete.
