What adhesive is Best for my Roof Deck?
For Porous Timber surfaces, Water Based adhesive for the main deck and Contact adhesive around the perimeter will be perfect.
For any of the other compatible surfaces such as tr27 insulation boards, GRP, Concrete or Metal, Contact adhesive should be used to adhere the entirety of the membrane to the deck.
Contact adhesive should also be used to adhere to any non-porous Timber surfaces and also on roof's over 100m2.
