Description
Bonding EPDM to the deck is the step that decides whether a rubber roof stays put for decades or lifts in the first storm. FlexiProof EPDM Contact Bonding Adhesive is a solvent-based contact adhesive for fixing EPDM membrane, upstands and trims to timber decks, blockwork and other non-porous substrates: coat both surfaces, let them reach touch-dry, then bring them together for a permanent, high-strength bond.
- Solvent-based contact adhesive for full membrane bonding — perimeters, upstands and vertical details
- Suitable for one-piece and fleece-backed EPDM systems
- Three sizes to match your roof area

Frequently asked questions
How much do I need? At 1–2m² per litre, a 5L tin covers roughly 5–10m² of bonded area. Contact adhesive is typically used on perimeters and upstands rather than the whole deck, so measure those areas rather than the full roof.
Contact adhesive or deck adhesive? Use contact adhesive for perimeter zones, upstands and any vertical surface. For bonding the main field of the roof on large areas, a water-based deck adhesive is the usual partner product.
How long until it's ready to bond? Coat both surfaces and wait until touch-dry — tacky but not stringy — then press the membrane in firmly. Timing varies with temperature and humidity.
Is this a tape primer? No — for prepping EPDM ahead of pressure-sensitive flashing tape or corner patches, use our FlexiProof EPDM Rubber Roofing Primer instead.
Finishing the roof edge? Pair with our uPVC gutter drip trim and 1.2mm EPDM membrane.
