What Surfaces Can I Bond ClassicBond EPDM To?
ClassicBond EPDM is best bonded onto timber surfaces such as roofing grade plywood or OSB3 (Oriented Strand Board) sometimes called sterling board.
ClassicBond can also be bonded to lightweight concrete and other non-porous surfaces such as Fibreglass and tissue faced insulation.
What Surfaces Can Not Be Bonded To?
ClassicBond EPDM can not be bonded to bituminous surfaces such as:
- Roofing felt
- Asphalt
- Liquid mastics
The EPDM will tend to draw the oils out of the bituminous material which causes the EPDM to lose its molecular structure and fail. Care should be taken when removing the old Bituminous roofing membrane as it may leave a residue that can damage the EPDM membrane. We normally recommend over boarding old roof coverings using an OSB3 recovery board or insulation boards.
