Complete Step By Step installation guide and video for our One-Piece Classic Bond EPDM Rubber Roof Kits
Roof Deck Preparation
Clean the roof surface prior to installation
Be sure the roof surface is clean, free of dust, dirt, rust, oil, grease, and loose material. The roof surface must be dry. This product will not adhere to wet surfaces. Trapped moisture may vaporize and negatively affect the performance of this product. This system can be laid over old felt, asphalt or deck boards where the felt has been completely removed.
Any residual Bitumen from an old roof that is tacky and non-oxidised must either be removed or over boarded as this will adversely affect the performance of the EPDM rubber membrane.

Apply Deck Adhesive
Apply Water Based Deck Adhesive using a 9" paint roller. Leave a 150mm un-bonded area around the roof deck perimeter for bonding later with Contact Adhesive
Roll the EPDM membrane back in to position immediately whilst the adhesive is STILL WET
If the adhesive dries out (becomes opaque) before the membrane is relayed then a thin coat can be applied to the back of the MEMBRANE and allowed to dry before installing. Apply adhesive to smaller area in hot whether to avoid premature drying.
(Water based adhesives should only be used when the outside temperatures is 4 degrees and rising and no chance of freezing conditions in the following 24-48 hours)
Sweep EPDM Membrane
Apply Contact Adhesive to Roof Perimeter
Apply a THIN coat of Contact Adhesive to the roof deck perimeter (approximately 150mm width) and any vertical upstands. Also apply the Contact Adhesive to the back of the rubber membrane.
Contact Adhesive can also be used to bond the rubber membrane to most porous and non-porous surfaces so can be used in place of water based deck adhesive if necessary
Ensure Contact Adhesive is Touch Dry
Ensure the Contact Adhesive is touch dry and there are no puddles of adhesive.
The Contact Adhesive gives off a vapour as it cures. If the membrane is bonded before the Contact Adhesive has fully dried bubbles/blisters may appear. These bubbles should disappear over time due to the EPDM membrane being breathable.
