• Elevate Bonding Adhesive can be used to Bond your Rubber membrane to a variety of surfaces, as well as your timber decking. This can include other wood surfaces, brickwork, stone (masonry), metal, & other suitable surfaces.
• The Bonding Adhesive is applied to both the surface & the folded back EPDM, which will mate to your surface. This provides a much stronger bond, though note, corrections are much harder (unlike the waterbased adhesive), so care must be taken when mating to ensure no wrinkles, creasing, or air pockets.
• You will need a 4'' or 9'' Roller Frame & sleeve, plus an Extension Roller for the application of the adhesive, which is designed to bond your EPDM to your timber deck surface only.
More can be found in the installation guides, but to summarise:
STEP 1. Ensure the surface is clean, dry and free of dust and other small particles. Sweep clean, use a either leaf blower, or other suitable method to remove any stubborn areas.
STEP 2. Fold back your EPDM approximately half-way. Then apply and even coverage of the Elevate Bonding Adhesive, avoiding areas of accumulation onto the mating surfaces. Apply about the same time onto both surfaces to be adhered, in order to allow approximately the same drying time.
Step 3: Allow the adhesive to flash off until tacky (time depending on ambient air conditions) before mating the surfaces. Test the adhesive for its dryness, using the touch-push test procedure.
Step 4: Mate the membrane with the surface, neatly smoothing into place. Note that once mating has been done, it is difficult to correct any bubbles, or wrinkles etc - so take care to mate evenly & straight, smoothing out as you go.
STEP 5. Smooth down with a soft brush or EPDM roller to remove any air pockets, bubbles and creases. Repeat for the remaining half.
Additional notes:
• Note Application temperatures may vary between 5°C and 35°C.
• At temperatures below 10°C, the adhesive may become too cold, while at temperatures above 35°C the membrane surface may become too hot and will shorten significantly the drying process.
• If a correction is to be made & the EPDM needs pulling back up, more Bonding Adhesive will need to be applied as the performance will have been affected. It is normal for the EPDM to be difficult to pull back up due to the strength of the bond.
• Some surfaces are more uneven and porous and will result in lower coverage rates, while smoother substrates are less porous and will, therefore, result in higher rates. Very porous substrates (rough wood, concrete block) may require an additional coat of Bonding Adhesive BA-2012 to ensure proper adhesion. This can be determined by adhering a small piece of membrane to the substrate and verify its bonding strength.
