SabreGrip R71 is a non-chlorinated, polyurethane spray adhesive, designed to be applied single sided to the roof deck only. It has been specifically designed for bonding all fleece-backed single ply membranes including TPO/FPO, EPDM and PVC, to various roof decks such as insulation boards, concrete, plywood, cementitious boards and existing asphalt/bituminous surfaces. SabreGrip R71 sprays in a unique snowflake spray pattern, designed to give a slight foaming effect to droplets on the surface so that the adhesive keys with the fleece or scrim backing in the membranes for optimum adhesion performance.
How to Use
- Substrate Preparation
Make sure that surfaces are clean, dry and free from dirt, dust, oil, loose paint, wax or grease, etc.
- Spraying the Adhesive
Spray about 15 – 30 cm away at a 45-degree angle to the surface, applying a uniform,
even coat of adhesive to obtain 60% to 80% coverage of the surface. If necessary, spray another coat of adhesive in areas that appear to need more adhesive.
- Tack Time:
Allow 1 – 2 minutes for the adhesive to tack off, make sure to apply membrane within 10 minutes of applying adhesive.
Adhere surfaces and press together with adequate pressure. A roller is recommended to apply a uniform pressure to achieve maximum strength. Allow 24 hours for the adhesive to fully cure.
If the spray tip clogs, unscrew the spray tip from the gun and clean with solvent such as lacquer thinner or acetone. Do not use a pin on the spray tip.
