Firestone Bonding Adhesive Method of Application

Surfaces on or against which Firestone Bonding Adhesive is to be applied must be clean, dry, free of foreign materials and excess dusting agent. Clean with broom or rags if necessary.

Stir Bonding Adhesive thoroughly before and during use, achieving a uniform mix with no sediment on the bottom and no marbling evident. Apply Bonding Adhesive with a solvent resistant paint roller and roll at about the same time to both the underside of the EPDM pond liner and the substrate to which it will be adhered to allow approximately the same flash off time. Apply Bonding Adhesive evenly to avoid globs and puddles of adhesive. Bonding Adhesive may also be spray-applied, followed by rolling to ensure 100% coverage of the Bonding Adhesive. Care must be taken not to apply Bonding Adhesive over any area that is to be later cleaned and spliced to another sheet or flashing.

Allow the Bonding Adhesive to flash off completely according to the touch-push test (usually less than 15 minutes, flash off time will vary depending on ambient air conditions).

Starting at the fold, roll the previously coated portion of the EPDM pond liner into the coated substrate slowly and evenly so as to minimize wrinkles. To ensure proper contact, compress the bonded half of the EPDM pond liner to the substrate with a stiff broom using heavy pressure.

Firestone Bonding Adhesive Coverage Rate

Approximately 45-60 square feet per gallon may be obtained depending on the substrate. Some surfaces are more uneven and porous and will result in lower cover rate while smooth, non-porous surfaces may result in higher coverage rates. Rates are based on roller application to both mating surfaces. When sprayed and back-rolled, the coverage rate may be slightly higher than when rolled only.
