Firestone Splice Adhesive is designed for splicing PondGard EPDM Pond Liners and Firestone 45 mil EPDM Pond Liners and adhering to a variety of surfaces as indicated in the Firestone Specialty Products specifications and details manual.
Recommended Method of Application
Position the EPDM pond liner to overlap 3" to 6" along the entire length of the splice. Fold the top sheet back and clean the dry both surfaces per Firestone Specialty Products specifications and details.
Stir the Firestone Splice Adhesive thoroughly before and during use, achieving a uniform mix with no sediment on the bottom and no marbling evident. Apply the Firestone Splice Adhesive with a 3" or 4" thick solvent-resistant paint brush to both mating surfaces at about the same time so as to allow approximately the same flash off time. Apply in a thick, even, smooth coat with long painting type strokes so that the brush marks bleed out, yielding a smooth, glossy adhesive surface. (Make one short backstroke at each field and factory cross seam to leave extra adhesive at the step off.)
Do not use circular motions, paint rollers, spray equipment or mechanical equipment for the application of splice adhesive.
Allow the solvents in the Splice Adhesive to flash off completely according to the touch-push test (usually less than 30 minutes, flash off time will vary depending on ambient air conditions).
Once the Splice Adhesive has dried, allow the top sheet to fall freely on the bottom sheet so as not to stretch or wrinkle the EPDM pond liner. Roll the entire lap splice using a 2" silicone or silicone-sleeved steel hand roller with positive pressure towards the outside edge of the lap, and along the entire length of the lap. Apply seam edge treatment in accordance with Firestone Specialty Products specifications and details.
