Recommended Application
Clean surface spit is free from loose concrete, stone, mortar, foreign materials and other contaminates.
Apply a 3/8" to 1/2" bead of the water block to the substrate surface. Bring the second surface of the EPDM pond liner into contact with the Water Block Seal. Roll or press the EPDM pond liner firmly against the Water Block Seal avoiding wrinkles and air bubbles. See complete detail on Firestone Specialty Products specifications and details.
