Dicor Products Lap Sealant is a versatile sealant formulated for EPDM roofing but also compatible with most other roofing material, including Dicor DiFlex II™ and BriTEK™ TPO roofing. It offers excellent adhesion to aluminum, mortar, wood, vinyl, galvanized metal and concrete. Continuously seals and remains flexible. Color-matched, our lap sealants are UV stabilized to prevent discoloration and deterioration and will not stain or discolor any material to which it is applied.
