How to properly install and seal an RV roof vent using Dicor lap sealants. EPDM Lap Sealant creates a secure, secondary seal along the roof's edges, air vents, vent pipes and screw heads. Compatible with EPDM, TPO and DiFlex II roofing, it adheres firmly to aluminum, mortar, wood, vinyl, galvanized metal, fiberglass and concrete. Ideally suited for aftermarket use. Dicor Lap Sealants are color matched and are UV stabilized to prevent deterioration and discoloration. Plus, they will not stain or discolor any roofing material to which they are applied.
