Dicor Lap Sealant helps create a watertight seal along a roof's edges, around air vents, vent pipes, air conditioners and screw heads. Compatible with EPDM rubber roofing, it offers excellent adhesion to aluminum, vinyl and galvanized metal. It improves the ability to continuously seal and remain flexible.
