It offers excellent adhesion to aluminum, mortar, wood, vinyl, galvanized metal and concrete. Continuously seals and remains flexible. Color matched, our lap sealants are sun-ray stabilized to stop discoloration and decline and will not stain or discolor any material to which it is applied. HAPS-free.

Review: highly recommend, we're professionals - We order this on a regular basis. We own and operate a mobile RV repair business and this is really the only brand we buy. We've tried other brands when we needed something quick, but the Dicor works the best. It's the easiest to apply, the best self-leveling action, the longest lasting adhesion. We use it for reseals and re-coating and tell customers to expect it to last 2-5 years with proper maintenance.
