This 25-pack of 10.3 oz tubes offers sun-ray stabilized, waterproof protection that won’t discolor or damage roofing materials.

## Description

Dicor’s Self-Leveling Lap Sealant creates a watertight seal along a roof's edges, air vents, vent pipes, and screw heads. This lap sealant is a versatile sealant formulated for EPDM roofing but also compatible with most other roofing material, including Dicor DiFlex II, Tufflex PVC, 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 sun-ray stabilized to stop discoloration and decline and will not stain or discolor any material to which it is applied. HAPS-free.

Review: Great Product at the Right Price! - Dicor is the go-to for roof RV sealing. I own an RV repair company and we buy this case often! Always dependable. Tubes work great and don’t leak when applying. It levels out just right and for the price you just can’t beat this! Highly recommend!
Review: great stuff, great value. - the roof membrane on my 1996 allegro bay needed to be replaced and after getting hit with the $14k estimate from a local repair shop (which is almost triple of what i paid for the RV to begin with..) i decided to look at replacing it myself and i ended up doing it myself with the help from my brother for about $2k. this 25 case is a better value than buying it 1 at a time or even a case of 12. that leaves each tube at about 7 bucks each. it’s exactly what you’d expect and wasn’t dried up or anything thanks!

### ⭐⭐⭐⭐⭐ highly recommend, we're professionals
*by S***B on April 12, 2025*

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.
