## 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 avoid discoloration and spoiling and will not stain or discolor any material to which it is applied. HAPS-free.

Review: Works well on trailer roofs - This is a good product. We have a lot of client's in a vacation park. Their park model trailers take a beating all winter and then get cooked in the sun all summer. This is the best sealant I've found for tpo and rubber roof that trailers have. It is easy to apply and makes a nice solid patch.
Review: The Only Lap Sealant I Use! - I have tried a couple of other brands of lap sealant, and the results were simply not good. I recently installed an additional solar panel on my RV. I used a cheaper brand to save a few dollars, huge mistake! So, I decided to order Dicor and used it to finish the project and cover the other brand. The Dicor flows smoothly, it adheres great and the leveling is superb. It makes the project looks so much more professional, and I trust that it will do its job to seal and protect from leaks, etc. No more trying other brands, Dicor is the only lap sealant I will use in the future.

### ⭐⭐⭐⭐⭐ Great product
*by E***Y on March 27, 2026*

Works excellent for rv roof. Levels nicely and creates a flexible water tight seal perfect for covering screws and going around objects like the antenna and satellite or anything else that would make using sealing tape a pain in the rear. Have used it many times and will continue to use it when needed.
