Kohree RV Roof Sealant — Self-Leveling Lap Sealant 4-Pack White, Waterproof Flexible Seal

Kohree RV Roof Sealant is a self-leveling, waterproof lap sealant in white designed to create flexible, long-lasting seals on RV roofs and a variety of outdoor surfaces.

When leaks, seams or small cracks appear on camper roofs, a fast-curing, easy-applied sealant that adapts to temperature shifts is essential. Kohree’s self-leveling lap sealant comes in a convenient 4-pack and is formulated for low odor, indoor/outdoor safety, and broad adhesion to common roof materials—so you can mend seals on EPDM, TPO, PVC, metal and more without complex tools.

How quickly does Kohree self-level and form a smooth seal?

The formula is engineered to flow and smooth itself within about 30 seconds after application, converting a bead into a flat, continuous surface that better covers gaps. That reduces the need for tooling and helps create a uniform waterproof layer across seams and cracks.

• Self-levels in roughly 30 seconds for a flat finish
• Reduces visible ridges and uneven gaps
• Speeds up repairs by minimizing post-application tooling

Which materials and areas will this lap sealant bond to?

Kohree bonds to a wide range of substrates you commonly find on RVs and trailers: EPDM, TPO, PVC roofing membranes, aluminum and steel trim, plus glass, wood and mortar. This versatility makes it useful for roof seams, vents, flashing, and other trouble spots across the vehicle.

• Compatible with EPDM, TPO, and PVC roofing
• Adheres to metals like aluminum and steel, and non‑metal surfaces
• Works on vents, seams, flashing and small patch repairs

Is it suitable for all-weather use and temperature changes?

Yes—the sealant remains elastic and breathable across a wide temperature range, helping prevent cracking when the roof expands and contracts. It’s rated to perform from -40°F up to 200°F, making it appropriate for hot summers and freezing conditions often experienced by RVs.

• Rated working temperatures: -40°F to 200°F
• Elastic formula resists surface cracking with temperature shifts
• Designed for longer service life without frequent re-sealing

How safe and easy is it to use inside or outside the RV?

The product uses a low-odor, low-hazard formula, so it can be applied in ventilated indoor spaces as well as outdoor roof work. Standard caulking application techniques apply—cut tip, apply bead, and let it self-level—making it accessible for DIYers and pro installers alike.

• Low odor and formulated to be safe for humans and pets when used as directed
• Simple cartridge application—cut nozzle, apply bead, allow to level
• Best used soon after opening; production date printed on bottle
