Kohree RV Roof Sealant 8-Pack White — Self-Leveling Lap Sealant, Waterproof Flexible Bond

Kohree RV Roof Sealant 8 Pack is a self-leveling white lap sealant designed to create waterproof, flexible seals on RV roofs and other surfaces quickly and cleanly.

When you need a fast, reliable way to stop leaks and seal gaps on an RV roof, the Kohree self-leveling lap sealant is formulated for that job. It levels out within seconds to form a smooth, continuous bead that adheres to a wide range of materials—EPDM, TPO, PVC, metal, glass, wood and more—so you can patch seams, punctures and flashing without extensive prep or specialized tools. The low-odor, non-hazardous formula lets you use it in outdoor or semi-enclosed spaces, and its elasticity helps resist cracking across temperature swings.

How quickly does this sealant level and form a waterproof seal?

Within about 30 seconds the Kohree lap sealant changes from a linear bead to a flat, uniform surface that fills and covers cracks or seams. That rapid self-leveling minimizes tooling and creates a continuous barrier that resists water intrusion.

• Self-levels in ~30 seconds for a smooth finish
• Forms an adhesive, waterproof barrier on application
• Reduces the need for tooling or smoothing by hand
• Suitable for sealing seams, gaps, and large cracks

Which materials and surfaces will this lap sealant adhere to?

The formula bonds to common RV roof membranes and structural materials, making it versatile for repair and maintenance. It’s compatible with EPDM, TPO, PVC and a variety of metals and substrates found on campers and trailers.

• Works on EPDM, TPO, PVC roofing membranes
• Adheres to aluminum, brass, steel and glass
• Also bonds to mortar, wood and many other building materials
• Good for patching penetrations, seams, and flashing details

What weather and temperature conditions can it withstand?

Kohree’s RV sealant is formulated for broad temperature performance and long-term flexibility. It stays elastic across wide temperature swings so joints expand and contract without cracking the seal.

• Operating temperature range: -40°F to 200°F
• Elastic and breathable—maintains integrity through freeze/thaw
• Designed for outdoor exposure on roofs and exterior surfaces
• Resists frequent resealing due to durable service life

Is this safe to use around people and pets, and how easy is cleanup?

The sealant uses a low-odor, non-hazardous formula intended for safer handling than many solvent-heavy alternatives. Basic precautions—gloves and ventilation—are still recommended, and uncured material can typically be removed with appropriate cleaners.

• Low odor, kinder for indoor or shaded work areas
• Non-hazardous formula reduces strong chemical fumes
• Clean uncured seals with manufacturer-recommended solvent or cleaner
• Follow normal safety steps: gloves and eye protection
