Kohree RV Roof Non-Sag Sealant 2-Pack — White lap sealant for vertical & overhead seams, UV-resistant flexible bond

Kohree Non Sag RV Roof Sealant (2-pack) is a white, non-leveling lap sealant designed to create waterproof, flexible bonds on RV roofs and vertical joints without sagging or run-off.

Keep your RV watertight with a sealant made for overhead seams, lap joints and vertical repairs. This two-tube kit offers a low-odor, non-sag formula that adheres to rubber, PVC, metal and more. It cures to an elastic, UV-resistant finish that resists cracking as temperatures and vehicle movement flex the roof surface.

How does this sealant perform on overhead and vertical seams?

The Kohree non-leveling compound is formulated to grip and stay where you apply it, so it won't drip off vertical walls or pooled seams on an RV roof. Its paste-like consistency allows precise bead placement and maintains shape until it skins over and cures.

• Non-sag texture for overhead and vertical applications
• Strong adhesion to EPDM, TPO, PVC and metals
• Quick skin formation for fast, tidy repairs

What surfaces and materials will it stick to?

This sealant bonds to a wide range of common RV materials, making it a versatile choice for multiple repair points. It works on synthetic roof membranes as well as painted and bare metals, glass and wood trim when prepared properly.

• Compatible with EPDM, TPO, PVC roofing membranes
• Adheres to aluminum, brass, steel and glass
• Also suitable for mortar, wood and many building materials

Will the seal last through weather and movement?

The cured bead remains flexible and breathable, allowing the seal to expand and contract with temperature shifts and normal RV movement. UV resistance and color stability help prevent yellowing and surface breakdown over time.

• Elastic finish resists cracking during temperature changes
• UV-resistant to minimize discoloration and degradation
• Designed for long service life without frequent resealing

Is it safe and easy to use inside and outside the RV?

Kohree's low-odor, non-toxic formula makes it suitable for both exterior patching and interior trim repairs when ventilation is available. The paste stays put for neat application and dries quickly so you can resume use sooner.

• Low odor, safe for indoor and outdoor use with normal precautions
• Easy-to-tool consistency for neat beads and joints
• Recommended to use contents soon after opening for best performance
