RVshark RV Roof Sealant — 2-Pack White Self-Leveling Lap Sealant, Flexible & UV-Resistant

This two-pack of RVSHARK self-leveling lap sealant is formulated for RV owners and technicians who need a reliable, low-odor solution that cures to a flexible, weather-resistant surface. It bonds to common roofing materials like EPDM, TPO, PVC, aluminum and more, and is designed to remain flexible from -40°F to 200°F. Each tube includes upgraded accessories so you can finish jobs cleanly and quickly.

How quickly does the sealant level and cure?

The RVSHARK formula self-levels within about 30 seconds, turning a linear bead into a smooth, flat surface for horizontal seams. While surface leveling is rapid, full cure time depends on bead thickness and environmental conditions; thin beads cure faster than deep fills.

• Self-levels in ~30 seconds for a smooth finish
• Thin applications cure quicker than thick fills
• Workable window is short—apply and shape immediately

Will this sealant withstand sun, cold and heat?

The compound is engineered to remain flexible across a wide temperature range, resisting cracking from thermal expansion and contraction. It also incorporates UV-resistant properties to help maintain adhesion and appearance over time when exposed to sunlight.

• Flexible from -40°F to 200°F to handle extremes
• UV resistant to reduce sun-related degradation
• Designed for seasonal temperature swings without brittleness

What surfaces and applications is it compatible with?

RVSHARK bonds to many common RV and roofing substrates without a primer, making it suitable for skylights, vent surrounds, seams, roof edges and small gap repairs. It adheres to EPDM, TPO, PVC, metal, glass, mortar and wood, providing a single product for multiple repair tasks.

• Bonds to EPDM, TPO, PVC, aluminum, brass and steel
• Works on skylights, vents, seams and roof edges
• No primer required for most surfaces—clean application area first

How easy is it to apply and what comes in the package?

Designed for DIYers and pros, the sealant dispenses smoothly and self-levels, reducing the need for tooling. The two-pack includes replaceable nozzles and protective gloves so you can apply cleanly and maintain consistent bead shapes from tube to tube.

• Two tubes per pack with replaceable applicator nozzles
• Protective gloves included to keep hands clean during work
• Low-odor, safe formulation suitable for indoor or outdoor use
