RVSHARK RV Roof Sealant, 2 Pack

RVSHARK RV Roof Sealant is a fast-setting, self-leveling white lap sealant sold as a 2-pack to quickly form waterproof, flexible seals on RV roofs and horizontal joints.

Keep leaks out and drive with confidence: this 2-pack of RVSHARK 30S self-leveling sealant is formulated to turn a bead into a smooth, flat finish within 30 seconds so you can seal horizontal gaps, roof seams, and appliance bases without troweling or smoothing. The white, low-odor compound bonds to common RV roof materials and stays flexible across extreme temperatures, making it a practical solution for routine maintenance and emergency repairs.

How fast will this sealant set and how does self-leveling help?

The 30S formula begins to self-level almost immediately, transforming from a raised bead into a smooth, even film in about 30 seconds. That rapid leveling reduces hand finishing time and produces a cleaner, more professional-looking result on horizontal surfaces.

• Self-leveling action flattens beads within ~30 seconds
• Reduces need for tooling or smoothing
• Ideal for horizontal seams, roof laps, and skylight bases

Will it withstand weather, temperature swings, and UV exposure?

RVSHARK designed this sealant for wide temperature tolerance and long-term flexibility. It remains breathable and resistant to cracking from -40°F to 200°F and includes UV-resistant properties to help preserve the seal under sunlight and changing conditions.

• Temperature range: -40°F to 200°F
• UV-resistant formula to reduce sun degradation
• Maintains flexibility to handle roof movement and vibration

What surfaces and repairs is this compatible with?

This white lap sealant bonds to most materials found on RVs and trailers, letting you use a single product for vents, seams, and small roof repairs. It adheres to EPDM, TPO, PVC, metal, glass, mortar, and wood, so you can address skylights, rooftop antennas, seams, and edge flashings without switching sealants.

• Bonds to EPDM, TPO, PVC, aluminum, brass, steel, glass, mortar, wood
• Good for sealing vents, seams, skylights, roof edges, and trim
• One product for routine maintenance and spot repairs

How easy and safe is it to apply for DIYers?

Application is straightforward for both beginners and experienced users: cut the nozzle to the desired bead size, apply to a clean dry surface, and allow it to self-level. The kit includes replacement nozzles and protective gloves, and the low-odor formulation makes it suitable for use around living areas when ventilation is reasonable.

• Includes replaceable nozzles and a pair of protective gloves
• Low-odor, safe-for-use formula for indoor/outdoor tasks
• Best performance when used immediately after opening
