RVshark RV Roof Sealant 4-Pack — 30s Self-Leveling White Sealant, UV & Temperature Resistant

RVSHARK RV Roof Sealant is a fast self-leveling, all‑weather white lap sealant in a 4‑pack designed to create flexible, waterproof seals on RV roofs and accessories.

Keep water out and movement in. This 30‑second self‑leveling formula spreads into a smooth, flat bead on horizontal seams and cracks, forming a durable, UV and temperature‑resistant barrier. It bonds to common RV roofing materials and comes with replaceable nozzles and protective gloves so you can repair leaks quickly and with minimal mess.

How quickly does it set and what does "self-leveling" mean?

The product flows out as a bead and evens itself into a flat, uniform layer within about 30 seconds on horizontal surfaces. This reduces the need for tooling and gives a neat finish even for less experienced users.

• Visible smoothing occurs within 30 seconds on flat seams.
• No extensive tooling required for horizontal gaps.
• Ideal for lap seams, roof edges, and flat joint repairs.

Will it hold up in extreme temperatures and sun exposure?

Yes — the formulation stays flexible and breathable from -40°F to 200°F and resists UV degradation. That range protects seals through seasonal temperature swings and prolonged sun exposure common to RV roofs.

• Maintains flexibility to prevent cracking in cold and heat.
• UV resistance slows breakdown from sunlight.
• Suitable for year‑round outdoor use on parked or traveling RVs.

What surfaces and repairs is it compatible with?

This white sealant bonds to materials frequently found on RVs: EPDM, TPO, PVC roofing, aluminum, steel, brass, glass, mortar, and wood. Use it for sealing around skylights, vents, seams, and any area where a waterproof finish is required.

• Bonds well to rubber, single‑ply membranes, and metal flashings.
• Works on interior and exterior joints where a flexible seal is needed.
• Good for small patch repairs and routine maintenance sealing.

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

The product is formulated for both DIYers and professional techs: cut the tip, apply a bead, and let it self‑level. The 4‑pack includes extra nozzles and a pair of gloves to reduce cleanup and extend usability.

• Includes replaceable nozzles for precise application.
• Low‑odor, safer formula permits indoor or outdoor use.
• Use soon after opening for best adhesion; observe production date on bottle.
