Liquid Rubber RV Roof Sealant — White 1 Quart elastomeric waterproof coating, flexible heat-reflective finish

Liquid Rubber RV Roof Sealant is a professional-grade, white elastomeric coating that creates a flexible, waterproof membrane for camper and trailer roofs.

Designed for travel trailers, motorhomes, pop-up campers and utility trailers, this water-based roof coating forms a durable, heat-reflective layer that reduces solar heat gain and stops leaks. It works on a variety of surfaces—EPDM, TPO, fiberglass and metal—and is formulated for easy home application with brush, roller or sprayer. Use it with Liquid Rubber primers and seam products for a complete roof protection system.

How does this sealant stop leaks and stay flexible?

The coating cures to an elastomeric membrane that stretches and rebounds with roof movement, sealing gaps and hairline cracks without becoming brittle. Because it’s water-based and designed for temperature variation, it retains elasticity in cold and hot conditions, helping maintain continuous waterproofing.

• Forms a continuous, seam-free layer that prevents water intrusion
• Remains flexible across a broad temperature range
• Compatible with common RV roof materials when used with recommended primer

Will it keep my RV cooler in summer?

The bright white, reflective finish lowers the amount of solar heat absorbed by the roof, which can help reduce interior temperatures and ease cooling load. Reflective performance depends on surface preparation and coating thickness, so follow coverage recommendations for best results.

• High solar reflectivity reduces heat absorption
• Apply recommended coats to maximize reflective benefit
• Works best combined with overall roof maintenance and insulation

What surfaces and repairs is this suitable for?

This formula is formulated to adhere to EPDM, TPO, fiberglass and aluminum after proper cleaning and priming. It’s intended for whole-roof coatings, patching worn areas, sealing vents, skylights and transitions when used with seam tape and lap sealant.

• Use EPDM & TPO primer for improved adhesion on rubberized roofs
• Pairs with Liquid Rubber Lap Sealant and Seam Tape for joints
• Safe for vents, skylights, and camper awnings when applied correctly

How long does a typical project take and how much will I need?

Many DIYers complete an RV roof restoration over a weekend using the three-step system: cleaner, primer (if required), then the roof coating. Coverage is roughly 50 sq ft per gallon for the recommended film thickness; a full 1–5 gallon pail is sufficient for a 30-foot RV when applied as directed.

• Weekend-appropriate sequence: clean → prime → coat
• Estimate: 1 gallon per 50 sq ft for final thickness
• Store unused, sealed containers above freezing for touch-ups

Who this is for: Owners and technicians who want a long-lasting, water-based roof coating that combines leak protection, thermal performance and compatibility across common RV materials. It’s suited to DIY enthusiasts wanting professional results without specialized equipment, fleet managers maintaining multiple units, and anyone aiming to extend roof life while preserving a white, reflective finish. Follow the manufacturer’s surface prep, primer and application instructions for durable results and use seam tape and lap sealant at movement-prone joints.
