Liquid Rubber RV Roof Sealant — White 1 Gallon, Elastomeric Waterproof Coating UV-Reflective Flexible

Made to protect RV roofs from leaks, UV exposure, and temperature swings, this one-gallon formula rolls on like paint and cures to a durable, elastic layer. It works across common RV roof materials—EPDM, TPO, fiberglass, and aluminum—and pairs with Liquid Rubber primers and seam products for a complete roof protection system. The product is zero-VOC and designed for DIY application with brush, roller, or sprayer between 50°F and 90°F (10°C–32.2°C).

How does this sealant stop leaks without cracking in changing weather?

The coating cures into an elastomeric membrane that stretches and recovers, so it follows roof movement and thermal expansion instead of splitting. Its flexible nature preserves watertight integrity through temperature cycles and road vibrations.

• Elastomeric formulation maintains flexibility in hot and cold conditions
• Adheres to common RV roof substrates when used with proper primer
• Creates continuous, seamless coverage to prevent water intrusion

Will this reduce interior heat on sunny days?

Yes—the coating’s bright white, heat-reflective finish lowers solar heat absorption on the roof surface, helping reduce interior temperatures and easing the load on air conditioning systems. Reflective properties also slow material degradation from UV exposure.

• White, high-albedo surface reflects sunlight to reduce heat gain
• Protects roof materials from UV-related wear and fading
• Can contribute to lower cooling energy needs in hot climates

Which surfaces and roof features can I use it on?

The product is formulated for use on EPDM, TPO, fiberglass, and aluminum RV roofs and is suitable for skylights, vent covers, and awning components when prepared correctly. For EPDM and TPO, using Liquid Rubber EPDM Primer is recommended to ensure optimal adhesion.

• Compatible with rubber, thermoplastic, metal, and fiberglass roofs
• Works with vents, seams, skylights, and accessory flashings
• Use primer and seam tape where movement or transitions exist

How much coverage will one gallon provide and how do I apply it?

One gallon covers approximately 50 square feet when applied to reach the recommended final thickness; a single 1–5 gallon pail is sized to coat a typical 30-foot RV roof when used with the full repair system. Apply by brush, roller, or airless sprayer in temperatures between 50°F and 90°F for best results.

• Estimate: 1 gallon per 50 sq ft for final recommended thickness
• Apply with brush, roller, or sprayer; follow primer and surface prep steps
• Seal joints with lap sealant and seam tape for a watertight system

Who is this for: This product is made for RV owners, DIY enthusiasts, and professional technicians who need a durable, weather-resistant roof coating that can be applied at home over a weekend. It’s suited for owners of travel trailers, campers, pop-up campers, and motorhomes who want a low-VOC, reflective solution to stop leaks, extend roof life, and improve comfort without specialized tools.
