Liquid Rubber RV Roof Sealant — White 1 Qt elastomeric, waterproof, solar-reflective RV coating

Liquid Rubber RV Roof Sealant is a water-based, elastomeric white coating that creates a flexible, solar-reflective waterproof membrane for camper and trailer roofs.

If you need a durable way to protect an RV, travel trailer, pop-up or motorhome from leaks and heat build-up, this 1-quart professional-grade coating was formulated for exterior roof repair and maintenance. The product rolls on like paint, bonds to common RV substrates when used with the recommended primer, and remains flexible across seasons so seams and roof penetrations can move without cracking the seal. It’s zero-VOC and designed so homeowners and DIYers can complete a roof refresh with basic tools in a single weekend.

How does this sealant stop leaks and handle temperature changes?

The coating forms an elastomeric membrane that bridges hairline cracks and seals around fasteners, vents and seams. Because the film stretches and recovers, it tolerates thermal expansion and contraction common on metal, fiberglass and rubber roofs without splitting.

• Flexible waterproof membrane resists tear and movement.
• Elastomeric formulation maintains adhesion across temperature swings.
• Compatible with typical RV materials when used with EPDM/TPO primer.

Will this product reduce heat inside my camper?

Yes — the white, heat-reflective finish lowers solar heat absorption on the roof, which can reduce daytime interior temperatures and lessen cooling demand. The reflective surface helps divert sunlight rather than converting it to heat that penetrates the interior.

• Bright white, solar-reflective coating deflects sunlight.
• Helps reduce roof surface temperatures on sunny days.
• Contributes to lower interior heat gain when applied to the whole roof.

Which roof materials and areas can I use it on?

This coating is formulated to work on a wide range of RV roof substrates including EPDM, TPO, fiberglass and aluminum when the correct prep and primer are used. It can also be applied to vent covers, skylights, seams and awning components as part of a comprehensive waterproofing system.

• Use with Liquid Rubber EPDM & TPO Primer for rubber and single-ply roofs.
• Suitable for metal and fiberglass after proper surface cleaning.
• Pairs with lap sealant and seam tape for joints and transitions.

How much coverage and what is the typical application process?

The product spreads like paint and the guideline is roughly 1 gallon per 50 sq ft to reach the recommended thickness; the 1-quart size is for spot repairs, patches and small areas. Application is straightforward: clean with the RV Smart Cleaner, prime EPDM/TPO surfaces, then roll, brush or spray between 50–90°F (10–32.2°C).

• Follow a three-step system: cleaner, primer (if required), then coating.
• Apply with brush, roller or low-pressure sprayer for even coverage.
• Store sealed containers above freezing for touch-ups later.

Who is this for? This Liquid Rubber RV Roof Sealant is aimed at RV owners, DIY repairers and small maintenance contractors who want a long-lasting, flexible waterproof coating that’s low in VOCs and easy to apply. It’s ideal for anyone repairing localized leaks, recoating an aging roof, or upgrading to a more reflective surface to improve comfort and extend roof life. Use it as part of the complete Liquid Rubber system — cleaner, primer, coating, and seam products — for best durability and ten-year protection when applied according to the manufacturer’s guidelines.
