Liquid Rubber Roof Coating

Q: What is the best type of coating for an RV roof?

It depends on your roof substrate: Polyurethane — best durability and abrasion resistance, good for roofs with foot traffic Liquid rubber — best for rubber and metal roofs; highly compatible and flexible Silicone — excellent UV and ponding water resistance but harder to recoat later Acrylic — good budget-friendly option; easy to apply

FAQs

Can I use liquid rubber coating on my RV roof?

Yes — liquid rubber is one of the most popular choices for RV roofs, especially EPDM membranes. It’s highly compatible, extremely flexible, easy to apply, and provides excellent waterproofing.

What is the best type of coating for an RV roof?

It depends on your roof substrate:

Polyurethane — best durability and abrasion resistance, good for roofs with foot traffic
Liquid rubber — best for rubber and metal roofs; highly compatible and flexible
Silicone — excellent UV and ponding water resistance but harder to recoat later
Acrylic — good budget-friendly option; easy to apply

Do I need a primer before applying the coating?

It depends on the product and substrate. Road Guard XD TravelPRO and Liquid Rubber do not require a primer. However, fiberglass and some metal roofs may benefit from a primer coat for better adhesion. Always check to make sure you know what you are coating.

Will the coating protect against ponding water?

Yes — liquid rubber and silicone coatings in particular are excellent for areas where water pools. RV roofs are typically flat or have very low slope, so ponding water resistance is an important feature to look for.

Can I walk on my RV roof after coating?

Yes, once fully cured, both liquid rubber and polyurethane coatings can handle light foot traffic for maintenance purposes. Polyurethane coatings offer the best foot traffic resistance. Avoid dragging equipment or sharp objects across the surface. Silicone is the slickest when wet.

Can I apply RV roof coating in cold weather?

Most roof coatings require a minimum application temperature of 40°F and should not be applied if temperatures will drop below freezing within 24 hours of application. Solvent-based formulas generally have better cold-weather application tolerance. Both Road Guard roof coatings (Liquid Rubber Roof Coating and XD TravelPRO Roof Coating) are solvent based.
