Our take on the Liquid Rubber RV Roof Sealant – Camper & Trailer Coating

Liquid Rubber RV Roof Sealant is a water-based liquid rubber coating you brush or roll onto camper and trailer roofs to seal leaks and stop water intrusion. It bonds to EPDM, TPO, aluminum and fiberglass, cures in about 24 hours over RV lap sealant, and stays flexible across temperature swings. The brilliant white finish reflects sun and helps keep the interior cooler. It suits owners doing their own roof maintenance who want a seamless membrane instead of patching tape or panels. Against one-part silicone and solvent-based coatings, it is lower-odor and easier to recoat, but EPDM and TPO need a primer first for the best bond.

Pros
  • Rolls on like paint with a brush or roller
  • Water-based and low-odor compared with solvent coatings
  • Stays flexible in heat and cold
  • Seals seams, vents and lap sealant in one membrane
  • White finish reflects sun and lowers roof heat
Cons
  • EPDM and TPO need a primer for full adhesion
  • Needs surface prep and dry weather between 50°F and 90°F
  • Full cure takes about 24 hours, so plan around rain
  • Several coats are needed to reach full thickness

Questions and answers

Does it work on EPDM and TPO roofs?
Yes, but Liquid Rubber recommends a primer on EPDM and TPO for the best bond. Clean the roof first and let it dry fully.
How many coats do I need?
Plan on at least two coats, with more on seams and low spots. A 5-gallon pail is sized to cover a 30-foot RV at the recommended thickness.
Can I apply it over existing lap sealant?
Yes. It cures over RV lap sealant in about 24 hours and forms a continuous membrane over seams and vents.
What temperature can I apply it in?
Apply between 50°F and 90°F. Below that the coating may not flow or cure properly.
How long does the coating last?
Liquid Rubber rates the service life at about 10 years. Actual life depends on prep, coat thickness and sun exposure.
Can I paint over it?
The coating itself is the finish, and it comes in brilliant white. Painting over it is not required.
