Rust-Oleum 710 Elastomeric Roof Coating
Brand: Rust-Oleum. Features include a 10 Year Warranty and a waterproof seal within 6 hours. The coating uses Cool Roof Technology with about 80% reflectivity, helping reduce energy costs by limiting heat absorption. It’s designed for EPDM and other common roof substrates and provides a durable, flexible membrane that resists cracking as temperatures shift. Suitable for flat roofs on RVs, tiny houses, or commercial buildings that require reliable weatherproofing and energy efficiency.
Dicor RP-CRC-1 EPDM Rubber Roof Acrylic Coating Part 2
Brand: Dicor. This coating is well suited for retrofit installations and provides a protective barrier to extend EPDM rubber membrane life on RV roofs. It offers a universal fit and a white color for a stylish roof appearance. Compatible with EPDM and PVC, it pairs well with Dicor Rubber Roof Cleaner/Activator for better adhesion, making it a practical choice for RV owners upgrading roof protection.
Liquid Rubber RV Roof Sealant (5 Gallon)
Brand: Liquid Rubber. This 5-gallon, flexible waterproof membrane creates a durable seal across EPDM, TPO, fiberglass, and aluminum surfaces. It features heat-reflective properties to reduce interior temperatures and extend roof life. The coating is designed to work as part of a complete roof sealing system, often pairing with the Liquid Rubber EPDM Primer to boost adhesion on EPDM and TPO surfaces.
Liquid Rubber RV Roof Sealant (1 Gallon)
Brand: Liquid Rubber. This 1-gallon version provides a flexible waterproof membrane with heat reflective performance. It supports multiple roof substrates, including EPDM and TPO, and pairs with compatible primers to improve adhesion. It is suitable for travel trailers, campers, and RVs, delivering durable, leak-proof coverage across seasonal temperature changes.
100% Silicone Roof Coating
Brand: Countryman Coatings. This silicone roof coating claims high reflectivity and broad adhesion across surfaces like metal, EPDM, PVC/TPO, and more. It emphasizes energy savings and reduced cooling costs due to reflectivity, alongside the benefit of strong adhesion without primer in many scenarios. It’s positioned as a versatile, long-lasting option for flat and low-slope roofs on homes and RVs alike.
HENG’S Industries Rubber Roof Coating
Brand: HENG’S INDUSTRIES. This EPDM-focused coating is designed for RV roofs, addressing seams and tears. It accepts expansion and contraction with temperature changes, offers UV resistance, and claims non-polluting, non-toxic properties—making it a practical option for owners seeking an easy-to-apply, flexible roof repair product for seasonal RV use.
Buying Guide: Key Purchase Considerations
When choosing an EPDM roof coating, consider substrate compatibility, reflectivity, and ease of application. If energy savings are a priority, look for high solar reflectance and white or light-colored finishes. For RVs and trailers, flexibility and adhesion on EPDM, TPO, and metal surfaces are critical, as are memory and elasticity to withstand temperature shifts. A long warranty signals durability and manufacturer confidence.
Application method matters: some coatings are spray-applied, others can be brushed or rolled. For larger roofs, a 5-gallon container reduces refills, while primer compatibility can improve adhesion on EPDM surfaces. Compatibility with Dicor or Liquid Rubber accessories may simplify installation. If you plan to retrofit, ensure the product is suitable for retrofit installations and does not require extensive surface preparation beyond cleaning.
Durability versus cost is another balance. Premium silicone or elastomeric coatings typically offer longer lifespans and higher reflectivity, potentially reducing energy costs over time. However, these may come with higher upfront costs. For light-duty RV applications, a reliable 1- to 5-gallon option with a strong warranty can provide solid protection without complexity.
Finally, always follow manufacturer guidelines for surface preparation, curing times, and temperature ranges. Proper surface cleaning, priming where recommended, and adequate curing will maximize coating performance and longevity.
