The coating is bright white. I used a roller to apply to the roof. The finish was reasonably smooth, but not slippery sleek. It is durable. In fact, I just cleaned my rooftop with a floorbrush and a bleach/soap/water mix. It washed clean, and the coating did not lift after a year of being applied. This coating does exfoliate like the rubber roof material, so the RV stayed cleaner and very minimal dirty black streaks from normal dirt. I rolled the coating, let it dry and went back to reseal a few places with the butyl caulk. I am happy with the result. **Q: does hengs roof coat work well on rubber roof previously coated** A: Yes, this product will work well on a previously coated rubber roof. Make sure all dirt/oils/grease is removed from the roof prior to application - recommend a hose and a cleaning/degreasing agent - I used Dawn dish liquid and a brush but others like Tide powder - both should give you acceptable cleaning results. Heng's has GREAT adhesion to all types of surfaces so you shouldn't have a problem. **Q: Is this as good as Dicor?** A: This stuff is great. I've never used Dicor, I have a 30' toy hauler. 3 gallons gave me 3 coats with a good amount left over. Start with a clean roof. ## Frequently Bought Together - HENG'S Industries Rubber Roof Coating - 1 Gallon | EPDM | Durable Coat | RV, Motorhome, Camper Roof Repair | Waterproof & UV Resistant | 42128-4 - Dicor 501LSW-1 Self-Leveling Lap Sealant, 4 Pack - RV Roof Tape White, 4 Inch X 50 Feet RV Repair Sealant Tape, Stop Camper Roof Leaks, UV-Resistant, Weatherproof and Reliable for Camper, Trailer, Boat (4In-50FT) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/271147845-industries-rubber-roof-coating-1-gallon-epdm-rubber-roof-rubber](https://www.desertcart.us/products/271147845-industries-rubber-roof-coating-1-gallon-epdm-rubber-roof-rubber) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-23*
