some customer said: After two years in the South Carolina sun the roof still looks and works great. There’s a couple of spots that will need touch up, the largest maybe 1 1/2″ by 1″ but the majority of the coating is intact. It’s not bright pretty white any more but has weathered to a dirty white color. I certainly would use this again! See original review below.

I used Heng’s rubber roof coating to coat my 28 ft trailer roof. The original roof was getting old and was chalky, thin, and checkered from age. The South Carolina sun was not helping and before I replaced the roof I decided to try to reseal it. I used 4 inch Eternabond tape around the vents, antenna, and skylight over the shower. I washed the roof with a TSP solution and rinsed it. In hindsight I should have probably washed it again but I will explain that later.

I cleaned the edges of the roof with denatured alcohol and a rag, then applied the Heng’s coating to the edges with a brush. I did the roof with a roller by pouring a puddle on the roof and rolling it out. I worked from front to back then left it to dry overnight. You could still see the color of the old surface through the Heng’s much like the old wall color when you paint with latex paint.

The next day I went up on the roof and when I walked on it I saw that small areas were peeled off. I tried to rub the edges of one and the Heng’s peeled up like it was not adhering to the old surface. It was about the size of a dinner plate when I got done. The rest seemed to be sticking so I attributed the peeling in that spot to my prep and hoped that it was the only area. I did the edges and rolled the roof again and let it dry overnight. The 28 ft camper took 1 1/2 gallons to complete.

The next afternoon I looked at it and it looked good except for some small bubbles, maybe a half dozen, 3/4″ in diameter. Again I thought it might be the prep and left the roof alone. That was in the first week of July.

The Heng’s rubber roof coating said 24 hours cure time, but this application had a month in the SC sun before we used the camper. This weekend was the first time we used the camper since then. We had a downpour, “build an ark” rainstorm driving to our campsite, and two nights of severe thunderstorms when we were there.

I didn’t know what to expect since there were the adhesion problems with the application. When we left I went up on the roof to sweep off the top of the slide-out and saw the Heng’s coating survived the trip and the storms there unscathed. No bubbles, no peeling, no damage. I went up on the roof tonight and looked closer and could see no evidence that it had bubbled or peeled.

Apparently after curing it is much more durable that it looked initially. Time will tell but at this point it seems to work as advertised. The only thing I would do differently is wash and rinse the roof twice and maybe use denatured alcohol on a rag and wipe it down the entire roof before applying.
