    • Two years later and it's still intact and in good shape
Size: 1 Gallon
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 this product 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 product 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. ... show more

    • seems like a good product

from an application perspective, as easy as rolling paint. It's been Fall and Winter and not leaks so it seems to work, but we used two coats

    • Love this stuff
Size: 1 Gallon
Easy to paint or roll on, it looks fantastic and sticks to everything, making it very useful on an rv roof with obstacles to paint around. Used it 2 years ago, with no leaks, and freshened roof up again with another coat recently. Also used it under slide out for extra sealing, and used small paint brush to redo my raised white letter tires on my truck. Bright white and easy to work with, creamy not watery, easy to give a quick stir prior to usage. Worth keeping an extra quart around for other projects like shower grout etc. ... show more

If you're going to do two coats you definitely have to thin it out with water

    • Easy to work with, easy to clean up, and strong like bull.
Size: 1 Gallon
I tore two holes in my camper roof, through the rubber sheet and digging in to the plywood. One was about 8 ft long and the other about 6 ft. I also had holes along the rounded edge of the roof. Yeah, bad news. Also, I did this on the very first trip with a brand new camper. I thought about dousing it in gasoline and lighting it on fire and claiming the insurance money and going back to tent camping, but instead, I did a lot of research and settled on trying EternaBond WB-4-50 WebSeal - 4" x 50' and Heng's Rubber to fix it instead. Spoiler Alert: This was a very good decision. The edges of the torn roofing were stretched and "frilly" so I cut the rubber off around the tear until it would lie flat, leaving 1-to-2-inch-wide-by-6-to-8-ft long gaping holes in the rubber. Following the manufacturer's instructions, I cleaned the rubber around the holes using Borax, a little water, and a scrub brush--it turned sterling white again! Then I cleaned up the plywood shreds for a good sticky seal. I cut 2-to-3-ft lengths of the WebSeal and followed the instructions for applying it using a Speedball Deluxe 4-Inch Hard Rubber Brayer. Boy oh boy does that stuff stick. Finally, since this the repair tape has a somewhat absorbent outer layer (not all of it does), I used a smooth paint roller with Heng's 461284 Rubber Roof Coating, and over three days put down three coats of rubber roof coating over the patches. We've had some crazy rain storms, and I've driven many highway miles since I did this. I've had no leaks and it looks the same as the day I finished the job. I used around 1/4 to 1/3 of the can to do 3 coats over roughly 30 sq ft, and will keep the rest handy to add another coat every year at the beginning of camping season. Heng's is easy to work with, easy to clean up with soapy water, and strong. This product probably saved me over $1000, which is what the RV place here in town wanted to patch the roof. ... show more

    • Easy application and seems to be of quality
Size: 1 Gallon
I used this today on my Trailer roof, followed the directions at first with a thin coat, it was easy enough to apply with a paint roller that has a long broom handle attached. Hand held paint roller not so much. I stupidly left the used but closed can on my bathroom fan cover, it slid off around 8pm, spilled and so I had to quickly spread it over the entire roof again. Which I was planning on doing tomorrow but.. ooops. My fault. Hopefully it dries fine overnight and cures tomorrow well in the hot sunny day. ... show more
