Make sure you prep, and I mean PREP the roof before applying. Started with detergent scrub and that is a chore with no shade on a 30x8 roof 12 feet off the ground. Make sure your brush is medium, not stiff, and scrub-scrub-scrub. Then rinse. rinse, rinse...did one section at a time, worked area just big enough to reach across. Let dry over night. Make sure all your patch work is done before washing.... After patching the 'holes' around skylights and vents, washed the entire roof with detergent, dry, then wash with acetone. Using a 3inch brush, did area surrounding the vents/skylights edges and patches. Application was simple: Pour about a pint on the roof...roll. When it quits pushing in front of low knapp roller, pour some more, and roll. Was able to leave a really thick coat of material even and uniform on the surface. After initial application, had enough left over material to pour more around the skylights and further fill the edges of repair material. Finished application at about 1100am. At 1042am the following morning it rained...2.25 inches. Not a spec of water inside the RV. Success. Read full review

This stuff is the best sealer available. I fixed an 18 yr. old RV that I ran through a wicked hail storm. No leaks, it’s awesome! Before starting to seal wash thoroughly with a good detergent like Dawn. Rinse well and patch tears and holes, seams, and cracks with RV Roof sealer tape. Then put on as many coats as you think it needs ....( the more the better). Allow 3-5 hrs cure time between coats depending on temperature/humidity. Update; After a year of brutal Texas weather this coating is still looking like new. UV resistance is great and it’s staying pliant. No leaks or checking from shrinkage. I’m very satisfied with this product. Update—-; I had softball/grapefruit size hail that beat all the windows out of my house, and the RV. Busted the windshields out of my vehicles also. 8 days later baseball size hail again broke the windshields that were replaced. The HENG’S roof on that RV is 100% ok. It withstood three ferocious hail storms. I am not exaggerating, the RV is history/totaled/shredded, but that roof doesn’t appear damaged. There was some rain and that roof does not leak. Don’t hesitate to take preventive measures and give your RV roof a good thick coat before it needs it and save damage from leaks. Read full review

This is an initial review, time will tell. The product seems to be of very good quality and has a thickness to it... Pre-cleaning of the roof area is a must and following the instructions is a must. I used dawn liquid but made sure it was washed off completely, had no problem with this. The product went on simple and easy on my old EPDM roof/after minor repairs were made. I would give the product an excellent rating, but check back with me in a couple of years.

i read the reviews on this product and took a chance. The price was more than i hoped but i ordered 4 gallons to do a 1994 10x30' motor home. I read that coverage was about 2 1/2 gallons for this size. after a weekend of GOOD prep i was ready for the coating. WOW this was a great coverage product . used about 5quarts (a little over a gallon) for the first coat . Im a journeyman painter and put on alot of products but this covered great. I brushed the cut work and rolled the flat and put a good heavy coat down and im very pleased with the results. if the product holds up IM SOLD . a bit of advise..... use on a cooler day as it will skin over in the bucket and roller tray. low humidity was about 70 and overcast but no rain . I will put a second coat on and see how it holds up. 2 thumbs upRead full review
