HENG'S INDUSTRIES - 471284 Elastometric Roof Coating - 1 Gallon

This product spreads like a thick paint. It dries quickly-within an hour or so at 80 degrees. That may not be "ready to use" but another coat could be rolled on at that point. (we used two coats as the entire black membrane had been exposed on our camper) It has been rained on several times since the installation.and seems to be fine. The coverage was good. As I mentioned, we needed two thin coats which was around 1 and a half gallons for a 29 foot travel trailer. This product is much cheaper than liquid roof and some other brands. If it lasts more than a couple of seasons, it will be worth doing again. This was an EASY application.

Seems to work. We got several days of rain after the application, and the leaks seem to be fixed.

This is absolute crap. Don't use it on your RV. first off all water based products can only repell water for so long then they leak. This stufftakes several days to dry. 4 days after I had applied this it rained and my roof leaked. I should have purchased liquid rubber instead.

'this is a great product and we apply it every year. Our RV is a 1996 and the roof looks brand new...no more chalking or leaking!
