Liquid Rubber EPDM and TPO Primer – High-Performance Basecoat for RV, Camper and Trailer Roof Protection, 1 Quart

Very strong glue that I used to stick down my edpm rubber sheeting on my garage roof.Very strong fumes from it even when used outside.Best to wear a mask.

Seems to work well. You’re going to throw away your brushes. It’s very very sticky so plan correctly so you don’t have to step on it. It stays sticky and then you put the rubber coat on it.

works great i use nothing but this brand for rv roofs

Had to buy primer to ensure adhesion. Primer was great making a sticky surface. Coated around all vents. Cleaned and sanded the areas. Instructions said not to prime lap sealant. However i primes all areas to be sealed. Looks great and my newer roof will no longer have holes in the sealant. Priming adds an extra step.

I’m just finishing resealing my hunting travel trailer roof and used this system. The primer is easy to go on with a roller or a brush. Just make sure the roof has been cleaned prior to use. I have a concrete washer head for my pressure washer and it cleaned the roof great. I had to do a small amount brush trim work around pipes, vents, AC, drip edge…I applied the majority the primer with a roller. Start at one and work yourself towards your exit. Let that dry a day or so and it should be good to apply your new rubber roof top coats made by the same company. I will without question confirm this primer will make your roof sticky. I initially was working with my sandals on until I actually got stuck to the roof several times. I had to get down and work the roof with an extended roller standing on top of a latter. There you have it.

Very easy to apply,lot better than doing a room
