Liquid RubberEPDM and TPO Primer – High-Performance Basecoat for RV, Camper and Trailer Roof Protection, 1 Gallon

Awesome product! Rolled it on with a small roller dried fast! Became very tacky so the rubber sealer could adhere! Great product 10 outta 10 recommend

Applied on clean dry surface. Worked well.

Very sticky, even after 48h. You cannot walk on it so do half of the roof so you could make the second coat of the finish product and the finish coat will dry then you’ll be able to walk on it and do the other side.

This product works great. If people would go on line and read the directions they would not have to walk on it. It's not made to walk on. I had a 10 ft step ladder so I could roll the 1st coat of Finnish on. I could then walk around without sticking to roof ! This primer is not made to walk on...

I had first used a cheaper primer and elastomeric roof coating and that just peeled right back off with no effort. So I started researching what works with rubber coated rv roofs and this was recommended. And it certainly works. This stuff is so sticky it's hard to not get yourself stuck to the roof when you go to put the rv coating on. It may not be cheap, but you can either take a chance on something cheap or else try this.

We purchased our first RV it's a 1999 Tioga. The roof was completely black. It had never been done. I followed the instructions and both the primer and top coat worked exactly as described. Yes, the primer will be tacky, yes, if you touch it, step on it or disturb it. It's very sticky. That's its job. We did 3 coats of primer and 3 coats of top. We are a 29' class C and still had almost a full gallon of each left. We used rollers just plain cheep ones. We did use brushes along the edge. We were in Colorado with low humidity and mid 50 nights and mid 80 days. It took a total of 4 days. I'm sure you could do it faster but this worked for us. Make sure to wait until it's at least 50 to start. Other than that. This was a fantastic product. We has had no issues with leaks. Those that left bad reviews obviously just can't follow directions. If you can you will 💯 be happy.

I used their cleaner per directions before applying. As soon it was dry, I rolled the first coat of liquid rubber.A couple days later, I was going to apply another coat and they was five small bubbles that didn't stick.I don't know why, but it seems you can just peel it off. It's just possible that it needed more cleaning.Time will tell.

We had a leak in our fish pond and this product with the finishing product solved the problem. No more leaks. Easy to put on and their help line is great.
