RV Flex Repair Self Leveling Caulking Lap Sealant | White | 4-10 oz Tubes of RV Caulk and 1 Roll of 4 inch x 50 foot RV Flex Repair Seam Tape (White)| for Rubber Roof | EPDM | RV Leveling | Bond Kit

I just finished coating the roof on my 25 foot travel trailer so I can't discuss the durability of the material. It went on about as expected and it took me about sixteen hours over three days. I cleaned it three times with degreaser and scrub brushes. I did a final wipe down with acetone. There was 145 sq ft of roof surface area to cover and about 100 lineal feet of cut-in. I got the 3.5 gallon bucket and had a lot left over. I might have done it with two gallons. It dried to the touch in about four hours and I waited overnight to re-coat. I applied it at 65 to 80 degrees and 25% to 40% RH. I could only use the cut-in brushes once since they hardened in a few hours. I reused the roller by storing it in a one gallon freezer bag.The only complaint I have is the material needs to be strained even as delivered. There are a number of small pieces of solid material embedded in the coating. I strained the second coat and did not have that problem. It is likely only cosmetic.Also, if this stuff gets on something not to be coated wipe it off quick.

This stuff is the bomb!! Unfortunately my rv roof started to leak in many different areas over a period of 12 years, so I prepped the roof, applied the product and went through a rainstorm in the fall. No leaks, this winter in Utah record rain and especially snow. We had a bad wind storm that blew off my tarp I keep on the trailer to protect it, then rain and snow came, I panicked cause we had a freak afternoon snowstorm that lots of snow fell while I was at work with no protection from the tarp. Then as quick as that storm came out came the sun and melted all the snow dripping off my trailer. I went inside to check for water damage expecting to find at least some due to how bad the leaks had become. Alas to my joy there was no leaks whatsoever! I was so happy and prayed for thanks to the makers of this product, time will tell, but so far have been very happy!!

We have a 2021 Grand Design camper that came with a "Lifetime Warranty" from the dealer....only issue is, we have to take it back to them every year to certify it for the continued warranty....costing travel money, plus a currently $85 charge. This year, they said we needed the roof resealed (which they NEVER mentioned the need for), and they wanted to charge $1100 for!! So...deciding to do it myself, I found this on Amazon with high ratings, so I tried it. Cost for one gallon seemed excessive, but much less than the dealer...as long as I did't fall off the roof (I'm not as young as I was). After checking the weather, one day using the "official" roof cleaner sold at the dealership, letting it dry for a couple days...then wiping down the seals with acetone to prep them (the product suggests since the camper is fairly new) I brushed the product on. It went on with the consistency of somewhat thick paint, and it dries rather quickly on the brush, so it needs to be done with haste. I did NOT do the entire roof...just the seals...I can see where this could be used for the roof, but you would need a lot more than one gallon. So far, it seems to be doing what itshould...and IT has a lifetime warranty...hopefully, I won't have to do this again anytime soon, but the roof needs to be cleaned of course..it sits outside, and not under any cover, so it does get blackened. I had to take pictures to send back to the dealership for the warranty...and I'm wondering what they will come up with next time for revenue. Also...side note...they would not warrant the tire monitor, which stopped working...said they've never had that happen before..I was the first (RIGHT!) They also do not offer the lifetime warranty any more....

I power washed top of camper first, waited 24 hours and placed 1st coat. Applied another coat 24 hrs later, when dried looked so nice. Had rain a couple days later. Everything was great!

Product goss in easy. Did arojnd all openings first with Brust. Next das startet with roller. The Material is thicker then Paint. Listening to some utuber, poure firectly from the pail onto the roof. It is difficukt to junge how much is on the roof and with the roller one had to really press down hard to spread the material. I did not do that and having a curved roof, gravity took over eventually and the thick mess gravitated towards the sides. Looked like ocean waves. Fortunately did I check on the progress and was able to spread out a bit more. But the coverage is now - in part - a messy uneven surface rather then the smooth result it should be. It's all sealed up, though, but my sense of pride is severely damaged.Had to buy a gallon more and will now, carefully, cut in from the roofline to the raingutters on left and right side. And then that's it for that adventure.I like the material and it seals - I'm convinced of that.Just don't do too much of the product at once. Better do a 2nd layer if you feel like more is better.

I had read numerous reviews on various products and went with the Ziollo. People rave about it and honestly I will rave as well. I had also read that some purchasers bought the 5 gallon pail only to have half of it left over, so I just bought 2 gallons to do my 30' travel trailer covering the spotted EDPM original roof. I prepped by wiping the surface with wet towels and then again with acetone to set up adhesion. Yes, if you "paint" this stuff on, you'll use less than the recommended amount and cover the old roof. However, it looks even better when you apply a thicker coat. I know now (because I used more on one area near the end of my 2 gallons) that when you spread it on and simply move it around with the roller instead of painting it on, it self levels and gives you a glossy, level finish. Now that I've worked with it and became familiar with it, I'll finish the job by buying 2 more gallons. So, lesson learned, purchase the amount they recommend and you WILL use it if done right. While it costs more to buy the individual gallons, stirring is a snap. The stuff is easy to work with and easy to clean up drips if they haven't set. I am waiting for it to cure to post before and after pictures. Going into this camping season knowing I've probably got the best stuff out there protecting the roof.

Great product, easy too use.

Excellent price but making a neat bead of caulking was difficult.
