Ziollo RV Roof Lap Sealant - Self-Leveling EPDM Caulk for Rubber Roofs, Seams & Vents - Waterproof Sealant for Motorhomes, Trailers & Campers - White, 4-10 oz Tubes

Nothing better! I’ve try a few other brands nothing smooths out and stick as well as this stuff!!

Works very well comes out like marshmallow fluff, self levels very nicely. We were hit with a downpour 30 minutes afterward, and it didn’t change the appearance at all.

We had no problems at all with the order. It arrived on time. I used it to re-seal the caulking on our 14-year-old trailer. It's a Lap Sealant so it filled in every crevasse and cured perfectly! I bought it a second time to put away for the next project.

This product seems to work just fine. The only thing that was disappointing is that it has a two year self life, and the tube I received expires in five months. This means that I have to discard a pretty full tube.

Awesome product. Highly recommend. Applying this is like marshmallow on your snowball.

easy to use on our rv rubber roof

Used this to seal the roof of our camper. We have had no issues since application including after a heavyrain storm.

This is the rare product that FAR exceeded my expectations. Once the rubber roof was clean, I followed the directions to install two coats, each on successive days, and finished with a thick, durable and non-slippery roof. Some reviews mentioned that the cured Ziollo was slick but that is not my experience. You have to roll it on thick. I actually used a throwaway paint brush as my poly nap roller was being pulled apart by the Ziollo rubber. This worked like a champ and I hope it’s as durable as it seems to be.

It’s runny when it comes out. It’s that way for the self leveling properties. I should have tarped over the area I was doing because I have many pine trees in my yard so needles and pine seeds got onto it. A barn or big building would be nice so I could drive trailer into it. This stuff is great!! I will always keep some on hand.

First time using this product to reseal my tent trailer vents. I applied it over existing sealants after thoroughly cleaning them with mineral spirits. It went on very easily, the texture was easy to work with and it self-levels perfectly. I even let my teenager complete one of the vents on his own. Highly recommend this brand. We used up almost one full tube per vent. See pics.

Works well.

Very easy to use and unlike many others was not dried up on the end but flowed well. Very pleased with the results so far. Hopefully it can withstand our harsh Canadian weather.

This product did a great job on the RV roof. Self levels well, it is very liquid and designed for the top of flat surfaces, would not recommend for walls as it will just run off. It says it dries fast but mine was still very tacky after 24 hours. After two days it was cured very well and looks like it is there to stay. Great product for roof top applications,
