EternaBond RoofSeal White 4" x50' MicroSealant UV Stable RV Roof Seal Repair Tape | 35 mil Total Thickness - EB-RW040-50R - One-Step Durable, Waterproof and Airtight Sealant

The roof of my enclosed trailer started leaking. The 12 year old factory sealant used under the trim had finally given up.After removing all the trim I found how poorly the trailer was constructed. They used rivets every 8-9 inches or so which left a lot of the aluminum skin buckled up; and would have been difficult, if not impossible, to seal. I added a couple hundred additional rivets to make everything smooth, then cleaned all the areas that were going to receive the Eternabond tape. Application is straight forward and easy. Be warned, you need to plan ahead, have a helper if you need one, you only get one shot at placing the tape. After you get it down give it a good rolling. It also worked great on the top-to-side 90° transition; just place it on one surface, roll it to adhere it, then fold it over and roll some more.Pro's: Ease of use, durability, adhesion, quality. This will forever be my goto solution for trailer roof leak repairs.Con's: None really. There is a learning curve to using it but if you've got two brain cells to clank together to make a spark you'll be able to figure it out.

Had a minor leak on my RV roof and could see it was were there was slight cracking of the sealant around the air conditioner. I used this roofing tape and the leak is gone. Just be aware this stuff is so good that once you put it down it will not come up so make sure it is where you want it because once it is put down you are not going to pull it up and move it but that is what makes this tape so good and solves the leak because it does have such a strong sealant. It is very solid and thick tape and looks great once applied.

I found this tape is an excellent solution to repair holes or tears in the rubber membrane roof covering of our travel trailer. I have tried other caulking materials with only fair results. When we got a bad tear after driving the trailer under a low-hanging branch at the campground, I repaired the tear with this tape. Is was so impressed with it that I ordered more to replace the caulking seal on the ends of the roof where it meets the aluminum siding. I'd twice had leaks in this area. After re-sealing with this tape, all is nice and dry.This tape is about the most sticky stuff I've ever worked with, but the adhesion is not fully activated until pressure is applied. This makes it a little easily to work with than the world's most sticky material. You peel the clear film off the gray side of the tape to expose the adhesive putty. When applying, know first that any air bubbles that get trapped under the tape cannot be pushed out - that's how strong the adhesion.Before application, I scrubbed the area with acetone on a rag.When applying to anything but a tiny area, I found that it works very well to have another person align the long piece of tape while I would slowly peel away the clear film and simultaneously applied pressure in a way to assure all of the air is forced out from under the tape. When applied, the go over the tape with any kind of pressure. The pressure can be hand pressure, or a roller, but a small roller is very handy for large seams. If you repair area is larger than 3 inches wide, just overlap successive strips of tape with 1 inch of overlap. This tape sticks well to Dicor lap sealant caulk, but you can get a smoother result by removing most of the old caulking material. I removed a thick layer of old caulk with by careful application of a wire brush spinning in a 4-inch hand grinder. The wire brush didn't seem to damage the rubber membrane when used with care.This tape will not stick to silicone, so any seams or joints previously repaired with silicone caulk need to be cleaned carefully of the old silicone.I think this tape would be great for seams in many devices or constructions that you wanted to make water-proof.

This tape is strong & sticks extremely well. This is a very good tape for camper seams.

WORKS GOOD

Great for sealing up the cracks in my camper. You get a ton of material which is worth the money. Perfect thickness so it easily fits under plastic trim. Cuts easily with scissors and it matches my white paint close enough so it doesn't stick out like a sore thumb.

This tape is amazing. Super sticky and seals really nicely. It was thick and used for sealing out camper roof.

Awesome stuff! Available in different sizes. Great value. Just the right thickness. Easy to apply.Looks good and works great.
