I've used Eternabond Tape while patching/ repairing my 20 year old rubber roof and have, initially, been quite impressed with the product. I mostly used it to cover the joint between the aluminum siding and roof membrane after lifting off the rubber to repair some roof sheathing rott. I used acetone to clean all surfaces prior to using the tape. The last time I worked on the roof was last summer and in the fall, parked in my driveway with much rain, the repairs seemed to hold up well. However on a recent trip the leading edge in both front and rear joints lifted up near the center and caused leaks. No tape residue was left, it came off as though I had never applied it. Has anyone else had this tape lift off like I describe? What is the cure to prevent this in the future? Looks like I'll probably redo the whole roof this summer, but I had planned on using Eternabond on the front and rear seams, now I'm not do sure about that. Any thoughts?Moved to Tech Issues forum from DIY.

EB did not cure my leaking skylight, but Heng's roof coating did. I'd opt for that instead of the tape.

It helps to caulk the edges. Don't know if that would have solved your problem but it could not hurt.

Some of the tape I installed with an acetone prep lifted up. I used Laquer thinner the next time. No problem.

Caulk the edges and make sure to use a roller with a lot of pressure to activate the sticky tape. The first time I tried it I didn't use a roller, just rubbed it down, and it didn't stick very well. Had to redo it (PITA!) The second time I strong armed it with a roller and caulked the corners. It is not coming off, ever!

If you did that and it still came up, I don't know the answer.

Like was said before- Clean area with lacquer thinner first.

Eternabond had an issue with a defective batch of 2" tape a while back. I had the same problem where the tape just lifted off. Call EB and describe the problem and they will send you replacement tape. Be sure to use the EB cleaner before applying the tape to be sure you get a good seal.

There were some bad batches of Eternabond a few years ago. The company appears to have stood behind their product and replaced those flawed products as they've sprung up. Dunno if yours qualifies. I've had Eternabond on my RV roof, which is permanently outdoors, for about 9 years now. It's stayed in place very nicely. Aside from some unique bends and corners, I have never considered caulking the edges of the tape. It's supposed to replace that need!

You have to roll it hard enough to see the grey adhesive starting to ooze out the edges.
