The Eternabond Blues......

[Onesweetvan]

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?

Clean CLEAN Clean CLEAN any surface. Then clean some more.

X2. 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!

x2, You need to use a roller so the adhesive oozes out. If you did that and it still came up, I don't know the answer.

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

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