Eternabond Failure

In applying anything to a surface os something else, it is all about proper prepping of the surface for proper adhesion.

But perhaps people prefer to believe marketers lies, combined with price and internet rumor, outweigh logic, and uncommon sense.

I applied it around the around the skylight over the shower and it created a dam and water leaked inside...I wont do that again.

Prepping the surface won't have any effect on the cover cracking and splitting. Same thing happened to sections on my solar cables in just over one year!! Believe it or not, 1+ year!!! The tape was still stuck to the roof just fine, but the outer surface was sun rotted and cracked, and peeling off. Leaving the adhesive base still there! Probably wouldn't leak as such, but that expensive **** should last longer if you want to believe the name!!!

Package was "Eternabond", but who knows if not a chinese counterfeit??!!

I can see adding sealant along the sides of tape if you are really anally retentive, but you shouldn't have to cover the tape to make it last.

mine has been on the roof seams for 5yrs
no problems so far, knock on my wooden head

I applied Eternabond to my front and rear cap seams about 8 years ago.
It still looks good and is holding up very well.
Maybe it was just a bad batch of E/bond?

That is precisely why I would never purchase a "used" RV which had had Eternabond tape applied. Hidden defects? In the past, too many people touted Eternabond tape as "once and done". Well as we hear, that is far from being true.

I personally would only use Eternabond tape as a patch to repair a accidental tear in the roof, should that ever become necessary.

To each their own. I'll stick with cleaning, inspecting, and Dicor self levelling calk.

It's Eternabond, not Eternaseal. The sun rotted stuff is still stuck in place.

Did you have leaks on the seams when you applied the tape, or used it only as precaution?
Main problem with the tape is that dual layer is hiding imperfections and wrinkles holding the water.
You are not aware about the problem till the water shows inside, or roof collapse.
5 months ago I applied latest technology roofing coating on my house flat roof. I had dealt with black and silver coating in the past and results were mixed.
I keep eye on new stuff and it looks really good. The roof had small leaks last rain season, so I am waiting for next real test this winter, but I think I know what I will use on my camper rubber roof this winter.
Main advantage beside lifetime warranty - with nice white coating you will see each hole or crack.

It was a precaution
I clean and resealed the molding strips, tighten loose screws
And put on the eternabond

The comment about hiding imperfections, is just talk
If the stuff is stuck to the roof, then no water is coming in thru the eternabond,
If it come in from some where else, that is not Eb fault

The same thing could happen with Dicor

I think it's important to overlap the roof edge on the sides of the Caps when sealing with anything to keep wind blew water from being forced in

After 10 years I found that the factory tape on the cap seams had failed and needed to be replaced. Not going to complain, just part of maintenance.
