Eternabond Failure

[TurnThePage]

I have to eat a little crow. A while back someone posted that Eternabond could trap water behind it, thus causing rot or some other issue. I cockily responded with, How could water get behind it? Well I found probably half a cup of water trapped behind Eternabond tape wrapped around my fridge vent. As I kept searching, I found that a good amount of the tape had dried out and literally rotted away. In the attached photo, you can see where I used left over tape to secure solar cable to the roof. Look how it cracked open. If you look close, you can see tiny cracks all over it. Yeah, it's a mess too. :B

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.

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.

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.

Well, doggone it! With a name like Eternabond, I thought it might last longer than the trailer itself! What's in a name...

Everyone that I have talked to says you must properly prep. After applying anything periodically check it for cracks or damage. If you see cracks you can put self leveling dicor on top of cracks. If it looks bad remove and replace. I inspect a couple of times a year.

I think I removed about 30 feet of eternabond from my Fleetwood that PO slapped here and there.
The dryrot behind it was huge.
Even when aluminium beam under the slide broke the weld - PO slapped eternabond on crack.
IMHO that stuff, just like silicone caulk should not be sold to aging men.

12 years? Well, nothing lasts forever.

I have had my eternabond on the front cap seal start doing the same thing. Fortunately I caught it a few weeks ago but also had a bit of water damage. Mine has been up there about 8 or 9 years. Mine is in the same place over the dicor caulking. I think that may be the issue too. Other places look fine.

Hard to tell depth in the close-up picture. Was the EB stretched to get down in that valley that was holding water?

Well one more reason to do a yearley inspection and re seal of your roof.

It's probably been up thete 12 years. Why would roof prep or, lack of, cause the tape to dry out and crack?

[newman_fulltime]

way the roof looks it wasnt properly prepped

How long was the Eternabond on the roof?
Did you apply it, (or can you blame it on someone else?) 🙂
