does enternabond expire?

Have a roll of eternabond tape that is about 3 years old, is that safe to use or is it to old or does it ever expire?

As the others have said, it will still be good. I store mine in a zip lock bag to keep dust/dirt and stuff off of it.

I will also add, if you have concerns about it sticking, use the Eterna Prime. Either the spray can or the liquid brush on. That primer makes the stick like it is on steroids!! Eternabond is very sticky to start with, but when you use the primer too on a properly clean surface, the primer makes an amazing difference. Just make real sure you place it in the right spot as it is not moving once touched.

I myself now use the primer all the time. It adds super high confidence it will stay bonded, everywhere even over non uniform surfaces. You can use lacquer thinner to clean off any excess primer after the bond is done.

Hope this helps

9 yrs still fine.
Used it last year to seal the entire snowmobile trailer roof and its held fine this season. Caulk around its edges when you use it. It prevents it from lifting if it should decide to do so.

Oh, man. My expensive roll of Eternabond that I have used about 6" of is turning 5 this year. :S

Now would be a good time to reinforce your seams or any patches. :)

I had a partial roll I kept in a cool basement for 6 or 7 years. It worked fine.
I think if you keep it in the RV year round from 10 to 100 degrees is when it goes bad.

Hi,

I improperly stored my 4 inch eternabond for 7 years. It still worked just fine. YMMV.

It will be fine.
