Eternabond over uncured Dicor lap sealant

I believe you will discover a sticky mess that is not adhered to anything.

I would remove the Eternabond and the Dicor (as much as possible), clean the area well and apply New Eternabond.

I definitely would not trust it the way you have it applied.

I would guess the Dicor will set at the edges of the eternabond tape, and a small distance under it (1/4 to 1/2 inch I would guess). I assume the eternabond tape would prevent it from curing just like the container it is shipped in. Given enough time (weeks / months) in warm temps it is likely to cure through. Just remember, the eternabond tape isn't attached to anything, just goo at this point. If you can't clean it all off and start over, another top coat of Dicor will at least seal it, if not make the mess larger later.

Just leave it. EB is difficult to remove.

The Dicor sealants are urethane based. They cure in the presence of water/humidity. Let the Dicor cure and then roll the tape again to release the micro-adhesives in the tape.

If the tape doesn't stick, remove it with a heat gun/hair dryer, scrape the Dicor off with a plastic spreader and caulk remover, clean the whole area with acetone, and apply the tape again correctly.

The reason God made beer was to slow down projects like this so a guy doesn't get carried away. Next time, more beer.

If you really want to slow down, weed.

True, but it adds complexity and lack of completion. :B

My experience was that it cures in presence of air. (Which contains humidity of course).

With poor air access it will cure poorly. One thing I hate in Dicor is that it takes weeks to cure completely - this is with proper air access.

If you don't have to have the tape over Dicor, - then don't. Scrap it off now, Dicor with tape, and reapply Dicor alone.

But you'll think you did a good job!

Thanks for all the advice. I should mention the tape is in pure contact with the roof membrane on one edge, the metal siding on the other, each with about 1/2" contact along the edge. If it was just stuck to uncured eternabond I would have removed it.
I'm thinking about making a natural oven by laying black across the edge. Black what though, I have some plastic tarp, some floor mats, maybe I'll lay both across the seam tomorrow and see if temperature increase will speed up drying.
So I'm the first to make this mistake it appears. I've done a search and no one else asked this.
The problem with removing it is I have done such a good job on the side where eternabond ends and the sides are curing. It's parked indoors until tomorrow morning.
Any ideas on the oven idea to really get some heat to it. Here in Idaho its 60 day, 30 nights for next couple weeks .
Some sealants cure funny, they need air at first to evaporate some chemicals and that's when they skin over and the remaining stuff has no access to air and they still cure. I was really hoping Dicor was this way and someone had actually done this. But no one thinks more harm than good so far, so I'll leave it for now and razor cut the ends if I'm forced to remove it. Thanks.
