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.
