Sealer goop on roofs

I tackled this today. The goop was in worse shape than I thought, and there was a ton of it, so I decided to try to remove it. What a pain in the neck. I got 90% of it off, cleaned it all up with mineral spirits and applied the eternabond. I’ll be keeping an eye on it for a while.

As long as you applied it correctly, I'm sure you're good to go! You've probably avoided future issues.

I did enternabond over the Dicor.
Cleaned the Dicor first and then applied.
Eternabond is great stuff.

It's very critical to not get any wrinkles in the Eternabond when you apply it. We applied it around our shower skylight due to leaks over the years. It worked, for awhile. Finally had a tech look at it. A wrinkle trapped water over time and then it slowly released. He had a heck of a time removing the Eternabond and replacing the skylight unit to fix it correctly. No problems since.

I would seal the cracks wait about a month to make sure it cures and then eternabond over the seam.

People have had good success either way, putting the Eternabond over the Dicor, or removing the Dicor. I removed it on my last trailer.

I'm planning on doing it on my current trailer and I think I'm going to go over the Dicor. I don't have any cracking yet.

As said above, good prep is critical. Eternabond has great instructional pages and videos.

I shaved off the high spots of the dicor, then applied eternabond over the whole seam after cleaning with acetone. Been about 6 years now. Very pleased.

Don't discount Reenee's comments about PREPPING the surface well. Makes all the difference in a lasting repair.

Thanks. I already have a roll of Eternabond and I’m sure it will hold up better than the goop.

Yes, you do need to remove the old, gently and either reapply or use Eternabond. We did that. You can purchase a cleaner by Eternabond or use mineral spirits sparingly - sparingly. Wash off then apply the Eternabond.
