dicor self leveling lap sealant on slide out roof?

First, I would find out why the tape is bubbling.
I don't know what the result would be of the seals rubbing on the dicor.

A picture of the bubbling tape, and exactly where you plan to put the Dicor, would get better response. One thing to keep in mind, it takes quite a while for Dicor to FULLY cure. If you close the slide, and Dicor makes contact with slide seal, or whatever, it may pull loose, or damage seal, next time you put slide out.

I would remove the old tape and put down some new Eternabond. Be sure to clean the surface before applying the new tape.

That's what i would try to do. When you install the new tape, then i would put some Dicor around all the edges. If you do it that way and do a good job in the cleaning/prepping, i think you will be good for a long time.
Good advice as suggested, give the Dicor some breathing time to cure .

I went to a maintenance seminar put on by the manufacturer of my unit and they did not have a very high opinion of Eternabond and would not suggest it be used anywhere. They suggested it could be used as an emergency patch but that the edges often failed to seal and should have a bead of Dicor applied to seal them.

I have never used it myself, just relaying what the pros said.

Then I would say those pros DON'T KNOW JACK. No manufacturer or business that does RV maintenance is going to recommend ETERNABOND since it cuts into their profits for redoing caulking or having a trailer fall apart so they can sell a new one ... THOSE ARE THE REAL FACTS, IMO. FACT IS while the edge of Eternabond tape might lift it's not a common occurance if you apply it properly and it can be almost entirely eliminated with a tiny bit of sealant along the edges and if an edge does lift the only problem is generally cosmetic and doesn't really effect the rest of the tape that is still adhered to the surface.

I'm curious. Did those pros have anything to say about the use of silicone caulk?

To the OP, I would still find out the cause first.

Sure hasn't been my experience. I have Eternabond tapes sealing everything on the roof and it has never leaked or pulled an edge. About the only way an edge can loosen is if there was improper surface prep or the tape wasn't rolled down hard. The adhesive in the Eternabond tapes is in the matrix of the tape.

These were guys who build them. They had no motive to suggest any product over another since they do not offer their services for hire and do not sell caulking or repair materials of any kind.

Think what you will but if the guys who build them for a living will not use a product perhaps there is a good reason.

My new Coachmen uses a strip of Eternabond on the top of the slide out, right where the OP is talking about. Strangely enough, it wasn't stuck down very tightly, and would probably not have stayed put had I not took a roller to it.

Might be why the OP's tape was bubbled...
