Dicor Removal Question

You talking about Dicor lap sealant or some other product?

I have a 2003 trailer and have never removed any of the lap sealant. I clean it with a rag and a little turpentine, wipe it dry with a clean rag an put the new sealant right on top of the old. It will stick to the old sealant. If you have to remove it due to replacing a pipe vent or vent, I would try a hair dyer to help make it plyable and slowly peel it off. Use a plastic putty knife..

Look it up on YouTube. I do not have a rubber roof, but I just did it using a metal scraper and hair dryer - then acetone. And, yes - you can put it over the old stuff if you clean it up real good - that's on YouTube also.

Good luck!

As said unless you are replacing what its covering, just clean and recoat.

I use a putty knofe which I rounded the corners on to prevent the edge digging in. It does snot have to be perfectly removed.
