How to remove decor self leveling sealant from roof

[Bob_Vaughn]

How do I remove Dicor self leveling sealant from roof without damaging the rubber roof. I replaced the crank up antenna with a Jack antenna so there was some sealant from that antenna the the Jack antenna replaced that and it got knocked off by a wayward limb. Then the replacement antenna got knocked off by a branch so there is 3 layers of sealant. Once I get the Dicor off the rubber what is a safe way to remove the residue plus around the crank hole the rubber is coming loose from the roof what should I use to re glue the rubber?

I bought a set of the red plastic putty knives from Lowes and rounded the sharp corners off so they did not gouge the roof. Hot day works great, or heat the dicor up with a heat gun. Hard to get off when it's cold.

Use a metal putty knife that you can hold and when you push down at an angle, the blade will bend flat against the membrane, and move flat blade part just above the membrane (hope that makes sense).
You may leave an old thin layer of old sealant.
Try to get enough old stuff started so that you can grab and pull up as the blade is cutting thru underneath.
If the membrane is stretching as you are cutting, come in at the different angle or direction to prevent the membrane from stretching.
Use the acetone sparingly, to clean.

Dicor web says to clean the area with Dicor roof cleaner/rinse and then clean that area denatured alcohol. Be carefull what you put on a rubber membrane.
Check out their website for how too videos.

Everyone keeps saying this, but from my experience mineral spirits leaves an oily residue. This could prevent Dicor from adhereing well.

Acetone

Personally I scrap off as much as I can, then clean with something like Awsome cleaner, get it good and dry. Place a generous bead of Dicor down, fasten the item down, followed with lots more Dicor over screw heads etc. Never had a leak in 10 years.

Plastic scraper should do the trick. Remove as much as you can, replace the item and reseal with lots more Dicor.
