Removing self levelling Dicor

Use a propane torch to warm (to hot to touch) up a putty knife.

Use a putty knife and lots of patience.. beware of using Eternabond tape on a roof fixture you may want to replace some day such as sewer and air vents. Dicor in these cases is much easier to remove and replace. The tape is fine for roof seams, or permanent sealing of endcaps, etc..

Well, I don't know whether it was a Dicor around the bottom of my antenna mount, but probably so. I removed the antenna mount to install solar panel, and cleaned the area with Methanol (aka Methyl Hydrate). Alcohol stove fuel. Painters use it for cleaning metal and other surfaces. Sells here in Home Depot and Canadian Tire store, in the US - don't know. I wrote about this - it dissolved my Dicor or whatever that sealant was. Gives out a nasty smell while dissolving, so try not to breathe in much.

Mainly, it is the endcaps that I want to seal. Good to know about the other areas needing access for repairs sometimes.

I'm on my 2nd fifth wheel, and have replaced more roof vents and such that have rotted away than I care to think of.. I can't imagine the nightmare it would be to try to peel away eternabond..

Of course living in Arizona the sun here cooks these things very hard..

I used a hair dryer and putty knife on one end cap -- then I got smart and put Eternabond over the dicor - isn't picture perfect/pretty but it's water tight.

EB tape WILL stick to Dicor just in case you can't get it all off. You don't need to remove 100% of the Dicor, just the globs and make sure the surface is smooth and level. For Dicor removal, I use a cheap HF heat gun on low setting (use caution) and plastic putty knives. Lowes sells an assortment of red plastic putty knives for about 3 bucks. I rounded the corners on the putty knives as I found them quite sharp, even for plastic.

Dicor is quite easy to remove once it's heated up.

Most important thing when installing EB is to make sure the surface is cleaned with the solvent EB recommends and all areas are clean with no loose Dicor.

Removing Dicor

I need to remove the self leveling Dicor from my RV roof so I can put on Eternabond. What is the best way to remove the Dicor?

What material is your roof made of?

First scrape off all of the big globs with a plastic scraper, being careful not to damage the roof surface. Then put on a pair of gloves and use a rag dampened with mineral spirits (make certain that your workspace is well ventilated)... this will easily removed excess Dicor.

Despite all of the naysayers, petroleum distillates (mineral spirits) can be used safely, even on TPO, as long as you don't allow it to pool & soak on the roof. Note that Dicor has petroleum distillates in it which evaporate out during the curing process.

I have a fiberglass roof on my Winny. Thanks for all of the good information.
