Dicor Clean & Prep

Does it remove the residue left after you scrape the Dicor self leveling sealer off the roof?

Hi Dennis; Not sure about the product you are asking about. All I have ever done is if I need to remove some Dicor and replace I have used mineral sprits to clean all the Dicor off down to the fiberglass and let it dry. Then just a small about of dish soap and water and let dry. Never had any place I reapplied Dicor lift off the surface using what I posted. Hope someone else here has used the Dicor Clean & Prep to give you a better answer.

Dennis, I've never used that product. I always use Acetone. I don't think you would ever remove all the old caulk. Just get as much as you can and clean it really good before applying new caulk or tape!

Looking at the MSDS sheet it seems to be a product that just makes oily residue water soluble. Based on that I would say it will not remove old Dicor residue. Use the mineral spirits first then apply the prep IMO.

I just cleaned and repainted my fiberglass roof with dicor cleaner and paint. Where caulk was cracked or loose on the edges I scraped it until it was secure. On some types of seams you will do more damage trying to remove it all off. I washed it 2 times like it says and 2 coats of paint at right angles like directions. I used the dicor self leveling caulk on the seams as well. It turned out really well but only time and weather will tell how good the job will hold up. I also took the white flex seal paint and painted the top of my black A/C covers to cool them down some. Good Luck

I forgot to recommend that you place the Motorhome so that it slopes to one side for the runoff to make cleaning easier. After each wash get a leaf blower and blow off around all penetrations and the seams so it will dry better.
