I have a 1992 Fleetwood Bounder, 28'. My late husband had coated the roof with Kool Seal Elastomeric in 2003 and now it has blistered, like little volcanoes. I am trying to take it off but some is still sticking really good. Rubber roof underneath appears to be in good shape, it is tan with a mesh fiber below the rubber. How can I tell if it is EPDM or TPO in order to repair three very tiny spots? Best way to clean roof off, dish soap,laundry detergent, protectall cleaner for rubber roofs, etc.
Thanks, in advance, for any help.
Both TPO and EPDM roof materials are handled the same way. I believe Fleetwood used EPDM. I doubt you will be able to remove the Kool Seal.
Some use Spick & Span along with many other detergents, I prefer Murphts Oil Soap. Do not use anything containing citric acid.
Either Dicor self leveling caulk or Eternabond tape should repair the small spots, just clean the area to be repaired thoroughly with acetone or alcohol before applying.

If you see "fiber mesh", it's must be EPDM. TPO is like a hard plastic. EPDM will pull and grab like rubber when you drag your fingernail across it. DICOR caulk is safe to use on either - silicone NEVER on EPDM!
I would try to cover any "mesh" areas with more Kool Seal - you probably can't turn back. I believe they make a primer - that might explain your problem.
