Identifying rubber roof type

:C I definitely learned something on this post.

thanx

A representative told me to use the Ultra Sealant for our TPO roof. I confiremd the roof type by contacting the manufacurer of my motorhome. They also said I would need to use the ultra sealant primer.

Incorrect. I've owned trailers with EPDM rubber roof sheeting and others with TPO ... EPDM is easy to identify because it's smooth and often doesn't lay perfectly flat across the full length / width of the roof, TPO which is a stiffer, vinyl type of material has a grainy pattern that can easily be felt and does lay perfectly flat. EPDM chalks naturally over time, TPO doesn't chalk at all. As noted by Dicor one wants to use caution when sealing a TPO roof as Dicor self leveling lap sealant can be safely used with some formulations of TPO but not with others. For those other formulations Dicor has developed a different two part system called Ultra Sealant that should be used on this type of TPO - use Dicor lap sealant intended for EPDM rubber roofs and the TPO sealant / roof material may bloat or disfigure. :E

For what it's worth...I have had rigs with both EPDM and TPO. My TPO had more of a fabric feel and texture than the EPDM. The later is more "rubbery."

check the dicor (IIRC) web site showing how to determine which you have. involves pulling off the inside molding around a vent opening.

Either way, use Dicor.
