TPO Roof Question

A quick question about re-sealing the vents on my M.H.'s roof. I have a 2006 Fleetwood Flair with what I believe is a TPO roof (that is what the manual says). I was able to look at the back side of the rubber roof where it was tucked into a vent, and the back of the roofing material was light gray in color). The roof itself is in great shape, but the chalking around the vents is pretty cracked. No leaks yet, just want to get a fresh seal before something does leak.

I plan on using Dicor Ultra Sealant self leveling lap sealant. Do I also need to use the Dicor primer first? Or is there a better way to do it?

Also, about how many tubes do you think the project will take? The M.H. is 33 feet long (2 vents, plus plumbing vents, Fridge, end caps)

Dean... I think you will be able to buy two tubes and have some left over. I use the Dicor Lap Seal on all my RV projects...Self flowing or the non flowing...both are great....clean with Iso alcohol before applying let alcohol evap and go.

To clarify, do you use the primer before applying the sealant? Or does the alcohol do the job of the primer?

Thanks for your help.

Here is a little blurb from the Horses Mouth that might be of assistance.

I just had these same questions, here is my thread. I ended up using a heat gun too loosen up the caulking, then scraped it off. Cleaned it off with some water, then mineral spirits, then let it dry. Here is the link to the thread. Possible caulk repair?
