Sealing my TC's EPDM Roof

I tried searching for a thread using every combination of words I could think of with no real luck.

I want to seal my EPDM roof with the best product based on people's experiences. I keep my 2007 TC's roof clean and it is in good shape for it's age but I feel it's time to put a protective coat on it.

I've spent hours on YouTube reviewing clips spouting the merits of all of the usual suspects (Dicor 2-part system, Flex Seal, Henry Silicone RV roof sealant, others etc.) More confused now than ever.

Any recommendations based on first hand experience/ or can you direct me to a thread where this has been already thoroughly covered. Thanks.

This is just my experience, we have a 21 year old 5th W. with the original EPDM and no coatings added. I keep it under a roof when not in use and wash it and put a rubber roof conditioner on it every other year. It is in very good shape for it's age.

Our 2005 TC had the Dicor coating on it when I bought it in 2012. It has held up very well.

After, I am guessing about 50K miles, it had a few scratches in the coating, not the EPDM, so I recoated it last year.

I have replaced the EPDM on 2 of our previous campers and I think that one would have been an excellent candidate for the coating rather than replacing the rubber. I had no experience with it at the time.

I will use the coating in the future as long as there is no damage to the decking.

You do need to clean it well and use the Dicor cleaner/activator so that is sticks well. 1 gallon was enough to put 1 coat on our TC. If it were the first coat I would have put 2.

The most time consuming part about using the Dicor was putting plastic over the sides to keep the cleaner/activator off. I don't know if it will actually damage the fiberglass but I didn't want to take the chance. It was in the spring but was too hot and the tape kept coming loose. I think it took me about 6 hours as I had to keep climbing up and down from the roof and I had no helper.

Good luck.

Likely reason why you can't find the answer is because the question has never been asked.

I believe the whole point of the EPDM roof is, that you don't have to be constantly re-coating it with "sealants." It's meant to be relatively maintenance free.

The big problem with putting any coating on is, there's no way to get it off. Only way to fix it is to peel the EPDM up and replace with new.

I've seen rumors that Flex Seal does not last, degrades quickly in the sun.

Thanks for the link but not really the answer to the questiohn I'm asking. Let me try it a different way.

I have a 15 year old roof that is in good shape. Once clenaup up(annually), it looks very good. I see no "black" spots bleeding through.

I'd like to seal the roof with a good product designed to help protect it and hopefully, extend it's life.

What are the better products out there, for this purpose, that people have used with success.
