I thought my TPO was waterproof and not susceptible to water seepage as long as it's not been cut etc. So, why the need for a general roof coating on it?
I know the Dicor sealant is compatible and effective on the roof seams which must be protected against water seepage. A periodic inspection can show if the Dicor on the seams is cracking, at which point a new coating can be applied to seal the cracks.
My 2006 trailer with TPO is still waterproof. I check it periodically visually on the outside and with a moisture meter on the inside. I've used no roof coating except the Dicor on the seams when needed.
