Just curious, what situation would occur that you would want to coat over your EPDM membrane? I've had the membrane delaminate from the sub base and was able to glue it back down. I have sealed any joints and openings using Dicor color matched sealant. Any tears I used EPDM repair tape. What is the advantage of coating the whole thing? Is it just a stop gap measure for roof replacement?
On a side note you would definitely want to be sure the membrane has not delaminated before you put this stuff on.
