Maintenance for Silicone Roof Coating on EDPM
So back in 2008 I replaced my EDPM roof with fresh EDPM and Eterabonded the heck out of it to try and do a "once and for all" kind of job. I documented it on this forum but older posts seem to have ...

I put on Tropicool a year ago, including over some Eternabond on an EDPM membrane and got good results, There was one leak still, however, which I traced to the edge of one of the Eternabond strips, where evidently two coats of Tropicool did not manage to seal. It seems the Tropicool coating was repelled by something about the Eternabond edge, and left an uncoated seam. I used a silicone caulk I bought at Lowes to caulk over that edge, and it seems to have bonded well and stopped the leak. I have no clue why that one spot failed to coat, and no others have proven a problem, but you might want to watch out for a similar issue.
The trailer lives most of the time in storage under some black walnut trees, and thus it is impossible to keep black stains completely at bay. But a soft brush and Simple Green does seem to work cleaning the Tropicool layer.
