Ask the Expert Question-and-Answer Archive by Ron Joseph October, 2005 Applying Epoxy to Aluminum for Exterior Applications Q. Do you know of the best way to prime aluminum for an epoxy coating, in a field application as I described previously? A. At the very least, I would want to abrade the surface to remove the naturally
formed aluminum oxide. Ideally, you would abrasive blast the surface and then
immediately apply the wash primer. But you need to be careful that you do not
apply excessive primer, else you might get blistering or delamination of the
epoxy. Ron Joseph
