Epoxy over faired surface before painting?

Post by BlueRidgeBoater » Mon Nov 10, 2014 9:05 pm

I put 4 coats of epoxy on after fiberglassing my hull, then sanded it down good. I then applied some resin putty to small holes or other imperfections in the surface. After I sand that, do I need to do another coat of epoxy over the areas I used the putty on, or can I prime and then paint? I really don't want to have to do another coat of epoxy and then have to sand the whole surface again before priming and painting if I can avoid it. Thanks.

if you mean by "resin putty" epoxy with powdered filler added, you are all set.
GlenL recommends:
Before doing any finish work or applying finishes, allow the last coat of epoxy to cure 5 to 7 days at 70 degees F, longer at colder temperatures. Wipe down the hull with a water/ammonia dampened rag or sponge. This will eliminate the greasy feeling amine blush to make final finish sanding easier and minimize clogging of the abrasive.

Yeah, I mixed some microspheres with resin and skimmed it over some small holes. So, should I wait 5-7 days from when I did the fairing? If so, that will work out okay because I want to paint this weekend.
