How long can epoxy primer sit before top coat?
epoxy can sit just about forever but if it sets more than a couple days you should sand it and spray a coat of reduced epoxy as a sealer. most epoxies these days have around a 7 day recoat window but the more you wait the worse the adhesion is. i always like to get something on it within 24-48 hours.
When can I paint over epoxy primer?
The time between primer and paint is going to depend on which epoxy primer you use, the temperature of the shop and how liberally the primer is applied. I usually wait until the primer is dry to the touch and won't show a finger print when touched lightly.
