I just painted a primed steel garage door with acrylic paint. I let the first coat dry for the recommended 4 hours, applied another coat and let it dry 18 hours before activating the door. At the top of the door some paint peeled when I lifted the door. How do I fix that?
You don`t mention which paint peeled.the top coat you applied,or the primer and all.I`m thinking your top coat came off.In my opinion, always wait a day for anycoat to sit before applying another.Latex will stay sticky for long periods of time.If it peeled near a joint in the sections,Keep that joint seperated,lightly feather the edges with sandpaper and repaint.Keep door sections open as long as possible afterwards.
