My contractor painted a waterborne acrylic enamel over my oil based enamel trim. Without sanding it. What is going to happen? The trim needs a 2nd coat but I’m afraid I might need to sand it first. I want it to be right because I am getting ready to have wood floors laid. I am right in the middle of painting the whole house.
Waterborne acrylic enamel was painted over oil based enamel.
