I have a situation, new semi-gloss latex paint is peeling by the sheets off of newly primed walls. The thing is, I used a flat ceiling paint as a primer which I have done many times before, and a standard latex semi-gloss over it and it is peeling off in sheets! Help
How long did the paint dry before peeling and how did it first happen? Your right that there shouldn't be any problems. I have used a flat first coat many times without problems.
First stop peeling the paint, I assume you are picking at it. It does take time for a semi-gloss to cure and get fully adhered to the surface. Maybe your paint needs more time to cure. What brand are you using?
