My husband painted 2 coats on our diningroom ceiling with a good quality ceiling paint and good quality roller (we know not to go cheap on these items) but the ceiling came out blotchy. This ceiling was painted several years ago----this wasn't the first time on this drywall. What would have caused this? Someone suggested we apply a coat of primer and paint it again. Any suggestions?
Yup. Best first step would have been a coat of primer / barrier type paint to help even out differences in moisture content and absorption. Unfortunately, sometimes this does not become obvious until after you have already painted.
You'll basically need to start over with at primer, then finish paint.
Was this actually "ceiling paint".?
Ceiling paint is flatter then flat and hides more imperfections with less shadow casting.
If you roll it one way, add a little more paint, then roll across, it turns out good.
