I need some expert help. I just had my basement finished. They put knockdown texture on the ceiling. I put a coat of drywall primer on the ceiling and then painted it with three coats of Sherwin-Williams Brilliance ceiling paint. That left streaks everywhere. I thought maybe the problem was thin ceiling paint so I followed with two coats of extra white flat SW Superpaint. The streaks are still there. I’ve tried different rollers (1/2 and 3/4) and different techniques (push hard, roll lightly, go only in one direction, go in both directions, longways, sideways, paint the “M”) but can’t get rid of the streaks. The only things I can think of at this point are maybe that I need to prime the ceiling again, or just have it sprayed. I would love to know what an expert thinks. Thank you!
