We now have about 10 coats of paint on these interior, textured walls because there are streaks when the light shines. How do we get rid of these sheen differences in the paint? We’ve tried priming it again and re-painting, but we still have spots of different sheens.

We are building a house and want to know if there is any ‘waiting period’ before painting the interior walls? At what stage do you paint the primer and how long after that can you paint the walls?
