Summary: I've repainted a bedroom; and after non-meticulous 2nd coat on the ceiling, the ceiling appears to have streaky roller marks. Disclaimer: I am an painting novice, be gentle. Details: I repainted a drywall room that was orig done w/ sprayed on builders paint in an antique white. I patched and sanded all imperfections (mostly thumb tack holes), sanded/washed, primed w/ a latex primer, finished w/ latex Kilz "one coat coverage" flat white interior paint. Painting steps: cut in, rolled ceiling, then walls Problem: After completing the walls, I noticed the paint was a bit thin in one area of ceiling, so I chose to put a 2nd layer on the whole ceiling to ensure evenness. About a 3 hr gap elapsed betw 1st and 2nd coats. It's worth noting before applying the 2nd coat, ceiling was otherwise streak free (besides the thin area). I applied 2nd ceiling coat perhaps not as carefully as I should have, w/out perfectly ensuring even coverage and meticulously smoothing out edges. I suppose I (stupidly) thought that since I had done an even 1st coat, I didn't need to do a "perfect" 2nd coat, and it would dry just fine. I was obviously wrong. After the 2nd coat ceiling coat, i can see a lot of the moves/streaks I made w/ the roller. The walls, however, look just fine. Solution: What do I do from here to fix the ceiling? The ceiling doesn't have raised paint edges from the edge of the roller - rather, it looks like differences in sheen/roller marks - tough to describe. Should I do a 3rd coat ceiling, ensuring smooth coverage? I used a 3/8inch roller - should I try a 1/2" roller to do a 3rd coat? Should I lightly sand the ceiling before doing this coat, or not necessary? I'd prefer not to sand as I really don't want to kick dust up on the walls again - but if it's necessary so be it. If I should sand, should I "scuff" sand with a pole (I saw this in other threads)? If a 3rd coat is needed, any tips of doing this coat, guidelines, etc? Should I prime over the paint 1st, then do a 3rd coat? Thanks for any tips. This is my first attempt at repainting and I'm hoping I didn't screw everything up.

I am using the Raulph Lauren River Rock paint to paint my family room. I used 2 coats of KILZ on the walls for a primer coat (Probablly overkill). I have put 3 coats of the RL River Rock paint on with the "special roller" and I still have LINES??? What am I doing wrong??????
