Roller marks when painting?

my room is in the middle of being painted purple. Its good paint but it needed a third coat but on some of the walls you can see were the roller went and where we outlined the trim why is that and how can i fix my walls? help please!Roller marks when painting?
some deep tones are a bear...i'v had some colours take three and then a fourth coat to adequately cover.


if it has been previously painted applying primer is pissing in the wind, so don't bother with that.


you need to keep a ';wet edge'; which means that one person must cut in and one person must roll and you both must stay on top of it or you will get a banding effect that you are talking about, also roll as close to the ceiling and base and adjoining walls as you possibly can without touching them...hope this helps i know it is alot of work and a royal pain in the butt, but you can make it work.Roller marks when painting?
Did you put a primer on the walls before you started painting? Sometimes even if its good paint it leaves the marks. I just painted the inside of my entire house and found that it took three coats for each room. Don't worry about it. I know its exhausting but if you want it to look great then put the third coat on.
Sounds like two things occurred - first you were going too thin or dry on the final coat. Second you may not have waited long enough before applying coats for the first ones to thoroughly dry. Also, third coats with gloss or semi-gloss are always iffy.
You should always use a primer before you paint. You only need one coat to paint. But since you've already started to cover the roller marks you have to paint in straight, uniform strokes.
You press to hard on the roller and use to little paint on the roller. Don't be stingy with paint. Let the roller do the work and don't press on it. Don't just go up and down but spread the paint a little on the wall in kind of a v pattern. Soak up the roller in the pan every couple of rolls. Been doing that for many years.
