What problems have you experienced with the paints? For me, I use Behr, BM, SW and others with good results. But, I always spend more time on prep than paint.

First wash the walls with dawn, it has good grease cutting capabilities. I use a roller style sponge head to wring out as much solution as possible. Rinse using fresh water. Make sure the mop head is new as well.

Touch up any holes with a good spackle, I like drydex. sand smooth and spot prime.

Prime the walls. Yeah, I know they all say paint and primer in one. I don't care. Most walls haven't been painted in a wall, why waste paint on your first coat adding moisture to the wall?

Buy the best roller cover you can for the finish you want. Before using it, wrap it with painters tape and then remove the tape. Notice all the loose fibers? They won't be on your walls now.

Now, you are almost ready to paint.

Run the roller cover under water to get it wet. Wring it out well. I roll it out on one of the walls. The reason for doing priming the roller, is that it will accept paint faster.

Make sure your paint is thoroughly stirred. Strain it as you pour it into your pan/tray. And your cut pot. Never dip a brush into the paint can, you will introduce contaminants.

Now, you are ready to paint.

Hope this helps, let me know your thoughts.
