If you're going to do any part of the painting or prep work on your own, you must know that the first step in preparing a surface is washing it. Since dirt can affect the smoothness of a surface area -- and therefore paint's adhesion to it -- use soap to remove any dirt or stains. Make sure there's no soap left on the walls when you're finished; also make sure to remove any gloss with sandpaper and vacuum up the leftover dust.
I'm hiring an interior painter and that is why I was reading this comment list. I'm concerned about your comment about Angie's List. Some of us don't have personal recommendations for tradespersons, and rely on sites like this. Are you saying that Angie's List's reviews are not complete or that they do not print some of the negative reviews? It's hard to know what to do - I have not been able to find a person who just had their paint done so I can ask him/her about the quality of the painter.
Painting your home, both inside and out, improves its curb appeal, character and resale value. Painting is one of the quickest and easiest ways to give your home a face-lift -- and it yields some of the most dramatic results as well. If you have ever visited the painting section of your local hardware store, you know how overwhelming the multitude of paint choices can be. In addition to colors, there are finishes, stains, maintenance and other options to consider. And, if you're interested in adding a mural or trompe l'oeil, you're looking at a whole different set of choices and associated costs.
