WHAT WALL PREPARATION IS NECESSARY? A smooth, clean, dry, mildew-free wall does count. If your wall isnt in good condition, the prettiest paint color wont compensate. Before you even think about starting to paint, scrape or sand away rough spots. If necessary, strip old wallpaper. Depending on the paper and how it was applied, you may find a spray-on liquid combined with scoring to be less cumbersome than renting a steamer. If you do rent a steamer, follow the directions carefully to avoid accidents. If any glossy surfaces remain, dull them with sandpaper or liquid sandpaper. Scrub walls with mild detergent and water. Rinse with a sponge and clear water. For mold and mildew, wash with a solution of 1 quart household bleach and 3 quarts of water. For the smoothest finish, always prime and treat spots with a special primer that prevents bleed-through. Dont ever paint over damp or wet walls. If the weather dampens the walls inside or out, run an air-conditioner or dehumidifier or wait for a dry day. HOW DO THE PROS PAINT WALLS?
