WHAT WALL PREPARATION IS NECESSARY? A smooth, clean, dry, mildew-free wall does count. If your wall isnâ€™t in good condition, the prettiest paint color wonâ€™t 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. Donâ€™t 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?

They are easy to apply, and brushes and rollers clean up with soap and water. However, because itâ€™s tough and durable, consider oil-based paint for kitchen or bath cabinets.
