Vacuum walls, corners and the ceiling edge to remove dust and cobwebs.
Check walls for any holes or cracks. Repair with spackle and a putty knife according to package directions. Allow the repairs to dry completely.
Sand the areas smooth and wipe with a tack cloth to remove dust.
Gently scrape all loose and flaking paint with a hooked scraper. The hook is especially useful in corners.
Sand lightly and wipe with a tack cloth to remove dust.
Prepare the walls by mixing cleaning agents together in a plastic pail and scrubbing all wall surfaces. The mixture works well to remove mildew and molds. Allow the room to dry completely.
Tape off any wood trim around windows and doors. Remove electric outlet covers and switch plates.
Tape off any surfaces that abut or touch the walls. This might include: ceilings; tilework; heaters; baseboards; vanity tops and sides; mirrors; tub or shower edges; water and drain pipes; and the toilet tank.
Lay drop cloths over all fixtures---sinks, vanity, toilet, shower/tub and flooring. Tape plastic bags over the light fixtures.
Stir the paint well and pour it into the painter's tray.
Using the sash brush, begin painting around fixtures, door and window frames and anywhere too narrow for the paint roller to access.
Let the paint dry, then repeat for complete coverage.
Refill the painter's tray as needed and begin to paint the walls with the roller. Paint the walls by rolling in a "W" pattern, overlapping as you go. Spread the paint evenly.
Let the paint dry completely, then repeat the previous step.
Remove the painter's tape and touch up any small areas that were missed.
Clean up any spatters with detergent and warm water.
