Almost every home or building has at least one uneven wall. Similarly, many homes have highly textured or bumpy walls. Painting over these bumpy walls can be difficult. Unless you know how to paint over uneven or textured walls, you may end up spending a lot of time painting multiple coats of paint on your walls to reach into one or two areas. The secret to getting good coverage on bumpy walls is a good-quality high-nap paint roller. The heavy texturing on your walls can be easily painted over with the right paint roller.
Pour a small amount of painting primer in a paint tray. Cover flooring and furniture in the room with dust sheets.
Spread the primer over the uneven walls with a high-nap paint roller. The thickness of the high-nap roller will ensure good coverage of the bumpy walls. Let the primer dry per manufacturer directions.
Pour latex paint into a paint tray. Cut-in around the edges of the room with a paintbrush. Cover the main area of the walls with a high-nap paint roller. Transfer the paint to the bumpy walls in a "W" shaped pattern. Allow the paint to dry for three to four hours.
Apply a second coat of paint to the walls with the high-nap roller. The second coat of paint should cover the walls completely. Let the paint dry overnight before hanging anything on the walls.
