Magnetic paint allows you to transform any wall, tabletop or paintable surface into an area where you can attach notes, artwork or picture frames with magnets to reduce nail holes in your walls. Look for magnetic paint primer at home improvement stores. These paints are available in various sizes of paint cans or as a spray paint to simplify application. Another option is to purchase a magnetic paint additive--a dry powder that is mixed into any type of primer and applied to the wall. Magnetic paint will allow magnets to cling to the wall but it does not make the wall itself magnetic, so you do not need to worry about the paint causing damage to your home computer.
Tape blue painter's tape to the wall or other surface to outline the area you wish to paint with magnetic paint. Smooth the edges of the tape down with the side of your thumb to prevent the paint from leaking underneath the tape.
Paint the area with one coat of a magnetic paint primer.
Apply a second coat of the magnetic primer to the surface when the first coat has dried completely.
Cover the dry magnetic primer with any colour of latex paint to match your home decor.
Peel away the tape as soon as the paint is dry.
