How to Improve the Look of Old Laminate Countertops for Less

Measure the countertops carefully. One can of spray paint covers between eight and 15 square feet, depending on the coverage depth and how many coats you apply to the countertops.

Wash the countertops and backsplash with dishwashing liquid and water. Rinse them with clear water and allow them to completely dry before proceeding.

Sand the countertops and backsplash with fine sandpaper. You want to take the gloss off of the surface so the primer adheres to the old finish. Wipe the counters with a tack cloth to remove all traces of dust.

Mask the wall and other areas with painter's tape. Remember that spray paint drifts, so cover the wall at least one foot above the countertops and backsplash. Also mask around and over the sink and faucets; use newspaper or plastic to protect the sink.

Roll on two coats of primer in an appropriate color. For example, if you want a granite-look finish with a blue undertone, have the primer tinted to a light blue-gray color. Allow the primer to dry for at least 24 hours.

Shake the can of stone spray paint until the ball rattles freely, or at least one minute. Lightly spray the countertop with the first coat. Continue shaking the can as you work. Allow 15 minutes between coats. It may take four or five light coats of paint to reach the coverage desired. Allow the paint to dry for at least 24 hours.

Stir the can of satin or gloss polyurethane carefully; try to avoid making bubbles. Brush two or three coats of the polyurethane over the countertops. Allow the polyurethane to dry completely before using the kitchen.
