You can paint a new STEEL GARAGE DOOR if the manufacturer does not offer the color you desire. We recommend that you paint a new garage door before installation. By using a good quality LATEX PAINT it will also last longer. Whatever you do, DO NOT use an oil-base paint, it will bubble and peel off the door.
When painting your garage door, always use a soft-bristle brush, sponge or low-pressure sprayer. Start by cleaning the door by washing it with a solution that combines 1 cup of detergent (less than 0.5 percent low-phosphate) with 5 gallons of warm water. Then thoroughly rinse with clean water and let dry completely. If there are any minor surface imperfections, such as scratches that don’t go through to the metal substrate, you can prep by lightly sanding the scratches smooth. If there are gouges in the topcoat of the garage door that do show bare metal, lightly sand the area and apply a primer specifically designed to protect exposed galvanized steel from corrosion.
Once the garage door has been properly prepped, it must be painted within 24 hours. Apply a uniform coat of well-mixed, high-quality latex exterior house paint on a dry garage door. Paint early in the morning to minimize uneven drying by the sun.
