Can I paint my new steel Apple garage door?
All Apple residential steel garage doors are already painted with a baked-on finish. No additional painting is required. If you want to apply another color, however, the following steps are required. NOTE: Only paint the exterior of the door while it is in the closed position.
Use the following solution, with a soft bristle brush, to remove mildew and other surface contaminants:
1 cup household Spic n Span® detergent
5 gallons warm water
Rinse thoroughly with water. Use a powder cleanser like Comet®, diluted with water, with a soft bristle brush, to prepare the surface for better paint adhesion. Do not use sandpaper, deglossers, or liquid sandpaper to prepare the door surface. Rinse thoroughly with water and allow to dry. Use a high quality acrylic latex exterior paint. Apply according to manufacturer's instructions. Do not use oil-based paint or any "rust-inhibitive" paint. Do not paint in direct sunlight or when surface is warm to the touch. Lap marks will result. Brush application is recommended. Avoid getting paint on any gasket seals between door sections.
