Preparation is key to successfully painting your steel garage door. The first step is to clean the door thoroughly with a pressure washer. Be sure to remove all dirt, dust, debris, and cobwebs. Once the door is clean, give it a light sanding with fine-grit sandpaper to help the paint adhere better. Wipe away any sanding dust with a damp cloth.

If your garage door has any rust spots, you’ll need to remove them before painting. Use a wire brush or sandpaper to remove the rust spot down to the bare metal. Once you’ve removed the rust, apply a primer designed for use on metal surfaces. Follow the manufacturer’s instructions for best results.

Once you’ve prepared the surface of your garage door, you’re ready to start painting!


1. Thoroughly clean the door with a power washer. This will remove any dirt, dust, or other debris that could prevent the paint from properly adhering to the door.
2. Use a brush or roller to apply a coat of primer to the door. This will help the paint to better adhere to the door and also provide a protective barrier against the elements.
3. Once the primer has dried, apply a coat of paint to the door. You can use any type of paint, but latex or oil-based paints are best for steel doors.
4. Allow the paint to dry completely before opening or closing the door.


Before starting to paint your steel garage door, you’ll need to do some cleanup. This includes removing any loose paint, rust, grime, or dirt. You can do this with a power washer, a wire brush, or a stiff-bristled brush. Once you’ve cleaned the surface, you’ll need to rinse it off with clean water and let it dry completely.


If you follow these simple steps, you should have no trouble painting your steel garage door. With a little patience and attention to detail, you can achieve a professional-looking finish that will add curb appeal to your home.
