How To Spray Paint A Metal Garage Door

If your metal garage door has seen better days, a fresh coat of paint can do wonders to improve its appearance and protect it from the elements. Spray painting is a relatively quick and easy way to paint a metal garage door, and it can be done with just a few basic tools and materials.

Tools and Materials You Will Need:

Safety glasses
Respirator mask
Sandpaper (120-grit and 220-grit)
Tack cloth
Metal primer
Spray paint (choose a paint that is specifically designed for metal)
Paint sprayer
Drop cloths

Step 1: Prepare the Garage Door

Begin by removing any dirt or debris from the garage door with a damp cloth. Then, sand the door with 120-grit sandpaper to roughen up the surface and create a good bond for the primer. Once the door has been sanded, wipe it down with a tack cloth to remove any dust.

Step 2: Apply Primer

Apply a coat of metal primer to the garage door, using a paint sprayer. Make sure to follow the manufacturer's instructions for the primer, and apply a thin, even coat. Allow the primer to dry completely before proceeding.

Step 3: Apply Paint

Once the primer has dried, you can begin applying the paint. Use a paint sprayer to apply a thin, even coat of paint to the garage door. Allow the paint to dry completely before applying a second coat. If necessary, apply a third coat of paint for a more durable finish.

Step 4: Clean Up

Once the paint has dried, remove the drop cloths and clean up any paint spills. Allow the garage door to dry completely before opening and closing it.
