Galvanized metal is a widely used material in many industries due to its durability and resistance to rust and corrosion. However, it can be challenging to paint galvanized metal because of its zinc coating. In this article, we will guide you on how to spray paint galvanized metal in simple steps.

Gather Your Supplies

Before starting the process, you need to gather the necessary supplies. You will need a wire brush, sandpaper, a primer, paint, a spray gun, and a face mask.


Start by cleaning the surface with a wire brush to remove any dirt or debris. Use sandpaper to roughen up the surface to help the primer adhere. Wipe the surface with a clean cloth to remove any dust or debris.


Apply a primer that is suitable for galvanized metal. Spray a light coat of primer on the surface and let it dry for the recommended time. Apply a second coat of primer and let it dry completely.


After the primer has dried, use a fine-grit sandpaper to smooth out any rough spots or imperfections. Wipe the surface with a clean cloth to remove any dust or debris.


Choose a paint that is suitable for galvanized metal. Stir the paint thoroughly and strain it through a filter. Load the paint into the spray gun and apply a light coat of paint. Let it dry for the recommended time before applying a second coat. Repeat the process until you achieve the desired finish.

Clean Up

After you have finished painting, clean the spray gun thoroughly with the appropriate solvent. Dispose of any remaining paint or solvent properly.

Always wear a face mask and gloves when working with spray paint. Work in a well-ventilated area to avoid inhaling fumes.
