Galvanized metal is uniquely coated with zinc to protect against rusting. You can use it to construct various objects, such as sheds, fences, and mailboxes. You must use specialty paint formulated to cover galvanized metal.

Our team at The Painted Horse in Lexington, Kentucky, wants to ensure that whatever painting project you are working on has everything you need to achieve a professional outcome. Today, we share some best practices for painting galvanized metal and the best paint and primer for these projects.

How To Paint Galvanized Metal

Because galvanized metal prevents rust, it can be more challenging to paint than other surfaces. To ensure successful application, properly prepare the metal and use appropriate products. Read further for a simple step-by-step guide on prep and paint galvanized metal.

Clean the Surface

If you are painting new galvanized metal, wipe it down with white vinegar. This will allow for better paint adhesion. When painting weathered metal, use a degreaser and remove old rust spots. Avoid sanding galvanized metal, as it will permanently damage the surface. Rinse the surface off with a damp cloth.

Prime the Surface

A previously painted galvanized surface does not necessarily need primer, as the existing coat of paint acts as a primer. For an unpainted surface, apply the primer and let dry. You can also consider a second coat of primer for ultimate coverage and adhesion. Refrain from using oil-based primers.

Paint the Surface

Next, paint the surface with a paint designed explicitly for galvanized metal. Refrain from using alkyd-based paints.

Allow to Dry and Repeat

Before applying a second coat, allow the first coat to dry. Refer to the paint label or data sheet for dry and cue times.
