Here, I will show you how to paint galvanized metal so your new paint job will look great and last for years.
How to Paint Galvanized Metal? A step-by-step guide
Galvanized metal is coated with a layer of zinc to protect it from rust and corrosion. However, this zinc coating can break down over time, leaving the metal vulnerable to rust and corrosion.
Painting galvanized metal is a great way to protect it from the elements and extend its lifespan. Here is a step-by-step guide on how to paint galvanized metal:
Step 1: Prepare the surface
Before starting the main job, ensure that your paint surface is clean and free of any dirt, grease, or other contaminants. You can do this by giving it a good scrub with soapy water and a stiff brush.
Step 2: Remove old paint
If you’re painting over old paint, you must remove any loose or flaking paint before you start. You can do this by sanding the surface with a medium-grit sandpaper. Once you’ve sanded the surface, wipe it down with a damp cloth to remove any dust. If you paint on a new one, you can start with the primer.
Step 3: Apply primer
Use a zinc-based primer to coat the surface of the galvanized metal. This type of primer will help to prevent the paint from peeling or flaking in the future. Apply the primer with a brush or roller, and cover the entire surface evenly.

Step 4: Choose the paint
Choose a paint suitable for zinc-based primer, and for the surface, you’re painting. You’ll need to use metal paint if you’re painting a metal surface. You can use acrylic or oil-based paint.
Step 5: Apply the paint
Once the primer is dry, you can start to apply the paint. Use a brush or roller to apply the paint evenly, and make sure to cover all of the primed areas. If you’re using a spray paint, hold the can about 30cm away from the surface and apply the paint in a steady, even motion.
Step 6: Allow the paint to dry
After you’ve applied the paint, you’ll need to allow it to dry completely. This usually takes about 24 hours. Once the paint is dry, apply a second coat if you wish.
