Can You Paint Galvanized Steel?

A common question at Tampa Steel & Supply is, “can you paint galvanized steel?” This blog post will explain what galvanized steel is, if you can paint galvanized steel, the tools and materials you would need, and the four easy steps to paint galvanized steel.

Can you Paint Galvanized Steel?

Galvanized metal is metal that has been galvanized. Galvanizing is the process of applying a protective coating to steel or iron. The coating is made from zinc and is used to halt the formation of rust. Galvanization is important because it provides long-lasting protection for steel and iron products.

That’s all great, but can you paint over galvanized steel? The short answer is that it may be challenging to do so, but yes! With the right paint and tools, you can paint over galvanized steel.

Supplies You’ll Need for Painting Galvanized Steel

You will need many supplies to paint galvanized steel. They include:

  • Ammonia
  • Sandpaper
  • Metal paint primer
  • Paint specifically made for galvanized metal
  • Cloths

How to Paint Galvanized Steel in 4 Easy Steps

1. Prep Your Steel by Washing It

First, wash your metal twice. Start with soap and water and wash off any dirt and debris on your surface. Next, dry it with a rag, then wash it with a weak solution of water and ammonia. From there, you’ll need to dry it again. We recommend using a cloth to dry your metal to speed up the process.

2. Sand The Metal

Next, sand down your metal with some sandpaper. Try to find the strongest sandpaper you can find. This will help you sand down your metal quickly. Once you’ve sanded, wipe down your metal with cloths to ensure you get all the dust off.

3. Add Your Primer for Painting

For the third step, you need to add the primer for your paint job. Please ensure this is a special primer used specifically for galvanized steel. You may be wondering why you need a special primer. Due to the process of making it galvanized steel, the coating requires a special primer.

Make sure to read the directions on the primer and use it as directed, as directions are different for every primer. First, cover the entire surface of your metal, starting at the top and working your way down. It is best to work section by section. From there, let the primer dry and inspect the steel to ensure it is covered and evenly distributed.

4. Apply Your Paint Made Specifically for Galvanized Surfaces

Start painting, let it dry, then inspect it to ensure it looks good.

For the last step, you can begin painting. First, ensure that you have paint specifically made for galvanized surfaces. Once again, a specific paint type is needed because the metal is made with a zinc coating.

Start painting coat by coat, letting each coat dry to ensure even coverage. Apply multiple coats of paint to achieve the color results you’re looking for. From there, let the paint dry, and admire the results of your hard work!
