Why Do You Need A Paint for Metal Buildings?

Why Do You Need A Paint for Metal Buildings

There is a type of paint for metal buildings. Metal structures, like commercial buildings, often need metal-specific paint to withstand harsh weather. You can’t just use any type of outdoor paint or poor-quality paint. Metal surfaces need special attention. The question is: what makes metal-specific paint unique?

Bonds Well

Regular paint will only peel off after a short while, even if it’s fresh paint. You will need a specific type of coat for painting metal structures. It is this type of paint that bonds well to metal surfaces. You will find them useful for commercial buildings.

Protection Against Rust and Weather

Then there’s the rust issue. Metal and rust go hand in hand, unfortunately. But the right paint includes rust inhibitors. This is a big deal because it helps prevent rust from even starting. Think of it as a shield that keeps the metal looking good and strong.

Weather resistance is another top-notch feature. Metal buildings face everything—sun, rain, wind, you name it. Paint for these structures can withstand these elements. It helps protect the building from fading, chipping, or cracking under pressure.

Prevent Extreme Temperatures

Dark-colored paints will absorb more light and cause extreme temperatures. Yet, some metal paints reflect sunlight and keep the building cool. Choosing a lighter pigment can also improve the temperature of your building. It helps you worry less about air conditioning and save your wallet, too.

How Do I Paint Metal Buildings?

How Do I Paint Metal Buildings

Painting a metal building requires a few specific steps. This is to ensure that the paint adheres properly and lasts a long time. Here’s a general guide to help you through the process of your metal building painting project.


The first thing you need to do is clean your residential or commercial metal surfaces. Use a power washer to remove dirt, grime, and loose paint. If you encounter rust, scrub it off with a wire brush or sandpaper. Make sure to remove the previous coating or any loose paint for a nice smooth surface.

Surface preparation is crucial if you want a high-quality finish. A clean surface also improves paint adhesion and eases the painting process. You will also have to look out for damages or holes. Fill them up and consider using a rust-inhibiting primer to prevent further corrosion.


Once you are done power washing and scrubbing the metal surface, it’s time for the primer. Use a primer designed for metal painting projects. It must also be for the type of metal you’re painting on. For instance,  galvanized metal primer for galvanized surfaces.

After choosing the right primer, apply it onto the surface using a paint sprayer, roller, or brush. At Noble Painting, we recommend using an airless sprayer for a more accurate job. Priming is crucial for the exterior paint since it is the foundation. It also improves durability and enhances corrosion resistance.


Now, it’s time to find the right pain for metal surfaces. If you want your paint colors to last, we recommend using acrylic latex paint. Remember, the goal of your paint should be as a protective coating for your metal building. Consider using paint specifically designed to resist rust.

When you’re applying the paint, use a sprayer, roller, or brush. We recommend using a brush since it results in the most flawless finish. Apply at least two coats of paint to metal surfaces. Remember to allow enough drying time between the previous coat and the current one.


Always perform regular inspections and touch-ups, especially for metal roofs. Regular care will ensure that you can address issues to maintain the integrity of the paint job. Keep an eye out for chips, cracks, or signs of rust.

Additional Tips

  • Weather Considerations. Paint on a day with mild temperatures and low humidity levels. This ensures the best adhesion and drying times. Avoid painting in direct sunlight or on windy days.
  • Safety Precautions. Use the appropriate personal protective equipment (PPE). Your health matters when working with primers and paints. PPEs can include gloves, safety glasses, and respirators, especially in poorly ventilated areas.
  • Follow The Manufacturer’s Instructions. Always read and follow the specific instructions. The manufacturers provided this for the best results.

What Are The Best Paints for Metal Buildings?

Best Paints for Metal Buildings

When choosing paints for metal buildings, select products that will offer durability. You can also check for corrosion resistance and aesthetic appeal. Here are some of the best types of paints and coatings for metal buildings.

Acrylic Latex Paint

Acrylic latex paints are water-based. This type of paint is perfect because of its excellent adhesion to metal surfaces. They are flexible which helps them resist cracking and peeling. Acrylic latex paint also offers good color retention and resistance to UV rays.

Epoxy Coatings

Epoxy coatings provide superior durability and resistance to chemicals. This makes them ideal for industrial or commercial metal buildings. They are also excellent for protecting against rust and corrosion. However, epoxy can be more challenging to apply and may require professional equipment.

Polyurethane Coatings

Polyurethane paint is another great option for metal buildings. It works well for those exposed to harsh weather conditions. It offers excellent UV protection, durability, and flexibility. This makes it resistant to chipping and peeling. Polyurethane coatings can also provide a high-gloss finish. If you want the aesthetic appeal, it can enhance the appearance of the building.

Direct-to-Metal Coatings

Direct-to-metal or DTM paints are specifically formulated to adhere directly to metal without the need for a primer. They are extremely convenient and provide good protection against rust and corrosion. DTM coatings are available in various formulations including acrylics, alkyds, and urethanes.

Oil-Based Alkyd Paint

Oil-based paints offer good adhesion, durability, and rust prevention. They are a good choice for metal surfaces that undergo a lot of wear and tear. However, they take longer to dry and have a stronger odor compared to water-based paints.

Galvanized Metal Coatings

It is crucial to use paint that can bond to the zinc-coated surface for galvanized metal buildings. You will also have to take note of using specialized primers for this paint. Using both for these types of surfaces is necessary to ensure good adhesion. It also helps prevent peeling and damage.

Rust-Inhibitive Primers

Use a rust-inhibitive primer before applying the topcoat. Doing this can enhance the durability and corrosion resistance of the paint job. These primers aim to prevent rust and ensure that the topcoat adheres well to the metal surface.

Wrapping Up

When painting a metal building, adequate planning and preparation are key. The surface should be clean, dry, and free of rust. It should also be free of grease, and any old, flaking paint. We recommend applying a primer for the best adhesion and protection. Don’t apply a primer if you’re using a direct-to-metal product that doesn’t need it. Always follow the manufacturer’s instructions for the best results.

Also, when choosing paint for metal surfaces, always check the type of metal. You will need adequate planning if you want to achieve that flawless finish. After all, enhancing the aesthetic appeal of your property increases its value.
