Metal buildings are prized for their durability and minimal maintenance requirements. Still, constant exposure to the elements can cause the exterior paint to deteriorate and fade, leaving the metal vulnerable to rust and other damage. If the paint is starting to crack or peel, the walls can seem unevenly faded or have a chalky appearance, or you see patches of rust, it's time to repaint the building. To ensure the paint goes on smoothly and restores the appearance of the building, follow these tips. 

How to Successfully Paint a Metal Building 

1. Power Wash the Exterior

To ensure you have a clean surface for painting, thoroughly clean the metal building's exterior with a power washer. Getting rid of dirt and grime is important, but it's even more vital if the metal has a chalky appearance. As older paint starts to break down, it can turn into a powdery substance that makes the metal seem faded. If you run your hand over the wall and it comes away with a white power on it, it's a sign the paint is chalking. Power washing can remove most, if not all, of the residue, leaving the metal ready for new paint.

2. Remove Imperfections

Before repainting the metal building, take time to scrape off any flaking or peeling paint. You also need to smooth out any rust spots using a wire brush or sandpaper. For large or stubborn areas, a sandblaster may be the most effective tool. Eliminating these imperfections ensures an even finish for the new paint.

3. Prime Exposed Metal

To ensure the new paint adheres to the building and lasts, all exposed metal and rust spots need to be primed first. Applying the right primer creates a base that the new paint can stick to while also preventing further deterioration to the structure. Make sure the primer is completely dry before painting over it. 

4. Use a Sprayer

When painting a metal building, it's better to use a sprayer than a brush or roller to ensure even coverage. Choose a paint designed specifically for metal buildings to ensure longevity. This type of product will also help the finish withstand the elements.
