Best Way to Repaint a Metal Building

Metal buildings can be a great investment. Not only are they affordable, but they also last a long time. However, over time, the paint on your metal building may start to fade and chip. When this happens, it’s time to repaint your metal building! In this blog post, we will discuss the best way to repaint a metal building so that it looks new again.

Prepare the Surface

When preparing your metal building for a new coat of paint, there are several important steps that you need to take. The first step is to remove any rust spots on the surface of the building. You can do this with 80-grit sandpaper or a wire brush. This will ensure that the rust doesn’t spread underneath the new coat of paint, leaving you with even bigger problems down the road. 

Then make sure that the surface of the building is completely clean and free of any dirt or residue. You can do this by washing the surface thoroughly with a mild detergent or a specialized cleaning solvent. If you have the option, it would be beneficial to use a pressure washer. 

Next, it’s important to sand down the metal until it feels smooth and even. This will ensure that the paint has a good surface on which to adhere. Allow the surface of the building to dry completely before moving forward. 

Apply Primer

One of the most important steps in painting a metal building is to use a primer. A primer is a special type of paint that helps to bond the new paint to the metal surface. Without a primer, the new paint is likely to peel and flake over time. In addition, a primer helps to prevent rust and corrosion, which can quickly damage a metal building. 

While it may seem like an extra step, using a primer will save you time and money in the long run. You can apply primer with either a paint sprayer or roller. Just be sure to clean the roller thoroughly before using it to apply paint. 

Apply Your Paint

Most people don’t realize how easy it is to apply paint to a metal building, as long as you have the proper tools. Once the primer is dry, you can then begin painting the building. It’s important to use a brush or roller specifically designed for painting metal. 

These brushes and rollers have special bristles that are designed to grip the paint and apply it evenly to the surface. When painting, always start at the top of the building and work your way down. This will help prevent drips and runs. Once you’ve finished painting, you can then add any finishing touches, such as trim or detailing. With a little bit of time and effort, you’ll be able to transform any metal building into a work of art.


Painting a metal building may seem like a daunting task, but it’s actually quite simple. Just be sure to take the time to prepare the surface and use a primer. With the right tools, you’ll be able to apply paint evenly and easily. In no time at all, your metal building will look brand-new again!
