If you are in the painting business, you must become familiar with a variety of structural materials. It’s surprising the variety of items that are not made of wood but still require the occasional paint job to look fresh and new.
One perfect example is metal buildings. Many buildings are constructed of steel and metal buildings are often made of steel but there is a difference. Steel is an alloy and metal is a chemical element. While this may seem technical – it is important to know if you are going to be asked to paint something.
Common types of metal buildings are sheds or stand-alone structures. There are also metal homes as well. There are several reasons you want to paint a metal structure regularly. First, it will improve the aesthetics. More importantly, keeping a metal structure painted will better ensure its longevity and durability. Metal is subject to rusting. This is true whether it’s painted regularly or not. Rain and other environmental contaminants are the ‘enemy’ of metal buildings!
Just as you would inspect your home’s exterior for signs of wear and tear, the same should be done with all structures on your residential or commercial properties. As you walk around the structure look for evidence of paint that is peeling, flaking or otherwise lifting off the metal building. Too, examine the exterior for signs of rust and corrosion. Finally, determine if the exterior looks worn or chalky. Any of these are obvious indications the metal structure should be painted.
The process for painting a metal structure starts with removing the rust and filling any holes. There are multiple approaches to removing the rust. You may decide to purchase a chemical remover. But citric acid and abrasive tools are another way to remove rust from metal.
Next, prepare the surface by washing it thoroughly with soap and water. If you intend to use a power washer do so with caution. The surface of a metal building does not require the same amount of water pressure as a regular building. Be sure to rinse all of the soap off the metal, then let it air dry. Next apply the paint.
