Residential and Commercial Metal Pole Building Painting | DJ’s Painting

Metal pole building painting is often an over looked project. Most pole buildings have a metal outer shell, meaning the walls, roof, and all trim are steel or aluminum.  90% of the time, this metal is either a powder-coated, baked paint finish or a galvanized coated finish. These are great for long term outdoor exposure.  Both systems hold up well to the UV and moisture over time and do a great job of protecting the metal from oxidation.

Factory finished metal is not a lifetime coating, but in fact may last a decade or maybe two. We can now talk about how to maintain and extend its lifespan.

First, the surface needs to be clean and chalk free. The best way to achieve this is to pressure wash the area completely. Then, the next step is to apply a complete prime coat, the material that best primes will vary depending on the situation we are dealing with. For the top coat, you have some options based on desired results. For best color and gloss retention, a 2 part aliphatic urethane top coat is best and should last 10 plus years. For a more economical coating, a DTM or waterborne single component urethane will work well and give about 5 years of good color retention. It is a good idea to stay on a re-coat cycle of about 5 years for single component top coat systems and 10 years for 2 component top coat systems.

Bottom line is this, if you stay on top of the maintenance painting of your metal or steel pole building it will last a lifetime!
