Most people have at least some experience painting around the home. But once you start trying to paint outdoors, it's a whole different job. And if you're trying to paint a metal building that's outdoors, you're tackling a task that isn't quite as common. Fortunately, it's not an impossible job, but it is easy to make mistakes. Here's a look at some of the most common mistakes people make when painting the exterior of a metal building and what you can do to avoid them.
Mistake #1: Using paint you already have.
Using older paint isn't necessarily a mistake in itself, but the problem arises when you use paint that was intended for another surface. If you already have paint, there's a good chance it's basic wood or interior paint. If you're using the paint outdoors, you'll want paint that has certain qualities (like heat and water resistance or even insect resistance) you won't find in interior paint.
Mistake #2: Not sealing the paint.
If you're only used to painting inside your home, you've likely never had to seal paint. But if you're painting on the exterior of an outdoor metal building, you'll want to use sealant. Otherwise, the paint might peel off even if it was designed for metal. A sealant uses chemical bonding to make sure the paint adheres to the metal surface and stays there. And just like all paints are not created equally, neither are all sealants. You'll want to find the sealant that works best for the type of paint you're using, as well as the right one for the weather conditions in your area.
Mistake #3: Thinking the job is done.
If you paint the interior of your home, there's little maintenance required once you have the job completed. With a metal building, there are some things you'll need to keep an eye on. You'll want to make sure the metal stays clean, washing it with detergent and water at least once every six months. Inspect the surface for any holes or damage caused by rodents, and remove any debris like limbs or leaves. Check for patches of paint that may be peeling or fading, and repaint them as quickly as possible.
Of course, even if you make a point to avoid these mistakes, painting a metal building can still be a tricky task. That's why it's often best to just trust the job to the professionals. A painting contractor, like M & M Painting, has likely dealt with almost any scenario imaginable, so they know exactly how to get the job done right the first time.
