What To Know Before You Have Something Professionally Powder Coated

Posted on: 7 January 2016

Whether you've decided to refinish metal shelving or a patio furniture around your home, there are a few things you should know before you have something professionally powder coated. Powder coating offers a great way to refinish metals, as it can offer a vibrant, durable, and more permanent alternative to paint and lacquering treatments. So if you're ready to get started with coating around your home, here's what you should know first.

The Possibilities are Endless

Though powder coating still uses paint, the finish is set by electrostatic interactions between dry paint molecules and the surface that's being finished, either by spraying or dipping the item being coated. The electrostatic interaction forms a continuous layer that essentially bakes the paint onto the surface for a highly durable finish. Like regular paint, you can increase the depth of the finish by layering colors that are opaque and transparent, integrating metallic flakes for sparkle, or treating one color with a second gloss coat. You can also choose between matte and high gloss results, so you'll end up with an end result that's personalized to meet your design needs to a T.

The Specifics Make a Difference

Beyond color and finish options, you should also understand that many types of metals can be powder coated, so you can finish almost anything metallic that you have around the house. You'll have to consider specifics though when having something powder coated, as each type of metal and coating demands specific treatments and conditions during the process for the best finish. So if you're working with a professional, they may require additional curing time, coating techniques, or preparations to get a uniformly beautiful result.

Maintenance Matters

Because a powder coated finish is a continuous layer that is highly resistant to heat and environmental elements, you'll have a more permanent finish than paint, even if you use a clear coat. Powder coating is layered in a thickness according to the manufacturer's specifics on the paint, number of layers used, the type of surface you're coating, and whether the finished product will be used indoors or out. Thicker coatings are used for some types of orange and almost all white coats, as well as objects exposed to the outdoors, whereas thinner applications are used for indoor conditions and most color layers.

Regardless of the finish and conditions it's exposed to, you'll have to routinely wipe down the coated surface with a soapy solution, and then follow with a water rinse. Wiping down your powder coating often will remove dirt and debris that can interact with the coating over time, which can sometimes lead to pitting or spot degradation.
