How Long Does Powder Coating Last?

There are many benefits of powder coating over paint and other finishing techniques. It only requires one coat for enduring clean results.

Finishes are customizable and can match any color, texture and finish. Powder coating is environmentally friendly with virtually no waste and requires no solvents or toxic chemicals. Most importantly, powder coating is extremely durable and long lasting.

How long does powder coating last? The simple answer is up to 40 years.

There are many factors that determine the lifespan of powder coating. It starts with preparation.  The surface to be coated, called a substrate, must be clean so that the powder coating adheres properly electrostatic bonding. Proper pretreatment will strip existing coating and corrosion. If this process is subpar, the powder coat might chip and shorten its lifespan.

Other factors that affect the lifespan of power coating are:

  • Environmental and weather factors can also impact the lifespan of powder coating. Exposure to salt water, blowing sand, and extreme hot and cold temperatures can cause coatings to wear more quickly. High humidity can also lead to early corrosion.
  • Exposure to hazardous compounds including gasoline and caustic chemicals also affect powder coating’s durability.
  • Abrasive cleaners such as steel wool, wire brushes or scouring pads should not be used on powder coated products. Improper care will cause powder coatings to degrade more rapidly than normal.

Not all types of powder coating are appropriate for all projects. For example, epoxies are durable and resistant to corrosion and harsh chemicals. They are not appropriate for high UV exposure, so products for indoor use are best. Fluoropolymers are incredibly resistant to most types of weathering making them a superb choice for outdoor use. Polyesters are available in a range of colors and glosses, and they are also resistant to corrosion, chemicals and UV rays. Urethane powder is similar to polyester but has a slightly better chemical resistance. Ask the experts at glosses and colors, which makes them a prime choice for any sort of indoor or outdoor project. Additionally, they’re resistant to corrosion, chemicals and UV rays.
