Painting vs. Powder Coating: Which is Right for You?

When it comes to finishing metal surfaces, there are two main options: painting and powder coating. Each process has its own advantages and disadvantages. Whether you’re trying to decide on a finish for your outsourced parts, or maybe even looking to add a finishing application to your facility, it’s important to choose the right process for your parts.


Painting is the more traditional method of finishing metal. It involves applying a liquid paint to the surface, which then dries to form a protective layer.

The advantages of painting include:

  • It is relatively inexpensive.
  • It is easy to do yourself.
  • Easily touched up or repaired.
  • There are many different colors and finishes available.

The disadvantages of painting include:

  • Paint can be difficult to apply evenly, especially on complex shapes.
  • Paint can chip and peel over time, especially if it is not properly applied or maintained.
  • Paint can contain harmful solvents and VOCs.

Equipment needed for painting:

  • Paint booth (if painting indoors)
  • Paint mixing room (if mixing specific paints)
  • Paint sprayer/pump plus gun(s) and hose(s)
  • PPE

Powder Coating

Powder coating is a somewhat newer method of finishing metal that is becoming increasingly popular. It involves applying a powdered coating to the surface, which is then cured using heat.

The advantages of powder coating include:

  • It is more durable than paint and resistant to chipping, scratching, and fading.
  • Excess powder can be reused, creating less waste.
  • It can be applied to a wider variety of metal surfaces.
  • It is environmentally friendly, as it does not contain harmful solvents or VOCs.

The disadvantages of powder coating include:

  • It is more expensive than painting.
  • It cannot be applied to complex shapes without special equipment.
  • It requires more equipment and facility space.

Equipment needed for powder coating:

  • Powder coating booth
  • Curing oven
  • Racks, hooks, or other fixtures
  • Powder gun(s)
  • PPE

Which is Right for You?

The best way to decide which finishing method is right for you is to consider your specific needs and budget. If you are looking for a low-cost option, with a variety of colors and finishes, painting may be a good choice. Painting is also an ideal application for large items and mobile coating jobs. However, if you need a more durable finish that is resistant to damage, powder coating is the better option. Powder coating is an ideal application for small and medium sized parts.

Below is a summary of the main differences between painting and powder coating:

   Characteristic    Painting    Powder Coating
   Cost of Utilities    Less Expensive    More Expensive
   Equipment Costs    Less Expensive    More Expensive
   Cost of Materials    More Expensive    Less Expensive
   Durability    Less Durable    More Durable
   Ease of Application    Easier To Apply    More Difficult to Apply
   Color & Finish Availability    Wide Variety Available    Limited Variety Available
   Waste    More Waste    Less Waste
   Environmental Impact    More Harmful Components    Less Harmful Components


Other items to consider when choosing are:

  • The type of metal being finished. Some metals, such as aluminum, are more difficult to paint than others.
  • The environment in which the finished product will be used. If the product will be exposed to harsh weather or chemicals, powder coating is a better choice.
  • The desired finish. Powder coating can produce a wider variety of finishes than painting.
  • The budget. Painting is generally the less expensive option, but powder coating may be worth the investment if you need a more durable finish.

In conclusion, both painting and powder coating have a place when it comes to finishing. Each have their strengths and weaknesses. Regardless of your choice, both can provide a fantastic finish on parts and equipment.
