Powder Coating Versus Spray Painting

Paint finishing is a form of surface treatment that is used to impart a durable or decorative finish or sheen to a painted surface. It often refers to the textured coating that is applied after painting to protect, beautify, and add a smooth finish.

Paint finishing is the last step in the painting process. It can be a time-consuming process, whether done by hand or with a machine, depending on the type of finish needed. Ideally, a machine does the job faster and more efficiently.

Powder coating and spray painting are two of the most popular finishes available for a huge variety of products. However, you need to understand the difference between the two before you make a final choice for your project. With the help of paint finishing equipment, you can apply either of the two to a metal surface.

Spray Paint Vs. Powder Coating


With spray painting, the paint is applied in aerosolized form through pump devices at high pressure. For example, there are high gloss, eggshell, matte, and satin finishes. The best finish for your product will depend on the type of product. Ensure that you clean the metal surface and remove any oily residue or dirt before applying a coat of paint on it. 

Powder Coating

Powder coating is the most popular type of coating for metal surfaces. It is a dry film finish, which means it doesn't require any solvents or liquids. The powder particles are usually aluminum oxide, titanium dioxide, or zinc oxide, and particles vary in size from 2-5 microns. Powder coatings are popular because they are low-cost, low-viscosity, and easy to apply on a chosen surface. They can be used on different metals and everyday appliances such as refrigerators, stoves, washing machines, lamps, vases, tables, etc.

Which Is Better?

Powder coating is a colour-finishing method that uses powder instead of paint over a metal surface. It is thicker than spray paint, which will adhere to the surface better and longer. Using paint finishing equipment for powder coating provides better and more consistent results with a minor colour variation, also implying that powder coating is more durable than spray painting. Powder coating offers a more uniform finish because it dries slower than spray painting. Hence, spray-painting over a previously painted area could result in different shades with no uniformity, thus requiring a new coat after a couple of years.
