Difference Between Powder Coat & Paint

While both protect from the elements and corrosion, there are more differences than similarities.

Spray Paint

Powder Coat

Moderate durability but can be touched up

Extreme durability but cannot be touched up

Wet application

Dry application

Done on-site

Done off-site at a specialty shop

For all surface types – cured at room temp

Only high-temp objects – cured in an oven at 380 F or above

24 hours until usable

4 days minimum with shipping

Higher waste with overspray

Low waste

Low to moderate environmental impact

Low environmental impact

What is Powder Coating?

Powder coating uses an oven-cured dry powder to provide a thick, highly-durable coating for metal and other high-temperature resistant objects such as a fence, appliance face or deck furniture. The parts require disassembly and shipping because it is done offsite at a specialty shop.

Spray Painting

Painting uses a wet finish sprayed or electrostatically applied in a thin coat for both corrosion protection and appearance. Usually done on-site, it requires masking for overspray and curing times of up to 24 hours.

What is Powder Coating Spray Paint?

Professionals use two different processes for powder coating – electrostatic spray and fluidized bed dipping. Both methods require high temperatures and use a dry powder but come with some minor differences.

Differences Between Powder Coat Methods

Electrostatic Spray

Fluidized Vat or Bed

Metal only

Metal & high-temp plastics

Better for thin applications

Better for medium to thick applications

Oven cured after application

Preheated before dipping with oven cure after

  • Spray methods electrostatically charge the powder and objects. Objects are suspended and coated by a fine, low-pressure mist. The electrostatic charge attracts the powder to the object. Then, the piece cures in an oven to give it a lasting finish.
  • Fluidized beds use a large vat with air pumped up through the bottom to fluidize the dry powder. Objects are then preheated and dipped. The longer the dip, the thicker the coat. Most parts require additional oven curing as the final step.

Both have strengths and weaknesses while performing better under different circumstances. Here we’re comparing powder coats to standard paints. We’ll get into specialty paints like hardened enamels and electrostatic painting later.


Powder Coat

  • Extreme durability
  • Great for fencing, deck furniture, railings, and even some indoor appliances.


  • Not able to touch it up without stripping and redoing.


  • Able to apply extra coats for increased durability and for objects that require a very thin layer.


  • Though layering is possible, it’s not as durable for high-use projects.

Toughest & Most Durable: Powder Coat

Moisture & Rust Resistance

Powder Coat

  • Once completed, they are impervious to corrosion.


  • Improper preparation causes early failure which includes chipping and cracking. Once this happens, corrosion is quick to follow. You’ll then need to strip and reapply it.


  • Provides excellent moisture and corrosion protection when applied correctly and maintained.

  • Requires more upkeep.

Better Corrosion Resistance: Tie


Powder Coat
  • $50-$600 per piece
  • Materials included in application cost

  • Materials: $15-$50+ per gallon
  • Labor: $20-$100 per hour

Winner: Tie - Depends on Application

Better for DIYers

Powder Coat

While great for the hobbyist, is best left to the professionals for bigger projects as mistakes are tough to fix and the cost can quickly add up.

  • Pros:
    • Affordable DIY kits are available that include guns, ovens, and powders.
    • DIY kits range anywhere from $100 to $200 but are only useful for small objects.
    • Best for small projects like door handles and car engine parts.
  • Cons:
    • Easy to make mistakes and tough to redo.
    • Need large ovens for large objects, increasing equipment investment and space required.
    • Requires extreme detail during surface preparation.

Though painting can make a great DIY project, it can quickly turn into a disaster without the right preparation, materials or experience.

  • Pros:
    • Easy to do with rental equipment making even large projects accessible to DIYers.
    • Mistakes are relatively easy to correct.
  • Cons:
    • Requires a longer time investment in preparation and cleanup.
Best DIY Option: Paint

Environmental Friendliness

Powder Coating

  • Almost zero waste as any over-sprayed powder is collected and reused.
  • Almost zero VOCs.


  • Reused powders make color matching difficult.


  • Low VOC paints and options with lower environmental impacts exist.


  • Overspray and fumes mean it always has a higher environmental impact.

Best Environmental Option: Powder Coat

Maintenance & Length of Life

Powder Coat

  • Excellent length of life when applied properly.
  • Very low-maintenance.


  • Nearly impossible to touch up — requires a complete strip and redo when it begins to fail.


    • Easy to redo and touch up small spots.


  • Requires consistent upkeep for maximum durability and look.

Best Uses

Powder Coat

They can only be used on items that can resist the high temperatures of the curing process. Because of its incredible durability, it’s best used on high-use and high-traffic metal objects.

  • Outdoor objects — Metal fences, railings, handles, deck, and patio furniture.
  • Appliances with metal parts — range hoods, fixtures.


Because you apply paint at room temperature and on-site to almost any surface type, it is convenient for virtually any object.

  • Outdoor — siding, decks
  • Indoor — ceilings, walls, trim

Electrostatic Painting vs. Powder Coating

Electrostatic Paint


Applied on-site or in a shop with wet paint

E-Coating or Powder Coating

E-coat refers to using a water-based solution that contains a paint emulsion. Electric voltage passed through the solution causes the paint to attach to the metal in an even layer. Just like with powder coating, you’ll finish the object in a curing oven.

It’s a better choice when covering an object that requires a thinner protective shell with tough-to-reach areas. For example, the hinges on a door require clearance to move correctly. A thick layer stops it from functioning.

Baked Enamel vs. Powder Coat

Powder Coat

Baked Enamel

Slightly tougher finish

Tough finish

Evenly applied

Shows runs and brush strokes



A type of wet paint, baked enamel uses high temps to cure it for a more durable finish.

Despite the differences, both products rely heavily on the pretreatment of the object, the type of resins used, the quality of the product and the quality of the professional applying it. A high-quality enamel applied correctly to a properly prepared substrate is better than an incorrectly-done powder coat – and the same applies in reverse.

Chrome Powder Coating versus Chrome Plating

Chrome powder coating is a process of adding a chrome-like finish to a metal part. Typically done to engines and other car parts, it provides a protective finish at a rate 70 to 90 percent cheaper than plating.

However, it doesn’t perfectly replicate an actual chrome, or chromium, plating process. If you’re looking to restore a classic car or historic home to its original condition, opt for chrome plating.

    Hi, my name is Andre. I am making a paper about metals.

    Do you happen to know if iron metal powders where used in paints like back in year 2000?, or you cant find any iron metal powders in a regular building at that time maybe?.

    Best regards,
    Andre ​
