Powder Coating in 10 Simple Steps

When it comes to aesthetics and prolonging the life of your sheet metal product, powder coating is a great option to choose. Powder coating is a specific type of coating that can be used on most metals. The process involves free-flowing dry powder that comes in a variety of colors. This type of coating leaves a smooth protective finish on your sheet metal products.

Looking to take on a powder coating project? Here are a few simple steps to follow.

  1. Choose your object. Pick a metal object such as a bike frame that could use a fresh layer of protective paint.
  2. Prep work. If there are multiple parts, disassemble the entire thing as best you can. Clean the parts as best you can with soap and warm water or baking soda and let them dry.
  3. Outgassing process. This is a necessary and crucial step for preparing to powder coat. Turn your oven on at 425 degrees and bake your object for 30 minutes. This process releases any trapped gas.
  4. Sandblasting process. Sandblasting is necessary to create an adhesive surface for the powder coating to attach to. This process is done to smooth a roughened surface. For example, if there is rust anywhere on the part, sandblasting can remove the trouble areas.
  5. Clear off the object. After sandblasting, use a clean brush and wipe off the excess sand.
  6. Mask off uncoated areas. If there is any part of the object that you won’t want powder coated, be sure to use painters tape to “rope off” the areas.
  7. Powder coat your object. Finally! The time is now to powder coat your object.
  8. Settle the powder coat. Place your newly coated item back into the oven at around 375 degrees for 15 minutes. This will “set” the paint and help it form a strong case around the object.
  9. Cool time. You’ll want to leave the item on a cooling rack (such as one you might use for cookies, if your object is small enough) for an hour.
  10. Assemble and enjoy. Repeat these steps if you plan on coating multiple pieces. Assemble them back together only after they have completely cooled — and enjoy.

Of course, if this all seems too daunting of a task, you can simply call R.R. LeDuc Corporation for a professional powder coating job that will save you time and energy. You also won’t have to worry about making a mess in your house.
