Repainting powder-coated surfaces can be a challenge because the surface can be too smooth for paint to stick to. If the surface is not properly prepared, your new paint job may soon peel off. Powder-coating paint is usually applied as a dry powder to steel and aluminum surfaces and then baked on to give it a smooth, tough surface. You can often tell if a surface has been powder-coated because of its "powdery" appearance.

Things You'll Need:

  • Abrasive Nylon Pad
  • Power Sander
  • Degreasing Detergent
  • Paint Brush, Roller Or Sprayer

Clean the surface using a degreasing detergent mixed with water. Remove all the oil, grease and dirt from the surface.

Remove any white, chalky deposits and corrosion with an abrasive nylon pad.

Check for rust if you are repainting an iron or steel surface. If you find rust, use a power sander to remove it down to the bare metal.

Check the powder coating to see if it is flaking or peeling. Use a power sander to remove any peeling or flaking powder coat.

Rub any powder coat that is still on the surface with the abrasive nylon pad. This will provide a rough surface for the new paint to adhere to.

Wipe down the surface with a wet rag to remove any dust left from the previous steps.

Apply primer to any areas of exposed metal. This step should be done quickly, before the metal has a chance to oxidize. Use a type of primer designed for the type of metal you are painting. Use a brush or paint sprayer, depending on the qualify of finish you desire. Generally, a spray applicator will give you a more even surface. Allow the primer to cure for the length of time specified on the label. This normally will be 24 hours.

Paint the surface with a brush, roller or sprayer.
