Applying a Second Coat of Powder Coating

By
Sometimes, you have to apply one coat of powder over another. You can recoat with most powders, though you’ll probably face common problems of poor electrostatic attraction and poor inter-coat adhesion.


Techniques to help with the application of a second coat:

  • Ensure a proper ground in your powder coating system
  • Lower your gun voltage
  • Preheat the part
  • Clean parts thoroughly before recoating
  • Slightly increase cloud density
  • Increase gun to part distance

If you need to apply a second coat, it is important to make sure part preparation is consistent. As with any new coating job or procedure you do, always test the procedures thoroughly to work out application techniques and find application problems before you begin to produce the powder coated part.


Please contact us today to speak with one of our professional service technicians. We can help you with application questions or any of your powder coating needs.
