POOR GALVANIZED METAL ADHESION - EXTERIOR

Paint that has lost its adhesion to a galvanized metal substrate.

Causes

  • Improper surface preparation, such as inadequate removal of rust or oils.
  • Failure to apply a primer before application of an oil-based or vinyl latex paint.
  • Failure to sand baked-on enamel finishes or glossy surfaces before painting.

Solutions

  • Remove all loose, peeling paint down to the bare metal. Any rust on the metal should be removed with a wire brush.
  • Prime bare surface with a galvanized metal primer.
  • Repaint with a high-quality exterior paint.
