Before you attempt to paint your wrought iron gate, understand that metallic surfaces like wrought-iron are subject to rust when exposed to moist conditions. You must coat the wrought-iron gate with a special type of primer, formulated to seal existing rust and prevent future outbreaks. In addition, you should apply a topcoat of a particular type of durable paint, or you will ultimately end up with heavy flaking and peeling.

  • Pressure washer
  • Wire brush
  • 80-grit sandpaper

  • Masking tape
  • Red oxide primer

Tips and warnings

  • Do not paint directly over an unprimed iron gate, or the finish will peel.
  • Do not use an ordinary base primer on a wrought iron gate, or you will eventually end up with rust.
