For Your Home Metal Chimney Flue

Paint a Metal Chimney Flue

Project Scenario

Polly, a condo manager, wants to paint all the metal chimey flues at her complex. They get very hot to the touch. How should she tackle this painting project?


  • Wire brush to remove dirt and other contaminants.
  • Clean with mildew retardant solution if necessary. Let dry thoroughly.
  • Use a medium Scotch Brite pad to remove oxidation.
  • Wash surface to remove any sanding residue.


Primer and top coats are determined by how hot the chimney flue gets. Select from the list below.
