Introduction: Faux Copper Patina Paint Finish

I was building a bench power supply from an old ATX power supply, and wanted something unique. I went with a minimalist Steampunk theme.

Step 1: PREP

Paint Selection
  • Copper colored hammered finish spray paint
    • I wanted the varied surface that hammered paint has
  • Light moss (green) colored spray paint
    • for the patina
  1. Disassemble the power supply enclosure
  2. Remove any stickers and/or labels
  3. Lightly sand the enclosure
  4. Clean to remove dust


Follow the directions on the spray can for applying the paint.

I painted the inside only because I thought it would be visible through the air vent.

Step 3: PATINA

I tried a couple of different ways of applying the light green paint. Spaying the paint directly onto a sponge worked best for me.
  1. Spray a fair amount of paint onto a sponge
  2. Lightly dab the sponge onto the project to reach the desired effect
  3. repeat until finished


Hmmm! I like it!

I like the way it turned out. Subtle Steampunk. 

If I were to do it over, I would use less green to let of the copper color show. I would include some kind of staining around the screws, model builders call it weathering.


Use light blue instead of green for the patina effect.
