Pandemonium Copper Coating Made Easy

oatings, there are all kinds of them. This one is new to me, and I thought that I C would show you all. This is a patina coating that gives an old copper look or a heavily rusted oxidation look. It is extremely easy to do, so let’s get into it.

Copper sulfate crystals are used to kill weeds in ponds and roots in apply patina coatings to bare steel. This can be found in most home improvement stores. I start by mixing a bit of copper sulfate in water until it is dissolved. The solution will be used to coat bare steel. I used a water bottle to mix my solution in. The steel must be clean and free from any oils or mill scale. I used a Scotch Brite pad and some acetone to get everything cleaned up. You can also sandblast your parts. Just make sure you are working with clean steel parts.



for the copper coat to appear. Once the part is coated, you will then rinse it off with water to neutralize it and then lightly pat dry with a paper towel. Now you have a patina coppercoated steel part.


We are going to oxidize the copper coating. Spray some peroxide onto the copper surface. Things will start happening very quickly. So, you may want to do some testing to see some of the different results you can achieve. Pat dry with a paper towel, then rinse and pat dry again. The peroxide will give an orange heavily oxidized look. Once done with the above coating methods, you will need to put on a top coat of some sort. You could spray on some clear coat or use some type of oil to protect and preserve the finish. I like to use Flax oil; you can buy this at your local grocery store. Lightly rub it on with a paper towel, apply as needed in the future when the surface begins to look dry. Flax oil will allow the patina to age gracefully over time. So, there you have it oxidized copper coating… There is no right or wrong way to do any of this as long as the basics apply, so be creative and let your imagination be your limitation.
