Black Patina for Zinc

Q. What does one use to patina new zinc rolled sheeting and make it look like weathered zinc (blue-grey in finish)? I am an artist who currently works with copper patina, but would like to begin to work with zinc. I would be so grateful for any information.

A. You can use 200 gm iron chloride/1 lit water solution (cold immersion, cca. 20 min.)! Good luck!

Q. Thanks Goran,

What does "cold immersion cca 20 minutes" mean?

A. 1. I don't know which degreaser you use -- you can use Acetone [affiliate link to product info on Amazon] or pure alcohol!

2. "cca 20 min" = "approximately 20 minutes".

Good luck!

2006 -- this entry appended to this thread by editor in lieu of spawning a duplicative thread

Q. We are building a new home and have built a bathroom vanity out of wood which we covered in zinc. We ordered the zinc from a metal company. It came in a sheet and we sent it to a sheet metal company to cover it. I now have it ready to install, but it is still brand new and shiny. I know it will age with soap and water over time, but I want it to age now. What can I use to expedite this process?

Antiquing a Zinc Floor

April 3, 2014

Q. Hi; I am a painter but I have been asked to age a floor made up of zinc panels. I have done some research about using copper sulphate and hydrochloric acid but I am not sure do I dilute them? And also I need to protect the finish (bearing in mind it's a floor). Does anyone know of any good products? Any insight would be welcome. Thank you.

Pledge (Future) floor finish

April 9, 2014

A. If you are sure that your floor is made of zinc than you can use next formula: 2 heaping teaspoons copper sulphate, 1 heaping teaspoon kitchen salt, 1 cup of water. Dark gray to black finish.

Try Future floor finish (or Pledge - new name for same product). Hope it helps and good luck!

Adding patina to galvanized metal

September 17, 2019 -- this entry appended to this thread by editor in lieu of spawning a duplicative thread

Q. This is my situation. I have an outside galvanized metal plant container that I want to add a patina to. I have seen some galvanized containers that actually look like the old lead containers from England. Wondering how to achieve that result. Thanks.
