Treating copper flashing | Ask The Experts Forum

Guest User 5/24/2004	How can I GET that green patina..I've had my copper flashing for approx. 8 years and still just have a slight green and a rather dull look...you'd never know it was there. I've heard that uric acid will do the trick but where do I find it? Thanks, H.P.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/2019/find/
Todd Miller Isaiah Industries, Inc. 5/24/2004	A Google search for something like "copper patina chemical" should yield several possibilities. There are several chemicals marketed for that purpose. I do not believe that uric acid is what you're looking for.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/2020/find/
