Looking for Patina Finish on Wrought Iron 

.

I have a very small wrought iron factory and all my customers are demanding for Patina Finish. But I don't have the slightest of the ideas of this finish. This finish is also not available locally in the stores here. I currently powder coat all my products. Could you please guide me.

I have been looking for some advise for a long time and nobody could really tell me on this. I understand that the real patina cannot be attained on iron. How to give a faux finish of patina. I would also welcome other suggestions of different finishes that can be given on wrought iron.

Dear Sir,

I've been looking into the patina finishes as well...I've been seeing a lot of it done on HGTV..... Yesterday I was in JoAnn Fabrics and noticed that they carry a line of products that will give you the patina finish your customers are requesting....several colors too... Hope I've helped.....

Dear friend:

Over my years of experience in the field of industrial coating, I had come across various finishing on almost every surface including glass, tile, besides wood, metal etc. patina finish had always been one of my favorite finishes and it can be obtained on any surface including metal. In order to do patina finish, one must correctly choose the item to be patina finished. Not all items can look good in patina finish like an automobile or a simple chair. The product should have a minimum of some sculpted look like intricate turns and twists in design or a bust of a person. Basically, the product to be patina finished should represent a metal like a window grill but not a walking stick since a walking stick is never made of a metal.

Now, how to do a patina finish on a wrought iron furniture: first, clean the metal thoroughly with phosphoric acid to remove rust, dirt completely, This process will de-color the metal giving it a neat look. Next, dry the metal surface and use some mild solvent to remove the excess residue of the acid. apply epoxy primer preferably using spray method. then sand and spray paint first coat in brilliant white paint. then take some dark green stain in concentration and spray lightly on the dried white painted surface. Take a clean cotton waste dip it in mild solvent and squeeze the excess solvent back in container and then slowly dab on the surface. you will find some brilliant formation on the surface when the stain starts dissolving with the solvent and spreading itself out on the white background. Finally, finish with a matte lacquer mixed with green tint. use a little bit of white smoky spray on the dabbed surface before you use the final lacquer. continue spray the lacquer to achieve the desired tone. this is just one of the dozen different types of patina finishes. rest you can try and learn on your own. good luck.
