Cupric Sulfate comes in either an 8 ounce or 1 gallon bottle. This is a popular Patina for zinc that makes the sheets instantly darker and helps to give your zinc that desired aged look. Depending on the concentration of the patina and the method of application you can attain a variety of shades and textures on your zinc. In order to patina your zinc, first clean the surface with denatured alcohol or acetone to insure that it is free of oil, oxides, and plating residue as these will greatly affect the patina. To dilute the solution, add distilled water (up to 80% water/20% Cupric Sulfate) until you receive the desired concentration. You may then apply the patina by using spray bottles, brushes, or sponges or by burnishing the zinc with an abrasive pad. Once you have achieved the desired finish, you should seal your zinc with one of our sealants.
Please note that the color can vary greatly depending on different factors, such as concentration, brush strokes and method
of application. Depending on how concentrated you make your solution, we generally recommend one bottle of Cupric Sulfate Patina per sheet. In order to determine how concentrated you want your patina and how you would like to apply it, we encourage you to order some extra zinc on which to practice your application techniques.
