There are a few ways to finish zinc countertops. The most common, and best choice, is a matte finish. This allows the metal to adapt and react to its environment once in use.
Patinas can be done during production and add a base color or pattern. This is an additional step that mimics what will happen naturally. Likewise, after the patination process, the metal will still react to its environment so keep in mind that the patina is not permanent.
