Traditional Midnight Black Patina reacts on aluminum, bronze, brass, copper, iron, steel (not stainless), and
zinc/galvanized. This patina is notable for its striking aged black finishes, fast reaction times, and excellent
durability. Also, rust is slower to develop compared to other black patinas which allows for more flexibility
when applying a sealer.
On aluminum, apply the patina at full strength. It reacts quickly on the first coat to produce a durable
grey/black finish. Additional coats deliver a solid black that does not rub off easily.
On steel, apply Traditional Midnight Black Patina at full strength. Just one coat makes a blue/black oil slick
finish. Extra coats darken the patina.
On zinc/galvanized, apply the patina at full strength to yield a fast bronze/brown finish. Reapplication results
in even more warm color with great adhesion.
On bronze, brass, and copper, we recommend diluting with distilled water at a 1:1 ratio. You may need more or
less water depending on the project. The first coat produces a beautiful brown patina. Second and third coats
darken the patina to a rich antique black.
1. We recommend sanding or sandblasting before cleaning for better reactions and more consistent results.
You must clean the metal after sanding, sandblasting, or touching with bare hands. Clean the surface with
Sculpt Nouveau Metal Cleaner and Degreaser and a Scotch-Brite pad for 2 min. Rinse with water. DO NOT use
Acetone or any other solvent based cleaner.
2. Apply Midnight Black Patina with a brush, roller, sponge, or sprayer. The application method you choose can
show characteristics of that method in the finish, such as brush strokes or roller marks. Spraying is the most
common application method. The typical reaction time is 3-5 minutes. Reaction times will vary depending on
climate, dilution, and desired color. Do not let the patina dry on the surface.
3. Rinse the metal with water to stop the reaction. Buff the surface with a microfiber towel or soft sponge just
hard enough to remove any film left by the patina. Pat dry with clean white paper towels.
4. Reapply the patina and repeat the rinsing process as needed for a darker or more uniform finish.
5. Before using a sealer, heat the surface with a torch or heat gun to evaporate any excess water in the metal.
Apply a sealer such a Clear Guard or Ever Clear to protect the finish.
