A vivid verdigris tone can cover any paintable surface, thanks to a two-part paint application. The base paint contains copper bits, so any item can have this rich look. And oxidizer turns the paint the color of patinated copper.
Apply The Copper Surfacer
Mix the copper surfacer well to ensure that the metal particles are evenly distributed. Apply a thin coat using one of the foam brushes. Let dry (about an hour) before applying a second coat. Repeat until the surface has an even coverage of copper.
Apply The Patina Solution
While the final coat is still tacky, use the second foam brush to apply the blue patina solution, making sure to wear protective gloves. Use liberally for a more overall blue color or sparingly for a more nuanced blue patina.
Add More Solution
The color will start to change within 10 to 15 minutes. Add more solution for a greater color change; if the surfacer is no longer tacky, brush a new coat on the parts you'd like to color, and reapply the solution.
Add More Surfacer
Once dry, you can add more surfacer with a sponge brush if a less overall blue look is desired.
Apply a Sealer
For outdoor use, coat with a sealer, which will halt further oxidation of the surfacer.
