Over time, copper garden statuary acquires a patina. It looks green with hints of bronze or black. The statue's copper has oxidised because of exposure to the elements. As a result, a lovely greenish cast, called verdigris, develops. The Statue of Liberty is a prime example of this natural process. Designers created a faux finish process to mimic nature's ageing process without the need to begin with copper. If you'd like to recreate this patina on a brand-new concrete statue, you can do so easily using latex paints and sea sponges.
Lay down a dust sheet, and place the statue on it.
Pour the black, green and copper paints into the paint trays.
Dip a flat paintbrush into the black paint, remove the excess paint on the tray's treads, and paint the statue. Let the base coat dry for 1 hour.
Dip a sea sponge into the medium green paint, and dab once on a paper towel to remove any globs.
Dab the sponge over the statue, beginning at the bottom and working toward the top on an angle. Reapply the paint to the sponge as necessary. Cover 90 per cent of the statute, leaving a tiny amount of the black base coat showing. Let the paint dry for 1 hour.
Dip a clean sea sponge into the light green paint, and dab once on a paper towel to remove any globs.
Dab the sponge over the statue, working up and at an angle as before. Press lightly, and let a good portion of the medium green colour show through. The lightest green is just a highlight. Go back over any sections that are too light with the medium green. Let the paint dry for 1 hour.
Dip a sea sponge into the copper paint, and dab once on a paper towel to remove any globs.
Dab the sponge over the statue judiciously, giving just a hint of copper colour on the statue. Let the paint dry for 1 hour.
Dip a paintbrush into the sealer, and apply it to the statute to seal the piece and protect the faux finish. Let the coat dry for 2 hours and apply another if desired.
Work in a well-ventilated area to avoid overexposure to paint fumes.
