Place the bronze piece on a workspace designated for painting. Lay out a drop cloth around the bronze. Use some light-grit sandpaper to lightly sand the surface of your bronze structure.
Apply a coat of latex primer to the surface of the bronze piece. Allow a few hours for the primer to dry. The dry time varies depending on your specific primer manufacturer. Refer to the label instructions for specific dry times.
Use a soft-bristled paint brush to apply a coat of latex bronze paint. The latex paint should match the color of the original bronze glaze. Let the coat of paint dry completely, according to the label instructions.
Use light-grit sandpaper to sound out any lumps in the paint after it has dried. Apply a second coat, let it dry and sand the paint again. Repeat this until you get the desired bronze look.
