Unscrew all hardware and hinges from the cabinets.
Press a piece of 80-grit sandpaper onto the bottom of an electric sander. Run the sander along the surface of the cabinets. Repeat with 200-grit and 300-grit sandpaper. Wipe off the cabinets with a tack cloth to remove the dust.
Fill a plastic bag with 30 to 40 long screws. Twist the opening of the plastic bag shut, and repeatedly strike the exterior of the cabinets with the bag, creating dents, nicks and scratches.
Dip a foam brush in crackle finish. Coat the cabinets with a light coat of finish, applying the finish in the direction of the grain. Allow two to four hours of drying time.
Dip a nylon brush in oil-based black paint. Paint the cabinets with a light coat of black, applying the paint in the opposite direction of the grain. As the paint dries, it will begin to separate into a crackle finish.
