Remove the knobs from the cabinets with a screwdriver.
Mix a solution of 1 part ammonia to 1 part water. Drop the knob hardware into the solution. Scrub each piece of hardware with a toothbrush to remove all the grease from the surface of the metal. Rinse each piece in clean water. Lay the hardware on a towel to dry.
Sand each knob with fine-grit sandpaper. Sanding will help the paint and primer adhere to the slick surface of the ceramic. Wipe away all sanding dust.
Place a piece of cardboard outside on the grass or driveway. Set the knobs on a large piece of cardboard so that the front of the knob is facing up. Spray primer and paint will create noxious fumes and are best used outdoors.
Spray the cabinet knobs with bonding spray primer. The can should indicate that it is a bonding primer. Spray in a steady back-and-forth motion. Let the knobs dry completely.
Paint the knobs with spray paint. Use a steady back-and-forth motion. Allow the paint to dry. Add more coats of paint as necessary to completely cover the knobs.
Add decorative elements. Use a small artist's brush and enamel paint. Use your creativity to add patterns, designs and drawings to your cabinet knobs. Allow the paint to dry.
