Remove hardware. If you are only spraying handles or knobs, you can leave the screws in the cabinets so that you don’t misplace them. If spraying hinges, then you need to take the screws out to spray them.
Clean hardware. Use a green Scotchbrite and dish soap and water.
Wipe down with a deglosser. Let handles fully dry.
Set up a spray painting station. Just make sure you are able to fully spray all surfaces of the hardware.
Cover all surfaces of your hardware with a spray bonding primer. Let dry. Put a fresh piece of cardboard down before adding color.
Use spray paint in large sweeping motions. Let first coat fully dry.
Repeat for 3 coats making sure you fully are covering the hardware.
Let your handles and hardware cure as long as possible. We like to let them dry overnight before putting them back on the cabinets.
