Unscrew the hardware from your oak cabinet, and set the hardware aside.
Attach the sandpaper to the sander, and gently sand the oak cabinet to remove any finishes. Sand the oak until it’s dull and chalky looking.
Use the brush attachment to vacuum up any sawdust from the oak cabinet.
Apply the primer to the entire oak cabinet with a paintbrush. Allow the primer to dry for 48 hours. Repeat the process one to two more times. If the oak is still grainy, you can sand it again after you apply the primer. If you sand again, remember to add an extra coat of primer afterward.
Paint the cabinet with latex paint. Allow the cabinet to dry for 2 to 3 days between each coat of paint. Apply two to three coats of paint until you get the color you desire.
