Things You'll Need
Blue painter's tape
If your cabinets have been shellacked, you'll need to remove the glossy element before you can paint. Shellac is a type of glossy varnish typically applied to wood cabinets. It often adds a yellow or orange cast to the finish. Unlike painted cabinets, the glossiness of shellac does not hold paint well unless you prepare the surface before you apply the paint, requiring extra preparation. You must remove the shellac before applying the paint if you want to keep the paint from flaking off the surface at a later date.
Tape off around your cabinets with blue painter's tape. Cover any surface which might get splattered with paint, like the counter or floor, with plastic sheeting or a tack cloth.

Sand the surface of all the cabinets, doors and drawer fronts with a large grit sandpaper, such as 100-grit silicone carbide sandpaper. Wipe the surface with a damp rag to remove the dust once you've finished sanding. Let the surface of the cabinets dry.
