Start by painting the inside edges and openings of the face frames, then the outer cabinet sides, and finally the face frame fronts. This allows you to work quickly in the less critical areas, and enables you to see and correct any drips or smudges on the most visible areas.
Next, paint the cabinet doors and drawer fronts, along with any separate wood pieces or moldings. If these parts have raised or routed features, be sure to flow the paint into crevices and corners, but don’t allow it to accumulate in these spots.
Always apply paint in thin, light coats, but be sure to cover all areas. Thin coats leave fewer visible brushstrokes and dry more quickly. Don’t lay the finish on thickly and don’t overwork the brush — too many brush strokes will create air bubbles in the finish, leaving bumps and pits when it dries.
Allow the paint to dry for at least four hours between coats. When dry, resand all surfaces lightly to prepare them for the second coat, wipe away all sanding dust with a tack cloth, then repaint. Two coats of quality paint are usually all that is necessary, but you may want to add a third coat because kitchen cabinets take lots of punishment from cooking heat and day-to-day use, and wood surfaces need all the protection they can get.
