Remove any knobs and handles from the cabinet. Apply a base coat of green satin latex to the cabinet exterior (if you wish, you can go back later and use one of the wall colors on the interior). Let dry. (Don't worry if the color seems too bright -- the glaze will tone it down.)
Once the glaze has dried completely, sand lightly with 100-grit sandpaper, working in the same direction as the brushstrokes. This will help to blend any lines. The more pressure you apply, the more glaze you will pull up. You may also wish to sand edges a little more in order to create the appearance of wear. Wipe the surface to remove any dust from the sanding.
Use cotton rags to apply wood wax to the entire painted surface. This will blend the lines and impart a slight sheen to the piece. When the wax is dry, buff the cabinet.
Thin the black acrylic paint with a small amount of water. Dip the end of a flat brush in the mixture and blot on paper towels or rags to remove most of it. Use the handle of an artist's brush to flick the bristles of the larger brush, splattering tiny drops on black on the cabinet. After the paint is dry, replace the hardware, either with the original pieces or with new ones that coordinate with your new kitchen.
