Kitchen cabinets that are not made of solid wood are usually made of some form of laminate, which is a plastic or vinyl covering that goes over a plywood or composite base. One of the advantages of laminate is that it allows for a wide range of different decorating choices. On the downside, it can look warn and dingy over time. You can revitalise laminate cabinets without peeling off the old laminate, as long as they're firmly affixed to the frame and in good shape. See your local home improvement store for the right type of laminate for this project.
Use a screwdriver to take apart the cabinets, removing the hinges and knobs.
Dull all the surfaces to be re-laminated by running a vibrating sander over the cabinets.
Measure out the dimensions of one of the spans you're working on (the door front, for example, or one of the edges of the cabinet body). Transfer those measurements to a piece of laminate, marking them out with a pencil and adding about an inch all around, so the cutout piece will be slightly bigger than the space it will cover.
Use a razor knife to cut out the laminate along the lines.
Peel the paper off the back of the cut piece of laminate. Carefully press the laminate onto the surface, leaving an overhang of about an inch all around.
Cut away the overhanging laminate by running your razor knife along the cabinet's edges. Push your laminate roller over the surface to make it flat and secure.
Repeat the process for each section of the cabinets. Reassemble the cabinets after all the parts are laminated.
