I do a lot of refinishing. With your cabinets, you MAY be able to get buy with a light sand and then stain/poly. This will only work if your faces are decent (not grease-stained, dinged, etc.) There is a product that combines stain with polyurethane. (Minwax makes a great variety.) If your cabinets are in good shape, just sand them lightly to increase adhesion of the new poly. Then, you can layer on your product. It takes a while to dry, so make sure you remove your doors/drawers so they can lay flat. Work in quick, thin coats for the remaining cabinetry stuck to the wall to ensure a smooth and even finish. The more layers you add, the darker the color will be. Use a fine steel wool to smooth the finish between coats (after it dries). Then, use a tack-cloth (available at hardware stores) to remove any dust and residue.
