To complete the slab-style cabinet doors, begin with a good sanding.
Install a coarse grit sanding pad onto your random orbital sander and sand the entire cabinet door, paying special attention to the tongue and groove joints. When satisfied with the coarse sanding, move to a finer grit and sand the entire cabinet door again. Repeat this process until you have completed your sanding with a very fine grit, at least 320. You may even wish to spend a few minutes hand sanding for a perfect finish.
Remove all sawdust from your cabinet doors, and then begin to apply the finish of your choice, whether paint or stain followed by a few coats of polyurethane, or another finish of your choosing.
When the finish has dried, install the doors by attaching them to the hinges of your choice, and add your chosen handles (if any).
