Re-sanding a floor: When we re-sand (or refinish) a wood floor, we bring in large sanding machines that strip all of the old finish and stain off the floor, exposing a layer of new wood. This new layer can then be stained (if desired) and finished with anywhere from 2 to 5 coats, depending on the potential wear and the type of finish used.
With this process, we sand the entire finish off the floor, and then rebuild the finish surface. This procedure can take up to five days or longer, depending upon the size of the space.
Re-coating a floor: When we recoat a floor, we use a light, low speed sander that only lightly scuffs the top layer of finish. This scuffing or abrasion aids in the adhesion of the new finish, which is than applied in one or two coats. Typically, the cost of recoating is less than half that of re-sanding.
