Resurfacing brings worn and unsightly floors back to their original
beauty. Resurfacing is much more extensive than recoating, and the
techniques are ideal for hardwood floors that are already dull and
scratched. First, machine sanding removes the old finish and exposes
new wood. After sanding, the floor can be stained if you desire a
specific color. Finally, to protect the floor, either a surface finish
or a penetrating seal and wax are applied.
