Can I re-coat my floor instead of re-sanding?
If your floor has not been waxed or oiled, re-coating is a great option. It takes less time, is significantly less expensive than re-sanding and creates less of a mess.
The new aluminum oxide finishes last for about a generation before any major re-coating or refinishing is required unless the floors have been abused.
If you re-coat your floors every few years, before the finish has worn through, you will prolong the life of the surface of your floor and reduce the need for re-sanding.
