How long will sanding take?


An average-sized room (Living room or hallway for instance) should take a day to sand and apply 3 coats of varnish. You  will also need to factor in additional time to let the varnish fully cure (harden), during which time the floor should not be walked on with shoes for 72 hours.  Ideally, all furniture will not return to the room until varnish has fully cured.
