It depends and we need to have a look. However if you have a an average-sized room (bedroom, lounge or hallway for instance) it should take a day to sand and a further day to hand finish and varnish/wax or oil.

If your floor needs repairing then this can add to the time as we might have to wait for filler and replacement wood to be fully fixed in place. You should also factor in time for the varnish, sealant or oil to dry before moving your furniture back in and walking on the floor.
