Can This Hardwood Floor Be Saved?
I sanded a similar wood floor, a bit older though.
I used a drum sander 8 or 10” in diameter and 14 or 16” long roughly.
I sanded diagonal to the grain with coarse then finer grades of paper. It took about 5 passes in total with 2 at the medium paper.
This produced a lot of dust and I sealed all the doors to prevent other rooms getting covered. Also had a big vac to get the dust.
Stain and finish as preferred.
