The floors in this home are likely original from the 1920's. The lovely owners of the house before me did not care much as it was a rental, and we now have tons of paint and holes on and in the floors.
I'm going to refinish the floors because of the excess of scratches and paint marks. I'd love to be able to fix the holes as well.
From what I understand, the two options are to 1) use wood fill, 2) let poly fill the holes.
What is the best way to make holes such as the ones below look good?
