We recently refinished our red oak hardwood floors using a drum sander. I'm not happy with the results. There are a few gouging marks (not deep) which we didn't notice til after with added the water based polyurethane finish.
Is it possible to resand the floor with a orbital sander and get good results or our my floors permanently damaged?
Is an orbital, rotary and disk sander the same thing? If not, what do you recommend?
