Newbie homeowner-to-be here. I've been reading through a lot of the wood floor posts but every one I've seen says you have to sand the entire floor to get rid of the old finish before putting in new finish.The house we're buying has really nice, dark wood floors. They appear to be in great condition, but most of the finish has been scuffed off. Would it be a disaster if I just sanded it down (manually, without a machine) to dull the remaining finish and then resealed it with water-based urethane? I am primarily concerned with getting them sealed, and not too worried about color differences or mainly cosmetic issues. There are several smallish rooms so I'd be doing them one by one.
Thanks in advance for any advice





so I'm likely going to have to do this all myself somehow.
