Hey y'all, I need some advice on my wood flooring, and I'm too lazy to dig through hours of internet research... Any of you guys ever refinish a 1920's wood floor? My house has all wood floors throughout (except the kitchens and baths), and it looks like only 1 has ever been refinished. I want to professionally refinish them all before moving in, but there's no way I can, just not possible. So... I'm thinking I'm going to do it myself. These are shots of the living room, the most important one: Floor 1 Floor 2 Floor 3 Floor 4 I can get a floor sander and a buffer pretty easily, but I don't know the technique, and how to tell when I've sanded enough. The main floor, the one that will make the room if it's exposed, is pretty worn out by the door and a little deformed in some corners. For the final finish, what do y'all recommend? Shellac - Natural, long lasting, good for keeping an "original" look urethane - protective, long lasting, but looks terrible when it finally wears wax - needs to be re-waxed every year or two Any others you guys might know I should consider?
