About 20 years ago in my last house I did a 15x25 foot 3/4 inch red oak hardwood floor with a 3/4 inch walnut accent strip, then a window pane border. I did the sanding, then had someone else put on the most evil, toxic Swedish finish I could every five years. Held up to 14 years of dogs and kids, though the sun started to fade the walnut accent strip over time. It would darken back up when refinished. I still sneak by the house now and again to make sure the new owners have not carpted it over. Still looks great.
Well worth the artificial knee I now have!
