I read your suggestions on how to renew a Hartco wood floor. My floor is 24 years old and am not sure if it's a pattern plus 2000 or 5000. Am I correct in assuming a professional sanding machine will not work for sanding this floor? We would like to do the refinishing ourselves and have 280 sqr ft of hardwood. It would be quite a job to sand it with a belt sander.
