If you use your Browser's FIND feature, and search the Forum Page for the work hardwood you'll find LOTS of info on refinishing hardwood floors. If you find a post that doesn's suit your needs, don't give up and keep searching the page. IF you end up searching the WHOLE page w/o finding what you want, post up again.
(Please trust me ... There's lots of info on the Forum about the subject.) My best to ya and hope this helps.
