Now that I know there is such a thing, please tell, how can you tell? I just recently inherited the family home, and the first thing I did was rip up the carpet. The floor looked great under, but as time goes on with 2 kids and 2 dogs, it is wearing down faster than I imagined. I'd like to do something to protect it, and slow down the wear and tear. I've read these few messages, and decided not to do it myself. Thank you for that. But I'd like to know how to tell if a floor is beyong refinishing. Thanks alot!
