Floors have been sanded 2-3 times

Q: I live in an old house which had oak floors sanded (they are light beige now), apparently a few times. I have cracks and areas in the kitchen where the color is worn. I cannot afford to put in new floors. I was wondering if it is possible to fix the cracks and stains (from carpet, plants and my dog’s urine) and, sand old floor, and refinish (the kitchen).

A: If the floors have been sanded 2-3 times, they won’t tolerate another one. I would suggest living with them as they are until you can afford to replace them. Otherwise, you are just throwing good money after bad.
