Q: We have a few small stains on our hardwood floor. They are either from water or from paint. Can we sand and recoat just those small spots, or would we have to do the whole floor?
A: You can try the less intrusive approach first, and just try to re do the spots. Better chance of getting a good blend if you try to finish entire boards, rather than simply part of a board, in which case you will no doubt see a lap line.
