Pee peels

Q: My dog peed on our floor and we did not notice this until the next day. After cleaning up the mess, I noticed that the finish had lifted and peeled on one side of the wood slat. The wood in not discoloured but you can see where the finished has peeled.

Can I try and apply polyurethane to that one spot or is it better to sand the whole slat and then apply polyurethane to the whole slat of wood?

A: You will likely have better results by doing the entire piece of wood. Make sure it’s dry first.
