I had my floors redone about 5 years ago. The floors look in above average

floor over the existing coats, or does the whole thing need to be sanded
down?


No, you can't just simply add another coat or 2, you have to sand it
down first, then sand between coats, otherwise the polyurethane will
not get absorbed by the wood and just sit there and form ripples or
puddles. Do it right, get a pro.
