I have an oak hardwood floor that has damage from water getting under the floor in two small spots. The floor is dried out now (2 weeks with commercial fans, and no buckeling but some dark spots remain from the water that got under the floor. It is only on about 3 boards and I want to sand offf the finish, try to bleach it, match the stain as best I can an recoat the floor. I cannot afford to sand the whole floor down to the bare floor so I plan on light sanding of the entire floor, dust collection, recoat with Bona strong. I hope it will please my wife with a decent look. Can I make the stains look better with my proposed plan or do I have to replace boards? Any direction you can give would be appreciated.
