I’m currently moving into my brothers old room, and the floor needs to be repaired and sealed before i can place a wood floor of my choice over it.
Since it’s such an old house the boards run long ways, and a few are broken at the ends, and he smoked so the wood in the floor smells. How can I repair the floor and seal all the smell of smoke, so I can place the new flooring over it with out any problems in the future?
