More of a general question regarding floor staining.
We are removing the carpet to expose and use the hardwood floors. Floor boards are in good condition, and already have a finish. Some old paint splatter, which will be easy enough to remove. Plan is to fill in holes from nail punch and then restain.
All floor boards have a consistent colour. The one exception is the floorboards of the hallway, which seem to be a very dark colour. We will sand and finish, but my general question is, whether this stark contrast in finishing is something people have come across before.
