This is an original staircase in German Village getting sanded down with the Festool. The staircase leads from the first floor to the second floor. We wanted to blend the blonde hardwood on the first floor with the dark hardwood on the second floor. We decided to sand off the the old finish, but not deep enough to remove the character marks from 100 years of use. We actually highlighted the character marks with a dark stain before applying multiple coats of a water based polyurethane. We also gave the risers a facelift.
