My main level floor is original 1964 9" square parquet . . . any guess as to what finish was used ? wax ? was polyurethane around in 1964 ?
So far, in a year, we have not used any cleaner; just vacuuming & Swiffering. We used Bona for spot cleaning even though we don't know the finish.
We suspect the previous owner's housekeeper (sometime in 45 years) used water-based liquids because there is noticeable shrinkage and noise (walking causes the tiles to strike the concrete base or each other). (We didn't detect it as the seller had a lot of area rugs.)
The finish has a slight shine . . . not a noticeable dull which I would expect for a wax.
Any way to test by using different cleaners ??
The house was built by a neighbor builder for his retirement, so his contractors used mostly good materials and presumably didn't skimp on workmanship.
