An extreme example of heavy foot traffic and dirt wear and tear, the Boys and Girls Club Gym floor.
We were called in one year after the floor had been refinished with an oil based product, which was not a durable enough finish to handle the heavy foot traffic. We cleaned and buffed the floor to prep it for finish and applied two coats of Bona Traffic finish. About three years later, we were called back to address a plumbing issue. The floor looked terrific and had very little wear compared to the first refinish.
