These hallways always cause trouble. The humidity, the dirt from outside, and the shoes are causing so many troubles for the flooring that every house owner has to repair the hallway once per 3-5 years, especially if it's a house for rent.
We did super sanding for a low budget because the owner has a specific amount for this service. After that, we did the special edition of finishing to seal the surface much better.
The job took 10 hours.
