To its credit, the material is 5/8" thick--an old world floor.
I was even thinking about sanding it down and using a clear urethane auto finish or a clear epoxy.
I think you would gain nothing from sanding it. You would have more of the same after a little use.
In addition I wasn't aware that automotive finishes were suitable for foot traffic but I could be wrong.
The epoxy might be a way to go but have never heard of that either. If any of the floor sees daily sunshine the epoxy will turn yellow over time.
