Here is a squash court that we have refurbished at JAGS sports club in London. We have cleaned and painted all walls, relined the walls, machine floor sanded the floor and remarked the floor with red paint.
In the second picture you can see how dirty the floor was before sanding. You can also see how much of a difference that floor sanding makes to an existing old wooden floor.
