A sanding paper disk with a grid of 60 that can be attached to a velcro paddrive which could be fitted on a floor scrubbing machine. The sanding disks are used to sand down floors or layers of floors to prepare it for a new layer of treatment to cover the floor. Used oftentimes with wood floors, where the previous sealant should be removed and resealed. The higher the grid number, the finer the sanding paper.
