Natural stone floors, especially in a high-traffic area become dull and lose their shine when sediment and grit start eroding the stone’s crystals. The foot pressure forces the sediment lying on the surface, causing an abrasion and fracturing the delicate crystals of the stone. The only safe and proper way to restore the crystals natural ability to reflect light evenly and provide a brilliant shine is to re-hone and re-polish them by using diamond abrasives, engineered and designed particularly for Granite or Marble works.
