This finish is industrial; which is more aimed for extensive zones as parking lots, garages, vehicles entrances at family houses; with a pore covering matte finish to make easier its cleaning. It is one of the most resistant finishes in the concrete, it is fabricated with the right machinery and a product made off corundum (one of the toughest stones found in nature), a rolling layer is added which can resist for years to heavy machinery friction without deteriorating its support. I can be made in every color, even gray is the most common though.
