Polished concrete is concrete that has been processed through a series of
mechanically ground “polishing/grinding” steps similar to the production of terrazzo. This process also includes the use of a penetrant chemical known as a hardener. The concrete densifier/hardener penetrates into the concrete and creates a chemical reaction to help harden and dust proof the surface. During concrete polishing the surface is processed through a series of steps (in general a minimum of 6 grinding steps of processing is considered polished concrete) utilizing progressively finer grinding tools. The grinding tools are progressive grits of industrial diamonds in a bonded material such as metal/hybrid/resin often referred to as diamond polishing pads.
