Basically the mechanically polished concrete or MPC is a more high end finish and is for indoors only. In this process it is the actual concrete itself that shines. There is no topical coating that is applied, and therefore the finish will last you a lifetime if cared for and maintained properly. The grind and seal method is a more cost effective option of getting a similar finish. The process however involves a clear coating to be applied to the top of the concrete which will wear away over time. It can also have a non-slip grip added and can be used both indoors and outdoors. It is very popular now for garages, driveways, shops, restaurants, bars, homes and offices.
With both methods of polished concrete, you are able to choose your level of stone exposure (how much aggregate you want to see coming through the floor), and you can choose the gloss level – matte, semi-gloss or high gloss.
