Polished Concrete is mechanically treated concrete, treated with diamond grinding tools. Typically polished concrete is defined as treated with 800 grit up to 3000 grit level, (anything around below 400 grit is not technically considered polishing). Grinding tools are progressive pads building to the desired polish level. Polishing often includes using liquid hardeners and/or densifiers to add durability and serviceability to the surface. Colors and dyes can be used in conjunction with the polished system to further enhance the aesthetics. Some other methods to meet client desires for a polished concrete look depend on the existing concrete profile.
