Concrete polishing has certainly become a rising trend within the commercial and residential building sector. Its popularity is due to the face that polished concrete mimics high quality stone with high shine and extremely low maintenance. More importantly, polished concrete is an environmentally responsible system that lends itself to LEED projects.

Although concrete grinders play a major role in producing these polished floors, it is really the diamond tooling that becomes most significant. However, with so many different tooling options out there, how and what do you choose?

Three Types of diamond tooling

 Currently on the market, there are three different types of tooling: metals, hybrids, and resins. These range from the most aggressive to the least aggressive.  But before determining which tooling to get, it is imperative to figure out how hard or soft the concrete is. That will decide which tooling best suits the concrete at hand.

There are three factors that determine a metal tooling: bond type, number of segments, and number of grits.

Bonds: The bond type refers to the matrix that the small diamond chips are held by. In other words, how strong the small diamond chips are held together. When working on hard concrete, for example, it is suggested to use a soft or extra soft bond metal because it exposes more of the diamond chips against the hard concrete.

Segments: The number of segments determines how much head pressure is on the segments. Thus, the more segments on the mounting plate mean less pressure because the weight is more evenly distributed. Metals most commonly come in one or two segments.

Grits: The grit refers to the size of the diamonds within the metal. The diamond sizes become smaller and finer as the girt number increases.   

Hybrids diamonds are a cross between metals and resin diamonds. They are more aggressive than resins and leave fewer scratches on the concrete compared to metals. With hybrids, it is only necessary to determine which grit is suitable for the concrete. They are available in grit sizes 30, 50, 100, 200, and 400.

Similar to hybrids, it is only necessary to determine the grit type for resins. These pads are made to create high quality shine on the concrete floors. They are available in grit sizes 30, 50, 100, 200, 400, 800, 1500, and 3000.

With more knowledge under your belt, figuring out the right tooling for the job has been made that much simpler. By working with the right tooling for each concrete floor, it increases productivity, wastes less tooling, and gives more consistent results.
