What Does Grit Mean For Concrete Grinding?

So What Does Grit Mean In The Concrete Grinding Industry?

One critical factor in achieving a successful concrete grinding job is choosing the right diamond grit size. Diamond grit size refers to the size of the diamond particles embedded in the grinding tools. It plays a crucial role in determining the efficiency, speed, and quality of the grinding process.

The final piece of the puzzle is GRIT. Grit is generally the easiest component of the disc/plug to understand. Grit is used as a reference to describe the finishing qualities of the diamond disc/plug. The lower the number, the larger the piece of diamond (coarser grit). The higher the number, the smaller the piece of diamond (finer grit). Just like sandpaper, as the grit becomes smaller the finish becomes smoother. Generally in concrete grinding, 30 or 40 grit is about the coarsest required (Usually, 60-80 grit discs/plugs are used in the process of concrete polishing and not concrete grinding)

(Low Grit Number) – Are for faster prep work and for removal of coatings.

(High Grit Number) – Are for smoothing, polishing, and final touch-ups.

Most diamonds are #16 grit – Which is very aggressive for cleaning up concrete slabs.

But they go all the way up to #3,000 grit – Which is for very fine polishing of concrete slabs.

You will mostly use #16 & #30 grit – For removal and prep work on concrete, anything above that is heading towards polishing the concrete slab.
