Concrete grinders use rotating discs embedded with small diamond particles in a resin or metal matrix. Rotating horizontally, these discs polish and smooth the floor surface.
In addition to abrasion levels, bond hardness, shapes, and diamond concentrations, the diamond tooling discs are available for a wide range of functions.
For example, coarse grit abrasives can be used to dislodge stains, grease, paint, and other coatings, level uneven areas or joints, and add light texturing, while finer grit abrasives are used for a glossy, smooth, polished finish.
Polishing indoor floors often involve concrete grinding. Polishing concrete is the process of running increasingly finer diamond tools over it to produce a high-sheen finish. Many different methods are available for polishing concrete.
