Polishing concrete is very similar to sanding wood. Polished Concrete Services has heavy duty polishing machines equipped with changeable, progressively finer grits of diamond impregnated segments or disks (like sandpaper). These diamond disks are used to gradually grind down surfaces to your desired degree of shine and smoothness.

The process begins with the use of coarse diamond segments bonded in a metallic matrix. These segments are coarse enough to remove minor pits, blemishes, stains, or light coatings from the floor in preparation for final smoothing. Depending on the condition of the concrete, this initial rough grinding is generally a three or four step process.

The next steps involve fine grinding of the concrete surface using diamond abrasives embedded in a plastic or resin matrix. Polished Concrete Services will use finer grits of polishing disks (a process called lapping) until the floor has the desired sheen. For an extremely high-gloss finish, a final grit of 3000 or finer may be used. Our experienced polishing crews know when to switch to the next grit by observing the floor surface and the amount of material being removed.

During the final polishing step, Polished Concrete Services will spread a commercial polishing compound onto the surface to give the floor a bit more sheen. These compounds also help clean any residue remaining on the surface from the polishing process and leave a dirt-resistant finish.
