One of the most sought after interior floors for residential and commercial is polished concrete.
This explanation from ppc imaginarium does an excellent job explaining the process. Concrete polishing can also be applied to self leveling concrete. Self leveling cement overlays have evolved during the past few years. They smooth out uneven surfaces or use as an underlayment for tile, hardwood and carpet.
One the most intriguing aspects of concrete is its finish – it can be rough and raw or smooth and polished. Polished concrete results can differ depending on the level of polishing.
The process of polishing concrete is not dissimilar from sanding wood. Diamond-impregnated disks vary in fineness to progressively grind down the surface of the concrete. Various levels of shine and smoothness can are available.
Preparing to polish concrete requires removing existing coatings using the correct tools. Coarse grinding blades start at 16 to 20-grit for tough surfaces.
Disks of varying grits may are used achieve the desired result. A high polish finishes uses up to a grit of 1500 or finer to achieve a glossy finish.
For smaller areas near walls, use hand sanders with polishing pads. Like sand paper, the pads vary in fineness and are ideal for working on smaller areas.
