Why do people use polished concrete floors?
The clients chose polished concrete for a good portion of their interior floors for a variety of reasons, including aesthetics, ease of maintenance, and light reflectivity. Upon visiting some of their earlier polished floors, we noticed a few problems that ultimately had nothing to do with the quality of the work done by the polishing subcontractor, but instead resulted from the work of the placing and finishing contractor. When polished concrete started becoming popular, specifications were being written inappropriately, setting up the polishing contractor for failure. One specification we came across in particular called for a light salt-and-pepper finish (exposing the sands with no coarse-aggregate exposure), but made no reference to floor flatness (F F) or floor levelness (F L) tolerances. As a result, some of these floors exhibited unlevel, wavy surfaces with raised sections that made it nearly impossible to expose only the sands. These areas showed patches of coarse-aggregate exposure, which the owners did not want. The remedy for this problem was to install the concrete within specified tolerances. In addition, specifying lower-shrinkage concrete materials, combined with tighter joint spacing, would significantly reduce the amount curling the concrete would exhibit.
What is the difference between sanding and polishing concrete?
Polishing concrete is very similar to sanding wood. Machines equipped with diamond-segmented abrasives (akin to sandpaper) are used to grind down concrete surfaces to the desired degree of shine and smoothness. As when sanding wood, you gradually progress from coarser-grit to finer-grit abrasives. (In this case, grit is the particle size of the diamond.) The result is a glossy, mirror-like finish.
Why do you use water for polishing diamonds?
Wet polishing uses water to cool the diamond abrasives and eliminate grinding dust. Because the water reduces friction and acts as a lubricant, it increases the life of the polishing abrasives. The chief disadvantage of this method is the cleanup.
