Mechanical vs. Topical Polished Concrete, How to Polish

The Topical Process. The opposite side of this discussion is a topical concrete polish. The method is relatively the same as the mechanically polished floor, but the course of action is shorter and it leaves the floor at less than maximum refinement. Most of the time the topically processed progression ends at 200- or 400-grit step.
