Are Concrete Treatments necessary? A common misconception regarding concrete is that it is hard, therefore it should last forever. Far from the truth, especially regarding the surface of the concrete, which can dust and wear under what appears to be the mildest form of traffic-the shoes on our feet. A simple, economic solution is the application of a liquid hardener/densifier treatment. It’s long-lasting and, with simple maintenance, can improve the sheen with increased traffic. Need to enhance the surface sheen sooner? This can be accomplished through and economical burnishing technique on the concrete surface. Want a high shine? Then polish the floor as if you were polishing marble or granite.
