High compressive strength with maximum resistance to wheel tracking and indentations — sturdy enough to double as a commercial wear topping in warehouse and industrial applications where a flat, smooth concrete surface matters.\u003c\/p\u003e\n\u003cp\u003eUse it for leveling, smoothing, and repairing interior residential or commercial floors before installing flooring systems or coverings, fast-track resurfacing and construction of horizontal wear surfaces, and over radiant-heated floors (or to encapsulate hydronic\/electric radiant heat systems).\u003c\/p\u003e\n\u003cp\u003eMeets compression and flatness requirements of ASTM F710 and ASTM F2873.
