ARDEX TL 1000™ is a self-leveling underlayment formulated with a blend of Portland cement, other hydraulic cements and polymers. ARDEX TL 1000 is designed specifically for fast leveling of interior concrete, cementitious terrazzo or ceramic, quarry or porcelain tiles prior to installing flooring – on, above or below grade. It can even be installed over concrete treated with certain curing compounds (see below). Pourable or pumpable when mixed with water, ARDEX TL 1000 seeks its own level and produces a durable, smooth and flat floor surface with minimum labor.
