ARDEX K 15MICROTEC® is a special cement blend. When mixed with water, it becomes a liquid compound which when spread above 2 – 3mm produces a smooth flat surface. ARDEX K 15MICROTEC® hardens quickly and achieves high early strength. It will not shrink or spall, even when applied in thick layers. Formulated with high flow properties, ARDEX K 15MICROTEC® remains fluid even for applications requiring 3mm or less to provide a durable, flat, smooth floor finish.
