 ARDEX K 301™

 
Exterior Self-Leveling Concrete Topping​​​​​​​​​​​​

​ARDEX K 301™ is a self-leveling Portland cement-based topping and underlayment for fast-track resurfacing and smoothing for exterior and interior applications over concrete, porous tile and certain non-porous surfaces when properly prepared – on, above or below grade. ARDEX K 301 can be sealed to create a concrete wear surface for commercial, light industrial and residential applications, including storage rooms, workshops, parking garages, parking decks, driveways, patios and plazas. It can also be used as an underlayment for finish flooring, as well as on permanently wet areas and under moisture remediation systems such as the ARDEX Moisture Control Systems. Installs from 1/4” to 3/4” in one application, and up to 2” with the addition of appropriate aggregate. Pourable or pumpable when mixed with water. Seeks its own level and produces a smooth, flat, hard surface. Hardens quickly and dries fast without shrinking, cracking or spalling. See Technical Update Below​​
