ARDEX Liquid BackerBoard

Area Floors has Ardex – a full line of tile installation & stone installation products.

Self-Leveling Underlayment for Interior Wood and Concrete Subfloors

Save time, money and hassle with ARDEX Liquid BackerBoard. No more cutting, remeasuring, gluing, screwing, taping…..not to mention saving the wear and tear on your back and knees from kneeling, getting up and down off the floor, and carrying those bulky hard backer board sheets. Liquid BackerBoard is easier to ship, store and there is no waste due to damaged backer board sheets.

An industry first high-performance Portland cement-based self-leveling underlayment for use over interior wood and concrete subfloors for the installation of tile and stone floors….and it does NOT require lath mesh or additives.
ARDEX Liquid BackerBoard replaces traditional bulky, time consuming and expensive hard backer board by providing a flatter, smoother and more durable surface….and provides a more efficient and less expensive installation overall.

It’s simple, just prime the substrate with ARDEX P-51™, mix the ARDEX Liquid BackerBoard with water and pour for a smooth, flat and durable surface. Perfect for tile and stone installations and provides the ultimate surface for the installation of large format tile. You’re walking on it in 2 to 3 hours and laying tile flooring in just 6 hours!

The ARDEX Liquid BackerBoard’s pristine smooth and flat surface cannot be achieved with traditional hard, inflexible backer board sheets. It eliminates uneven wobbling and cracking of large format tiles, and the need for additional back-buttering to compensate for the dips and uneven surfaces of backer board sheets.
