  • Gluing, screwing and taping
  • Not to mention saving the wear and tear on your back and knees from kneeling, getting up and down off the floor
  • Carrying those bulky hard backer board sheets
  • Liquid BackerBoard is easier to ship and store
  • There is no waste due to damaged backer board sheets

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!

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.
