Description

ARDEX K 11 is a rapid hardening, levelling and smoothing compound designed for new, clean, prepared and primed sub-floors such as cement screeds, gypsum screeds and concrete.


Features and benefits:

  • Receives floorcoverings the next day.
  • Rapid hardening - walkable in 150 minutes.
  • Free flowing mortar 1.5–10 mm.
  • Can be applied by trowel or pump.
  • Low odour and high yield.


Thickness:

The mixed mortar can be applied up to a maximum thickness of 10 mm in one application but will still retain its free-flowing properties at a thickness of only 2 mm to provide excellent coverage and material economy.

  • Limitations: ARDEX K11 is limited to 10 mm. This is reduced to 6 mm on ARDEX P 4 or ARDEX P 82 primers when applied to ARDEX DPM/ ARDEX DPM 1C/ ARDEX DPM 1CR.

Manufacturer guidance

ARDEX K 11 can be applied from 1.5mm up to a maximum of 10mm in a single application. To utilise its free-flowing properties the minimum application thickness should be greater than 2mm.


A minimum thickness of 3mm should be used on a non-absorbent subfloor where an absorbent layer is required by the flooring adhesive.
