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.
