Application

Will level internal sub-floors of concrete, or cement/sand, screeds. Applications include:

  • Levelling tamped, uneven, damaged or rained-on in-situ concrete sub-floors.
  • Adjusting tolerances or camber problems between floors, slabs or pre-cast concrete.
  • Pre-levelling old sub-floors and screeds in renovation projects.

Description

A pumpable sub-floor smoothing compound. When mixed with water, a fluid, pumpable mortar is produced which can be applied to the required thickness in one operation. It is especially useful where the installation time of the floor finish must be kept to a minimum.


Features and benefits:

  • Can normally be walked on and ready to receive ceramic floor tiles after four hours at 20°C.
  • When laying thin, vinyl type floorcoverings, a final smoothing application of ARDEX K 15 will be required, following priming using ARDEX P 51.
  • Direct to ground sub-floors require a suitable ARDEX damp proof membrane.


Thickness:

  • 5–35 mm.
  • Should be applied at thicknesses greater than 5 mm to benefit from its levelling properties.
  • When applying ARDEX K 15-HB at thicknesses over 20 mm, aggregate may be incorporated.


Limitations:

  • When applying K 15-HB to dense, impervious surfaces, e.g. quarry tiles, primed with ARDEX P82 primer, the thickness of K 15-HB should not exceed 10 mm.
  • Not to be used on ARDEX DPM/ ARDEX DPM 1C/ ARDEX DPM 1CR if the levelling compound exceeds 6 mm.
  • All surfaces must be primed.

P82 primer.

Two-part water based synthetic dispersion primer and bonding agent used to form a priming/ bonding layer on most substrates, particularly smooth or dense surfaces, e.g. smooth power floated concrete.
