ARDEX K 15-HB Hi Build Smoothing Compound
Description

ARDEX K 15-HB is a pumpable sub-floor smoothing compound. It is used to rapidly level internal uneven, hard sub-floors, e.g. concrete or cement:sand screeds. When mixed with water, a fluid, pumpable mortar is produced which can be applied to the required thickness in one operation.

ARDEX K 15-HB can normally be walked on and ready to receive ceramic floor tiles after 4 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. ARDEX K 15-HB 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.

Product Options

Primer:

All surfaces must be primed.

– ARDEX P51:

  • Aqueous synthetic based dispersion primer and bonding agent used to prepare internal surfaces to receive cement-based levelling compounds, adhesives or screeds. Use ARDEX P51 on very absorbent surfaces.

– ARDEX P82:

  • 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.

Aggregate filler:

For thicknesses over 20 mm aggregate may be added.
