ARDEX K 15 Rapid Drying Heavy Duty Self-Levelling Smoothing Compound
Description

K 15 is a rapid drying self-levelling sub-floor smoothing compound.

Features:

  • Improved yield and superior flow and levelling characteristics.
  • Rapid hardening - walk on after 2 hours.
  • Receives floorcoverings the next day, regardless of thickness at 20°C.
  • Apply from feather edge up to 35 mm thick.
  • Can be applied by trowel or pump.
  • Strong - high compressive strength.
  • Suitable for floors with underfloor heating.
  • Ideal for use with ARDEX flooring adhesives.

Thickness:

May generally be applied to any thickness, but non-absorbent sub-floors, e.g. flooring grade asphalt, must be levelled with at least 1.5 mm of ARDEX K15. No more than 6 mm of ARDEX K 15 should be used on top of asphalt.

  • Limitations: ARDEX K 15 is limited to 10 mm thick on ARDEX P 82 primer. This is reduced to 6 mm on ARDEX P 82 when onto ARDEX DPM/ ARDEX DPM 1C/ ARDEX DPM 1CR.

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 including ARDEX DPM/ ARDEX DPM 1C/ ARDEX DPM 1CR.
  • ARDEX P4 - Solvent free rapid drying primer, applied to concrete, screeds, terrazzo and ceramic tiles and can be used externally.

Aggregate filler:

For thicknesses over 10 mm incorporate up to an equal volume of 3 mm single sized chippings. For thicknesses of 20–35 mm up to an equal volume of 3–8 mm aggregate may be added.
