Application

For leveling and smoothing most types of sub-floors including concrete, cement screeds, tiles and anhydrite screeds. Ideal for use with ARDEX flooring adhesives.

Description

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


Features and benefits:

  • Improved yield and superior flow and levelling characteristics.
  • Rapid hardening - walk on after two 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.


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.

Height

ARDEX K 15 can be applied from a very thin coating up to 35mm thick. ARDEX K 15 should be applied at thicknesses greater than 1.5mm to benefit from its self-levelling properties.


NOTE: Non-absorbent sub-floors, e.g. surface damp proof membranes, must be levelled with at least 3mm of the smoothing compound up to a maximum of 6mm thick.

Material

Special cements, graded aggregates and high quality synthetic resins.

Primer

All surfaces must be primed.

Not required.

P51 primer.

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.

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 including ARDEX DPM/ ARDEX DPM 1C/ ARDEX DPM 1CR.

P4 primer.

Solvent free rapid drying primer, applied to concrete, screeds, terrazzo and ceramic tiles and can be used externally.

Aggregate filler

Not required.

ARDEX 3—8 mm Coarse Aggregate.

Application thickness

0—35 mm.

Coverage

Approximately 1.4 kg of ARDEX K 15 per m² per mm thick.

e.g. One 22 kg bag will give enough material to cover approx. 5.25 m² at 3 mm thick.

Compressive strength – 28 days

35 N/mm².

Flexural strength

9.0 N/mm².
