ARDEX K40 HB is a fibre reinforced, high build levelling and smoothing compound designed for applications from 3mm up to a maximum of 40mm. K 40 HB hardens rapidly and can be walked on in as little as 2 hours, regardless of thickness, which means there’s minimal disruption on live sites, particularly those that are constantly in use by the customer or other trades.

Ardex K40 HB has almost double the working time of competitor products, which means trowel marks drop out with ease, joins between mixes can be easily spiked up to 35 minutes after application, and there’s little or no additional preparation before fitting!

Applications up to 5mm can receive resilient floorcoverings, including timber, after 6 hours, and thicker applications up to 40mm after 48 hours. Ceramic floor tiles can be fixed 2 hours after application.


ARDEX K 40 HB will level and smooth, in a single application, most new and existing internal subfloors including concrete, cement/sand
screeds, anhydrite screeds, stone, terrazzo and ceramic tiles, and suitable timber floors. Other applications include levelling uneven, damaged or rain damaged in-situ concrete subfloors, and adjusting tolerances or camber problems between floors, slabs, or pre-cast concrete.
