Ardex K 40 HB FAQs

What is Ardex K 40 HB?

Ardex K 40 HB is a rapid Drying, high build, fibre reinforced levelling and smoothing compound.

What can I use Ardex K 40 HB for?

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. Ardex K 40 H can also level uneven, damaged or rain damaged in-situ concrete subfloors, and adjusting tolerances or camber problems between floors, slabs, or pre-cast concrete.

Do I need to use a primer for Ardex K 40 HB?

All surfaces must be primed to maximise the working time, maintain the flow life, and prevent air bubbles rising through the levelling compound. See TDS for which primer to use of which substrate.

How do I mix Ardex K 40 HB?

Use between 3½ and 3¾ litres of water per 22kg bag. Add the powder to the required amount of clean water in a clean mixing container whilst stirring thoroughly until a lump free consistency is produced. The use of an ARDEX mixing paddle with a 10mm chuck slow speed (600-1000 rpm) electric drill makes light work of mixing. Use the minimum amount of water content for thick applications or cold conditions.
