ARDEX K15-HB is an advanced and versatile high build levelling compound designed for applications from 5mm up to a maximum of 35mm. It is virtually tension free and is designed to rapidly level uneven, hard sub-floors.
Used in conjunction with either ARDEX P 82, ARDEX P51 or ARDEX P 4 primers, ARDEX K15-HB can be applied to old sub-floors, e.g. concrete and other hard and rigid bases. ARDEX K15-HB is a grey powder consisting of special cements, graded aggregates and high quality synthetic resins.
When mixed with water, a fluid, pumpable mortar is produced which can be applied to the required thickness in one operation. For thicknesses greater than 20mm it is possible to incorporate larger ARDEX Coarse Aggregate in the mixed mortar, thus giving significant cost savings for greater application thicknesses.
When applied at 20°C ARDEX K15-HB can normally be walked on after approximately 2 hours. The applied product dries and hardens rapidly so that even thick applications are ready to receive resilient floor finishes such as PVC within 24 hours. Ceramic floor tiles can be installed on top of ARDEX K15-HB as soon as the surface of the ARDEX K15-HB has attained sufficient strength and hardness.
