Pumpable Sub-Floor Smoothing Compound Base Mix  

ARDEX K 15-B is an advanced and versatile base mix designed for applications from 7mm 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 P82 or ARDEX P51 primers, ARDEX K 15-B  can be applied to old sub-floors, e.g. concrete and other hard and rigid bases. 

ARDEX K 15-B 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.
