Ardex SD-T B Pre-Levelling Base Mix

Ardex SD-T B Pre-Levelling Base Mix. Ardex K80 Industrial Floor System provides the ideal combination of toughness, low maintenance, ease of application and high durability coupled with the incorporation of the unique Ardex ‘Rapidry Formula’. Due to the ‘Rapidry Formula’ chemically binding the mixed water, the Ardex K80 literally dries within itself at the same time as it rapidly develops strength.

When mixed with water, Ardex K80 produces a fluid self-levelling mortar which can be applied by trowel or pump as a floor finish from 5mm-10mm. Where thick applications are required the cost effective Ardex SD-TB base mix can be applied from 10mm-50mm depth to level the concrete base. The ‘Rapidry Formula’ technology of the Ardex SD-TB base mix means that within only hours of its application a minimum 5mm thickness of Ardex K80 can be applied.

Ardex K80 Industrial Floor System is virtually tension free and provides a very high strength surface which has enough resiliency to accept heavy wheeled traffic, such as that found in industrial factories, workshops and warehouses, etc. Independent testing at Aston University has confirmed the excellent inherent abrasion resistance of Ardex K80/SD-TB Industrial Floor System ensuring its suitability for a wide range of applications.
