ARDEX External Wall Tiling System

The ARDEX External Wall Tiling System is suitable for liking to concrete, cement render, brickwork, or blockwork walls. ARDEX X 77 is a high performance, fibre reinforced, polymer modified wall and floor tile adhesive, which has been specially formulated with Microtec Technology to give exceptional properties of adhesion.

ARDEX X 77 is a high performance, fibre reinforced, polymer modified wall and floor tile adhesive. It has been specially formulated with Microtec Technology which greatly improves the adhesion strength, plus increases the ability of the mortar to be more capable of withstanding stress and shear strain, meaning increased security in the tiling system. When mixed with water, an extremely smooth, creamy mortar is produced with superior slump resistance and double extended open time.
