Premium Microtec Tile Adhesive


  • Reduced effect of shear strain and stress on tiling systems
  • Microtec Technology improves adhesive strength
  • Water & frost resistant
  • 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.

    ARDEX X 77  is especially suited to high-performance situations with heavy pedestrian traffic e.g. shopping centres. ARDEX X 77 accommodates shrinkage movement associated with early age concrete and screeds. It can be used over concrete that is at least 7 days old and screeds and renders after 16 hours. ARDEX X 77 is efflorescence free due to the addition of special additives.
