Description
Ardex X78S Tile Adhesive is a MICROTEC fibre reinforced, ultra rapid setting cement based floor tile adhesive which can be walked on and grouted after only 90 minutes. Specifically formulated to have enhanced properties of adhesion and flexibility, the unique semi-pourable consistency makes it ideal for fixing large format floor tiles.
Ardex X78S Tile Adhesive is available in grey or white, in 20kg bags.
Ardex X78S Tile Adhesive is ideal for fixing fully vitrified or porcelain tiles, and other tiles with low porosity, as well as glass and porcelain mosaics and terrazzo. The BS EN 12004 C2 FE S1 designation classifies the adhesives as ‘improved deformable fast setting cementitious adhesive with extended open time’.
The additional characteristics for Ardex X78S Tile Adhesive determined in accordance with BS EN 12004 is a tensile adhesion strength of greater than 1 N/mm2 adhesion value, greater than 1 N/mm2 after water immersion, greater than 1 N/mm2 after heat aging and greater than 1 N/mm2 after freeze thaw cycling, making this product suitable for internal and external situations, including swimming pools.
The enhanced setting and hardening performance of Ardex X78S Tile Adhesive means that after only 6 hours, the adhesive has already achieved the EN 12004 requirement of 0.5N/mm². The mixed mortar has an easily workable, semi-pourable consistency to facilitate large format floor tile fixing. Ardex X78S Tile Adhesive adheres strongly to most construction materials such as concrete, cement and sand screeds, heated sub-floors, anhydrite screeds, and existing ceramic tiled surfaces.
Coverage:
A 20kg bag of Ardex X78S will yield approximately 16.5 litres of of mortar, using approximately 1.2kg of powder per m² per mm thickness of adhesive bed. The actual coverage achieved in practice will depend on the back profile of the tile and notched trowel and technique used to bed the tiles e.g. a 20kg bag will cover approximately 9.4m² when using a 5mm x 5mm square toothed and notched trowel.
