Description:

ARDEX X 78S and ARDEX X 78WS are grey or white MICROTEC fibre reinforced, ultra rapid setting cement- based floor tile adhesives which can be walked on and grouted after only 90 minutes. Specifically formulated to have enhanced properties of adhesion and flexibility, their unique semi-pourable consistency makes them ideal for fixing large format floor tiles.

Features:

• MICROTEC fibre reinforced for high performance
• Semi-pourable consistency ideal for solid bed fixing large format floor tiles
• Ultra rapid setting and hardening – walk on and grout after only 90 minutes
• Ideal for all tile types including porcelain, fully vitrified, mosaics and terrazzo
• High yield
• Suitable for floors with underfloor heating
• Ideal for swimming pools and wet areas
• For internal and external applications

Use:

• ARDEX X 78 S 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 for ARDEX X 78 S and ARDEX X 78 W S classifies the adhesives as ‘improved deformable fast setting cementitious adhesive with extended open time’.
• The additional characteristics for ARDEX X 78 S and ARDEX X 78 W S determined in accordance with BS EN 12004 are 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 X 78 S and ARDEX X 78 W S 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 X 78 S and ARDEX X 78 W S adhere strongly to most construction materials such as concrete, cement and sand screeds, heated sub-floors, anhydrite screeds, and existing ceramic tiled surfaces.
