ARDEX X 77 Flexible Wall and Floor Tile Adhesive

ARDEX X 77 is a cement-based flexible fibre-reinforced adhesive. It has been formulated to allow the fixing of fully vitrified tiles and those with low porosity without the need of an admixture.

The mixed mortar has a slump free consistency with very high initial grab enabling heavy wall tiles to be fixed, thus reducing the need for battens and spacers.

Features and benefits:

• MICROTEC fibre reinforcement for high performance.
• Advanced slump resistance, double that of 'T' classified adhesives, ideal for fixing large format wall tiles.
• Achieves an extended open time of up to 60 minutes, twice the requirement of BS 12004, and double the slump resistance of ‘T’ classified adhesives.
• Three hour pot life.
• High yield – 6.3 m² at 3 mm.
• Suitable for underfloor heating.
• Will adhere strongly to most construction materials although it must be used with ARDEX P 51 Primer when fixing to plaster and ARDEX P 82 when fixing to smooth impervious surfaces including existing ceramic tiling, internal asphalt, terrazzo, sound and well adhered paint coatings and old adhesive residues. ARDEX P 4 - rapid drying primer, applied to concrete, screeds, terrazzo and ceramic tiles and can be used externally.
• The BS EN 12004 C2 TE S1 designation classifies the adhesives as an "improved cementitious adhesives with additional characteristics, reduced slip and extended open time."
