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."
