Ardex X77 & X77 W Flexible Standard Tile Adhesive

ARDEX X 77 and ARDEX X 77 W are advanced, fibre-reinforced, cement-based adhesives available in grey and white. Designed for both floor and wall applications, these MICROTEC products offer exceptional adhesion and flexibility, with an extended open time of up to 60 minutes, double the industry requirement. Their superior slump resistance makes them ideal for fixing large format wall tiles.

1. Versatility: ARDEX X 77 is perfect for fixing various tile types, including ceramic, fully vitrified tiles, glass mosaics, porcelain, and terrazzo, particularly those with low porosity.
2. Performance Standards: Certified under BS EN 12004 C2 TE S1, ARDEX X 77 and ARDEX X 77 W exceed the standards for cementitious adhesives with improved properties like reduced slip and prolonged open time.
3. Slump-Free and Strong Hold: The mixed mortar’s slump-free consistency provides high initial grab, making it ideal for heavy wall tiles, eliminating the need for battens or spacers.
4. Wide Range of Substrates: These adhesives bond strongly to a variety of materials including concrete, heated sub-floors, gypsum plaster, plasterboard, and even primed existing tiles, making them suitable for internal and external use, including swimming pools.

In summary, ARDEX X 77 and ARDEX X 77 W offer superior performance in demanding tile installations, delivering enhanced flexibility, exceptional hold, and versatility across a wide range of surfaces.

Coverage: A 20kg bag of ARDEX X 77 or ARDEX X 77 W will produce about 19 litres of adhesive mortar. To apply a 1mm thick layer of adhesive, you’ll use around 1.05kg of powder per square metre. Actual coverage will depend on factors like the tile’s surface, the type of notched trowel used, and the application method. For example, with an 8mm x 8mm square notched trowel, one 20kg bag can cover up to 8 square metres.

Storage and Shelf Life: ARDEX X 77 and ARDEX X 77 W contain a special agent to control the level of Chromium VI in the adhesive when mixed. To ensure the product remains effective, store it in unopened bags in a cool, dry place, off the ground, and away from strong drafts. When stored correctly, it has a shelf life of 12 months from the date on the packaging. During this time, the reducing agent will ensure that when mixed, the product contains no more than 0.0002% (2ppm) of soluble Chromium VI. Do not use ARDEX X 77 or ARDEX X 77 W after the stated expiration date.
