USE TO FIX All types of ceramic tiles and mosaics in internal & external situations, including swimming pools.
GROUTING Can proceed once the tile bed has hardened sufficiently so that the tiles will not be dislodged. When grouting wall tiles the ARDEX X77/ARDEX X 77 W is normally hard enough after 8 hours at 20 degrees C depending on the porosity of the tile and the background. When grouting floor tiles the ARDEX X77/ARDEX X77 W is normally hard enough after 24 hours at 20 degrees C to accept foot traffic depending on the porosity of the tile and the background. Higher temperatures will shorten and lower temperatures will lengthen these times. The tile joints should be grouted with the appropriate ARDEX or ARDEX-FLEX grout mortar.
OPEN TIME 60 minutes
PACK SIZE 22 kg, 11kg or 5 kg bags
COVERAGE A 20 kg bag will yield approximately 19 litres of mortar, using approximately 1 kg of powder per sq m per mm thickness of adhesive bed. The actual coverage achieved in practice will depend on the back profile of the tile and the notched trowel and technique used to bed the tiles e.g. a 20 kg bag of ARDEX X77/ARDEX X77 W will cover approximately 11 sq metres when using a 5 x 5 mmsquare toothed and notched trowel.
HEATING ARDEX X77/ARDEX X77W is suitable for fixing ceramic tiles to concrete or cement and sand screeds with underfloor heating.
STORAGE Ardex X77 contains a reducing agent to control the levelof Chromium VI when mixed prior to use. Ardex 77 must be stored in opened packaging clear of the ground in cool dry conditions and protected from excessive draught. If stored correctly, as detailed above and used within 12 months of the date shown on the packaging, the activity of the reducing agent (added to control the level of Chromium VI) will be maintained and this product will contain, when mixed with water, no more than 0.0002% (2ppm) soluble Chromium VI of the total dry weight of the cement content of this product.
