Description
Ardex S28 Tile Adhesive is a rapid hardening and rapid drying tile adhesive with specific properties for fixing moisture sensitive natural stone floor tiles, as well as porcelain, mosaics, fully vitrified and ceramic tiles, in internal dry locations.
Ardex S28 Tile Adhesive is available in white only, in 20kg bags.
Ardex S28 Tile Adhesive has a unique semi-pourable consistency ideal for fixing large format floor tiles. It incorporates ARDEX Rapidry Technology – meaning that the mix water is totally bound into the hardened adhesive which virtually eliminates the risk of water staining of moisture sensitive natural stone tiles, or the mix water affecting wooden substrates.
Ardex S28 White is ideally suited to fixing translucent stones and natural stone where a light coloured background bed may be required. The designation C2 FTE S1, in accordance with BS EN 12004, classifies Ardex S28 as ‘improved fast setting cementitious adhesive with reduced slip and extended open time.’
The additional characteristics of Ardex S28 Tile Adhesive, determined in accordance with the test standards listed in BS EN 12004 are a tensile adhesion strength of greater than 1 N/mm2 adhesion value. The mixed mortar has an extended open time of up to 30 minutes, and an easily workable, semi-pourable consistency to facilitate the solid bed fixing of large format floor tiles.
Ardex S28 Tile Adhesive adheres strongly to most construction materials such as concrete, cement and sand screeds, heated sub-floors, anhydrite screeds, and existing ceramic tiled surfaces.
Coverage:
A 20kg bag will yield approximately 18.1 litres of mortar, using approximately 1.1kg of powder per m² per mm thickness of adhesive bed. The actual coverage achieved in practice will depend on the back profile of the tile, notched trowel and technique used to bed the tiles e.g. a 20kg bag will cover approximately 6m² at 3mm thickness.
Technical Data:
Weight of fresh mortar approximately 1.4kg/litre
Working time (20°C) approximately 45-60 minutes
Adjusting time (20°C) approximately 15 minutes
