ARDEX S 21 Properties




ARDEX S 21 is a special rapid hardening, pourable bedding mortar for floor tiles in internal and external locations. It is especially suitable for fixing large tiles, ceramic and brick pavers, terrazzo tiles and natural stones. Tiles bedded in ARDEX S 21 can be grouted and subjected to loads 3 hours after fixing at normal temperatures. It is particularly suitable for use in situations where the tiling has to be grouted and put into use shortly after bedding, or where low temperatures would unduly extend the setting time of normal cement-based adhesives.ARDEX S 21 is a grey powder based on special cements, high quality synthetic resins and fillers,which is mixed with water to produce an easily applied mortar.ARDEX S 21 contains a reducing agent to control the level of Chromium VI when mixed prior to use.
