Tile Adhesive Improver
ARDEX E 90 is a special synthetic dispersion for use with ARDEX X 7 G, ARDEX X 7 W, ARDEX S 16, ARDEX S 16 Wand ARDEX S 21 cement-based adhesives. ARDEX E 90 is diluted with an equal volume of water prior to mixing with the ARDEX adhesive powder. The addition
of ARDEX E 90 produces a mortar that, once set and hardened, has high adhesive strength, elastic and water repellent properties.
The mixed mortar has the same properties as the normally mixed ARDEX adhesive mortar; workability, slump resistance, high initial grab, open time, etc. The substrate preparation follows the recommendations given for the ARDEX adhesives, except that glazed surfaces do not require priming, though they must be clean and free of barrier materials. The improved mortar is especially effective in the following situations:- Fixing large flat-backed tiles and slabs as well as smooth backed, dense and impervious ceramics, vitreous mosaics, etc.
Direct fixing of ceramic tiles onto existing glazed surfaces.
ARDEX X 7 G or X 7 W/ARDEX E 90 mortar can be used for internal or external applications and is useful to inhibit the formation of lime bloom and efflorescence on external tiling.
ARDEX S 16/ARDEX E 90 mortar is particularly useful in internal situations where rapid drying is important; such as fixing to plywood, following priming with ARDEX P 82, and other moisture sensitive backgrounds, and when fixing
to existing smooth impervious surfaces where early walkability is required.
ARDEX S 16 W/ARDEX E 90 mortar has the additional advantage of its white colour combined with its rapid setting and drying properties when fixing translucent marble, tiles and glass mosaics in internal situations.
ARDEX S 21/ARDEX E 90 mortar is ideal for bedding large flat backed and/or smooth dense tiles and for providing water repellent bedding where required. ARDEX S 21/ARDEX E 90 mortar may also be used for applications to existing smooth impervious surfaces.
