ARDEX E 90 is a special synthetic dispersion for use with ARDEX X 7 G, ARDEX X 7 Wand ARDEX S 21 cementbased 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 X7G or X7W/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 S21/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 S21/ARDEX E 90 mortar may also be used for applications to existing smooth impervious surfaces.
