Description Ardex E90 Adhesive Admix is a special synthetic dispersion for use with Ardex X7 and Ardex S21 cement-based adhesives. Ardex E90 Adhesive Admix is diluted with an equal volume of water prior to mixing with the adhesive powder. The addition of the product with the adhesive produces a mortar that, once set and hardened, has high adhesive strength, elastic and water repellent properties. Ardex E90 Adhesive Admix is supplied in 3.6 kg containers. 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 E90 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 E90 mortar is ideal for bedding large flat backed and/or smooth dense tiles and for providing water repellent bedding where required. ARDEX S21/Ardex E90 mortar may also be used for applications to existing smooth impervious surfaces. Mixing: In a clean container dilute the Ardex E90 Adhesive Admix with an equal volume of clean water. Add the ARDEX adhesive powder to the diluted Ardex E90 whilst stirring thoroughly until an easily worked mortar is obtained. The viscosity and slump resistance of the mortar can be adjusted by slightly increasing, or reducing the amount of water to suit site conditions and the materials being fixed. Material Requirement: 3.6kg of Ardex E 90 when diluted with an equal volume of water is sufficient for a 20kg bag of adhesive. 2kg of Ardex E 90 is sufficient for a 22kg bag of Ardex S21. Application: The mixed mortar is applied in the same way as the normal ARDEX adhesive mortar when fixing ceramic tiles, mosaics, etc. For more information consult the relevant ARDEX product data sheet.
