Description Ardex X7001 Tile Adhesive is a MICROTEC fibre reinforced rapid hardening and drying, flexible cement-based floor tile adhesive. It is ideal for fixing floor tiles to wood-based sheets and boards and other surfaces. The inclusion of the fibres reduces the possibility of the floor tiles cracking over board joints if movement of the timber occurs. Ardex X7001 Tile Adhesive is grey in colour and supplied in 20kg bags. Bulk discount rates are also available for 50 bags (pallet rate). The BS EN 12004 C2 E classifies the adhesive as an “improved cementitious adhesive with extended open time and additional characteristics.” Ardex X7001 Tile Adhesive has a built-in admix requiring only the addition of water to provide an adhesive with flexibility which is also suitable for fixing fully vitrified tiles, porcelain and natural stones and will allow grouting to commence after only 2 hours. Ardex X7001 Tile Adhesive is a quick drying low alkalinity cement based adhesive and is therefore particularly suited for the fixing of moisture sensitive natural and agglomerated stone tiles. Consult the latest edition of BS 5385-5. It can also be used to adhere certain accoustic matting systems prior to tiling. Recommended for internal use only. Ardex X7001 Tile Adhesive is also suitable for fixing tilebacker boards to wood based sheets and boards. The mixed mortar has a pourable consistency enabling solid bedding of tiles without the need to butter the back profile. Timber Sub-Floor Surface Preparation: Prior to tiling, ensure that new or existing boards are dry, i.e. conditioned to the environment in which they will be used and are rigidly fixed, ventilated beneath and free from barriers to adhesion. Existing tongue and groove floor boards of traditional construction should be screwed or ring nailed down to the joists to provide a rigidly fixed, flat and adequately braced surface. Any existing floor polish, wax, old adhesive etc., should be removed, e.g. by sanding to expose a clean surface prior to tiling. Where suspended sub-floors of undulating tongue and groove floor boards need to be stiffened by overlaying with plywood or flooring grade chipboard, the tongue and groove floor should be pre-smoothed with ARDITEX latex levelling compound or ARDITEX NA, low odour latex levelling compound before overlaying. Plywood and flooring grade chipboard should have the backs and edges sealed e.g. with polyurethane varnish and be at least 15mm thick and screwed or ring nailed down to the joists at 300mm centres or less. The board surface should be clean and free of barriers to adhesion e.g. fire retardents, impregnated wax etc. Some chipboard floor systems require the joints to be glued together and guidance from the manufacturer should be sought. Existing suspended wooden sub-floors of plywood or chipboard should be adequately constructed to provide a rigid base for the ceramic floor tiling. The boards should be at equilibrium moisture content, i.e. the state of dryness it will attain in normal service conditions, at the time it is covered. In all cases, the wood surface to be tiled should be stable and adequately strong and suitably rigid to withstand the imposed loads without deflection. Extra noggins may be required between the joists to stiffen the floor as advised in BS 5385-3:2007 clause 6.3.4. Ceramic floor tiles should not be used on wood based boards in wet areas, or external locations. If the existing wood floor is damp because of location, e.g. bathroom or kitchen, then the floor must be oversheeted with an appropriate waterproof tile backing or matting system. Floating or heated timber floors are not recommended as bases for rigid floor finishes. Priming: The prepared board surface must be primed with ARDEX P51 primer. The primer should be applied undiluted by brush in one coat only and allowed to dry for at least 1 hour at 20°C. Mixing: ARDEX X7001 powder is added to clean water in a clean container whilst stirring and mixed thoroughly to give a fluid, easily worked mortar. The use of an ARDEX mixing paddle with a 10mm chuck, variable speed electric drill makes light work of mixing. The mixing proportions by volume are approximately 3 1/2 parts ARDEX X7001 to 1 part water. A 20kg bag of ARDEX X7001 requires approximately 4.5 litres of water. The mortar is immediately ready for use and has a pot life of approximately 1 hour at 200C. ARDEX X7001 should be applied at temperatures above 50C. Fixing Technique: The mixed mortar is applied onto the prepared sub-floor and combed through with the appropriate notched trowel to give straight ribs of mortar. The workability of the ARDEX X7001 allows the floor tiles to be fixed in a single operation so that no voids are left beneath the tiles. ARDEX X7001 Tile Adhesive is classified as having an extended open time of not less than 30 minutes when measured in accordance with BS EN 12004. For optimum performance under typical UK site conditions tiles should be fixed within 15 minutes. The area covered by the ribbed mortar bed should be limited so that tiles can be bedded within the open time. When the mixed mortar begins to stiffen the mortar must be discarded, do not add more water. In general, use the following square notch patterns: 5mm x 5mm for flat backed tiles, 8mm x 8mm for general floor tiling or 10mm x 10mm for keyed extruded tiles. The size of notched trowel can be altered depending on the bed thickness required and the profile on the back of the tile, but solid bedding should always be achieved and checked for, as advised in BS 5385-3 and BS 8000 : Section 11.1. For application onto timber based substrates the adhesive bed thickness achieved using the above notched trowels should be between 1mm and 4mm. The newly laid tiles can be adjusted for up to 15 minutes after fixing. Grouting: Tiles fixed with ARDEX X7001 can be grouted after 2 hours at 20°C with either the ARDEX-FLEX grouts or the appropriate ARDEX grouts incorporating ARDEX E101 admix where necessary e.g.,timber. For guidance on grouting natural stones, please consult the ARDEX Natural Stone Tiling Guide, with reference to using ARDEX MG grout. Higher temperatures will shorten and lower temperatures will lengthen the time taken before grouting may commence. Coverage: A 20kg bag will yield approximately 14.4 litres of mortar, equivalent to approximately 4.8m2 of a solid 3mm bed of adhesive. Approximately 1.4kg of Ardex X7001 powder/m2/mm of bed thickness. Technical Data: Bulk density of powder: approximately 1.3kg/ltr Weight of fresh mortar: approximately 1.7kg/ltr Working time (20C): approximately 1 hour Fixing time: approximately 15 minutes Adjusting time: approximately 15 minutes Product Datasheet Click here to view this product on the manufacturers website.
