Ardex AF200 Plus Uncoupling Matting Adhesive

Description Ardex AF200 Plus Uncoupling Matting Adhesive is a ready mixed adhesive ideal for installing fleece-backed uncoupling mats prior to tiling. Available in either 14 kg or 6 kg tubs. Ardex AF200 Plus has excellent grab and an exceptionally long tack time, with very good early and long term adhesive bond strength, allowing matting systems to be installed in as little as 5 minutes or up to an hour after application. Once the matting has been installed, tiling can commence immediately. Ardex AF200 Plus Uncoupling Matting Adhesive is used to fix fleece-backed uncoupling matting to timber, concrete and cement/sand screed subfloors prior to tiling, and is suitable for use over normal underfloor heating systems. It meets the requirement guidelines for the EMICODE licence ‘EC1 PLUS’, achieving the lowest possible emission limits. Ardex AF200 Plus is recommended for use with uncoupling membranes such as Schluter Ditra Matting and Dural Durabase CI Matting. It is also suitable for use with ThermoSphere Underfloor Heating Membrane, Schluter DITRA HEAT and DITRA HEAT DUO Underfloor Heating Mattings. Surface Preparation: Ensure adequate ventilation. Where required, uneven subfloors can be levelled with the appropriate Ardex Latex or Water-Based Levelling and Smoothing Compound e.g. Arditex NA. Priming is not usually required, however, on highly absorbent surfaces it can be advantageous to prime with Ardex P51 Priming and Bonding Agent diluted 1:3 with cold, clean water. This will maintain the open time of Ardex AF200 Plus Uncoupling Matting Adhesive, and ensure maximum coverage of the adhesive. Timber floor constructions should be load bearing, clean, dry and free of dust and other contaminants. Chipboard floors should be free of wax type waterproofing layers, fire retardants etc. and any other barriers to adhesion. Any repairs such as re-fixing and replacing loose/damaged boards should be carried out before applying Ardex AF200 Plus. When applying Ardex AF200 Plus onto concrete or cement/sand screeds, it is essential that the subfloor is dry i.e. the moisture content is no greater than 75% RH and contains a functioning damp proof membrane. Where an effective damp proof membrane is absent, or the relative humidity of the subfloor is above 75% RH, contact Ardex Technical Services for further information. NOTE FOR CALCIUM SULPHATE BASED SCREEDS: Calcium sulphate screeds (anhydrite and hemihydrate screeds) should be dry, with the moisture content below 0.5% before the uncoupling matting is applied. The screed surface is normally abraded to remove any weak and friable surface material, e.g. by belt sanding or similar, before the matting is installed. Contact the screed supplier for detailed instructions. The dry, prepared surface should be primed with Ardex P51 (diluted 1:3 with clean water), applied with a broom and allowed to dry. Ardex AF200 Plus can then be applied but should be allowed to become tacky to improve drying prior to fixing the matting. Dependent on the information from the gypsum screed manufacturer, a suitably sand blinded coat of an epoxy primer such as Ardex R3E may be required. The uncoupling matting should then be fixed with an Ardex Cement-Based Tile Adhesive. Mixing: Ardex AF200 Plus Uncoupling Matting Adhesive is ready for use, but for optimum performance the adhesive should be thoroughly mixed to ensure the even dispersion of polymers before application. Application: Dry lay the uncoupling matting prior to adhering it to the subfloor to ensure accuracy of fitting. Apply a ribbed adhesive bed of Ardex AF200 Plus Uncoupling Matting Adhesive to the subfloor using an Ardex B1 2mm V-shaped notched serrated adhesive trowel, and leave to air for 5-10 minutes. The matting must then be laid into the wet/tacky Ardex AF200 Plus fleece-side down, and pressed firmly into place using a steel trowel, abutting all edges. The matting must be installed within the 60 minute open time and can be adjusted and repositioned for up 20 minutes. Tiling can commence immediately. NOTE: The airing time is dependent on the absorbency of the subfloor and site conditions. Higher temperatures will shorten and lower temperatures will lengthen the time. NOTE: If waterproofing properties are required, please refer to the matting manufacturer’s instructions for detailing of the joints between separate sections of the matting. NOTE FOR STEEL SUBFLOORS: The steel should be rigid and abraded to provide a shiny, clean surface. Ardex AF200 Plus can then be applied but should be allowed to become tacky, after approximately 10 minutes, prior to fixing the matting. Once the matting is installed, tiling can commence immediately. Tile Fixing: Floor tiles can be fixed with an Ardex Cement Based Tile Adhesive e.g. Ardex X77 or Ardex X78, and grouted with Ardex Flexible Tile Grout, or Ardex EG18 PLUS Epoxide Tile Grout for areas where chemical resistance and hygienic joints are required. When fixing moisture sensitive natural stone, we recommend the use of Ardex S27, Ardex S28 or Ardex X7001 Tile Adhesives and Ardex MG Tile Grout. NOTE: Arditex NA Ultra Rapid Setting Latex Levelling and Smoothing Compound can be applied direct to the uncoupling matting to create a flat, level surface ideal for tiling, making the subsequent application of the tile adhesive quicker, easier and more cost effective. For more information, consult the ARDEX Ultimate Uncoupling Matting Installation System guide or contact ARDEX Technical Services. Coverage: 6kg of adhesive will fix approximately 19m² of matting, and 14kg will fix approximately 45m². For maximum coverage, use a B1 2mm V-shaped notched serrated adhesive trowel and apply at a 45° angle. NOTE: The actual coverage achieved in practice is affected by the application technique and the texture and absorbency of the subfloor. Priming is not usually required, however, on highly absorbent surfaces it can be advantageous to prime with Ardex P51 Priming and Bonding Agent diluted 1:3 with cold, clean water. This will maintain the open time and ensure maximum coverage of the adhesive. Click here to view this product on the manufacturers website. Product Datasheet
