Only the German texts apply.PRODUCT DESCRIPTION Ardaflex S2 Premium is an extremely highly flexible, one-component, very low-emission and wise Dunnbettmortel with strong initial adhesion and almost unlimited application possibilities. The use of light fillers results in higher flat performances than with conventional Dunnbettmorteln and light and supple processing properties. Ardaflex S2 Premium is fast hardening After approx. 5 to 6 hours ceramic tiles and slabs as well as colour-sensitive natural stones can be grouted The bonded adhesive mortar is permanently resistant to frost and has a high deformability Ardaflex S2 Premium is tested according to DIN EN 12004-C2 FTE and DIN EN 12002- S2 and therefore exceeds the requirements of the guideline "Flexmortel" in terms of minimum formability by more than twice Ardaflex S2 Premium is very low emission according to GEV-Emicode EC1R and low chromate according to EU-VO 1907/2006 The glue is white . Ardaflex S2 Premium is suitable for bonding ceramic wall and floor tiles, in particular porcelain stoneware, glass and porcelain mosaics to interior and exterior surfaces as well as to underwater areas. Ardaflex S2 Premium is also suitable for laying natural and concrete stone slabs as well as translucent, colour-sensitive and calibrated types of natural stone, the most common types of marble and hard foam slabs. The use of Ardaflex S2 Premium is particularly recommended for laying on substrates with a surface critical for adhesion, e.g. exposed concrete, mastic asphalt and calcium sulphate-bonded screeds, on old interior tile coverings, gypsum plaster and gypsum building boards on subfloors where considerable long changes are to be expected due to large temperature differences such as rain, sun, frost and snow, e.g. on screeds with underfloor heating or on balcony, terrace and façade surfaces on precast concrete parts and in-situ concrete, where dry shrinkage is to be expected until complete drying out in outdoor and underwater areas in combination with Bostik Ardatec composite waterproofing, e.g. in swimming pools MARBLE TILLING WITH ARDAFLEX S2 PREMIUM Calibrated marble slabs, also of light and translucent types, can be laid with Ardaflex S2 Premium Substrates must be solid, dry and free from impurities or separating agents. For highly absorbent surfaces, Ardagrip Classic must be used as a primer for gypsum-bound substrates. Suitable substrates for Ardaflex S2 Premium are e.g: Concrete, lightweight and porous concrete, cement, lime and gypsum plasters, gypsum construction boards, gypsum plasterboard and gypsum fibre boards, cement, gusasphalt and calcium sulphate-bound screeds, gypsum-bound dry screed boards and old tile coverings. Non-absorbent and smooth surfaces in the interior can be primed with Ardagrip Special or Ardagrip Xpress, in the exterior with Ardagrip Xpress. Alternatively, a thin layer of Ardaflex S2 Premium can be applied as a contact layer. Calcium sulphate-bound screeds must be sanded, dusted, sufficiently dry and primed Residual moisture content Residual moisture content < 0.5% CM. Heated screeds must be heated up and down in accordance with standards (heating protocol). Residual moisture: Cement screeds: < 2.0% CM; calcium sulphate-bonded screeds < 0.3% CM. Decoupling with ARDAL tile insulation boards is necessary for laying on chipboards. The relevant standards, guidelines, ZDB bulletin boards and the general rules of technology apply. JUNGE ZEMENTESTRICHEMITEMITWith Ardaflex S2 Premium ceramic tiles and slabs can be laid on unheated "young" cement screeds of the minimum quality class CT-F4 according to DIN 13888. The screed is ready for laying from the time when the cement screed can be walked on until a maximum of 5 days after screed completion. UNDER-gROUNDING THE TILE ON TILE Due to the high ductility of Ardaflex S2 Premium, no primer is required when laying on old tile coverings. A thin layer of adhesive is sufficient as a contact layer. PROCESSING Ardaflex S2 Premium should not be used at temperatures below + 5 °C. The DIN 18157 part 1, execution of ceramic linings in the thin bed procedure, is to be considered. Expansion joints in the ceramic covering must be arranged to the required extent with Bostik Sanitä rsilicon Profi, Bostik Marmorsilicon or Bostik Unterwassersilicon. ANMISCHENArdaflex S2 Premium is mixed with tap water in a clean vessel, free from lumps. For 20 kg powder, add approx. 5.2 l water to the mixing vessel. A furniture mixer is recommended for mixing. After a ripening time of approx. 3 minutes, the adhesive mortar is briefly stirred again and can then be processed immediately. The mixed material can be processed for approx. 1 hour. Apply AdhesiveSArdaflex S2 Premium with the smooth side of an application trowel in a thin layer onto the substrate. Finally, new furniture is applied to the fresh contact layer and brushed off with a toothed strip corresponding to the tile format. Only as much surface with furniture may be preferred that the clothing materials can still be pushed into the fresh adhesive bed. The laying time (open time) is at least 30 minutes, depending on the ambient and substrate conditions. It is important to ensure that the ceramic cladding materials are bonded over their entire surface and free of blowholes, both on the outside and in the underwater area. This may require relocation using the buttering-floating method. PUTTING After approx. 5 to 6 hours, the installed floor covering is walkable and can be grouted with the appropriate ARDAL grouting tools. The full load is given after approx. 7 days. WORK PROTECTION Cement, reacts alkaline with water. Eye and skin irritations are possible. Please observe the hazard information and safety advice on the containers and in the safety data sheets. StorageCool and dry. Minimum shelf life 6 months.
