BritFlex Rapid RS further informationCoverage: 3.5Kg/m2 at approximately 3mm bed depth.BRITFLEX RAPIDSET is suitable for fixing different tiles including ceramics, slate, limestone, marble, porcelain, terrazzo and mosaics to a variety of surfaces. Moisture sensitive backgrounds must be sealed correctly before tiling and it is recommended that a suitable wet room system is used. If used externally then a solid bed method of fixing is recommended. BRITFLEX RAPIDSET is suitable for matted underfloor heating, and the heating element should be embedded in a layer of tile adhesive or self levelling compound and allowed to set prior to fixing tiles.PREPARATIONAll surfaces must be free from loose matter, dry, clean from any dust or grease, fixed securely with screws to the supports and be dimensionally stable with no excessive movement. Wooden floors should be pre-strengthened with at least 15mm marine plywood mechanically fixed at 300mm centres.MIXING RATIOAdd 20kg of BRITFLEX RAPIDSET into a mixing vessel containing 5It of clean cold water. BRITFLEX RAPIDSET should be mixed either by hand or with a mechanical mixer with water to form a smooth, lump free thixotropic paste. Mix as desired and allow to stand for 2 minutes before re-mixing for 30 seconds. Apply adhesive to the surface so that a continuous bed of adhesive between 3mm and 6mm is achieved. BRITFLEX RAPIDSET can be used up to 12mm in uneven areas.TECHNICALAll work should be carried out in accordance to the following Codes of Practice:BS 8000: Workmanship on Construction SitesBS 5385: Wall and Floor TilingAPPLICATION TEMPERATURE: Between 5°C and 30°CPOT LIFE: 40 minutesBEFORE GROUTING: 3 hours*FULL USE: 24 hours**NOTE – The above times refer to site conditions of 20 °C. These times will be increased at lower temperatures and reduced at elevated temperatures.BRITFLEX RAPIDSET RS summary technical informationReaction to Fire:FBond Strength as: - early tensile adhesion strength - initial tensile adhesion strength= 0.5N/ mm2= 1.0N/ mm2Durability for: a) - tensile adhesion strength after heat ageing b) - tensile adhesion strength after water immersion c) - tensile adhesion strength after freeze/thaw cycle= 1.0N/ mm2 = 1.0N/ mm2 = 1.0N/ mm2APPLICATIONPlasterboard: Ensure boards are securely fixed to the framework ideally screwed at 300mm centres and are rigid. The weight limit of plasterboard should be adhered to (32kg/m2 maximum load). Prime with a 2:1 dilution of BRITPRIMER and clean cold water before tiling.Gypsum Plaster: Ensure surface is dry and dust free with less than 0.5% moisture. Allow new plaster to dry for a minimum of 4 weeks. Prime with BritPrim Grip which will seal and give a key to the surface (20kg/m2 maximum load).Brickwork, Blockwork and Render: Ensure surface is fully cured and dry prior to tiling. Ensure the surface is free of contaminates. Prime the surface with a 1:1 dilution of BRITPRIMER and clean cold water before tiling.Concrete Screeds: Ensure surface is dry with less than 5% moisture. New concrete screeds must be allowed a minimum of 6 weeks drying time. Mechanically remove laitance from the surface of the concrete. Prime with a 1:1 dilution of BRITPRIMER and clean cold water before tiling. Very porous screeds may require a second coat applied 90° to the first.Asphalt, Vinyl and Glazed Tiles: Ensure surface is stable and suitable to receive a further surface coating, Remove all contaminates. Abrade the surface to provide a key. Prime the surface with BRITPRIMER diluted 1:1 with clean cold water mixed with approx 30% by weight of BRITFLEX RAPIDSET to form a slurry bond coat. Apply to floor and allow to dry before tiling commences.Timber – Tongue & Groove Floorboards: Ensure timber is structurally sound and capable of supporting the weight of the tiles/adhesive. Surface must be free of any contaminates. Boards must be securely fixed to supporting joists prior to overboarding with at least 15mm marine plywood screw fixed at 300mm centres. Apply one neat coat of BRITPRIMER and allow to dry until tacky before tiling.CLEANINGRemove surplus adhesive with a damp cloth. Clean tools with water.GROUTINGGrouting should be carried out using BRITFLEXI GROUT only after 3 hours and depending on site conditions.STORAGEStore unopened in original packaging in cool, dry conditions. BRITFLEX RAPIDSET has a shelf life of 12 months from the date shown on the packaging.
