Rapid set flexible S1 adhesive, high performance, fast setting, non-slip cementittious adhesive for the installation of ceramic, porcelain and stone tiles and mosaics CLASSIFICATION IN COMPLIANCE WITH EN 12004 Keraquick S1 is an improved (2) fast setting (F) cementitious (C) adhesive and slip resistant (T) and deformable (S1) classified as C2FT S1. Conformity of Keraquick S1 is declared in ITT certificates no. 25070276/Gi (TUM) and no. 25080063/Gi (TUM) issued by the Technische Universität München laboratory (Germany). WHERE TO USE Bonding to cement-based and calcium sulphate based screeds, concrete, plywood overlay, existing unglazed ceramic floor tiles, cement-based renders, gypsum plaster, plasterboard, tilebacker boards. • For interior and exterior use. • For the installation of ceramic and porcelain tiles and mosaics. For natural stone not sensitive to moisture. • Suitable for the installation of glass tiles and mosaics. Mix with Latex Plus where the glass has a coating on the rear. • For the installation of insulating materials such as expanded and extruded polystyrene panels, gypsum boards, glass and rockwool, Eraclit®, aerated concrete blocks, sound deadening panels. Some application examples • Renovation in heavily trafficked areas and where surfaces need to be quickly back in service, such as public buildings, motorway services, pedestrian walkways, supermarkets, showrooms, airports etc. • Rapid installation or renovation in swimming pools, industrial plants (breweries, wine cellars, dairies etc.), refrigeration units. • Rapid installation in bathrooms, showers, kitchens, conservatories and on balconies and terraces. • The installation of tiles externally in autumn/winter where night time temperatures drop below +5ºC. See note below. • The installation of tiled finishes to underfloor and undertile heating systems. • The installation of non-absorbent floor tiles over existing floors, where a standard setting adhesive would be too slow. • The installation of natural stone materials including light coloured stone (use Keraquick S1 white for the latter). • The installation of MAPEI Mapetex anti-fracture membrane (when fixed with Keraquick S1 mixed with Latex Plus). Note: When fixing tiles at lower temperatures the pot life and setting time may be extended beyond 2 hours. In autumn / winter temperatures only fix tiles when the substrate and ambient temperature is above +5ºC. When fixing externally ensure that the adhesive is applied during the warmest part of the day and that it will have cured sufficiently before temperatures drop below +5ºC. Protect exposed tiled areas from frost by covering with appropriate materials. TECHNICAL CHARACTERISTICS Keraquick S1 is a grey or white powder composed of a blend of special cements, selectively graded aggregates, synthetic resins and accelerators, which develop high bond strength 2-3 hours after mixing. These properties allow floors and walls tiled using Keraquick S1 to be grouted after only 2 hours. Floors can also be subjected to light foot traffic after 2 hours and full service conditions after 24 hours. Where floors are to be subjected to heavy duty use, such as cherry pickers, the floor tiling should have been allowed to cure for a minimum of 7 days. Mixing Latex Plus with Keraquick S1 improves the deformability to meet the requirements of class S2 (highly deformable) in accordance with EN 12004. RECOMMENDATIONS Use Keraquick S1 mixed with Latex Plus in the following cases: • on plywood substrates fixed dire

• for bonding tiles to tongue and groove floorboards or chipboard; • for bonding tiles to existing glazed / porcelain tiles; • for bonding tiles to well-bonded existing vinyl floor tiles; • for bonding tiles to steel substrates. Do not use Keraquick S1 in the following cases: • on metals (except steel), rubber, cork, PVC sheet and linoleum; • for bonding expanded polystyrene insulation panels with a protective film / vapour barrier.

GROUTING AND SEALING Joints between the tiles can be grouted after a minimum of 2 hours with a suitable MAPEI cementitious or epoxy resin grout, available in a wide range of colours. Movement joints must be sealed with an appropriate elastic sealant such as Mapesil AC, Mapesil LM or Mapeflex PU30. LIGHT FOOT TRAFFIC Floors are able to take light foot traffic after 2-3 hours. Lower temperatures may extend the setting time. READY FOR USE Tiled finishes are ready for use after a minimum of 24 hours. Where floors are to be subjected to heavy loads such as cherry pickers, then the adhesive should...
