KERAQUICK S1
Rapid set flexible S1 adhesive, high performance, fast setting, non-slip cementitious adhesive for the installation of ceramic, porcelain and stone tiles and mosaics.

WHERE TO USE
Bonding to cement-based and suitably prepared calcium sulphate based screeds, concrete, plywood overlaid floors existing unglazed ceramic floor tiles, cement-based renders, gypsum plaster, plasterboard, tilebacker boards (Check our Tekwarm Lite Overlay Board).
· 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 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).
· The installation of tiles externally in autumn/winter where night time temperatures drop below +5ºC.

See note below.
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.

RECOMMENDATIONS
Use Keraquick S1 mixed with Latex Plus in the following cases:
· on plywood substrates fixed direct to joists (minimum 18 mm plywood);
· for bonding tiles to tongue and groove floorboards or minimum P5 grade chipboard;
· for bonding tiles to existing glazed / porcelain tiles;
· for bonding tiles to well-bonded existing vinyl floor tiles;
· for bonding directly over underfloor/undertile heating elements.
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.
