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 direct to joists (minimum 18 mm plywood);
  • 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.

APPLICATION PROCEDURE

Preparing the substrate

Substrates must be dry, flat, mechanically strong, sound, free from loose areas, grease, oil, paint, wax, old flooring adhesive and bitumen residues and any other contamination (e.g. plaster droppings), which may affect the adhesion. Damp substrates may lengthen Keraquick S1’s setting time.

Cementitious substrates must be cured and any shrinkage process must be at an end before tiles are installed. Renders should be cured for at least 2 weeks, concrete at least 6 weeks old, cement- based screeds for at least 3 weeks unless they have been produced using the special MAPEI binders Mapecem or Topcem or with a pre- blended screed mix such as Mapecem Pronto or Topcem Pronto. The substrate surface should ideally be open textured. Powerfloated concrete should be mechanically abraded (scabbled or shot-blasted) to open up the surface and to remove any curing agents.

Heated screeds must be commissioned in accordance with recognised technical regulations and the guidelines given in BS 5385 parts 4 and 5. The commissioning process must be carried out before the installation of tiles or stone finishes.

Gypsum plaster should be at least 4 weeks old and primed with Primer G. Note: over-trowelled plaster surfaces should be lightly abraded to provide a key before priming. Calcium sulphate screeds must be dry to a moisture content of 0.5% w/w when measured using the carbide method. All surface laitance must be removed by mechanical abrasion and all dust thoroughly removed by vacuum. Prime the surface with Eco Prim T (diluted 1:2 with water) or alternatively Primer G.

Plasterboard and tilebacker boards must be installed to provide a firm, stable substrate with no protruding fixings. Plywood must be a minimum of 15 mm thick and screw fixed at maximum 200 mm centres on walls and 300 mm centres on floors. It should be of class 3 in accordance with EN 314 and EN 636.
Steel substrates must be well braced to provide a deflection free support. Remove all rust, mould, oil, grease and other
contamination. Apply a skim / scratch coat of Keraquick S1 mixed with Latex Plus and allow to set, then fix the tiles in a void free bed of the same product.

Preparing the mix

A 20 kg bag of Keraquick S1 grey and white should be mixed with about 4.8-5.2 litres of water. Alternatively mix a 20 kg bag of grey or white with 6 kg of Latex Plus. Where other bag sizes are used, mix at a ratio of 1 kg powder to 0.25 litres of water or 0.3 litres Latex Plus. Pour clean water (or liquid) into a clean mixing bucket. Add Keraquick S1 powder and mechanically stir until a homogenous, lump- free paste is achieved. Allow the mix to stand for 2 minutes then briefly stir again. Use the mix within 30 minutes of preparation.

Applying the mix

Apply the prepared Keraquick S1 to the substrate with a notched trowel to a maximum of 10 mm thick. To achieve good adhesion to the substrate, first apply a skim coat of adhesive over the substrate using the flat edge of the trowel followed by combing through with the notched edge of the trowel to the required thickness. Ensure that a minimum coverage of 65-70% to the back of the tile is achieved in dry wall areas with 100%, as far as possible, in wet walls areas, on floors and in exteriors (walls and floors). Ensure that a trowel with a notch size and profile appropriate to the size of tile is used.
For demanding applications such as exterior tiling subject to freezing, swimming pools or water feature installations, heavy duty areas, floor tiling to be ground in situ, when installing tiles with deep recesses or lugs on the rear and for fixing large format tiles (> 300 x 300 mm), the adhesive should also be applied to the rear of the tile (back buttering).

For the installation of tiles greater than 600 x 600 mm we recommend the addition of Latex Plus to Keraquick S1.
On highly absorbent substrates it is recommended to prime with e.g. Primer G and Eco Prim T before commencing tiling.

Installing the tiles

Do not wet the tiles before installation; if, however, the backs are very dusty, they should be dipped in clean water. Allow to dry before fixing.

Keraquick S1’s open time in normal temperature and humidity is about 15-20 minutes; unfavourable weather conditions (strong sun, drying wind, high temperature), or a highly absorbent substrate may shorten this open time, sometimes quite drastically, to just a few minutes.
Constantly check to see whether the adhesive has formed a surface skin.

Should a surface skin have formed, the adhesive should be removed and fresh material applied.
It is not recommended to wet the adhesive when it has formed a skin because a non- adhesive film will be formed.

Tiling installed with Keraquick S1 must not be subjected to washout or rain for at least 3 hours and must be protected from frost and strong sun for at least 24 hours after installation.

Spot bonding of insulating materials

Spot bonding to sound-deadening or insulating panels should be applied using a float or trowel, the trowel type and size will be determined by the flatness of the surface and the weight of the panels.

In these cases, check the open time and bear in mind that a few spots of adhesive on heavy panels may require temporary shoring which should only be removed once the Keraquick S1 has begun to set.

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 be allowed to cure for a minimum of 7 days.

Swimming pools, basins and water features can be filled after a minimum of 3 days.

Cleaning

Tools should be cleaned with water before the adhesive sets. Floors and walls can be cleaned with a damp cloth. Water should be used only in moderate quantities and after a few hours.

CONSUMPTION
