Keraquick Easy S1 is a rapid-setting, high-performance, S1 flexible cementitious adhesive designed for installing ceramic, porcelain, and moisture-stable natural stone tiles and mosaics on floors. It is classified as a Cementitious (C) Improved (2), Fast Setting (F), and Deformable (S1) adhesive (C2F S1), ensuring strong adhesion and flexibility. Suitable for both interior and exterior applications, it can be used on cement-based and calcium sulphate screeds, concrete, plywood-overlaid floors, existing unglazed ceramic tiles, and tile backer boards.
Key Points:
- High Performance & Fast Setting: Ensures quick installation with strong adhesion.
- Flexible & Deformable (S1): Adapts to surface movement, reducing the risk of cracks.
- Versatile Application: Suitable for ceramic, porcelain, and natural stone tiles.
- Interior & Exterior Use: Compatible with various substrates, including screeds, concrete, plywood, and tile backer boards.
Storage: Up to 12 months when kept off the ground in its original, unopened packaging and protected from high humidity.

Keraquick Easy S1 is ideal for interior and exterior installations of ceramic, porcelain, and moisture-stable natural stone tiles and mosaics on cement-based and properly prepared calcium sulphate screeds, concrete, plywood-overlaid floors, existing unglazed ceramic tiles, and tile backer boards.
Application Examples:
- High-Traffic Areas: Ideal for rapid renovations in public buildings, motorway services, pedestrian walkways, supermarkets, showrooms, and airports.
- Special Environments: Suitable for swimming pools, industrial plants (breweries, wine cellars, dairies), and refrigeration units.
- Wet Areas & Outdoor Spaces: Perfect for quick installations in bathrooms, showers, kitchens, conservatories, balconies, and terraces.
- Underfloor Heating & Large Tiles: Works effectively with underfloor heating systems, undertile heating cables, and large-format tiles due to excellent wetting-out properties.
- Cold Weather Installations: Suitable for external tiling in autumn/winter when temperatures drop below +5ºC.
Preparation of the Substrate:
Ensure substrates are dry, level, mechanically strong, and free from contaminants like grease, oil, old adhesives, and bitumen residues. Damp substrates may extend the setting time of Keraquick Easy S1. Cementitious substrates must be fully cured before tiling—concrete should be at least 6 weeks old, and cement-based screeds at least 3 weeks unless produced with special MAPEI binders (Mapecem, Topcem) or pre-blended screeds (Mapecem Pronto, Topcem Pronto). Power-floated concrete should be mechanically abraded to open the surface and remove curing agents. Heated screeds must be commissioned per BS 5385 regulations before tiling. Calcium sulphate screeds must have a moisture content of 0.5% w/w, with all surface laitance removed and dust vacuumed before priming with Eco Prim T Plus (1:2 with water) or Primer G (neat). Plywood floors must be a minimum of 15mm thick, exterior-grade (Class 3 per EN 314 & EN 636), and securely fixed at 300mm centers.
Mixing:
Pour 4.2-4.6 litres of clean water into a bucket, then gradually add a 20kg bag of Keraquick Easy S1 while mechanically mixing until a smooth, lump-free paste forms. Allow to stand for 2 minutes, then briefly stir again. Use within 30 minutes.
Application:
Apply the adhesive with a notched trowel up to 10mm thick. First, skim-coat the substrate with the flat edge of the trowel, then comb through with the notched edge. Use an appropriate notch size for tile dimensions, aiming for full coverage. For demanding applications (exterior tiling in freezing conditions, swimming pools, high-traffic areas, tiles with deep recesses, or large-format tiles), back-butter the tiles to enhance adhesion. Highly absorbent internal surfaces should be primed with Primer G or Eco Prim T Plus before tiling.
Installing the Tiles:
Do not wet tiles before installation, but if the backs are dusty, briefly dip them in clean water and allow them to dry. Keraquick Easy S1 has an open time of 15-20 minutes under normal conditions, but high temperatures, wind, or absorbent substrates can reduce this significantly. Always check for a surface skin. If one forms, remove the adhesive and reapply fresh material. Do not add water to rework skinned adhesive, as this will compromise adhesion. Protect newly installed tiles from rain or washout for at least 3 hours and from frost or strong sun for 24 hours.
Limitations – Do Not Use Keraquick Easy S1:
- On metals, rubber, cork, PVC sheets, or linoleum.
- For bonding expanded polystyrene panels with a protective film/vapor barrier.
- For bonding glass or agglomerated tiles and mosaics.
