  • Superior water resistance

  • Can be laid and can cover old tiles and waterproofing membranes

  • Excellent workability


Packaging: 25 kg

Storage: 12 months from date of manufacture


Surface Preparation

  • All surfaces must be structurally sound, free from movement, dry, clean, free from oil, grease, wax, dust and other contaminants.

  • For painted surfaces;  It should be scraped to bare at least 80% of the original substrate

  • Newly built  concrete must be allowed to cure for 28 days

  • Newly rendered surfaces must be allowed to cure for at least 7 days

  • Old rendered and old concrete surfaces must be thoroughly cleaned prior to tiling.

  • Steel trowel finished concrete must be acid-etched or mechanically abraded prior to tilling.

  • Expansion joints coinciding with joints in the substrate should be incorporated at the design stage at a maximum of 5 meters spacing and must not be tiled over. Movement joints must not be less than 6mm or greater than 100mm wide.



  • Mixing ratio: 5-6 L of clean water : 25 Kg Eurotiles S1 Premium Tile Adhesive

  • Slowly pour the Eurotiles S1 Premium Flexible Tile Adhesive to a pail of clean water. Do not pour water into a pail of tile adhesive since it will be difficult to mix and can cause lumps in the mixture.

  • Use a hand mixer or mechanical mixer (speed at 500rpm) for mixing until a thick creamy consistency is achieved free of lumps.

  • Allow the mixture to stand for 5-10 minutes for chemical slaking and to reduce bubbles.

  • Remix the compound before use

  • Mixed Eurotiles S1 Premium  Flexible Tile Adhesive should be used up within 1-2 hours depending on environment humidity.

  • Avoid pouring additional water or powder after mixing, slaking period or when the tile adhesive has set.



  • Spread evenly the adhesive onto the back of the tile with the notched side of the trowel.

  • When installing tile larger than 30x30 cm and tiles with deep grooves/ridges or uneven back, trowel a double coat of tile adhesive onto the substrate and also spread adhesive at  the back of tiles prior to installation of each tile.

  • Choices of notched trowel depend on the size of the tile, depth knobs, grooves and ridges on the back of the tiles and evenness of the substrate.

  • Avoid spreading more than 1 sqm. of adhesive at  one time. Make sure that the adhesive is wet when the tiles are laid and tapped into the position to create positive contact with the adhesive.

  • Press tiles firmly into position before the adhesive skins, ensuring all tiles are well-bedded and no voids occur. Adjust or move the tiles against the notched trowel line.


Cleaning and Grouting

  • Allow the tilling to set for 24 hours before grouting with Eurotiles Superior Tile Grout. Allow the grouting to slake for 2 hours.

  • Wipe off residue on the tile surface with a wet foam (clean water). Hands and tools can be cleaned with water.
