Application Information
Instructions for use

Surface treatment

All surfaces should be sound, clean & uncontaminated. This preparation should leave an exposed concrete surface free from dust, loose particles, deletrious matter, oil, grease, chemical films & other contaminant.
All loose particles of mortar, paint, etc. must be physically removed.

Concrete or blockwork: should be allowed to cure sufficiently so that all shrinkage movements take place before fixing tiles.
Gypsum supports: must be treated with PRIMER A16. Should not have a percentage of humidity more than 10%.
The surface of substrates must be moistened slightly with clean water to reduce the absorption of water from the mortar. Do not moistened the tiles.

Place 5.0 – 5.5 liters of cold, potable water (or ELASTOKOL as needed) in the mixing bucket and add slowly 25 kg bag of NEOFIL STONE FIX under continuous mixing till a uniform lump free consistency mix is achieved. For mixing process, a slow speed drill (200- 300rpm) fitted with a suitable paddle is recommended.
Allow the obtained mix to stand for 3 minutes and then remix before application.

Spread NEOFIL STONE FIX on the substrate to a uniform thickness using a toothed spatula, the first pass with its straight edge and the second pass immediately after, to the desired thickness using the toothed part.
Place the tiles onto the adhesive bed. Apply sufficient pressure on the tile during fixing it with slight twisting movement in order to ensure good contact with the adhesive.
In case of large size tiles, it is necessary to spread the adhesive also to the backside of the tile and then place the tiles into the adhesive bed.
Apply enough material that can be tiled during the adhesive’s open wet time.
Spreading large areas may result in drying the adhesive before tiles can be fixed causing poor adhesion.  

Remove excess adhesive with damp cloth before the material has set.  Joint grouting between tiles may be commenced 10 hours after tiles have been laid on the walls and 24 hours after tiles are laid on the floors.

Tools and equipment should be cleaned with water immediately after use. Hardened materials should be mechanically removed.


  • To achieve improve adhesion strength, it is recommended to replace water with ELASTOKOL
  • Stiffened mortar  must neither be diluted with water nor with fresh mortar
  • Do not use on metal or non-absorbing surfaces
  • Do not apply in rainy weather, high winds and sand storms
  • Do not apply under direct sun
  • Keep equipment cool and use cold water
  • Porosity of tiles and substrates has significant effect on adhesive strength of tiles
Additional Information
Health & Safety

NEOFIL STONE FIX can be harmful to skin as it contains cement powders which may releases alkalis when mixed with water.
During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.
In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.
If ingested, obtain medical attention immediately. Do not induce vomiting.
