Product facts


Cement-based powder containing polymer modifiers. Added light stable pigments. Contains quartz sand with grain sizes up to 0.4 mm.


Available in grey, pale grey, graphite and steel grey.
Colour swatches available on request.



0,8 - 1,3 kg per m² depending on tile size and joint width.


20 kg PE lined paper bags.



Grouting can be made approximately 2 days after completion of fixing. Joints should be clean, dry, and free from loose particles. Joint depth should appear uniform. For grouting of very absorbent tiles, Alfix CeraFill 5 colour should be used. For joint widths exceeding 15 mm, Alfix CeraFill 20 should be used.

Expected Result

Finished joints should be evenly filled and the colour should appear uniform.
The following conditions may affect the natural properties of the cement and cause colour differences:

  • Early cleaning with wet sponge may lighten the colour. This phenomenon is most likely to occur in case of dark colours.
    Remedy: Clean off with acidic cleaner, such as Alfix Acid Wash.
  • Rapid drying may brighten the colour and produce a weak joint.
    Remedy:Keep the surface damp for optimum hydration of the grout. Wet with damp sponge.
  • Repairs or visible seams after working breaks may cause colour differences.
    Remedy: Remove the joints mechanically and re-grout the area. Wipe over and clean off the tiles several times with slightly damp sponge.
  • Moist from substrate and uneven absorption from tile edges may cause a locally darker colour. Remedy:Wash the area several times with a mixture of soap flakes and water.

How to use


Surface preparation

How to use

Add 0.19 - 0.21 litre clean, cold water per kg powder. Pour the water into a clean container and add the powder while stirring thoroughly with mixing drill. Keep stirring until the consistency is completely uniform, smooth, and lump-free. Allow the mixture to rest for a few minutes before use. Apply Alfix CeraFill 16 classic to the surface with a soft rubber squeegee while working diagonally over the joints ensuring that they are completely filled. Remove excess grout immediately while working.
When the grout begins to set, after 30-45 minutes, start to slurry off the area using damp sponge frequently rinsed in clean water. Wipe over tiles in broad sweeps until joints appear even and filled. Finally, clean off and finish tiles and joints with only slightly damp sponge. Any remaining grout film on the surface can be removed after 12 - 24 hours using an acidic cleaner, e.g. Alfix Acid Wash. In most cases cleaning with clean water, e.g. added vinegar, will be sufficient to remove grout film or efflorescence.


This grout contains colour pigments which may cause staining to some types of tiles - stains which can be difficult to clean off. To ensure that tile and grout are compatible, trial a small area. Switch off any underfloor heating.
Note that the temperature of mixing water will influence setting time.
Protect the joints from heat, draught, and other climatic conditions which will cause premature drying.
To prevent premature drying dampen joints for approx. 24 hours (use e.g. wet sponge) in order to obtain complete hardening. Do not cover areas just grouted with plastic foil or sheets.


Grout residues on tiles and tools should be removed with water before the mix begins to set. Cement-based products harden when mixed with water, hence do not pour surplus adhesive into the drain system.
