Application Information

SUBSTRATE PREPARATION
Before grouting, ensure that the adhesive has completely dried and hardened. Adhesive should be left for 24 hours before applying the grout, unless rapid setting adhesive is used.
All tiles and joints must be clean and free from oil, grease or loose materials.
Remove the tile spacers and ensure that the grout joints are uniform and their widths do not exceed 6 mm to avoid slumping.

MIXING
To ensure proper mixing, a mechanically powered mixer or drill fitted with suitable paddle should be used.
0.360 litre of clean fresh water for each 1 kg Cemafill ULTIMA (water/powder ratio of 0.33 - 0.35 by weight) should be added to a clean container. The powder is then added slowly to the water while mixing continuously at low speed (400 - 600 rpm).
Mixing time should be continued for 3 minutes until a uniform consistency and free of lumps mixture is obtained. Allow a slake time for 10 minutes, then remix for additional 1 minute without adding any more water.

NOTES
Important: Adding too much water will weaken the joints, cause surface discoloration and promote the formation of cracks. Always follow the mentioned mixing ratio.

APPLICATION 
Using appropriate spatula or rubber float, fill with pressure the joints completely with Cemafill ULTIMA.
Immediately  remove the excess grout  by moving  the spatula or the edge of the rubber float diagonally to the tiles.
When  the grout starts to set (usually 20-30 minutes at normal conditions), use a damped sponge in a circular motion to remove the excess grout and level the joints.
After drying, clean the tiles surface using a dry cloth.
It is recommended to remove grout from the tile surfaces before full setting of the grout. Failure to do so may result in difficulty in removing any remains and makes it necessary to use a mechanical means in cleaning, which may scratch the tile surfaces.
