Consumption of SikaCeram®-545 is dependent on the surface profile and roughness of the substrate as well as on the size of the tiles and the joints between them.

As a general guide, the approximate consumption can be calculated by volume, where ~1.9 kg/m²/mm of mixed material is required, depending
from colour.

Consumption of tile grout can be also calculated through the following formula:
((L1+ L2) x W x T x D ) / (L1 x L2) , where:
▪ L1 = Length of tile (mm) - First side
▪ L2 = Length of tile (mm) - Second side
▪ W = Joint width (mm)
▪ T = Tile thickness (mm)
▪ D = Fresh mortar density of tile grout (kg/l)
Note: Final result will be in kg/m².
Note: All figures are theoretical and for indicative purpose only. They do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage, etc.

18 kg bag will yield ~11.9 L

Immediately after setting the tiles, rake the joints clean to a uniform depth corresponding to the thickness of the tile. Allow 24 hours for the adhesive to set before grouting.

Pour the recommended amount of water into a suitable, clean mixing container. Stir slowly, whilst slowly adding the SikaCeram®-545 powder to the water and then mix thoroughly using a low speed (<500 rpm.) drill mixer until the material is fully homogeneous and lump free.
After mixing, leave the product to stand and ‘mature’ for ~3 minutes, then briefly stir again prior to application. The finished mix has a very creamy consistency, is uniformly coloured and it is easy to apply and spread.

Note: Allow at least 24 hours between fixing tiles and grouting.

SikaCeram®-545 is applied using a rubber blade or trowel using cross-hatch techniques, taking care to ensure the joints are filled uniformly across
the whole width and along their full length.
Using the same blade/trowel in a vertical position, remove the excess from the surface of the tiles.
When the material starts to set, it is possible to begin the initial cleaning step, using a damp sponge. The remaining grout traces on the tile surfaces can easily be removed the next day by wiping with a clean, soft dry cloth.
Avoid application in direct sunlight and/or in excessive draughts or strong winds.

Clean all tools and application equipment with clean water immediately after use. Hardened / cured material can only be mechanically removed.
