Consumption is dependent on the substrate, surface profile, roughness, size of the tiles, the joints between them and application technique (i.e. single spreading / floating method or double spreading / buttering method).

As a guide for a single adhesive layer:

Important: Avoid over-mixing to minimise air entrainment.

Requirement: Use a low speed electric single paddle mixer (<500 rpm) with spiral paddle for mixing.

1. Pour the recommended amount of clean cold water into a clean mixing container.
2. Gradually add SikaCeram®-205 Large powder to the water while mixing.
3. Mix thoroughly until a uniformly coloured, smooth mix is achieved.
4. Do not mix for 2–3 minutes to allow mixed product to ‘mature’.
5. Remix for ~30 seconds.

Important: Apply sufficient adhesive to ensure adequate ‘wetting’ of the backs of the tiles.

Important: Coverage on the back of the tiles must be 100 %.

Important: Tiling must be carried out on freshly applied adhesive. Exert adequate pressure to ensure 100 % complete and uniform contact with the adhesive to achieve optimum adhesion.

Important: If a skin forms on the surface of the adhesive, immediately remove the adhesive layer with a trowel, discard material and apply a fresh layer of adhesive.

Note: For tiles > 900 cm² (30 × 30 cm), the double-spreading (buttering) technique is always recommended.

1. Apply sufficient adhesive to the prepared fixing surfaces with the appropriate trowel / comb or applicator to the required bed thickness.
2. Adjust tiles if required.
3. Clean off surplus adhesive from tile face and between tile joints before the adhesive has dried.

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