Consumption
Consumption is dependent on the substrate, surface profile, roughness, size of the tiles, the joints between them and application technique.
As a guide for a single adhesive layer:
| Size of tiles | Notched trowel size | Consumption |
| Small | 3 mm | ~1,5 kg/m2 |
| Medium | 4 mm | ~1,6 kg/m2 |
| Large | 6 mm | ~2,5 kg/m2 |
MIXING
SikaCeram®-355 StarPaste does not require any mixing. Once material has been used and exposed to the air, to maintain its workability it is recommended to mix occasionally with a trowel.
APPLICATION
SikaCeram®-355 StarPaste is applied using a suitable notched trowel.
Apply sufficient adhesive to the prepared fixing surface with the appropriate trowel and comb to the required bed thickness. Apply sufficient product to ensure adequate ‘wetting’ of the backs of the tiles.
Tiling must to be carried out on freshly applied adhesive, exerting adequate pressure to ensure 100 % complete and uniform contact with the adhesive to achieve optimum adhesion.
If a skin forms on the surface of the adhesive, immediately remove the adhesive layer with the trowel, discard material and apply a fresh layer of SikaCeram®-355 StarPaste adhesive.
Adjust tiles if required.
Clean off surplus adhesive from tile face and between tile joints before the adhesive has dried.
After the required waiting time apply the appropriate grout into the tile joints.
The use of the product to lay tiles within the following limits is recommended:
| Substrate | Ceramic (porosity < 6 %) Stones (porosity < 2 %) | Ceramic (porosity ≥ 6 %) Stones (porosity ≥ 2 %) |
| Very absorbing | 1200 cm2 | 3600 cm2 |
| Absorbing | 1200 cm2 | 2200 cm2 |
| Wood | 1200 cm2 | 1200 cm2 |
| Non absorbing | - | 1200 cm2 |
- To lay tiles larger than 900 cm2 (e.g. 30 × 30 cm), the double-spreading (buttering) method of application is recommended.
CLEANING OF TOOLS
Clean all tools and application equipment with water after use. Hardened material can only be removed mechanically.
