Consumption is always dependent on the substrate surface profile and roughness, as well as on the application technique (single adhesive layer on the substrate, or with an additional 'buttering' layer on the back of the tiles. As a guide:

Pour the recommended amount of water into a suitable, clean mixing container. Whilst stirring slowly, slowly add the SikaCeram®-230 Mosaic powder to the water and then mix thoroughly using a low speed (~500 rpm) electric mixer until a completely homogeneous and lump-free mix is achieved.
After mixing, leave the material to stand and ‘mature’ for a few minutes, and then briefly stir again immediately prior to application. The resulting mix has a very creamy consistency and is easy to apply and spread.

• SikaCeram®-230 Mosaic is applied using a notched trowel.
• Apply sufficient product to ensure complete ‘wetting’ of the back of the tiles.
• Tiling must to be carried out on freshly applied adhesive, applying adequate pressure to ensure complete and uniform contact with the adhesive and thus optimum bond. If a film is seen to form on the surface, the adhesive has been left for too long; should this happen, then immediately remove the adhesive layer with the trowels, discard this material and apply a fresh layer of SikaCeram®-230 Mosaic adhesive.
• Avoid application in direct sunlight and/or strong wind / draughts.
• To lay glass mosaic on net backing, dilute SikaCeram^® Improver with water in 1:1 ratio. Blend SikaCeram®-230 Mosaic with the mixture obtained. The resulting product provides an extremely tenacious bond and is highly flexible while maintaining the creamy consistency obtained when only water is used for mixing.

• The use of the product to lay not-absorbing tiles of maximum size up to 2025 cm² (e.g. 45x45 cm) indoors, and 900 cm² (e.g. 30x30 cm) for outdoor is preferable. These limits are valid for cementitious, non-heating substrates.

• To lay tiles larger than 900 cm² (e.g. 30x30 cm), the double-spreading (buttering) method of application is always recommended.

Thoroughly clean all tools and equipments with clean water before the product has set, preferably immediately after use. Once hardened the product can only be removed by mechanical means.
