APPLICATION INSTRUCTIONS SUBSTRATE QUALITY / PRE-TREATMENT IMPORTANT

Gypsum plaster and anhydrite screed substrates must have a maximum moisture content of 0.5 %.

IMPORTANT

Do not apply on metal or wood surfaces. Cementitious substrates must be sufficiently cured and dried (2–6 weeks). ▪ All substrates must be structurally sound, able to support the weight of the new tiling and provide astable and securely fixed background. Surfaces shall be clean, dry, free of any loose or friable particles, contaminants such as dust, dirt, oil, wax, polish grease, cement laitance or efflorescence. ▪ Use adequate preparation techniques to remove all traces of any materials that could reduce the product’s adhesion to the substrate. ▪ Smooth surfaces should be roughened lightly to improve adhesion. ▪ To confirm adequate surface preparation and coating adhesion, carry out a small trial before full application. ▪ Any small surface defects and variations in level, profile, or around exposed aggregates can be prefilled and levelled with an additional layer of SikaCeram®- 50 Tilofix to a maximum thickness of 5 mm, applied at least 24 hrs before full adhesive application. ▪ For larger and thicker areas of surface reprofiling and making good, use appropriate mortars from the Sika MonoTop® or SikaCeram® Floor Leveler range. ▪ Identify cracks in substrates and seal appropriately with Sikadur® epoxy resins. ▪ For applications in hot climates / environments, or on absorbent substrates, thoroughly pre-dampen the surface immediately prior to product application. Avoid any ponding / standing water on the surface. Surface must not be damp to touch. ▪ If a waterproofing layer is required, cement-based and acrylic-based Sika® waterproofing product / system must be applied to the substrate before tiling. ▪ MIXING Pour the recommended amount of clean cold water into a suitable, clean mixing container. 1. Slowly add SikaCeram®-50 Tilofix powder to the water and then mix thoroughly using a low speed (< 500 rpm) drill mixer until the material is fully mixed and lump free. Avoid entraining air into the mix by over mixing. 2. Allow the product to ‘mature’ for 2–3 minutes before remixing for 30 seconds. 3. The finished mix has a creamy consistency, uniformly coloured and is easy to apply and spread. 4. APPLICATION IMPORTANT Avoid application in direct sunlight and/or strong wind / draughts. SikaCeram®-50 Tilofix is applied using a suitable square notched trowel. Apply adhesive to the prepared fixing surface with the appropriate trowel and comb to the required bed thickness. Coverage on the back of the tiles should be 100 %. 1. Tiling must be carried out on freshly applied adhesive, exerting adequate pressure to ensure complete 2. and uniform contact with the adhesive for optimum bond. 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®-50 Tilofix adhesive. 3. 4. Adjust tiles if required. Clean off surplus adhesive from tile face and between tile joints before the adhesive has dried. 5. After the required waiting time apply the appropriate grout into the tile joints. 6. SikaCeram®-50 Tilofix is ideal for laying absorbent ceramic and vitrified tiles up to 900 cm2 (e.g. 30 × 30 cm), for indoor application only. Tiles > 900 cm2 (e.g. 30 × 30 cm), the double-spreading (buttering) technique is always recommended.

7. CLEANING OF TOOLS

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