Add about 5.2 – 5.4 liters clean potable water to a 20 kg bag

Minimum 2 mm

Maximum 5 mm

15 minutes

Once the tiles are set into the mortar, they can be adjusted for up to approximately 15 minutes (at +25°C)

The consumption depends on the surface profile and roughness of the substrate and the placing technique (simple placing or back-back-“buttering”). Consumption 1 / 3 - One 20 kg bag will cover approximately 5 – 7 m²

• The substrate must be structurally sound, clean and free from dirt, oil, grease or other contaminants and loose or friable particles.
• Weak concrete and/or cement laitance must be removed by suitable mechanical means such as abrasive blast cleaning; high pressure water jetting (minimum 150 bar); scabbling or needle gunning.
• On “new” or smooth faced concrete, surfaces should be sand blasted.
• Repairs to the substrate, filling of blowholes/voids etc. must be carried out using appropriate products from the Sika® Rep range of materials or Sika® MonoTop range.
• Allow a waiting time of 24 to 48 hours before placing the tiles.
• All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.
• In normal conditions, no primer is required.
• Use clean, cool water to pre-dampen the substrate especially if the substrate is very porous and if the temperature is high and relative humidity low - do not leave any standing water.
• Variations in level must be less than 5 mm, measured with a 2 meter straight edge.
• If necessary, the substrate should be leveled prior to application.

• Add about 5.2 – 5.4 liters clean potable water to a 20 kg bag. 
• Mix mechanically using a forced action mixer or slow speed drill (< 500 rpm) and mixing paddle for at least 3 minutes until a homogeneous mix, free of lumps is achieved.
• Do NOT use a normal free fall concrete mixer.
• Do not mix more material than can be used within the open time.
• Leave material to stand in mixing container until the majority of bubbles have dispersed (minimum 2 minutes).
• Then remix the material for 15 seconds – the product is now ready for use.

• Apply SikaCeram®-80 Ceramic KE at 2 - 5 mm thickness directly to the concrete substrate, using a notched trowel and spread the mortar evenly over the area to be tiled.
• Cover only an area that can be tiled within 15 - 30 minutes
• Apply with “V”-notched trowels for small tiles.
• Apply with square notched trowel for bigger tiles.
• Press tiles firmly into the mortar with a twisting action to ensure optimum adhesion.

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