Application

Application Information

Fresh mortar density

1.6± 0.2kg/litre when wet mix at 25ºC

Layer thickness

Minimum 2mm

Maximum 5mm

Ambient air temperature

Minimum: +8ºC

Maximum: +40ºC

Mixing ratio

Add about 4-4.5 litres clean potable water to a 20kg 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 5 minutes). Then remix the material for 15 seconds- the product is now ready for use. If open time is exceeded or the adhesive dries prematurely, remove tiles and re-apply using fresh material

Substrate temperature

Minimum: +8ºC

Maximum: +35ºC

Open Time

20 minutes (25ºC) (EN 1346)

Curing time

Before jointing/ grouting works - Min 24 hours

Before opening to light foot traffic - Min 24 hours

Before opening to full traffic  - Min 14 days

Adjustability time

Once the tiles are set into the mortar, they can be adjusted for up to approximately 20 minutes (at +25ºC)
Consumption

Consumption

The consumption depends on the surface profile, roughness of the substrate and the placing technique (simple placing and regular surface). A 20 kg bag will cover approximately 4- 5.5 m2.
Application steps

APPLICATION INSTRUCTIONS

Apply SikaCeram®-80 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 withing 10 - 20 minutes. Apply with "V" -notched trowels for small tiles. Apply with square notched trowels for medium tiles. Press tiles firmly into the mortar with a twisting action to ensure optimum adhesion.

CLEANING OF EQUIPMENT

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