Concrete, Mortar and Masonry

Surfaces must be clean, free from grease, oil and loosely adhering particles. Suitable mechanical methods such as abrasive blast cleaning; high pressure water jetting at sufficient pressure (minimum 150 bar) and volume; scabbling or needle gunning. On “new” or smooth faced concrete, surfaces should be sand blasted. All surfaces must be as true and flat as possible. Blow holes and irregularities should be filled with suitable SikaTop / Monotop products.

Substrate absorbent concrete surfaces thoroughly with water to achieve a surface saturated dry (SSD) condition.

 For 20 kg Bag add about 4.8 – 5.2 liters clean, cold water to a clean, suitable mixing container. Slowly add the SikaCeram®-90 PK powder and mix for at least 3 minutes until a homogeneous mix, free of lumps is achieved. Do not mix more SikaCeram®-90 PK than can be used within the open time.

Do not add extra water or other ingredients after mixing.

Apply SikaCeram®-90 PK at 2-3 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 filed within 15 – 30 minutes.

Press tiles firmly into SikaCeram®-90 PK with a twisting action to ensure optimum adhesion.

1. Use 4 – 4.5 liters of clean water per 20 kg bag.
2. Mix well with a hand trowel. For large volume mixing use a slow speed drill (maximum 500rpm)
3. Apply with "V"-notched trowels for small tiles.
4. Apply with square notched trowel for bigger tiles.
5. Place the tiles firmly into the fresh adhesive.

Where ambient conditions may lead to rapid surface drying, the use of light water fogging for 48hrs, hessian or suitable water-based curing compound is recommended. Do not commence fogging until final set has been reached.

Application and mixing tools should be cleaned with water while material is still fresh. Hardened material can only be removed mechanically.
