How to Use

1. Ensure concrete is clean, sound, level and free from oil and grease. Remove cement laitance, formwork traces and loosely adhering particles by suitable preparation such as sandblasting or high-pressure water jetting.
2. Pre-wet absorbent substrates to a saturated-surface-dry condition.
3. Add the powder to approximately 4.0–4.6L of clean water per 20kg bag. Mix for 3–5 minutes using a handheld or mechanical mixer until homogeneous and lump-free.
4. Allow the mixture to stand for 1–2 minutes, then remix thoroughly for another minute.
5. Apply with a notched trowel. Back-butter tiles for improved contact and coverage, particularly tiles larger than 30 × 30cm or tiles with deep grooves. Ensure adhesive fills the grooves.
6. Press tiles firmly onto the substrate and immediately tamp into position. Complete adjustments within approximately 20 minutes and ensure proper adhesive contact with the substrate.
7. Follow Sika's stated curing guidance: walls after 7–8 hours depending on temperature, floors after 24 hours, and full traffic after 14 days. Confirm the intended subsequent wall or floor operation before proceeding.
8. Clean unhardened material from tools with water. Hardened material can only be removed mechanically.
