How to Use:

1. Prepare the Substrate: Ensure it is clean, dry, sound, and primed if porous or dusty.

2. Apply Adhesive: Spread with a notched trowel over a small area (max. 1 m² at a time).

3. Fix Tiles: Press tiles firmly into place. Clean excess adhesive immediately.

4. Grout: Wait 24–48 hours for adhesive to dry, then apply grout with a squeegee or float.

5. Clean: Wipe tiles with a damp sponge within 5–10 minutes. Buff dry once hardened.
