- Thin-set adhesive: ≈ 2 bags (22.7 kg) — recommended trowel: 10mm notch
- Grout — the tile sets the joint width, not you:
- ≈ 1 bag (11.3 kg) — 3mm joint, rectified / tight-set tile
- ≈ 1 bag (11.3 kg) — 5mm joint, natural or non-rectified tile
It's the tile that decides the joint, not the setter — dry-lay a section to find your width. Assumes 9.5mm tile depth; adjust for your product.
