- Thin-set adhesive: ≈ 39.8 kg (2 × 50 lb bags) — recommended trowel: 12mm notch, large format
- Grout — the tile sets the joint width, not you:
- ≈ 1.7 kg (1 × 10 lb bag) — 3mm joint, rectified / tight-set tile
- ≈ 2.9 kg (1 × 10 lb bag) — 5mm joint, natural or non-rectified tile
Adhesive: allow a little over on an uneven substrate, or if you back-butter large tiles — both eat more than a flat bed.
Grout: the 25 lb bag is the usual size (10 lb for small jobs). Buy it in one go and stick to a single bag size: bags from different batches can dry to slightly different shades.
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 — thicker tiles need more.
