200x150 Windmill Tile Pattern
This is the windmill module at half scale: 200x150 mm rectangles turning around a 50x50 mm square, the size the closure rule demands (200 minus 150). The smaller format puts far more turning modules in the same area, so the pinwheel effect becomes the surface's texture rather than its structure — which is what makes it work on splashbacks, shower walls and small cloakroom floors, where a large-format windmill would only fit a module or two. For the same pattern in a large format, see the 400x300 windmill.

Adhesive & grout
- Thin-set adhesive: ≈ 20.3 kg (2 × 20 kg bags) — recommended trowel: 6mm notch
- Grout — the tile sets the joint width, not you:
- ≈ 4.4 kg (1 × 10 kg bag) — 3mm joint, rectified / tight-set tile
- ≈ 7.3 kg (1 × 10 kg 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: bag sizes vary by brand — 10 kg is a common one (2.5 kg 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.
