## The maker's figures

| Figure | The maker's words |
|---|---|
| 0.5 m² a kilogram | “10mm x 10mm Square Notch Trowel 0.5m²/kg” |
| 0.435 m² a kilogram | “Trowel 10mm x 20mm Round Notch Trowel Coverage ^ 0.435m²/kg” |
- The conditions the maker names: Each figure is for the notch, bed, tile or joint the maker names beside it. An uneven surface, a larger notch or buttering the backs of the tiles takes more.
- Waste: None of these figures adds anything for what is left in the bucket or spilt.
