## The maker's figures

| Figure | The maker's words |
|---|---|
| 2 to 3 kg a square metre | “Mosaics and small size tiles (trowel No. 4/5): 2-3 kg/m²” |
| 4 to 5 kg a square metre | “Medium size tiles (trowel No. 5/6): 4-5 kg/m²” |
| at least 6 kg a square metre | “Large sizes, floors, exteriors (trowel No. 6/10): > 6 kg/m² and over” |
- 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.
- A range, not one figure: Mapei UK gives a range. To buy enough, plan on the end that needs more: the smaller area a bag, or the higher kilograms a square metre.
- Waste: None of these figures adds anything for what is left in the bucket or spilt.

## What one bag covers at the maker's rate

| Rate | A 20 kg bag |
|---|---|
| 2 to 3 kg/m² (“Mosaics and small size tiles (trowel No. 4/5): 2-3 kg/m²”) | 6.7 to 10 m² |
| 4 to 5 kg/m² (“Medium size tiles (trowel No. 5/6): 4-5 kg/m²”) | 4 to 5 m² |

Arithmetic on the maker's figure: the bag's kilograms divided by a rate a square metre, or times an area a kilogram, with nothing added for waste.
