## The maker's figures

| Figure | The maker's words |
|---|---|
| up to 37 m² per 11 kg bag | “thus one 11kg bag of ARDEX MG will grout up to 37m² of tiling” |
| 0.29 kg a square metre | “Example Tiles 150mm x 150mm x 5mm; joints of 3mm:300 x 5 x 3 x 1.45 ÷ 150 ÷ 150 = 0.29kg/m²” |
- 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.

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