## The maker's figures

| Figure | The maker's words |
|---|---|
| about 1.4 m² per 4 kg bag | “A 4kg unit of ARDEX WA is sufficient for approximately 1.4m2 of tiles” |
| 2.2 m² per 4 kg bag | “2.2m2 of medium or small mosaics” |
| up to 8 m² per 4 kg bag | “thus one 4kg unit of ARDEX WA will grout up to 8.0m2” |
| 0.5 kg a square metre | “Example Tiles 150mm x 150mm x 5mm; joints of 5mm:300 x 5 x 5 x 1.5 ÷ 150 ÷ 150 = 0.5kg/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
