What it is for, in the maker's words: “High-performance, quick-setting, deformable cementitious adhesive with no vertical slip for ceramic tiles and stone material stable in the presence of humidity (thickness of adhesive up to 10 mm)” (Mapei Keraquick S1 technical data sheet (UK), read 12 October 2026).

## The maker's figures

| Figure | The maker's words |
|---|---|
| about 2 kg a square metre | “Mosaics: ca. 2 kg/m2” |
| about 3 to 4 kg a square metre | “Standard size tiles: ca. 3-4 kg/m2” |
| about 4 to 6 kg a square metre | “Large tiles, floors, exteriors: ca. 4-6 kg/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.
- 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 10 kg bag | A 20 kg bag |
|---|---|---|
| about 2 kg/m² (“Mosaics: ca. 2 kg/m2”) | about 5 m² | about 10 m² |
| about 3 to 4 kg/m² (“Standard size tiles: ca. 3-4 kg/m2”) | 2.5 to 3.3 m² | 5 to 6.7 m² |
| about 4 to 6 kg/m² (“Large tiles, floors, exteriors: ca. 4-6 kg/m2”) | 1.7 to 2.5 m² | 3.3 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.
