The figures behind it.

400-600 g/m² in two coats, which corresponds to a final thickness of approximately 300-450 µm (2 coats of product).
If just one coat is applied, a dry final thickness of at least 200 µm (consumption of approximately 300 g/m²) is required.

Consumption on site depends on the substrate, the tool and the applicator, which is why wastage is yours to set. The result is a quantity to plan and quote with, not a guarantee of coverage. Confirm the system against the current Mapei technical data sheet before ordering.
