Coverage calculator
How much you need.
The arithmetic uses Mapei's published consumption for Primer SN and the pack sizes we stock. Set your own wastage allowance.
You need
x 20 kg kit (A 16 kg + B 4 kg)
- Data sheet quantity
- 6-14 kg
- With 10% wastage
- 6.6-15.4 kg
The figures behind it.
- 0.3-0.70 kg/m² per coat depending on the characteristics of the substrate such as roughness, absorbency, temperature, etc.
- Add Mapecolor Paste if required and up to 50% by weight of quartz sand according to the room temperature (to even out rough surfaces).
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.
