Coverage calculator
How much you need.
The arithmetic uses Mapei's published consumption for Mapefer 1K and the pack sizes we stock. Set your own wastage allowance.
The figures behind it.
- 100 g/m per reinforcing rod with an 8 mm diameter and 200 g/m per reinforcing rod with 16 mm (2 mm of applied product).
- Pour 1.0-1.1 l of clean water into a clean container and, while mixing, slowly disperse 5 kg of Mapefer 1K.
- 100 parts by weight of Mapefer 1K with 20.5 % water.
Figures are for 2 mm of applied product. Mapei gives them for 8 mm and 16 mm bars only.
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.
