The figures behind it.
- With a single cartridge, approximately 3 metres of bead with a diameter of from 6 to 13 mm may be formed.
- Each cartridge forms approximately 3 metres of Mapeproof Swell.
- Consumption: approximately 320 ml per 3 linear metres
- The normal size of the bead is from 6 to 13 mm.
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.
