Coverage calculator
How much you need.
The arithmetic uses Mapei's published consumption for Mapeband TPE and the pack sizes we stock. Set your own wastage allowance.

The figures behind it.
- Butt joints between two strips of Mapeband TPE must be carried out by overlapping and bonding at least 5 cm of the central part in TPE by either hot-welding or cold-welding, as illustrated previously.
Butt joints between two strips overlap by at least 5 cm. Add your overlaps to the length, or use the wastage field.
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.
