The figures behind it.

  • Litres per metre run

X-Calibur's guide to quantities is the joint's width times its depth: a 25 x 15 mm joint takes 0.37 litres per metre run.

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 X-Calibur technical data sheet before ordering.
