Cartridges to buy
Whole quantities are rounded up.
How it's calculated
Sealant volume = joint length × width × depth × (1 + waste ÷ 100). Cartridges = volume ÷ cartridge volume, rounded up.
Calculations use consistent units for your selected measurements. The waste allowance is applied once to the measured requirement. Whole purchase quantities are rounded up.
What this estimate includes
For a rectangular joint cross-section. Tooling losses, backer rod profile and variable joints affect actual usage.
