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

Assumes a rectangular, constant-depth bead. Backer rods and joint shape change the sealant volume.

Quantity and arithmetic estimates only. Use project specifications for installation and design requirements.
