Sealant cartridge quantity Calculator
Calculate rectangular or triangular joint volume, waste and whole cartridges to buy. This free sealant cartridge quantity calculator shows the calculation and its assumptions so you can compare your own figures.
Your results
Calculate rectangular or triangular joint volume, waste and whole cartridges to buy.
Calculated outcomes
- Net Volume ML
- 250 mL
- Purchased Volume ML
- 300 mL
- Surplus Volume ML
- 25 mL
Assumptions and estimates
- Geometric material estimate for rectangular or triangular joints. Manufacturer joint-design, backer-rod, usable-volume and application specifications take precedence. Not a structural, fire-stopping or waterproofing certification.
- Method: Rectangular volume in mL = length in m × width in mm × depth in mm. Triangular joints use half that volume. Apply waste and round required cartridges up.
- Use actual joint dimensions and usable cartridge volume. Manufacturer joint-design/application guidance takes precedence; no fire, structural or waterproofing certification.
