Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Sealant volume = joint length × joint width × sealant depth. The volume is converted to milliliters, increased by the entered allowance and rounded up to full cartridges.

FAQ
Concrete Control Joint Sealant Calculator questions
Does this include backer rod?+
No. Backer rod is normally selected separately by joint width and the sealant manufacturer’s installation guidance.
Why use average joint dimensions?+
Saw cuts and formed joints can vary. Measuring several locations provides a better purchasing estimate.
Can any exterior sealant be used?+
Use a product rated for the substrate, exposure, expected movement and traffic conditions.
