Find the linear feet a tube of caulk seals.
A tube holds a fixed volume, and the bead's cross-section determines how far that volume stretches. Dividing the joint length by the per-tube coverage gives the tubes needed. Caulk is sold by volume but used by length, so converting to linear feet tells you exactly how many tubes a job takes.
Caulk Coverage
Linear ft/tube = (tube cu in / (bead width x depth)) / 12
Linear ft/tube = (tube cu in / (bead width x depth)) / 12 A tube holds a fixed volume, and the bead's cross-section determines how far that volume stretches. Dividing the joint length by the per-tube coverage gives the tubes needed.
