What to do with the number
Bead width and depth determine real coverage, so a manufacturer bead-size chart is more reliable than a generic tube estimate. Use the exact coverage for your planned bead size whenever the sealant label provides it.
Planning estimate
Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
