Sealant Tube Quantity Calculator

How the sealant tube quantity calculator works

For a fully filled rectangular cross-section, net millilitres = length in metres × width in millimetres × depth in millimetres. Dividing millilitres by 1,000 gives litres. The entered width and depth must be positive and constant over the joint length.

Required millilitres = net millilitres × (1 + allowance percentage / 100). Tubes to buy = ceil(required millilitres ÷ usable millilitres per tube). Any positive requirement below one tube rounds to one tube. Zero length produces no tubes or cost.

Purchased volume uses whole tubes, and material cost = tubes × quoted tube price, rounded half-up to cents. An entered allowance is not a manufacturer coverage guarantee. Partial tubes, residual product, multipack requirements, tools, labor, delivery and tax are excluded.

Use this only after selecting the joint geometry and product. The tool does not recommend width/depth ratios, backer rod, application conditions, adhesion, movement accommodation or repair technique. Nonrectangular beads need a different cross-sectional area. QUIKRETE’s joint calculators illustrate the product-volume purchasing workflow.

Worked example

100 m of joint at 10 mm width and 10 mm filled depth contains 10 L. A 10% allowance requires 11 L. At 300 mL per tube, 36.667 tubes rounds to 37. At an illustrative 6 per tube, cost is 222. Halving length to 50 m requires 19 tubes and 114.

Sources and assumptions

The source material explains the underlying calculation or pricing structure. Entered prices, costs, schedules and scenario choices are your assumptions; this tool does not obtain supplier quotes or predict actual results.
