MEASURE FIRST

How to prepare your inputs

Use the designed joint dimensions or total specified coating consumption. Confirm coats, thickness and usable product quantity on the datasheet.

How this calculation works

mL = length m × width mm × depth mm. Triangular fillets use half the rectangular volume. Add allowance and round cartridges up.

Worked example

A 10 m rectangular joint 10 × 10 mm uses 1,000 mL before allowance.

Assumptions & exclusions

Quantity estimate only. Joint design, movement capability, backing rod, adhesion and product selection need the appropriate datasheet. Do not assume these dimensions suit your joint.

Your next step

Have the applicator confirm system compatibility, substrate preparation, penetrations, cure time and required inspections.

What if my shape or product is different?

Use dimensions and product data that match the stated method. For complex work, calculate separate sections or obtain a project-specific take-off. Do not apply simple geometry to structural or compliance decisions.

Why are quantities rounded up?

Whole bags, packs, sheets or cartridges round up to purchasable units. Decimal area or volume results are planning figures; confirm order increments with the supplier.

Are my entries saved?

No. Entries remain in the current browser page and clear on reload. Printing can save your results and inputs as a PDF on your device.
