Sealant quantity calculator
Enter the joint width, sealant depth and total length to see how many packs to order. Measure the joint rather than guessing the bead size.
Estimated order quantity
2 packs550 ml including waste (500 ml theoretical fill).
How it works
Width in millimetres × depth in millimetres × length in metres gives the volume in millilitres. The calculator adds your waste allowance and rounds up to whole packs.
Real use varies with changes in joint width along the run, backing rod, tooling, starts and stops, and what is left in each pack, so keep a margin.
