Calculation data
Enter the joint geometry, profile shape, allowance and cartridge volume. The calculator is not tied to a specific product, so it works for any sealant.

Sealant Consumption Calculator
A universal calculation for bathroom joints, window seams, skirting boards, wood, facades and other gaps.
Formula
- Rectangular joint: length, m × width, mm × depth, mm = ml.
- Triangular joint: rectangular volume × 0.5.
- Material with allowance: volume × (1 + allowance / 100).
What to consider
- For uneven or deep joints, allow 10-20% extra material.
- If the manufacturer specifies another joint profile or depth limit, follow the product technical sheet.
Calculation questions
How much sealant is needed for 1 meter of joint?
A rectangular 6×6 mm joint needs about 36 ml per meter before allowance. A 280 ml cartridge covers roughly 7-8 meters of that joint.
Why does the calculator include a triangular profile?
Corner joints are often tooled as a triangle, so the actual volume is roughly half of a full rectangular fill.
