Formula and assumptions
How this calculation works.
Separate measured detail bands from broad surface coverage and remove explicitly measured shared areas once. Net bands = Σ(length × specified band width × count) − shared-area deduction; liquid = net bands × coats / coverage × allowance.

Before you purchase
Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.
All product dimensions, coverage, density, allowances and joining rules must come from your supplied plan or selected product. No building-code values are inserted.
