BEHIND THE NUMBERS

How this calculation works.

The same stated percentage produces different additions depending on its denominator. The calculator translates an existing product instruction and never selects a thinner or dilution rate.

Original basis: add = base×p; final basis: add = base×p/(1−p)Calculated with normalised units

A worked example

Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.

Original product volume
10 L
Manufacturer-specified percentage
10 %
Percentage basis
Added volume as percent of final total

Specified addition volume: 1.11 L

Only use a compatible addition and percentage explicitly permitted by the selected manufacturer. Coverage and product performance are not recalculated.

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.
