Read the denominator in a supplied dilution percentage.
Does ten percent mean of original product or of final total?

Use this decision sequence
- Locate the percentage and basis in the selected manufacturer instruction.
- For a percentage of original volume, multiply original product by that percentage.
- For a percentage of final volume, solve for the addition using the final-total denominator.
- Do not transfer the arithmetic to another additive or infer coating coverage from the new total.
Keep the quantities distinct
| Quantity or assumption | How to use it |
|---|---|
| 10% of original | Addition equals 0.10 times original. |
| 10% of final | Addition equals original×0.10/0.90. |
| Product compatibility | Must come from the manufacturer, not from the ratio calculation. |
Worked comparison
For an illustrative 10 L original product, 10% of original is a 1 L addition and 11 L total. A specified addition that must be 10% of final volume instead requires 10×0.10/0.90 = 1.1111 L, giving 11.1111 L total. The two totals differ even though both instructions contain the words ten percent.
Check before using the estimate
Only translate an applicable manufacturer-specified addition; do not choose a thinner, rate or mixing recipe.
All dimensions, product properties, prices and specifications in this example are illustrative arithmetic inputs. Use the values from your measured plan, selected product data sheet and supplier quote. This guide does not choose construction specifications or certify safety.
