1. Importance of Actual Paint Consumption

The calculation of actual paint consumption is crucial for cost accounting and actual order quantity, as it provides a data foundation to help users plan their coating purchases and budget more accurately.

2. Calculation Method of Actual Paint Consumption

Actual paint consumption can be calculated based on the actual coating rate, and the formula is as follows:

Actual Paint Consumption = Coating Area × Dry Film Thickness × (1 + Loss Rate) / Theoretical Coating Rate × (1 - Loss Rate)

3. Example Calculation

For example, if the interior coating area of a tank is 1600㎡, and the coating is applied in two coats with a dry film thickness of 120μm, the solid content by volume is 60%, and the loss rate is 35%, we can calculate the actual paint required:

First, calculate the loss factor:

Loss Factor = 1 - 35% = 0.65

Then, calculate the actual paint consumption using the formula:

Actual Paint Consumption = 1600m² × 120μm × 0.65 / Theoretical Coating Rate × 0.65

Suppose the theoretical coating rate is 8 m²/L (this value must be determined based on the specific product specifications), then:

Actual Paint Consumption = 1600 × 120 × 0.65 / 8 × 0.65 ≈ 500L

Conclusion: This tank requires approximately 500 liters of this coating.

4. Conclusion

By accurately calculating actual paint consumption, users can optimize coating procurement and usage, reduce waste, and more effectively control project costs. Understanding the factors that affect actual paint consumption, such as loss rate and dry film thickness, is crucial for pcise calculation.
