1. Importance of Theoretical Coverage Rate

For both owners and contractors, the coating rate of the coating material is a key factor in calculating the amount of coating required and estimating costs. It can also serve as a basis for the contractor's cost accounting, helping with project cost estimation. Theoretical coverage rate refers to the area (in square meters) that can be coated with one liter of coating material on a smooth surface without any loss, and the unit is m²/L.

2. Calculation Formula for Theoretical Coverage Rate

The theoretical coverage rate can be calculated using the following formula:

Theoretical Coverage Rate = Volume Solid Component × 10 / Dry Film Thickness

3. Example Calculation

Take an inorganic coating as an example. Its volume solid content is 60%, and the specified dry film thickness is 75μm. We can calculate its theoretical coverage rate:

Theoretical Coverage Rate = 60 × 10 / 75 = 8 m²/L

4. Conclusion

Mastering the calculation method of the theoretical coverage rate is crucial for reasonable planning of coating usage, cost control, and improving construction efficiency. With this calculation, the construction team can more accurately predict the required coating amount, avoid waste, and ensure the accuracy of the project budget.
