Paint and Powder Coating Coverage
How much paint or powder is needed to coat this area at the specified film thickness?
Theoretical and practical coverage, material quantity and cost for liquid paint (from volume solids) or powder coating (from density) at a dry film thickness and transfer efficiency.

How this tool works
Inputs, units and where to find them
| Input | Unit | Typical source |
|---|---|---|
| Coating | choice | Liquid paint or powder. |
| Area to coat | m² | Total surface area including both sides and edges where coated. |
| Dry film thickness | µm | Specified dry film thickness per coat. |
| Volume solids (liquid) | % | Volume solids from the paint data sheet (liquid only). |
| Powder density (powder) | g/cm³ | Specific gravity of the powder from its data sheet (powder only). |
| Transfer efficiency | % | Share of material that reaches the part (spray about 30–70%, electrostatic powder about 60–95% with reclaim). |
| Price per litre or kilogram | AUD | Cost per litre (liquid) or kilogram (powder). |
Method and formulas
- Liquid: theoretical coverage (m²/L) = 10 × volume solids % ÷ DFT (µm).
- Powder: theoretical coverage (m²/kg) = 1000 ÷ (density × DFT).
- Practical = theoretical × transfer efficiency; quantity = area ÷ practical coverage.
- Example: 50 m² at 75 µm with 60% solids needs about 9.6154 L.
Limitations
- Surface profile, overspray on complex parts and mixing losses add to consumption.
- Multiple coats: calculate each coat separately.
- Example values are illustrations. Replace them with values for your actual task.
Typical uses
- Estimate paint or powder for a job
- Quote coating cost per part or per square metre
- Compare application methods
Who it is for
- Coating supervisors
- Estimators
- Fabrication managers
What you get
- Theoretical coverage
- Practical coverage
- Quantity needed and cost
- Cost per square metre
Interpreting the result
- Measure actual consumption on a few jobs to calibrate the transfer efficiency.
