The Calculation
How the Formula Works
Three steps from specific gravity to order quantity. Understanding each one helps you cut waste and spec with confidence.
Theoretical Coverage
One pound of powder has a maximum theoretical coverage determined by its specific gravity and target film thickness. Denser powders cover less area per pound.
192.3 ÷ (SG × mils DFT) = ft²/lb
Transfer Efficiency
Not all powder sprayed reaches the part. Transfer efficiency accounts for overspray losses, and a well-tuned electrostatic line typically runs at 60–75%.
Theoretical coverage × TE% = effective ft²/lb
Powder Required
Divide your total surface area by the effective coverage rate. Add a safety margin, typically 10–15%, for startup waste, colour changeovers, and complex geometry.
(Area × Coats) ÷ Effective coverage = lbs needed
Combined Reference Formula
Step 1 — Coverage rate
192.3 ÷ (SG × mils) × TE% = ft²/lb
Step 2 — Powder needed
(Area × Coats) ÷ ft²/lb = lbs required
Full expression
lbs = (Area × Coats × SG × mils) ÷ (192.3 × TE%)
