How to Use This Calculator

Enter spray gun transfer efficiency (%) for the selected application method (conventional, HVLP, airless, electrostatic).
Enter total coating volume to apply (liters) and solids content (%) of the paint.
Read actual coating needed (liters) after accounting for overspray loss.
Compare transfer efficiency across spray methods — electrostatic typically achieves 85-95% vs. 25-45% for conventional.
Use efficiency data to calculate material cost savings and VOC emission reductions from switching methods.
