How to Use This Calculator
  1. Enter your spray tip size (thousandths of an inch) and operating pressure (PSI).
  2. Input coverage rate (sq ft/gal) from the coating manufacturer's data sheet.
  3. Enter material viscosity (KU) and total job area (sq ft).
  4. Review Flow Rate (GPM), Material Needed (gal), Overspray Factor, and Spray Time (hrs).
  5. Thin material if viscosity is high and re-check the Thinner Needed output.
