  • Wet and Dry Film Thickness Formulae

    From the above equations, wet film thickness (WFT) may be easily calculated for a specified dry film thickness (DFT). If the wet film thickness is known the coverage of a coating in square feet per gallon may be calculated using the following formula: Coverage in 'Square Feet Per Gallon' = 1604.17 Divided By the 'Wet Film Thickness in MILS

    01/04/2009· In my opinion, a DFT of 6–10 mils of paint on most industrial equipment is far too much. As I told R.A. in a previous Painting Clinic, “...at Westinghouse Research Labs., we specified a dry film thickness of 1 mil for each coat of paint on all test panels.
