WFT (Wet Film Thickness) / DFT (Dry Film Thickness) / Convert mils to microns
% solids by volume = +/- 2%
1 mil equal to 1/1000 of an inch (2.54cm) – 25.4 microns rounded within +/- 2% in volume
If surface has a profile allow +10-30% spread rate eg. waves on galvanised iron 20% extra product

NOTE: The number of coats necessary to achieve at least 100 microns / 4 mils DFT over the tallest peak of rust.
If surface profile is 25-50 microns / 1-2 mils the minimum WFT application is 300 microns / 12 mils and 150 microns / 6 mils dry, which will allow to fill a surface profile and to have at least 100 microns / 4 mils of DFT over the top of tallest peak of rust.
