WebFor example, if a coating specifies you apply it at 500 microns WFT (Wet Film Thickness) and the volume solids of the product are 50% then once dry the DFT (Dry Film Thickness) reading will be 250 microns. Some coatings are 100% volume solids which means nothing thickness will be lost between WFT and DFT. WebIn order to calculate the dry film thickness (DFT) required to attain your desired Wet Film Thickness (WFT), you’ll need to use the following formula: WFT= DFT/VS . Conversely: DFT = WFT x VS. WFT- Wet Film thickness DFT= Dry Film Thickness VS= Volume Solids as a decimal (60% = .60)

WebDry film thickness, or DFT is a measurement of the dry and cured material after all liquid has evaporated. DFT = WFT x % volume solids.
