Wet Film Thickness Gauge
Wet film thickness gauges are used when a specific dry or wet film thickness are recommended/specified.
To calculate a required dry film thickness (d.f.t) from a wet film thickness (w.f.t) it is necessary to know the volume solids content of the paint coating.
The solids content can be obtained from the products technical data sheet.
Calculation formula for a dry film thickness from the wet film thickness d.f.t.=w.f.t. X % volume solids ÷ 100
To measure the wet film thickness required : w.f.t.=d.f.t. X 100 ÷ % volume solids.
