Wet Film Thickness Gauge

Wet film thickness gauge (WFT) can be measured using a WFT Comb Gauge. The WFT is taken immediately after a coating has been applied so that any deviation from the specified thickness range can be immediately rectified while the paint is still wet, thereby reducing the amount of dried coatings which are outside the specified thickness tolerances.

Available in a range of sizes and in a variety of materials, the comb is a simple but effective tool to use. Place the comb perpendicular to the coating applied for a moment. When removed the wet film thickness is indicated between the wet and dry tooths.
