Wet Film Thickness Gauge is a simple and yet very useful tool used to measure the thickness of a liquid (paint) coating immediately after it has been applied to a surface. This measurement helps ensure that the coating is applied evenly and at the correct thickness to achieve the desired finish and performance.

How it works:

– Notched or Toothed Design: the gauge has notches or teeth on its sides, similar to a comb.

– Measurement: You press the notched or toothed side of the gauge into the wet coating until it touches the substrate (the surface being coated).

– Reading: You then read the gauge to determine the wet film thickness based on which notches or teeth are covered by the coating.

Using a wet film thickness gauge helps avoid applying too much or too little coating, which can affect the quality and durability of the finish.
