Enviro Wet Film Thickness Gauge

To measure the wet film thickness during application, a wet film thickness gauge (also known a wet film comb) is often used. It is a very simple and quick tool for measuring the film thickness of wet paint.

A wet film comb is a rectangular piece of metal or plastic with “teeth” of various lengths, each representing a different film thickness. The longest teeth are at the top and bottom of each side of the rectangle.
