Road Marking Wet Film Thickness Comb Gauge Set

Stainless steel notched comb gauges and a thermoplastic layer thickness gauge for checking wet film and applied thickness of road marking paint. Used by contractors and highway inspectors during line marking.

Specification

The comb gauge is pressed onto freshly applied paint and the highest notch wetted shows the film thickness in microns, while a hook-type gauge checks hot-applied thermoplastic depth in mm. Correct thickness is essential for marking durability and retroreflectivity. The set is light, rugged and meant for roadside use.
