Wet Film Thickness Gauge

These credit card-sized (2.25″ x 3.25″) inexpensive, lightweight aluminum notch-type gauges contain a silk-screened Belzona logo and web address, and are used to measure the thickness of the wet paint film immediately after application.

When applying a liquid coating, by measuring the uncured film thickness, it is possible to determine the eventual dry film thickness. Applying too much coating wastes time and materials. It can also affect the performance and finish of the product. Too much wet film can cause the coating to crack as it cures; too little coating increases the risk that the substrate will not be sufficiently protected, leading to rust spots.
