Gel Coat Thickness Gauge

What Is the #122-A Gel Coat Thickness Gauge?

The #122-A Gel Coat Thickness Gauge is a wet film comb for measuring gel coat thickness during application.

Gel Coat Thickness Gauge reads in both mil scale (1 to 80 mils) and microns (25 to 2032 microns), making it the simplest accurate way to confirm you are laying down the right amount of gel coat for repeatable, high-quality results.

Why Choose the #122-A Gel Coat Thickness Gauge?

Gel coat performance depends on hitting the right film build, typically 20 to 25 mils. Coats that are too thin fail to protect, and coats that are too thick can cause cure problems.

The #122-A Gel Coat Thickness Gauge removes the guesswork with a quick reading in the wet film, so you can build to the target thickness consistently across a part and from part to part.

What Are the Best Applications for the #122-A Gel Coat Thickness Gauge?

The #122-A Gel Coat Thickness Gauge is a core quality-control tool for any gel coat work, used whenever you need to verify wet film thickness, including building tooling gel coat or color gel coat to the recommended 20 to 25 mils.

How Should the #122-A Gel Coat Thickness Gauge Be Used for Best Results?

The #122-A Gel Coat Thickness Gauge is placed edge-first into the wet film. The last tooth marked by the gel coat indicates the wet film thickness. Read in mils or microns and add or reduce coats to reach the target build.
