Description
The TQC Sheen Wet Film Thickness Gauge – Stainless Steel is a precision comb designed to measure the thickness of wet coatings directly after application. This enables immediate process control and ensures coatings meet specification before curing.
The gauge features a hexagonal or octagonal design with precision-cut notches, allowing quick and reliable thickness determination across a wide measurement range. Manufactured from high-grade stainless steel, it offers excellent durability and resistance to solvents, acids and other aggressive substances commonly found in coating environments.
Available in multiple versions, the gauge is suitable for a broad range of applications—from thin decorative coatings to extremely thick industrial systems such as fireproofing or heavy-duty protective coatings.

Why Wet Film Thickness Measurement Matters
Measuring wet film thickness during application is essential for maintaining coating quality and avoiding costly rework. It allows users to:
- Verify correct coating build immediately
- Predict final dry film thickness
- Prevent under- or over-application
- Ensure coating performance and durability
- Reduce material waste and inspection failures
⸻
How It Works
- Apply the coating evenly onto the test panel or substrate.
- Place the wet film thickness gauge perpendicular onto the wet coating.
- Ensure the teeth make full contact with the surface.
- Remove the gauge carefully.
- Identify the highest wetted tooth and the lowest dry tooth.
- The wet film thickness lies between these two values.
- Clean the gauge after use to maintain accuracy.
