Coating Inspection

• Coating Thickness Measurement if the main choice is how to measure dry-film build on the relevant substrate.
• Coating Hardness if the requirement is specifically about choosing the right route for pencil-hardness testing on coated surfaces.
• Adhesion Testing if the question is whether pull-off testing is the right route for bond-strength verification.
• Holiday and Pinhole Detection if you need to confirm whether spark or wet-sponge continuity testing fits the coating system.

One check comes before all of these: if the acceptance question is whether the prepared surface is clean enough to coat, a soluble-salt (Bresle) test with the PosiTector SST measures the chloride and salt contamination that would otherwise draw moisture through the finished film and blister it.

The science behind each acceptance check — how thickness, hardness, adhesion and continuity are actually gauged — is covered in Coating Inspection.
