Name some test that may need to be conducted during surface preparation and coating
operations. Temperature, Relative Humidity, Dew Point, Anchor Profile, Surface
Cleanliness
Name some of the documentation/reports that may be required to be maintained on a coatings
project. Daily, Weekly Summary, Materials Usage Report, Manpower and Equipment,
Non-Conformance, and Conformance.
What are the most important characteristics of a good report? Objective, Accurate, and
Detailed.
What is the Inspector's primary responsibility and what should the Inspector not do as it pertains
to the specifications. The Inspector's primary responsibility as the Inspector is to "enforce"
the specification. The inspector is NOT to make any changes to the specification for any reason.
Industrial and marine coatings are commonly referred to by: Generic resin type
Oil based coatings applied over alkaline surfaces may result in: Saponification
Three (3) types of water-blasting include: • Grit blasting with a shroud
• Sand injected water blast
,• Slurry blast with grit/water mix
The NACE/SSPC Waterjetting Standard is: SSPC/VIS 4 and VIS 7 are visual comparators
to be used with the standard.
In aspects to coating inspection, what are Ultraviolet lights used to detect? Hydrocarbon
contaminants, such as OIL AND GREASE
Define pigment A discrete particulate solid used to impart specific properties to the
coating in the liquid and solid state.
Define Solvents Solvents are added to liquefy the binder and allow for application in a
productive manner.
Define volatility Governs evaporation rate (the speed at which the Solvent leaves the
coating film during and after application).
Sacrificial coatings... Coatings that use a metal that is anodic to steel and corrodes
preferentially
Test for Soluble Salts Contamination Potassium ferricyanide
Bresle Patch
Sleeve Test
, Soluble Salt Meters
Conductivity
Checking Appears as lines or cracks in the coating surface and typically only appears in
the topcoat, cracks rarely go to the substrate.
Alligatoring Appears where a hard, tough coating is applied over a softer extensible
coating. Some thickly applied coatings can alligator when exposed to sun light.
