preparation and coating operations. Answer: Ambient 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. Answer: Daily/weekly
,summary, material usage reports, manpower and equipment,
conformance, and Non-conformance
◉ What are the most important characteristics of a good report?

application temperatures. Answer: Failure to cure, too rapid solvent
evaporation, poor film formation
◉ Describe relative humidity. Answer: The amount of moisture in
the air compared to saturation level
◉ What is the dew point temperature? Answer: The temperature at
which moisture will begin to form on a steel surface.
◉ Name some of the effects wind may have on a coatings project.
Answer: blowing abrasives, causing excessive drift or overspray,
accelerating solvent evaporation, contributing to the formation of
