When one coating specialist wrote in a JPCL article, “I do not advocate the specification of 'sniff tests' because I don’t know how to calibrate a nose,” he was discussing what coating failure phenomenon?


One coating failure type manifests itself by stickiness and discoloration of the paint and in severe cases by complete liquefaction. What is the failure?


Who was the original author of the NACE publication, Corrosion Prevention by Protective Coatings?


True or false: An adhesive failure of a coating layer occurs at the bottom of the layer; a cohesive failure occurs at the top of the layer.


What is the name of the term used to denote the failure of solvent to completely evaporate from a paint film due to inadequate drying conditions and/or recoating too soon?


True or false: Some causes of blistering of concrete floor coatings are air entrapment in pores of the concrete, osmotic pressure and insufficient cleaning of the concrete surface.


True or false: Hackles are a coating failure type associated with resin-rich areas on a substrate where the coating was applied in excessive thickness.


True or false: Photographic standards are sometimes used to assess the degree of cracking of exterior coatings.

True or false: Adhesive and cohesive coating failures present identical physical results.


True or false: Carbon dioxide and chloride ions are two of the most aggressive materials in the environment that can cause deterioration of concrete.


Among the forces that can contribute to water leaks through holes in building envelope materials are mechanical loads from heating and cooling equipment and the stack effect of conditioned air rising or settling. What is a third force?


What is a term used to describe the accelerated oxidation of galvanized steel caused by exposure to relatively high concentrations of moisture and oxygen trapped between pieces or sheets of steel that are closely stacked?


True or false: When soluble alkali ions react with chemically active forms of silica in concrete, the concrete deteriorates.


True or false: Cohesive and adhesive paint failures are identical in their manifestations.


True or false: A bug hole is an irregular cavity in a wood substrate.


True or false: Carbamation is a form of concrete deterioration.


True or false: Osmotic blistering of coatings on steel substrates can be caused by chloride contamination on the steel prior to painting.


True or false: If there are non-burst blisters in a tank lining, the lining must be immediately replaced.


When the recently deceased Mark Schilling wrote in a JPCL article, “I do not advocate the specification of 'sniff tests' because I don’t know how to calibrate a nose,” he was discussing what coating failure phenomenon?


True or false: “Solvent pop” occurs because of hackles in a steel substrate.


True or false: Oil contamination of the atomizing air in an air spray system can cause fish eyes in the coating film.


True or false: Solvent entrapment within a coating can cause the formation of blisters.


True or false: Osmotic blisters are likely to be filled with liquids that contain solvents or salts.


What kind of corrosion is caused by the formation and collapse of bubbles?


True or false: Non-osmotic blisters can develop in coatings on concrete floors.


Retained water-soluble solvents within a coating film in immersion or continuous high moisture service will, most likely, lead to what kind of failure?


What is a common term for osmotic blistering of coatings due to thermal gradients?


True or false: In coating and surfacing work, bug holes are small cavities in wood substrate caused by insects.


True or False: Peeling, flaking, and delamination are examples of cohesive paint failures.


What does the coating failure term “crazing” mean?


Where does a cohesive failure of a coating occur?


Which of the following coating failure types is an instance of a vertical cohesive failure?


Where does a cohesive coating failure occur?


If a coating failed prematurely because it was formulated improperly, what kind of record would help an applicator defend himself?


True or False: Outside conditions can contribute to coating failure inside a structure.


True or false: Studies about coating failures universally agree that mistakes in contractors’ workmanship cause the majority of failures.


True or false: One study found that engineer/specifiers were as much to blame as painting contractors for coating failures.


Exceeding a recoat window would most likely lead to what type of coating failure?


Which of the following is a possible cause for delamination of a coating?


True or false: When a coating is applied to a wood surface degraded by exposure to sunlight, the coating can fail because of the weakness in the surface layer.


What does the coating failure term "crazing" mean?

Which of the following is a likely cause of blistering of coatings?
