Is it necessary to holiday test the interior lining in the vapor phase (roof) of water storage tanks after coating?


What are the benefits and risks of using holiday testing on mat-reinforced, thermoset linings (over a conductive primer) on concrete substrates intended for immersion service? Should other tests be performed with or instead of holiday testing?


What is the maximum number of holidays that should be permitted for linings used in immersion service, and why?

What is the risk of damaging a paint film by inspecting a repaired area more than twice with a high-voltage holiday detector?


For coatings with a high-solids content (95 percent or more), what kinds of defects, such as holidays or micropores, are possible or likely to occur in the applied film? How can these be prevented or remedied?
