Which statement correctly describes when a visual inspection of TFIFRM should occur?

• A. It can occur anytime during application
• B. It must occur before drying
• C. It can occur after drying or curing
• D. It must occur before surface prep

Answer: (C)

Visual inspection is most meaningful once the TFIFRM coating has dried or cured because the film has reached its final state. At that point, the surface appearance, thickness uniformity, color, and adhesion can be accurately assessed. Inspecting while the material is still wet or still drying can hide or distort defects like runs, sags, pinholes, or uneven thickness, leading to an inaccurate evaluation. After drying or curing, you can confirm that the finish is uniform, intact, and meets the required criteria, and determine if any repairs are needed before the system is put into service.
