When performing maintenance painting of tank coatings, what are the pros and cons of overcoating an existing lining that appears to be in good condition?


Selected Answers

From Jaime Marcos of Profesional independiente on September 15, 2020:
Pros: Execution period (entry into service in a short time). Reduced cost. Valid for tanks with little responsibility. Cons: There may be undetected areas with poor adherence. The detachment of the paint layer, in addition to corrosion, can lead to load contamination. Corrosion spots that have not come to the surface of the coating. Other faults in the coating not visible to the naked eye. The quality of the coating cannot be assured. If the contents of the tank are responsible, the interior lining must be done completely again (blast cleaning and application of the paint system).
