The University of Minnesota selected Classic Protective Coatings to perform the rehabilitation of the existing St. Paul Water Tower in Minneapolis, Minnesota.
Scope of Work consisted of coating and repairing an existing 150,000-gallon elevated spheroid water storage tank.
Classic Protective Coatings abrasive blast-cleaned the wet interior tank surfaces to Near White standards SSPC-SP10. The interior wet surfaces will then be coated with a zinc-rich primer and two-coat epoxy system.
The interior dry surfaces were abrasive blast-cleaned to Commercial standards SSPC-SP6 and coated with an epoxy system in the control room at the base of the tank. All failed coating in the dry area were spot prepared to an SSPC-SP11 power tool clean and then coated with an epoxy system.
Exterior tank surfaces were abrasive blast-cleaned to Commercial standards SSPC-SP6 and coated with a zinc-rich primer, epoxy intermediate and urethane finish.
Exterior concrete foundation surfaces will be abrasive blast-cleaned to Concrete standards SSPC-SP13 and coated.
Classic Protective Coatings applied a “M” for the logo which symbolized the University of Minnesota logo.
Due to the tight sight we used Class 1A full containment with a bonnet to ensure no emission escaped and surrounding buildings, people and vehicle did not incur any dust debris or paint damage.
