Floating Roof Storage Tank Coated with Dry Fall Coatings

CITGO installed a new 48’ floating roof petroleum storage tank at their facility in Victoria, Texas and contracted West Virginia Paint, LLC to paint it. CITGO’s primary concern was for high performance protection for the tank and maximum performance and duration of the coating system. With regard to application, there was also a major concern about paint overspray damage to the Chrysler Dodge Car Dealership just 200 feet away from the new tank. Because of the proximity of the car dealership to the new tank, even brush and roll application presented a great risk for airborne paint droplets to damage the new cars. To avoid encapsulation procedures and extended application time, CITGO decided to use Highland solvent borne dry fall coatings to satisfy both of these concerns. A dry fall 3 coat system of 325R Zinc Rich Epoxy Primer, 475R Epoxy Primer (mid-coat) and 68R Urethane Topcoat was used to provide the level of protection required. The project began in December, and winter weather also presented potential application problems:
Mean Temperature – 43.1˚F, Surface Temperature – 40˚F, Mean Wind Speed – 16.46 mph with gusts up to 28 mph
