Above Over the primer, the crew spray-applied VersaFlex's AquaVers 405 Potable Water Spray Polyurea in blue. Using a Graco 20/35, they applied the topcoat at 80 mils (2,032 microns) in one coat.

After a rain test, the ZTI crew knew the job was complete. abilities; they had no emergencies to deal with. Something else that had a very important job on this site was the coatings. The primer, which took a day to shoot and then 18 hours to cure, acted as the first half of a system that meets the requirements for drinking water system components. These components are set forth by the American National Standards Institute (ANSI) and NSF International (formerly the National Sanitation Foundation) in standard 61.5. NSF says that "NSF/ANSI Standard 61 addresses crucial aspects of drinking water system components: whether contaminants that leach or migrate from the product/ material into the drinking water are above acceptable levels in finished waters." The citizens of North Lauderdale should be happy to know that their tank was coated with products specifically made for potable water containers, including the topcoat: VersaFlex's AquaVers 405 Potable Water Spray Polyurea. Keough applied the blue-colored polyurea with a Graco 20/35. It was applied at a 1:1 ratio in one coat at 80 mils (2,032 microns). And with the second man in the tank walking behind Keough to pull the steel tape off the top of the walls, their job was coming to a close. long run. For ZTI, it seemed to work quite well at the start of this job, and they're hoping that the success of this project will bring more work in the future. But before they called the job finished, the crew had the treatment plant wait three days before filling the tank back up with water. This experienced coatings crew wanted to let it rain one more time to make sure no leaks came through the coated walls of the tank. Rain was coming, and when a "deluge," as Tanner called it, hit, they knew they'd passed their own test. And that concluded what Keough called a "cut and dry" job. CP A suCCessful reJeCtion Tanner achieved this contract through not-so-conventional methods. When his presentation for another coatings job a year ago with the city of North Lauderdale didn't win, he may have thought he'd permanently lost the chance to work with them. However, the demo that they showed the city must have made an impression because the director of facilities at the plant called Tanner back about a year later requesting he bid on the tank job. "I put some polyurea on one of [the director's] metal tanks as a sample," explained Tanner. "When they tried to take it off about six months later, they damn near had to use dynamite! They couldn't believe its structural strength." Tanner's situation just goes to show that not every "no" has to be forever. Sometimes, a little effort up front can pay off big in the 66 CoatingsPro g July 2013 Vendor teAM 3M Tape manufacturer 2350 Minnehaha Ave. East Maplewood, MN 55119 (888) 364-3577 Sika Corporation Patch and seal manufacturer 201 Polito Ave Lyndhurst, NJ 07071 (201) 933-8800 CTS Cement Manufacturing Corporation Concrete repair manufacturer 11065 Knott Avenue, Suite A Cypress, CA 90630 (800) 929-3030 Titan Tool Inc.
