32 JULY 2016 COATINGSPROMAG.COM added. Te surface prep was done by Nor Cal Industrial Floors out of San Jose, Calif. Because the jobsite was in a food-processing facility, and a new facility at that, there was a lot of expensive equipment to worry about. "We paid a lot of attention to masking all the equipment to make sure the coating would not contaminate anything," Hallack said. "Tey'd just spent $1 million on equip- ment that had not been used yet." Since the equipment was a lready insta l led, there was a lso lots of hand work that had to be done dur ing the sur face prep process around the equipment legs, conveyor lines, and low equipment. Luck i ly, the genera l contractor had his think ing cap on and made a decision that made life much easier for Ha l lack and his crew. " T he genera l contractor is ver y sav v y and pays atten- tion to ex per ience in the f ield," Ha l lack said. " T hey' d raised a crow n of concrete to ma ke sure the legs of the equipment were above g rade. For us, this is heaven, because we don't have to wor r y about the equipment legs, which is where fai lure ta kes place." Once the f loor preparation was f inished, the crew had to do a major sweeping c leanup and vacuum to ma ke sure no dust was lef t on the sur face. T hen they cou ld beg in work on the coating. Non-Skid Assurance Te coatings crew started by making sure all the equipment legs and walls were protected with blue tape, and they reinforced that with duct tape before product application. Ten they flled in all the saw cut joints with a fexible polymer, Euclid Chemical 's Euco QWIKjoint 200. Next, they put down Dex-O- Tex Vapor Control Primer 200, a moisture mitigation system, at an average of 7 mils (177.8 microns). Tey used 18-inch (45.7 cm) rollers for the application. "It's one of the most advanced technologies," Hallack said. And that moisture control is very important to him. "One of the biggest failures of coatings besides preparation is moisture," he said. "A coating can hit the slab, and it's nice and dry, but moisture may be present underneath. You can spend thousands of dollars on a moisture test, but those take three days, and you have to do many over a big square footage." Instead, Hallack has another method he has adopted. "My company and Dex-O-Tex don't waste time with moisture tests. We just automatically use a vapor-controlled primer whether we need it or not," he said. "It provides the client with extra insur- ance that if moisture happens, we are protected." Te crew also broadcast #60 aluminum oxide to provide a non-skid surface fnish. "It adheres to the primer and provides a non-skid surface," Hallack said. "For the client, safety is the number one concern. Water is used to clean foor surfaces, so non-skid is very important." In fact, Hallack went the extra mile to ensure the coating wouldn't create skid concerns. He made a 2-foot-by-2-foot (61.0 cm x 61.0 cm) mockup sample and took it to the client. "Tey put Buttery Floor T h e crew ap p lie d th e f ir s t s te p of th e co atin g , th e Vap o r Co ntro l P r i m e r 200, w i t h r o l le r s to ~7 m i l s (17 7. 8 m i c r o n s). " O n e o f t h e b i g g e s t f a i l u r e s o f c o a t i n g s b e s i d e s p r e p a r a t i o n i s m o i s t u r e ," Hallack explained. Into the primer, the crew broadca st #60 aluminum oxide. This wa s to provide a non-skid sur face finish to the coating system. The crew wa s sure to work all the detail s. T h e c r e w s w e p t o f f a n y e xce s s a g g r e g ate b e f o r e a p p ly i n g t h e top coat: Q uick Gla ze applied at ~9 mil s (228.6 microns). Af ter 24 hours of curing, the crew walked the client s through the projec t to explain proper cleaning.
