44 MAY 2016 COATINGSPROMAG.COM compound as the primer, minus the water but plus aggregate and broadcast sand. "Once you start, you can't stop without creating a seam that you can't really disguise. If you leave a rough spot or miss something, you really can't patch it without having it look like a patch. You're shooting for perfection but it's hard to achieve it." To give DCV the best chance at hitting perfection, Seay organized his 12-man crew by numbers. Crewman number one premixed the 3460B (hardener). Number two measured the 3460B. Tree measured the 3460A (resin). A fourth man mixed hardeners and resins while a ffth poured the mixtures into 10-gallon (37.9 L) tote buckets. Number six blended GP 5150 aggregate to the mix. Crewman seven carted buckets to the work area. Trent, eighth in line, spread the material with a ¼-inch (0.64 cm) notched squeegee. A ninth man backrolled with an 18-inch (45.7 cm) loop roller. Seay and partner Landon Blanks (numbers 10 and 11) donned spiked shoes and hand broadcast GP 5310 sand to the point of rejection. Te 12 th man flled and fed sand buckets to Seay and Blanks. At the end of a very long day, the crew had covered all 9,000 square feet (836.1 m²). To a man, they knew that the quality of the slurry coat would dictate the quality of the metallic coat they'd install the next day. As they headed home, they wondered how they had done. Reno Revelation Early the next day, the DCV crew swept and vacuumed all excess sand. Even in the harsh morning light, the slurry coat ofered up no negative revelations. Specs called for the application of a single pass of GP 3579 epoxy primer in gray at an average of 120 square feet per gallon (11.1 m² per 3.8 L). "We prime so the metallic coat doesn't pick up sand," said Seay. "It also helps smooth the surface so the texture of sand doesn't show through or interfere with the way the metallic coat fows." On spreading the GP 3579 primer, squeegee master Trent advised not to skimp. "You don't want to spread it too thin, so use a light touch," Trent said. "Let the weight of the squeegee do most of the work. Te metallic coat is your money coat, and it fows a lot better if you get your primer down right." After allowing the primer to cure overnight, the crew arrived the next day, ready to apply the metallic coat. Like the slurry coat, once the installation started, there would be no stopping until they covered the entire foor. Just as they were about to begin, a series of loud thumps reverberated throughout the room. Seay raced next door to investigate and couldn't believe his eyes. Apparently a crew from another trade didn't completely understand the building layout. Te loud thumps were coming from sledge hammers pounding against an adjoining cinder block wall! Had the wall broken through during epoxy installation, the ensuing damage and debris would have set the project back days. Luckily, a few kind words put a stop to the wrecking crew's actions.
