COATINGSPRO NOVEMBER 2017 29 behind vacuuming, getting everything cleaned up — and the hand work, all the tedious hand work that had to be done. And when you're going around very expensive tile already set in place, you've got to be very careful." Luckily, the crew didn't have to go far for rest at the end of the long work days. ey were housed in hotels near the jobsite, and from what Verry said, they didn't have time to enjoy Miami. Instead, they "spent all their time working." After the surface prep was complete, "we then cut out all of the joints and caulked them back in," Verry explained. Cutting and caulking joints is Desco's effort to " keep any cracking from resurfacing as the building moves." According to him, "the number one enemy of our industry are joints. We find on a project like this that we're better to cut and clean the joints out. It gives a rough edge inside of the joint, which allows adherence from the caulk down in, so it grips it. And hopefully you don't see an issue resurfacing." After they applied the polyurea joint caulk by Metzger McGuire, called RS88, the crew was finally able to move on to apply the coating system. Once tiles and columns were protected, the crew moved onto prep, which took 35 hours to complete. That included grinding, blasting, and vacuuming the white concrete, and cutting and caulking joints. Not only did the client want striping for the finished look, but they also wanted 10-foot (3.1 m) long directional arrows. The crew completed these with a template, rolling on the blue and white stripes.
