"We had no major concerns going into the job," Clemente said. "Te size of it required a lot of coordination to hit the timeframe, but it was not particularly difcult to do." Te foor showed cracking, spalling, and other areas that needed mortar, and his crew was eager to get started, but Spectrum couldn't get clearance from NYEDC to start. Te paperwork holdup dragged for days and then days became weeks. Hey! How can you make a deadline if you can't start the project? "Due to a paperwork shuffle, we were pushed back to a later start date," Clemente said. "We had to compress our job into a much shorter timeframe, and the only solution was to bring in more manpower and work overtime. We basically "I'm in a position to develop leads, but I'm not an installer," said Leiser. "So it's incumbent on me to develop relationships so that when I come upon a project like the cruise terminal, I have the right installers for the right project." 84 JANUARY 2014 COATINGSPROMAG.COM finished the entire project in two weeks. We were originally given five weeks to do it." When approval finally came, the 15-man Spectrum crew got off to a great start by taking only three days to shot blast and grind the substrate to ICRI CSP 3 standards as specified by Dur-A-Flex. But even that Herculean effort was almost torpedoed. Change of Tacks "Our blast crew was well into the job when we were informed that a road opening nearby would essentially land-lock our diesel generators and compressors," Clemente said. "Without access to them, we would essentially be sitting there doing nothing for a week, so the only choice we had was to work an unscheduled Saturday. Fortunately, we had the right equipment to blast and scrape, and the substrate came off pretty good [sic], so we got our gear out of there before they opened up the road on us." Te crew then used Poly-Crete WR to fll cracks and other imperfections. But from there, fooring specs called for a change of tacks. Te 61,000-square-foot (5,667 m²) customs, baggage inspection, and associated areas would receive a diferent series of coatings that would save steps, time, and money. Tis system also featured clear sand and colored epoxy (versus colored sand and clear epoxy) for a more industrial look, according to Leiser. To create this look, the Spectrum crew frst troweled and back-rolled a single coat of Poly-Crete SL self-priming base. Upon the still-wet surface, the crew hand broadcast to rejection Poly-Crete Flintshot, a non-pigmented sand. Te ⅛-inch (0.3 cm) (DFT including sand) course cured, and excess sand was swept and vacuumed. Next the crew applied a 16-mil (406 microns) DFT seal coat of pigmented Dur-A-Glaze Shop Floor epoxy. Tis coat, when cured, was topped by a single 3-mil (76 microns) DFT pass of Armor Top gloss urethane protective coating. After allowing the Armor top to cure 24 hours, the foor was ready to accept cruise ship passengers. Another detail on this project was the hand-stenciled and -painted NY Cruise logo. The lighthouse was installed on the lobby floor and then coated with a primer and urethane topcoat.
