COATINGSPRO MARCH 2016 53 inert corrosion cells, he said. Tey used abrasive blasting and were able to stay on schedule. Admirable Report Sanchez's process was to do ultra-high pressure water jetting using Jetstream of Houston equipment to remove any salts from the substrate. Next, he followed that up with steel shot blasting using centrifugal Blastrac and GOFF equipment. "Tis method is the most efcient and expedient way to adhere to the ship's schedule," he said. Next, Sanchez was ready for the non-skid coating to be applied, but there was an important step he had to take frst. "No application could be started until we briefed a one-star admiral," he said. Tis sounds like an intimidating prospect, but Sanchez had done his homework. He had prepared a report on the blasting techniques and recommended coating system, and he planned on having the blasting approved at each step in the process. "Ever y three to four days would be blasting and surface prep, then on the fourth or fifth day we would call for a check- point to the government, then the coating system would Then came American Safety Technologies' MS-440G Non-Skid coating, applied using coating hard phenolic rollers at a spread rate of 18–30 square feet (1.7–2.8 m²) for 1 gallon (3.8 L).
