COATINGSPRO JANUARY 2017 95 Greenfield said the biggest mistake is when people think that "they can change the laws of physics…or at least the outcome of what actions will most likely result in the coating not performing as expected and failing prematurely." He continued, "ere are pretty straightforward processes and directions when applying coatings. If you follow them to the letter, it's typically a success. Otherwise, it's a gamble. ere are a lot of painting contractors that are gamblers." Do you have any particular anecdotes that you'd like to share? "I was hired to perform dry film thick- ness (DFT) measurements on a tank lining that had been applied by a paint- ing contractor," McNeil started. "e specification called for a DFT of 40 to 45 mils [1,016.0‒1,143.0 microns]. W hen I arrived at the site and entered the tank, the painter foreman was present. He informed me that he had measured the DFT with a magnetic pull-off DFT gage (Type 1 according to SSPC-PA-2). He said the DFT was 50 mils [1,270.0 microns] everywhere. I took some measurements with a gage and found the DFT to range from a minimum of 30 mils to a maximum of 48 mils [762.0‒1,218.2 microns]. I asked the painter foreman to take some measurements with his gage and see what we found. He produced his magnetic pull-off gage, and I examined it and found that it would measure 0 to 50 mils [0‒1,270.0 microns]. He said, 'Look at these measurements, and I will show you that it is 50 mils [1,270.0 microns] everywhere.' He placed the gage on the coated surface and turned the wheel forward until it stopped, totally ignoring the magnet. With a scale of 0 to 50 mils [0‒1,270.0 microns], when the wheel stopped it was at 50 mils [1,270.0 microns]. It was obvious that he was not using the gage according to the manufacturer's instructions. W hoever had taught him how to use the gage had given him incorrect information. I proceeded to measure the DFT of the lining with my gage and reported the correct measure- ments to the contractor. is incident is a good example of how things can be done incorrectly if proper training is not received by the operator." Any parting comments for our readers? McNeil and Scisciani left us with thoughts about community and hard work. "I have been in the coatings business for 62 years and have traveled to 26 different countries teaching NACE Coating Inspector Courses and doing consulting, inspection, and failure analysis on coatings," McNeil said. "I have met many different people from many different cultures and have found that the majority of them strive to do the work correctly and try to produce the highest quality results. I have made many friends in these countries and still have contact with many of them. I have been very fortu- nate to have been associated with NACE International for the past 23 years and thank everyone who has made it a great experience for me." "e most satisfying reward in this industry is to make a difference through your work," Scisciani said. "So when you walk away from an applica- tion," he said you should ask yourself, "'Have you made a significant improve- ment?'"
