This year’s “The International Surface Event,” which now includes Surfaces, StonExpo/Marmomacc Americas and TileExpo, was a very busy show. Not only from the seemingly endless number of exhibitors to see, but also the increasing number of hands-on certification courses on the show floor hosted by groups including International Certified Floorcovering Installers (CFI), the Ceramic Tile Education Foundation (CTEF), and the International Concrete Repair Institute (ICRI). I had the pleasure of being a judge for ICRI’s hands-on certification. You know, it’s difficult enough when having to take a test, but to have to do so in front of so many show attendees adds even more pressure; hats off to those who attended this certification.
Those going through the certification process attended a seminar the day before to gain knowledge about concrete and proper moisture testing procedures following American Standards Testing Methods (ASTM) guidelines. The following day was hands-on testing, including the placement of calcium chloride test kits, relative humidity in-situ tests and hood tests, which measures relative humidity at the surface of a concrete slab.
