We also performed relative humidity (RH) tests in the kitchen and operating rooms—they needed to be at 75 percent RH or lower to begin epoxy installation. The levels at this project were up in the 90 percent ratios and the calcium chloride readings were well over the manufacturer's acceptable levels."
