Ethanol tanks are common in the gas and fuel industry. And painting them is a common maintenance procedure. But commercial painting contractors need to be aware of the fungal growth that’s common with ethanol, and what types of coatings will resist its growth.
Baudoinia compniacensis. You probably don’t know what this is, nor do you know how to pronounce it. But this is a black fungal material that likes to grow on ethanol tanks, distilleries, and your uncle’s old whiskey barrel. But no matter which substrate you’re painting, be sure to have an industrial thermometer handy to get the temperature reading on the surface.
And like most painters, this fungus likes alcohol. So if there’s a business that has holding tanks for ethanol, you can be sure to expect to see this black fungus in a few short months or a few long years.
