From Bakery bits:
"The very first time that you use your new banneton you can help to condition it by lightly misting it with some ordinary tap water and then dusting your banneton liberally with flour, tipping out the excess. Do this the day before you want to use it. When it comes to using your banneton every day you need to dust it."
