I just opened my pail of drywall mud and discovered mold on the sides. It has been a few months since I last opened it. This happened to me a few years ago. I tried using the mud anyway, but the bad odor persisted in the dried mud. I had to toss that pail of mud. As a work-around, I've been using 20 minute mud powder, but that was going to be inconvenient for a somewhat larger project I had recently. How do I prevent mold from growing in the bucket?
Edit: I wonder if I sprayed (light mist) a mix of chlorine (Clorox) and water onto the sides and surface of the mud?
