Hi SteveMidwest,
Thank you for your review. I'm sorry to hear about the mold growth in your bathroom! Our Premium Plus Interior paint line is mold and mildew resistant, however, it will not prevent mold from growing completely, especially in high moisture areas. To remove any mold growth in the future, we recommend using a mold/mildew remover (available at your local Home Depot). If the remover discolors the surface, we recommend touching up with more paint for a uniform finish. For further assistance with your project, please feel free to reach out to us directly. We'd be happy to help - Sara
