One of the best ways to prevent mold is to control moisture. Here are a few tips to help you keep your shed dry and mold-free.

  • Ventilate Your Shed: Make sure your shed is well ventilated. Install a fan in the shed to help circulate air. You can also open the doors and windows when weather permits.
  • Use a Dehumidifier: Another way to control moisture is to use a dehumidifier. This will help to remove moisture from the air, making it less hospitable for mold spores.
  • Fix Leaks: Leaks in the roof or walls of your shed can cause moisture to build up, so be sure to fix any leaks as soon as possible.
  • Clean Up Spills: Spills can also cause moisture to build up, so be sure to clean them up as soon as possible.
  • Store wet items outside: Wet items, such as gardening tools or sports equipment can also cause moisture to build up. So be sure to store them outside of your shed.
  • Keep the area around your shed clean: Mold spores can also come from the outside, so keep the area around your shed clean and free of debris.

Moisture Trap for Shed

A moisture trap for a shed can be made out of a plastic bin, a piece of foam insulation, and a small fan.

  • The bin should be big enough to fit the foam insulation snugly inside. Make sure there are no gaps around the edges of the bin. The fan should be small enough to fit inside the bin.
  • Cut a hole in the lid of the bin. The hole should be big enough for the fan to fit through.
  • Place the foam insulation inside the bin.
  • Place the fan inside the bin and turn it on.
  • Place the lid on the bin and make sure it is snug. The fan will draw air through the foam insulation and into the bin. The air will be cooled by the foam and will condense on the sides of the bin. This will create a moisture-rich environment perfect for mold spores to thrive.

    Hi, I’m Ricky. I’ve been involved in lawn care and landscaping from when I was 15. To be honest, I didn’t like the idea of pushing mowers, collecting grass clippings, and maintaining flowerbeds at the time. But having seem the passion my parents had for gardening and outdoors and the effort they put in maintaining the health and beauty of our landscape, I couldn’t help but not only admire their hard work but also I became a part of it. As someone who loves to spend time with nature’s best, I find myself learning a lot more about gardening and outdoors on a daily basis. Not to mention I love to share the knowledge I’ve gathered over the years with my readers at We Mow Dallas. To be clear, I don’t have a Master’s degree in gardening or anything like that. Everything I’ve learned about gardening, landscaping, and lawn care spring from passion and engagement with my parents. And with a ton of free information out there, plus the ability to run tests and determine what works best for lawn care and landscaping, every day is an opportunity to learn and implement something new. My goal with We Mow Dallas is to teach you exactly how to maintain your lawn and landscape. And since I walk the talk in reality, you shouldn’t hesitate to join me in this wonderful world of landscaping and lawn care. K Beatrice
