How to remove mold from wood terraces / wooden decks

Mold growth on wooden decks is a common problem that can be unsightly and potentially harmful to the health of you and your family. Fortunately, there are several ways to effectively remove mold from wooden decks, using both natural and chemical methods.

First, it is important to identify the type of mold that is growing on your deck. Black mold, for example, is a type of mold that is particularly dangerous and should be handled with extreme care. Other types of mold, such as mildew, are less harmful but can still cause damage to your deck if left untreated.

What do you need to remove mold from a wooden deck?

To remove mold from a wooden deck, you will need to gather some supplies. This may include a bucket of warm water, a long-handled brush or stiff-bristled brush, a garden hose, a spray bottle, and a cleaning solution.

Before you start cleaning, it is important to protect yourself by wearing gloves, goggles, and a dust mask. Additionally, you should clear the area of any furniture or decor to prevent accidental damage.

Step 1: Wet the deck Start by using your garden hose to thoroughly wet the deck. This will help to loosen any dirt or debris and make it easier to remove the mold.

Step 2: Clean the deck Using your long-handled brush or stiff-bristled brush, scrub the deck surface to remove as much mold as possible. Be sure to pay extra attention to any areas that are particularly moldy.

Step 3: Apply a cleaning solution Fill a spray bottle with a cleaning solution specifically designed for removing mold from wood. Some popular options include white vinegar, hydrogen peroxide, and baking soda. Spray the solution generously over the entire deck surface, taking care to saturate any remaining moldy areas.

Step 4: Allow the solution to sit Leave the cleaning solution on the deck for at least 15-20 minutes to allow it to penetrate and effectively remove the mold.

Step 5: Rinse the deck Use your garden hose to rinse the deck thoroughly, removing all traces of the cleaning solution and mold.

Step 6: Dry the deck Allow the deck to dry completely before replacing any furniture or decor.

It’s important to note that if you have a large mold infestation, you may need to repeat the cleaning process several times to completely remove all of the mold. Additionally, if the mold is extensive, it’s best to consult a professional.

How to prevent mold from returning:

  • Keep the deck clean and dry: Regularly cleaning your deck and ensuring that it is properly sealed and maintained can help prevent mold from returning.
  • Remove standing water: Make sure that any standing water is removed from the deck immediately, as this can create the perfect environment for mold to grow.
  • Use a mold-inhibiting finish: Applying a finish that contains mold inhibitors can help to prevent mold from growing on your deck in the future.
  • Keep the deck in the shade: Positioning your deck in a shaded area can help to reduce the amount of moisture that accumulates on the surface, making it less likely for mold to grow.

Removing mold from a wooden deck can be a bit of a hassle, but it is an important step in maintaining the appearance and safety of your outdoor living space. By following the steps outlined above, you can effectively remove mold from your wooden deck and prevent it from returning in the future.
