Are untreated pine outdoor ottomans prone to damage from mildew?

Untreated pine outdoor ottomans are indeed susceptible to mildew damage due to their natural porosity and lack of protective coatings. Pine wood absorbs moisture easily, creating an ideal environment for mildew growth, especially in humid or rainy climates. Without proper treatment, prolonged exposure to damp conditions can lead to discoloration, weakening, and even structural damage.

To prevent mildew, consider applying a water-resistant sealant or oil finish to the wood. Regular cleaning and ensuring proper airflow around the ottoman can also help. For long-term durability, storing the ottoman indoors during harsh weather or covering it when not in use is recommended.

If mildew does appear, a mixture of vinegar and water or a specialized wood cleaner can help remove it. Addressing mildew early is key to preserving the ottoman's lifespan and appearance. Investing in treated pine or alternative weather-resistant materials may be a better option for high-moisture environments.
