Are untreated pine outdoor ottomans prone to algae growth in damp climates?

Untreated pine outdoor ottomans can indeed be prone to algae growth in damp climates. Pine is a porous wood that absorbs moisture easily, creating an ideal environment for algae and mold to thrive, especially in humid or rainy conditions. Without a protective sealant, the natural fibers of pine remain exposed, allowing algae spores to settle and multiply.

To prevent algae growth, consider applying a water-resistant sealant or outdoor-grade wood stain to your pine ottoman. Regular cleaning with a mild soap solution and ensuring proper air circulation around the furniture can also help. For long-term durability, storing the ottoman in a dry, covered area during prolonged wet weather is advisable.

If algae does appear, a mixture of water and white vinegar or a specialized wood cleaner can remove it without damaging the wood. Taking these precautions will help maintain the appearance and longevity of your untreated pine ottoman in damp climates.
