If your urban balcony, patio, or courtyard gets a lot of shade, you've likely asked this very question. The short answer is yes, mildew can be a problem for outdoor furniture in shady spaces, but it is a manageable one. Shade creates a cool, damp, and poorly ventilated environment—the perfect conditions for mildew and mold to thrive. However, by choosing the right materials and performing simple, consistent maintenance, you can keep your furniture looking beautiful.
The key to success starts with your choice of furniture. Some materials are naturally more resistant to moisture and mildew.
* Synthetic Wicker (All-Weather Resin): This is a top contender for shady areas. It is designed to withstand the elements, is non-porous, and dries quickly, making it highly resistant to mildew.
* Metals (Aluminum & Stainless Steel): These metals are excellent choices as they will not rot or mildew. Be sure they have a powder-coated finish to prevent rust.
* Marine-Grade Polymer Lumber (e.g., Trex®): This high-density plastic lumber is incredibly durable and moisture-resistant, making it virtually impervious to mildew.
* Teak: Naturally occurring oils make teak highly resistant to moisture, rot, and mildew. While it will weather to a silvery-gray patina, it remains structurally sound.
Materials to be cautious of in deep shade include fabric cushions and solid wood that isn't teak. Always look for cushions with quick-dry foam and solution-dyed acrylic fabric, which are much more mildew-resistant.
Prevention is your most powerful tool. Follow these simple habits to protect your investment:
1. Use Furniture Covers: High-quality, breathable furniture covers are essential. They protect from dew and rain while allowing moisture to escape, preventing it from being trapped underneath.
2. Provide Airflow: Whenever possible, rearrange your furniture occasionally to promote air circulation. Avoid pushing pieces directly against walls.
3. Clean Regularly: Wipe down your furniture every few weeks with a mild soap and water solution. This removes the organic dirt and pollen that mildew feeds on.
4. Dry Cushions Promptly: After rain or a heavy dew, wipe down furniture and stand cushions on their sides to allow both sides to air dry completely before placing them back.
If you do spot mildew, act quickly. Create a cleaning solution of one part white vinegar to one part warm water. Apply it to the affected area, let it sit for 10 minutes, then scrub gently with a soft-bristled brush and rinse thoroughly. For tougher cases, a solution of one cup of bleach mixed with a gallon of water can be used, but always test it on a small, hidden area first to ensure it does not damage the finish.
In conclusion, while a shady space presents a challenge for outdoor furniture, mildew does not have to be a permanent problem. By selecting mildew-resistant materials and incorporating a simple routine of covering, cleaning, and promoting airflow, you can create a durable and stylish outdoor oasis, even in the shadiest of urban retreats.
