If you have a north-facing patio that receives minimal direct sunlight, selecting the right furniture material is crucial to prevent mildew and mold growth. Dampness and shade create a perfect environment for these issues. The best materials for this challenging urban environment are those that dry quickly, are naturally resistant to moisture, or are non-porous.
Aluminum is a top choice for shady patios. It is rust-proof, durable, and its non-porous surface means water beads up and evaporates quickly, leaving no opportunity for mildew to take hold. Powder-coated aluminum offers even greater protection and comes in numerous styles.
Synthetic resin wicker, typically made from high-density polyethylene (HDPE), is another excellent option. This material is designed to withstand the elements. It is waterproof and easy to clean—simply wiping it down is often sufficient to prevent any mildew buildup.
While wood can be susceptible to moisture, teak stands apart. Its high natural oil content makes it inherently resistant to water and decay. If left untreated, teak will weather to a elegant silvery-gray patina without rotting. Other woods like eucalyptus can be suitable if they are properly sealed and maintained with annual oiling.
To further prevent mildew on any furniture, choose quick-drying cushions made with Sunbrella or similar solution-dyed acrylic fabrics. These fabrics are designed to resist moisture and mildew. Additionally, arranging your furniture to allow for maximum air circulation and occasionally wiping down surfaces after rain will help keep your shady patio fresh and mildew-free.
