Urban outdoor furniture faces constant exposure to moisture, humidity, and temperature changes - ideal conditions for mold and mildew growth. The resistance of wood to these fungal issues depends primarily on the wood species and protective treatments used. Naturally resistant woods like teak, cedar, and eucalyptus contain organic oils and tannins that create inherent protection against moisture-related damage. For other wood types, pressure treatment with preservatives creates a barrier against fungal growth.
Most quality urban outdoor furniture incorporates either naturally resistant woods or commercially treated lumber that undergoes a preservation process to resist moisture absorption. This treatment forces protective chemicals deep into the wood fibers, creating long-lasting resistance to mold, mildew, and rot. The level of protection varies by product, with higher-grade treatments offering decades of protection.
Regular maintenance including cleaning and occasional resealing further enhances the wood's natural resistance. While no wood is completely impervious to extreme conditions, properly selected and maintained urban outdoor furniture demonstrates exceptional resistance to mold and mildew growth, ensuring both durability and aesthetic appeal in urban environments.
