How do UV rays impact the color of teak outdoor sofas over time?

Teak outdoor sofas are prized for their durability and natural beauty, but prolonged exposure to UV rays can significantly alter their appearance. Over time, sunlight causes the wood's natural oils to break down, leading to a gradual color change from golden brown to a silvery-gray patina. This process, known as weathering, is a natural reaction to UV radiation and moisture. While some homeowners appreciate the aged look, others prefer to maintain the original hue. Applying teak sealants or oils can slow this process, but regular maintenance is required. Understanding these effects helps in making informed decisions about caring for teak outdoor furniture.
