What is the table’s resistance to discoloration from prolonged exposure to sunlight?

When evaluating furniture for outdoor or sunlit indoor spaces, a critical question arises: What is the table’s resistance to discoloration from prolonged exposure to sunlight? This resistance, fundamentally, is the material's ability to maintain its original color and finish when subjected to ultraviolet (UV) radiation and solar heat over time.

The primary cause of discoloration is photodegradation, where UV rays break down chemical bonds in pigments, paints, and the material itself. Resistance varies dramatically by material. Natural woods like teak and cedar contain oils that offer moderate inherent resistance but often weather to a silvery-gray patina. Powder-coated aluminum and metals with quality finishes provide high resistance through a protective barrier. All-weather wickers made from UV-stabilized synthetic resins are engineered for excellent colorfastness. Glass and stone are highly resistant but are not immune to associated issues like glue or sealant degradation.

Key factors determining resistance include the quality of UV inhibitors integrated into materials or topcoats, the density and type of pigments used (ceramic or acrylic pigments often outperform standard ones), and the presence of a protective clear coat or laminate. Regular maintenance, such as applying UV-blocking sealants on wood or protective wax on metal, significantly enhances longevity.

To choose a sun-resistant table, look for specifications mentioning "UV-resistant," "colorfast," or "outdoor-rated." Understand that some materials, like certain plastics or low-quality paints, may fade or chalk quickly. Ultimately, a table's resistance to sun discoloration is a direct result of its material science, manufacturing quality, and proactive care, ensuring it remains visually appealing for years despite daily solar exposure.
