How do WPC and resin compare in resisting bird droppings or sap stains?

When it comes to outdoor materials, resistance to environmental factors like bird droppings and sap stains is crucial for maintaining appearance and durability. WPC (Wood Plastic Composite) and resin are two popular choices, but how do they compare in this regard?

WPC is known for its durability and low maintenance. Its non-porous surface makes it resistant to stains, including bird droppings and sap. Cleaning is straightforward, often requiring just soap and water. However, prolonged exposure to acidic substances like bird droppings may cause slight discoloration over time.

Resin, on the other hand, is highly resistant to stains and chemicals. Its smooth surface prevents substances like sap from penetrating, making it easier to clean. Resin's inherent resistance to UV rays and moisture also helps maintain its appearance, even under harsh conditions.

In summary, both materials perform well against bird droppings and sap stains, but resin may have a slight edge due to its superior chemical resistance and ease of cleaning. For long-term outdoor use, resin could be the more reliable option.
