How does porosity affect granite and marble outdoor flower boxes?
Porosity plays a crucial role in determining the durability and performance of granite and marble outdoor flower boxes. Granite, with its low porosity, is highly resistant to moisture absorption, making it ideal for outdoor use where weather exposure is frequent. It withstands freezing temperatures and rain without cracking or staining. On the other hand, marble has higher porosity, absorbing water more easily, which can lead to discoloration, cracking in cold climates, and faster wear over time. For long-lasting outdoor flower boxes, granite is the superior choice due to its lower porosity and greater resistance to environmental damage. Regular sealing can help marble flower boxes, but granite remains the more reliable option for harsh outdoor conditions.
