What are the differences in porosity between granite and marble outdoor chairs?
When choosing outdoor stone chairs, understanding the porosity of granite and marble is crucial for durability and maintenance. Granite is an igneous rock with low porosity, making it highly resistant to water absorption and weathering. This makes granite outdoor chairs ideal for humid or rainy climates, as they are less likely to stain or crack. Marble, a metamorphic rock, has higher porosity, meaning it absorbs water and is more susceptible to staining and erosion over time. While marble offers elegance, it requires regular sealing to maintain its appearance outdoors. In summary, granite is the more practical choice for long-lasting outdoor furniture, while marble suits those prioritizing aesthetics with extra care.
