Chinas Stalattite Brown Marble can be used outdoors, but it is important to note that the durability and longevity of the marble may vary depending on the specific climate and environmental conditions. Marble is generally a porous and softer stone compared to other natural stones, such as granite, and it may be prone to weathering and staining over time when exposed to elements like rain, sunlight, and freezing temperatures. Therefore, it is recommended to properly seal and maintain the marble surface regularly to protect it from potential damage. Additionally, it may be advisable to consult with a professional in the stone industry or a supplier familiar with the specific characteristics of Chinas Stalattite Brown Marble for more accurate guidance and recommendations on its outdoor use.
