Can China's Caihui Marble be used outdoors?
I dont have enough information to determine the exact characteristics of Caihui Marble, such as its grade, size, finish, and porosity. However, generally speaking, Marble is not recommended for outdoor use because it is vulnerable to weathering, staining, and fading due to exposure to sunlight, moisture, and chemicals. Instead, it is better suited for indoor applications such as flooring, walls, countertops, and decorative features. If you want a natural stone material that can withstand the rigors of outdoor environments, you may consider using granite, limestone, sandstone, or slate, which are more durable and resistant to the elements. It is advisable to consult with a professional stonemason or supplier to determine the most suitable material for your specific needs and climate.
