Can Greece's Astoria Grey Marble be used exterior applications in very humid climates?
Greeces Astoria Grey Marble is a natural stone that is commonly used for interior applications such as flooring, countertops, and wall cladding. While it can technically be used for exterior applications, there are considerations to keep in mind, especially in very humid climates. Marble, being a porous material, is susceptible to moisture absorption. In very humid climates, the high moisture content in the air can potentially lead to water penetration into the marble, causing it to deteriorate over time. This can result in discoloration, staining, or even cracking. However, if proper precautions are taken, Astoria Grey Marble can still be used in exterior applications in humid climates. These precautions include: 1. Sealant: Apply a high-quality sealant specifically designed for outdoor use on the marble surface. This will help create a barrier, preventing moisture from infiltrating the stone. 2. Regular Maintenance: Regularly clean and maintain the marble to prevent the accumulation of dirt or moisture on the surface. Ensure prompt cleaning of any spills or stains to avoid long-term damage. 3. Shading and Protection: Consider providing shading or protection from direct sunlight, as excessive heat and prolonged exposure to UV radiation can contribute to the deterioration of marble in humid climates. 4. Proper Installation: Ensure that the marble is installed correctly with adequate drainage systems in place. This will help prevent water pooling or stagnation, which can accelerate the deterioration process. It is always recommended to consult with a professional stone supplier or installer who can provide specific guidance based on the local climate and conditions. They will be able to assess the feasibility and suitability of using Astoria Grey Marble in exterior applications in a very humid climate.
