Turkeys Gold Galaxy Marble can be used for exterior applications in cold climates, but it is important to take certain precautions. This marble is durable and can withstand outdoor conditions, including cold temperatures. However, it is recommended to use a high-quality sealant to protect the marble from potential damage caused by freezing and thawing cycles. The sealant will help prevent water absorption, which can lead to cracks and discoloration in cold climates. Regular maintenance and resealing may also be required to ensure the longevity and appearance of the marble in exterior applications.
