What are the risks of using untreated marble in rainy climates?

Using untreated marble in rainy climates can lead to several significant risks. Marble is a porous natural stone, making it highly susceptible to water absorption. In wet environments, prolonged exposure to moisture can cause staining, discoloration, and even structural weakening over time. Acidic rainwater can also react with the calcium carbonate in marble, leading to etching and surface erosion. Additionally, untreated marble may develop mold or mildew in damp conditions, compromising both its appearance and durability. To prevent these issues, proper sealing and regular maintenance are essential for preserving marble surfaces in rainy climates. Investing in protective treatments can significantly extend the lifespan and beauty of marble in such environments.
