Can polished marble surfaces on outdoor sofas resist rain and humidity?

Polished marble surfaces on outdoor sofas offer elegance and durability, but their resistance to rain and humidity depends on proper maintenance. While marble is naturally porous, polished finishes provide some protection against moisture. However, prolonged exposure to rain and high humidity can lead to staining, etching, or even cracking over time.

To enhance resistance, apply a high-quality sealant designed for outdoor marble. Regular cleaning with pH-neutral products and immediate drying after rain exposure will help preserve the surface. For long-term durability, consider covering the sofa during heavy rainfall or storing it in a sheltered area during humid seasons.

In summary, polished marble can resist rain and humidity to some extent, but proactive care is essential to maintain its beauty and functionality outdoors.
