Versailles Limestone can be used in exterior applications in humid climates, but it may require additional care and maintenance compared to other limestone varieties. Limestone is a natural stone and is porous, which means it can absorb moisture. In humid climates, there is a higher amount of moisture present in the air, and this can potentially lead to issues such as staining, degradation, or discoloration of the limestone.

To protect the Versailles Limestone and ensure its longevity in such climates, it is recommended to properly seal the stone. Sealants help to create a protective barrier on the surface of the limestone, preventing moisture from penetrating into the stone. Regular resealing may be required to maintain this protective layer, especially in highly humid areas.

Additionally, proper installation is crucial to minimize water infiltration. Adequate drainage systems and proper slope should be implemented to prevent water from pooling or accumulating on the limestone surface.

Its also important to note that limestone is characterized by its natural variations in color, texture, and porosity. Some limestone varieties may be more resistant to moisture than others, so its advisable to consult with a professional or supplier familiar with the specific characteristics of the Versailles Limestone before using it in exterior applications in very humid climates.
