Celeste Argentina Marble is a beautiful and durable marble that is often used for a variety of applications, including exterior uses. However, its suitability for very rainy climates is dependent on several factors, including proper installation and maintenance.

While Celeste Argentina Marble is generally resistant to water and has a low absorption rate, it is still a natural stone and can be affected by harsh weather conditions over time. In very rainy climates, where the marble may be exposed to excessive moisture and precipitation, there are some precautions that should be taken.

It is important to properly seal and treat the marble to enhance its resistance to water and prevent damage from constant exposure to moisture. Regular maintenance, such as cleaning and sealing, is essential to maintain the marbles appearance and durability. Additionally, ensuring proper slope and drainage on the installation site can help to prevent water accumulation, which could potentially cause issues.

Overall, while Celeste Argentina Marble may be suitable for exterior use in very rainy climates, it is important to consult with a professional installer or supplier who can provide specific recommendations based on your location and circumstances.
