I do not have personal opinions or experiences, but according to the general properties of Calacatta Ivory porcelain, it is suitable for exterior applications in sunny climates. Calacatta Ivory porcelain is known for its high durability and resistance to extreme weather conditions, including UV rays, temperature fluctuations, and moisture. However, it is always recommended to consult with a professional before installing any material in an exterior application to ensure it is suitable for the specific location and conditions.
