Calacatta Ceramic may not be the best choice for outdoor use. Ceramic tiles are generally more suitable for indoor applications due to their susceptibility to weathering and damage from exposure to the elements. Outdoor conditions, such as extreme temperatures, moisture, and UV radiation, can cause ceramic tiles to fade, crack or become discolored over time. Additionally, the smooth and polished finish of Calacatta Ceramic makes it more prone to becoming slippery when wet, which can be unsafe in outdoor environments. It is recommended to consult with a professional or tile manufacturer for specific recommendations on suitable materials for outdoor use.
