Calacatta White Porcelain is not typically recommended for outdoor use. Porcelain tiles are more commonly used for indoor applications such as flooring, walls, and countertops. Outdoor environments can expose the tiles to harsh weather conditions, UV exposure, and potential damage from freeze-thaw cycles. These factors can lead to cracking, fading, and overall deterioration of the tiles. It is best to consult with a professional or the manufacturer for specific recommendations regarding the use of Calacatta White Porcelain tiles outdoors.
