I cannot make a definite statement on the endurance of the material. However, Milos Green Limestone is usually recommended for indoor installations or as a decorative stone. It is possible to use the limestone for exterior applications in sunny climates, but it may not perform as well as other more durable materials, especially in humid conditions. It is always wise to consult with a stone supplier or a professional architect to determine the viability of using any stone for a particular application.
