Coral Black is a non-porous, rock solid stone that is incredibly uniform and inert. It is also extremely resistant to weathering and chemical reactions. The stone is remarkably durable and remains unaffected by extreme temperature changes. It never loses its luster, not even in UV light. There is virtually no water absorption that ensures high stain resistance and low maintenance. It is also highly abrasion resistant and fire and heat resistant. Due to its high compaction and hardness, large slabs are available without fissures and cracks. A combination of the above strong properties makes this stone extremely favorable for exterior use.
