Hey Fred ,

As you are aware, limestone runs a wide spectrum on various geological scales and classifications ; but generally speaking- it has been used continuously for pavements and architectural details for thousands of years with good success.
It is sensitive to acids and mechanical degradation- and like marble it can be
Coated , Vitrified , honed , antiqued, polished and restored when any or all aforementioned finishes fail . It can also be left to its own devices and allowed to
Patina ... thousands of ruins remain the world over to testify that it works as an exterior stone in every imaginable application .
Domestically, Indiana Limestone is the natural choice many specifiers turn to ...I also see thermal finished Bluestone as an interesting and perhaps more durable alternative.

Like CX... I’m curious too : is this a trick question ?😉
