We are building a farmhouse-style home with an L-shaped front entry porch and a true screened porch in back. We were considering composite decking until we took a look at stamped concrete and realized it would probably be much cheaper, maintenance-free, and more "permanent"-looking. We want a flagstone look with a rough texture. But I haven't seen examples of it used for porch floors, so I'm wondering if there's some reason to avoid it in that usage. Anyone have experience?
