I'm planning to put trim boards on the perimeter of the porch flooring I’m working on.
I'm debating whether the corner joints should be butt joints or miter joints. I want it to look nice and minimize the places where rot can get started. I know miters have a tendency to open up, but a butt joint leaves the end gran exposed. Is this joint a good compromise between the two? I figure there room for some dowels or screws to hold it together.
