How to Build a Pathway Lamppost

Apply construction adhesive to the back of the first piece of base trim and press it to the lamppost, square end flush with the end of the cladding. Use a pneumatic finishing nailer and 2½-inch-long nails to attach it, then attach the remaining three base pieces in a similar fashion. Use construction adhesive against the post, but apply waterproof carpenter's glue or polyurethane glue to each of the four mitered corner joints. And be sure to nail through the corners, as shown. Sand all surfaces smooth with a random-orbit sander fitted with a 100-grit disk.
