joists in the walls that the band board
may be attached to.

ous drainage plane. If running lap siding or shingle siding above the band board, a starter strip should be installed first
to maintain the correct siding angle. Small Periodic gaps should be left in the starter strip to provide an escape route for
excess moisture that may drain down behind the siding.
Use bevel-cut splice joints of at least 22.5° to join long lengths of HardieTrim 5/4, 4/4 boards. To attach band board
to the building, drive two recommended fasteners every 16 in. for 4-in. and 6-in. boards. For 8-in. boards, use three
fasteners every 16 in., and use four fasteners every 16 in. for 12-in. boards.
