Hammer Decking Board into Position

What happens here

After the dry-fit, use a hammer to gently tap the composite decking board into its final, snug position. Apply light, even pressure to the board, preferably with a scrap piece of wood as a buffer, to avoid damaging the surface. This ensures that there are no remaining gaps in the mitered joint and the board is fully seated and flush with adjacent surfaces.

Goal: Achieve a tight, gap-free fit for the mitered decking board.
