Install First Main Trim Section

What happens here

With the trim pieces cut and prepared, carefully lift and position the first main trim section into its designated place on the structure. This often requires two people, especially for longer pieces, to ensure proper alignment and prevent damage. Once the board is correctly aligned, use a pneumatic nail gun to fasten it securely to the underlying framing. Ensure the nails are driven flush with the surface of the trim board, or slightly countersunk.

Goal: Securely attach the initial trim board to the building structure.
