Install Composite Skirting, Fascia, and Waterproofing

What happens here

After the hot tub is in place and main support posts are up, the exterior perimeter of the deck's lower sections, particularly around the hot tub, is finished with composite decking skirting and fascia. These darker-colored composite boards are cut to fit and screwed into the framing, creating a clean, aesthetic border and hiding the structural elements below. This step also involves installing a black rubber or waterproof membrane to protect the underlying structure from moisture and provide a clean finish around the hot tub's edge.

Goal: Apply decorative and protective composite skirting and fascia to the deck perimeter and waterproof around the hot tub.
