What happens here
The video begins by showing two composite decking boards, already cut at a precise mitered angle (typically 45 degrees for a 90-degree corner), positioned on a deck frame. Beneath the decking, a black 'System Flashing Tape' is visible, protecting the joists. The two mitered ends of the decking boards are initially placed with a small, visible gap between them. Screws are already used to secure other parts of the decking, but the focus is on fitting this specific joint.
Goal: Set up the mitered decking boards with a slight gap to allow for a compression fit.
