What happens here
After cutting, apply appropriate adhesives to the mitered edges of the composite decking boards. First, spray a quick-drying adhesive (like a contact cement or primer for composite) to prepare the surface. Then, apply a bead of construction-grade adhesive along the mitered edge of one board. Carefully align and press the two mitered boards together, ensuring a tight and clean joint to form a mitered corner.
Goal: Create strong and seamless mitered corner joints.
