Install Completed Trim on Deck Stairs

What happens here

Once the mitered corner trim piece is fully assembled and the adhesive has cured sufficiently to provide initial strength, transport it to the deck stairs where it will be installed. Carefully position the trim piece onto the stair tread, ensuring it fits snugly and aligns correctly with the existing decking. Secure the trim piece in place using appropriate decking screws or hidden fasteners, driving them into the stair frame or support structure. The completed trim provides a clean, finished look to the deck stairs.
