Install Baseboards

What happens here

Once the grout is clean and cured, install the baseboards around the perimeter of the room. If using rounded-over edge baseboards, cut the corners at a 22.5-degree angle (22.5-degree bevel, 22.5-degree miter for outside corners, and a coping cut for inside corners, or just miter inside corners at 45 degrees, which the presenter implies with '22.5 and 22.5'). This creates a tight, professional-looking mitered joint. Apply a strong adhesive, like CA glue with an activator (or construction adhesive), to the back of the baseboard and nail it into place using a brad nailer. This completes the flooring project.

Goal: Finish the room by installing new or original baseboards.
