How to Install Baseboards
Add style and a finished look with decorative baseboards.
You can use this technique to match a discontinued design.
Cut the molding to size and position it on the top edge of the molding. Joints may be mitered or butt-joined (as in this sequence).
Secure the molding in place with finish nails. Continue to install the molding along the baseboard.
Fill nail holes and joints, and sand before painting.
