Installing Corner Trim

• 1). Prepare the miter saw for angled cuts on the molding. Make 45 degree angled cuts using a miter saw. Set the miter saw blade to the left for inside cuts, and to the right for outside corner cuts.
  
  
• 2). Cut the piece that will make the left-hand side of the corner connection with the miter saw blade set to the left and the molding set in the right-side-up position.
  
  
• 3). Cut the piece of molding that will make the right-hand side of the corner connection by placing it on the miter saw table and cutting with the blade at the 45 degree angle to the right.
  
  
• 4). Sand both cuts smooth with fine grade sandpaper.
  
  
• 5). Place the pieces in the corner to make the corner connection, and then mark either piece that may need to be cut to size.
  
  
• 6). Cut either piece that needs to be cut to size.
  
  
• 7). Place the pieces back in their place in the corner connection, and then install them into place using a hammer and finishing nails.
