Crown molding is used at the joint of the ceiling and walls to create a more polished appearance. Crown moldings are commonly seen in new homes in the living room areas as well as the den or library, but can be installed in any room of the home with a few tools and a little time.
You will need:
Step 1: Make a guide fence by putting a piece of molding at an upside down angle on the miter saw table. The narrow bevel on the back should rest on the saw table, since this is actually the top of the molding. The wide bevel should be against the saw’s vertical fence and secured in place with clamps. Cut a piece of wood that is 30 inches long to use as a fence.
Step 2: Put hot glue on either side of the rotating center of the saw table, and push the fence into place against your clamped molding. Remove the crown and then cut the center section of the fence at a 45 degree angle in each direction. When working counterclockwise in a room, adjust the saw for a 45 degree miter cut to the left side. Place each piece of molding that will be at a corner on the saw as in step 1, and complete the cuts on either end of the molding.
Step 3: Apply thin layers of glue to the scarf joint on the molding and then nail into place using a hammer and nail. Use the nail set to push the nails just below the surface of the molding for a smoother look. Install the next piece of crown molding so that it creates a tight joint, but does not overlap.
Step 4: Go around the room in a counterclockwise manner so that each piece of molding you cut earlier fits in the exact order you cut it. Place a small line of hot glue along the edges or joints of the molding and then nail into place. Use the nail set to gently set the nail heads beneath the surface of the molding.
Step 5: Place wood putty on the end of your finger and push gently into the holes left by the nails you pressed in with the nail set. Wipe surface with your finger to allow all holes to be even with the surface of the molding. Allow this to dry for at least 40 minutes prior to painting.
