In this tutorial, we learn how to install crown molding to your room. First, choose the right size and style of molding for the room, then measure your room to find out how much you need. After this, you will need to buy a saw to cut the molding when you're ready to install. After you have the pieces cut, you will need to place these against the wall and then nail them in with a nail gun. Secure the molding to the joints in the ceiling and to the studs in the wall. To finish, putty the holes and paint the molding to match the ceiling.
