Crown-Molding adds a architectural element of style to a room and is a very popular decorating choice in homes. Crown-Molding comes in a variety of styles and is made from a few different types of materials. Hardwood Crown-Molding is by far the most popular choice. Hardwood Crown-Moldings are available in many wood choices such as cherry Crown-Molding, oak Crown-Molding and maple Crown-Molding, just to name a few. Crown-Moldings are also available in plastic and foam which are gaining popularity because of their price and lightweight design. Crown-Molding installation is definitely a two person job.
Measure all walls of your room and add all of the measurements together to determine how many running feet of Crown-Molding you will need. Add 5% to 10% on to the total for waste and overage.
Always begin Crown-Molding installation on the walls with outside corners. Outside corners are the corners of a wall that jut out into the room.
Determine the angle at the corners of the 2 piece of Crown-Molding that will meet by using a framing square. If you are not familiar with the use of a framing square, you can try a second less precise method for cutting outside corners: Place the Crown-Molding flat against the wall and extending approximately 2 inches past the edge, use a pencil to mark the spot, draw the mark angling from the outside corner towards an inside corner. Use a miter box and saw or a miter saw to cut a 90° angle on the marking. TIP: Always cut outside corners with the Crown-Molding facing upside down. The angle most likely will not be a 90° angle because corners are hardly ever perfect, but it gives you a starting point. Do the same with the other piece of molding that will be used to form the corner. Put the 2 pieces together to form the corner, if it is close leave it! If it is off by a lot, slowly trim the angle with a coping saw.
Cut inside corners in much the same way, but use a coping saw rather than a miter saw. If the cuts are close leave the angles. If the angles aren't close slowly trim them back little by little with your coping saw. If you do not know how to use a framing square, the best you can do it trial and error. Close really is ok, it will not be noticed in the end.
Find your studs up near the ceiling and mark them. Hardwood Crown-Moldings need to be fastened to studs because they are too heavy to be supported by just drywall.
Measure and mark the areas where the studs will be located on your Crown-Molding.
Drill pilot holes into the Crown-Molding. Drilling pilot holes will stop the wood from cracking or splitting when driving in nails.
Nail the Crown-Molding in place into the studs. Place wood glue on the ends to glue joints together and add strength to the Crown-Moldings. Do not attempt to close gaps in corners by nailing because you will split and/or break the molding.
After your Crown-Molding is installed, look for gaps between corners and between the molding and the wall.
Fill the gaps with paintable silicone caulk. Smooth caulking flush with the Crown-Molding.
Painted Crown-Molding is much more forgiving than stained molding. You can hide many defects and ill fitting pieces with caulk and paint.
Installing Crown-Molding is not an easy do it yourself project. Crown-Molding installation is probably one of the most challenging carpentry projects you will encounter, but with time an patience, you can be successful.
