How to Install Crown Molding

Installing Crown Molding by HomeAdditionPlus.com Hi! I am Mark Donovan from HomeAdditionPlus.com, and today we are going to show you a few examples of crown molding and some tips on how to install. What you are looking at here is an example of dentil crown molding. To minimize placing, boxes have been inserted in the mid point between the walls. Because the fact that walls are typically not straight or 90 degrees to each other, boxes have also been used in the corners in this example to help ease the displacing and again reduce the signs of displacing between the two intersections of the walls. In this example of crown molding in the dinning room, you can see there are inside corners and outside corners that have been formed using boxes again to minimize displacing where the effects or visual effects of displacing. In this example, you are seeing a tri-ceiling here, with the basic 3 ½ inch crown molding with the top and bottom under board and again box are used to separate the mid points as well as used them in the corners again to minimizing displacing effect. And what we have here is the hallway where crown molding, it is just now being installed and what you are looking at here is basic crown molding 5 ½ inch crown molding with no boxes or no under boards being used for the installation of this. So this particular crown molding project, we are using 5 ½ inch crown molding, when we selected it, we made sure that was perfectly straight, no twist in it otherwise it will be a very difficult job hanging it, and then we brought it home and let it sit for about 24 to 48 hours to get adjusted to the temperature of the room and the humidity in the room. Then we primed it and we added a sealer color finish painting on it, since we minimize the effort painting once the crown molding is actually installed. To cut Crown molding, it is best to turn it upside down and downwards relative to how he will hang it on the wall, so you can position it nicely up against the sides to make your cut. When making inside corners, you can either do 90-degree corners that is what we have here, or you can do copy cuts as you see here using a coping saw. To make your coping cuts, you take one of the sections of board that has been cut to 45-degree angle and at the bottom and the top you cut a straight perpendicular line to the relief points, first relief points again at the top and the bottom of the crown molding. Once we removed both the top and the bottom wedges, we then take our coping saw and cut along the paint line in a 45-degree angle to basically back cut the crown molding material. Once we have cut the backside of 45-degree angle board, we now have our coped edged. You can now use it to form our inside corner, see. And now we have our finished inside corner cut using the coping technique. The first thing you want to consider when installing crown molding is make sure you nail onto nail points, that means the stud wall along the walls and the ceiling joints or strapping on the ceiling. For this particular crown molding which is 5 ½ inch crown molding, we need to draw a four-inch line coming down from the ceiling all around the length of the wall. I am going to score that line and make that line again traverse to the entire length of the wall. We do this to ensure that the crown molding is straight along the wall and the ceiling. The next important thing to remember is that you need to apply wood glue to all joints before installing them on the wall. This helps to make sure that there is not separation between the sections of wood at the joint. When installing crown molding, it is important to use a finish nail gun. So, now that we have completed the first section of crown molding, we move on to the next portion. One of the most difficult sections of crown molding to install is the double edged coped cut. Once you have fastened the crown molding to the walls and ceiling, you need to fill out the nail holes and the seams with wood filler. For the edges of the crown molding, you want to apply a silicon coat along the wall and the bottom edge of the crown molding and along the ceiling and the top of the crown molding. After applying a bit of coat, you use a wet rug to clean up the ceiling. Now just touch up the crown molding with little paint, and your crown molding project is done. So, those are some styles and tips for installing crown molding. Crown molding can really dress up that appearance of a room.
