Cutting crown molding outside corners can be a little challenging. For starters, they stick out more than the top and bottom. This means the crown must be measured and cut accurately. Fortunately, there are a few things you can do to make this process easier.
To begin, you’ll want to choose a template that is the proper length. Most crown molding is available in 16-foot lengths. If you’re not sure whether your molding will span the entire wall, measure one corner of the room and transfer the measurement to the flat side of the crown.
You’ll also want to choose a crown with a good spring angle. The spring angle refers to the angle between the back of the crown and the wall when it’s installed. A good angle will allow the crown to stop support material while cutting. Once you have the right angle, you’ll need to set your saw.
To determine the best bevel for the crown, look to the angle chart. It should list the appropriate angle, as well as the bevel and miter angles you’ll need to cut it out. While you’re at it, you’ll want to find a jig to hold the crown in place while you’re cutting.
Next, you’ll need a pair of measuring tools. One is a large protractor. Another is a test block. Both will work, but the test block will help you see what the correct angles are.
Regardless of which tool you choose, you’ll want to be steady and methodical when cutting crown molding. The result will be a piece that looks great. And, most importantly, it will be installed accurately.
In addition to the above tools, you’ll need a powered miter saw. Unlike a coping saw, which cuts wood along a contoured profile, a compound miter saw will mimic the intersection of a wall and ceiling, allowing you to cut any angle.
Crown moulding is often cut with a compound miter saw. However, you can also use a coping saw. Just make sure the blade is not too close to the molding’s exposed face, and that you don’t make any abrupt changes to the bevel angle.
When you’re ready to start your project, take the time to mark your molding to ensure you’ll be able to properly install it. Some people use a crown moulding hanger to assist in this task. Be sure to check the measurements you made earlier, and you’ll be on your way to a beautiful finish.
You’ll also want to be careful to keep the bottom of the crown molding up while you’re cutting it. Otherwise, you could get stuck in a corner. Finally, be sure to adjust the angle of the saw if you need to. If you don’t have a jig, you can place the crown on a sanding board. Using a dowel rod wrapped in 80-grit sandpaper is a good way to file any small curves.
Whether you’re using a coping saw or a miter saw, be sure to cut the crown molding to the right angles. Depending on how you choose to cut it, you may even want to use a paintable caulk to fill in any gaps between the molding and the ceiling.
