How to Cut Crown Molding with a Compound Miter Saw

Crown molding is an elegant and stylish way to finish any room with flair. However, many people shy away from using it because the installation process seems intimidating and complicated. If you want to take your home décor to the next level, you need not fear crown molding. With the aid of a compound miter saw, it is possible to achieve professional-looking results, even for a beginner.

In this article, we will show you how to master the art of cutting crown molding with ease.

Step One: Understanding the Angles

Before you start cutting your crown molding, you need to understand the angles that it consists of. Crown molding has two angles, a spring angle, and a crown angle. The spring angle is the angle between the ceiling and the back of the molding. The crown angle is the cut that needs to be made in the molding itself to fit against the wall and ceiling. These angles can vary depending on the molding you choose. To ensure that you get the perfect fit, you need to measure your wall and ceiling angle and choose the appropriate molding for your needs.

Step Two: Preparing your Saw

Once you have chosen the correct molding for your project, you need to prepare your saw. The compound miter saw is critical to the process, as it enables you to cut the molding at different angles. Before starting, set the saw blade to 45 degrees. Place a piece of scrap wood on the saw table, cut a test piece at 45 degrees, and check that the resulting cut is accurate. This test run will ensure that when you start cutting your molding, you won’t waste material or ruin the entire piece.

Step Three: Placing the Crown Molding

With your saw ready, the next step is to place the molding correctly on the saw table. To make the cuts successfully, position the crown molding with the back of the molding touching the fence and the bottom edge of the molding flush against the saw table. The upside-down orientation of the crown molding on the saw table is essential because it enables you to make cuts at the same angle as you will install the molding against the wall and ceiling.

Step Four: Making the Cuts

Once the molding is in position, it is time to make the cuts. Use the saw blade angle you set earlier and cut the molding. You will likely need to make several cuts for one piece of molding, using various angles. Every time you make a new cut, you will need to adjust the saw’s angle to match the angle of your wall and ceiling. Cuts should be made slowly and steadily to ensure you achieve an accurate cut.

Step Five: Installing the Crown Molding

When all your cuts are complete, you can now install the crown molding. Apply adhesive or nails to the moldings and attach them to the wall and ceiling. Use a nail gun to attach the crown molding flush against the wall and ceiling. You may need to secure the crown molding while the adhesive dries with temporary supports like clamps.


By following these steps, you will be able to cut and install crown molding like a professional. While it may seem intimidating at first, cutting crown molding with a compound miter saw is not as complicated as it may seem. Start slowly, practice your cuts, and don’t rush the process, and you will achieve your desired results.

So get ready to upgrade your home’s décor with beautiful crown molding.
