How Do You Cut Crown Molding

Flat Is Where It’s At

How To Cut Crown Molding For Beginners

Refer to this chart for mitering non-square corners, such as around a bay window or range hood.

Cutting crown molding while it lies flat on the mitersaw table allows easy cutting of both long and short pieces an unwieldy piece can be firmly clamped to the mitersaw because it doesn’t rest at an angle. Cutting the trim flat calls for some rather complex math to determine the proper settings for the bevel and miter cuts. But don’t worrymitersaw manufacturers have done the math for you and placed markings on the tools for the proper angles: 33.9° on the bevel scale and 31.6° on the miter scale . You’ll see these numbers or some other obvious markings that indicate the “crown” settings. You may have wondered what those markings or stops were for. Now you know.

The Anatomy Of Crown Molding

Crown molding comes in many sizes and styles. Youll notice, though, that most types have these featuresa flat surface at the top, a flat surface at the bottom back, and the corner section is hollow when installed.

You may occasionally run into solid crown molding options where the corner section is solid, but its not as common.

Note that the bottom, in many cases, has a flat surface area thats larger than the top. Youre typically nailing through the bottom, so the larger surface area allows for more room to nail and a more secure hold.

Also, the flat top and flat back sections are 90 degrees to each other so these should fit square into a cornerlike the corner where a wall meets a ceiling.

Of course, not every application using crown molding is for walls and ceilings. In many cases, I use crown molding for furniture pieces to give it some extra detail. And in this case, I used it to trim out a window.

You can cut crown molding many ways, but a miter saw is a quick and easy way, so thats what Im sharing here.

Crown molding can be installed in different orientations. Ill discuss in detail below, but first, lets compare inside vs. outside corners.

Here Is An Easier More Precise Method You Can Use To Cut Crown Molding While It’s Flat On A Miter Saw

Cutting molding on a miter saw can be tricky business. Most techniques for cutting crown molding involve awkwardly holding the crown against the fence of the saw while making the cut. With this method the crown can be laid flat on the saw, which makes the whole process a little easier and a lot more precise.

Note: This method is for cutting crown molding to fit a 90-degree corner.

    How To Cut Crown Molding Corners

    Crown moulding is often cut with a compound miter saw. A miter saw allows trim to be cut at any angle. The fence and base of the saw mimics where walls and ceilings meet at 90 degrees.

    The two main methods for cutting crown moulding are the nested method and the flat method. Both techniques require the use of the powered miter saw. The nested method uses the saw fence and eliminates the need for a bevel cut. The flat method is a compound cut where the bevel and miter angles are cut at the same time.

    Painting And Crown Molding

    If you are painting the room where you are planning to install crown mold, paint the room first. If the ceiling and the walls will be two different colors, you don’t have to be too precise when cutting in the edge of the ceiling with a paint brush. The crown mold will cover it up.

    You can also paint the crown mold before you install it, then nail it in place, set the nails, putty the nail-holes, and perform any necessary touch-up afterwards. If you have any questions about how to install crown molding, please Contact Us.

    Just a quick thought about miter saws. I installed my 2 1/2″ crown molding using the 10″ model shown in the pictures, but when I buy my next miter saw, I will get a larger one , because I want to be able to cut 1x6s and 4x4s, etc.. It all depends on what you plan to use it for. My advice? Plan ahead.

    S For Mitering Crown Molding

    For a smooth look all the way around your trim that doesn’t require corner pieces or connectors, the job gets a bit more complex. Mitering and coping do give a clean look to your trim, but it is a job for experienced DIYers. These processes are usually reserved for professionals, but if you have experience with mitering and coping, and you can afford to fix any mistakes, you could always try to cut your crown molding this way.

    You can use the mitering and coping steps below for our Focal Point crown molding if you prefer a smooth finish, but this is also the method you need for other styles of trim. When you’re working with foam, along with other options such as woods or plaster you may prefer not taking any shortcuts when you’re making your cuts. You need to use high-quality equipment that produces reliable, consistent and clean cuts, all while maintaining strict measurements the whole way through. You may not have all the tools you need already, so be sure you have:

    • An adjustable protractor
    • A coping saw
    • A nail gun

    Work carefully with these tools, especially if you aren’t familiar with them. Read their manuals and research how-to guides or watch helpful videos on YouTube to avoid injury or damaging your tools or crown molding. From there, the steps you should take include the following.

    Crown molding involves two wood panels that meet at angled edges in the corners between a rooms wall and ceiling. It provides an elegant transition between the wall and ceiling, and it never really goes out of style.

    To make miter cuts in crown molding, turn a panel upside down on the miter saw table. This allows the angled back edges to rest against the fence and the table during cutting.

    Holding the molding in the right position while you make a cut is the difficult part.

    The solution is to hot-glue a piece of 1-by-2 wood to the saw table so it acts as a cleat to hold the molding in the proper position.

    How To Measure Length

  • Measure for length first and create a cut list that includes length, type of corner, and type of cut. Also consider drawing a chart of the room with all the corners and adding the measurements to itthis can be very useful.
  • Take the length measurement from where the crown hits the wall, not the ceiling. This is the bottom run of the crown.
  • The first measurement and cut should be a flush, square cut along the longest wall.
  • How To Cut Crown Molding Corners With A Handsaw

    Crown molding is often 4 inches wide, and it sits at a 45-degree angle with respect to both the wall and the ceiling. Cutting the ends so that pieces fit together cleanly can be difficult, especially if the walls aren’t exactly square. Only the most precise craftspeople can do it freehand when using a handsaw everyone else needs the help of a miter box. If you don’t have a miter box, it’s easy to build one by screwing together three straight 1-by-6-inch boards to make a box with an open top and sides.

  • 1.

    Prepare the miter box — if you’re making one yourself — by measuring a 45-degree angle on the top edges of the two boards that form the sides of the box, using a combination square. Mark lines on both boards with a pencil, and cut through them with a handsaw. The cut line should extend all the way to the bottom of the box. Cut an identical 45-degree angle that splays in the opposite direction, using the same technique.

  • 2.

    Insert a piece of crown molding into the box with its bottom edge facing up. Hold it so that it’s angled against the bottom and side of the box in exactly the same way that it fits against the wall and the ceiling, and cut the end at a 45-degree angle. The top edge of the piece you’re going to use, which is facing down in the box, should be the longer edge.

  • 4.

    Miter outside corners in the same way. The difference is that the bottom edge of the piece you’re cutting, which is facing up in the box, is longer than the top.

    There are two ways to cut crown molding for an inside corner. The first method is to cut 2 pieces at an angle and fit them together. This is usually done with a miter saw. This method works best for perfect 90-degree corners where you dont need to worry about compensating for strange angles. The other option is to cope your corners. This is done by installing one piece of crown molding on top of an uncut piece that sits flush with the wall. To do this, youll need to miter one length, then use a coping saw and a file to wear away the wood behind the cut. Coping your corners will result in a tighter fit, but its harder to do and requires more work.
