You will need the following materials to cut crown molding the flat way: a piece of crown molding, a miter box, a saw, and sandpaper. You will also need a helper to hold the molding in place while you’re cutting it.

Crown molding

Crown molding is decorative molding that is used to cover the junction of a wall and ceiling. It is usually made of wood, although there are also plastic and polyurethane crown moldings available. Crown molding can be found in a variety of different styles, from simple to ornate. The most common type of crown molding is the picture frame style.

Cutting crown molding flat is a simple way to install it that does not require any special skills or tools. You will need a miter saw, a power drill, and some basic carpentry skills. The following steps will show you how to cut crown molding the flat way.

1. Measure the width of the wall where you will be installing the crown molding. Measure from corner to corner and transfer these measurements onto a piece of paper.

2. Cut two pieces of crown molding to the length of your measurement using a miter saw set at 45 degrees. These will be your outside corner pieces.

3. Cut two more pieces of crown molding at 45 degrees, but make these cuts slightly longer than the length of your measurement. These will be your inside corner pieces.

4. Drill pilot holes into all four pieces of crown molding using a power drill and appropriate size drill bit for your screw material (wood screws or drywall screws). The pilot holes should be evenly spaced along each piece, about 6 inches apart.


Miter saw

One of the most important tools for cutting crown molding is the miter saw. There are two types of miter saws: the standard and the compound. The standard miter saw cuts at a 90-degree angle, while the compound miter saw can be adjusted to cut at angles other than 90 degrees.

Most crown molding projects will require cuts at angles other than 90 degrees, so it is generally recommended that you use a compound miter saw. If you do not have a compound miter saw, you can still use a standard miter saw, but you will need to make additional cuts to your molding in order to create the angled cuts that are necessary for crown molding.

In addition to the miter saw, you will also need a measuring tape, a level, and a pencil. You will also need something to catch thedust generated by the cutting process; either a shop vac ora dust mask should suffice.

Coping saw

A coping saw is a type of hand saw that is specifically designed for cutting intricate shapes in wood. It has a very thin, narrow blade that is held in place by a metal frame. The blade can be removed from the frame, which makes it easy to change out blades as needed. Coping saws are typically used for cutting moldings and other trim work.

Nail gun

A nail gun is a tool that drives nails into wood or another material. It is operated by electricity, battery, or compressed air. Nail guns have replaced hammers for many do-it-yourself and construction projects because they are faster and easier to use.


The first step is to understand which way the crown molding must lay in order to achieve the flat cut. Most crown molding has a top and bottom edge. The bottom edge is the one that will lay flat against the wall. The top edge is the one that will be visible once the molding is installed. In order to cut the molding so that the top edge is flat, the molding must be installed upside down.

Measure the wall

Crown molding is a type of decorative trim used to cover the junction of a wall and ceiling. It can add a touch of elegance to any room, but many people shy away from it because they think it’s too difficult to install. Crown molding is actually quite easy to install, and the “flat way” is the simplest method. With a few basic tools and some careful measuring, you can install crown molding like a pro.

Measure the wall where you will be installing the crown molding. Make a mark at the top of the wall at each end. Measure the distance between these marks and transfer this measurement to your piece of crown molding. Cut the crown molding at a 45-degree angle using a miter saw.

Position the first piece of crown molding so that the long edge is flush with the mark on the wall and the short edge is pointing up. Use a level to make sure that the piece is level before you nail it into place. Nail the crown molding into place using finish nails and a hammer or pneumatic nail gun.

Cut another piece of crown molding at a 45-degree angle, but this time make sure that the short edge is pointing down. Position this piece so that it butts up against the first piece of crown molding and nail it into place. Repeat this process until you reach the end of your wall.

Cut the molding

There are two schools of thought when it comes to cutting crown molding: the outside method and the inside method. You can use either method, depending on your preference, but we recommend the inside method because it’s easier and gives you a cleaner cut.

Here’s how to do it:

1. Cut the molding at a 45-degree angle using a miter saw.

2. Place the molding upside down on the saw table with the long point of the miter cut pointing up.

3. Set the blade to make a bevel cut at 33 degrees.

4. Turn on the saw and carefully make the cut.

Attach the molding

Crown molding is used to create a decorative border along the top of a room where the walls and ceiling meet. Crown molding is sold in long lengths and is typically made from wood, although polyurethane crown molding is also available. The most common method for attaching crown molding involves mitering the corners of the molding so that the pieces fit together snugly. However, you can also cut the crown molding so that it lies flat against the wall, which is known as the flat method. The flat method is easier because you do not have to worry about making precise miter cuts.

1. Measure the length of the wall where you will be installing the crown molding. Cut two pieces of quarter-round molding to this length using a miter saw.

2. Set one piece of quarter-round molding flush against the wall with the top edge aligned with the ceiling line. Attach it to the wall using finishing nails and a hammer or an electric screwdriver fitted with 1-inch screws.

3. Fit the second piece of quarter-round molding against the first piece, aligning the top edges. Use finishing nails or screws to attach it to the first piece and to the wall.

4. Fill any holes left by nails or screws with wood putty then sand smooth once dry


Crown molding is one of the most popular ways to finish off a room. It can add beauty and value to your home. Crown molding is usually installed by professional carpenters, but you can do it yourself with a few tools and a little patience. The most important thing to remember when installing crown molding is to cut the molding the flat way. This will make the installation process much easier and will give you a professional looking finish.

Nail the molding

To install crown molding the flat way, you’ll first need to nail the molding in place. Start by holding the molding up to the ceiling and marking where you’ll need to make your cuts. Then, use a miter saw to cut the molding at a 45-degree angle. Once you’ve cut all the pieces you need, fit them into place and nail them in with a finishing nailer. Be sure to putty over any nails that are visible.

Caulk the molding

Use painters’ caulk or a similar product to seal the gaps between the molding and the wall. Smooth the caulk with your finger, then wipe away the excess with a damp cloth.

Paint the molding

Once you have your molding cut and installed, you’ll want to paint it. I suggest using a semi-gloss paint for trim because it’s easy to clean and it doesn’t show imperfections as much as a high gloss paint would.

If you’re painting the molding in place, you can use painter’s tape to mask off the wall and ceiling. I like to use Frog Tape because it doesn’t bleed like other tapes. If you have baseboard molding, you can tape that off too so you don’t get paint on it.

Once the tape is in place, you can start painting. I like to use a 2-inch angled sash brush for this because it helps get into all the nooks and crannies. Work in small sections so the paint doesn’t dry before you have a chance to smooth it out. When you’re finished painting, remove the tape while the paint is still wet so you don’t pull off any paint with the tape.
