How do you install Crown moulding?


1. Select The Right Crown moulding for your space.

How Do You Install Crown Moulding

There are several different types of Crown moulding available in the market, so you may want to look around and determine which one you would like to use.

Pro Tip: Bring the Crown moulding to the installation environment and allow it to sit for a few days before installation. This will allow it to get accustomed to the temperature and humidity of the room.


2. Take the Right Measurements

Take The Right Measurements Install Crown Moulding

One of the most important steps in any installation is building a sketch of the area, understanding the lengths of every element involved, and calculating how much material would be required.

Pro Tip: If possible, it is best to opt for pieces that completely cover each wall. This would allow for a much smoother installation and a neater look overall.


3. Build a Guide

Build A Guide Install Crown Moulding

Crown molding tends to come in angles — 38º, 52º, 45º, etc. — and hence sits on the walls at an angle. This is why it’s best to create a guide for the miter saw to follow.

You will need to use a piece of plywood as a guide fence for this. Place it on a saw table of the same length with hot glue on both ends – on one end, place the miter saw and the other end would hold the Crown moulding. 

Pro Tip: When placing the Crown moulding on the saw table, ensure the decorative side is facing you and at the same angle at which it would be installed.


4. Make the Necessary Cuts

Make The Necessary Cuts Install Crown Moulding

When installing Crown moulding, you must make the right cuts in the right places in the right process. There are three main cuts here – scarf cuts, inner corner joints, and outer corner joints.

A. Scarf Cuts

These are simple enough and are used for those walls that are longer than the Crown moulding you have.

Determine the point at which you’ll be joining these two lengths and then place the first upside down into the miter saw. Adjust the blade at the right angle and then cut through the Crown moulding.

You can place the second length into the saw and use the blade to cut in the same position.

B. Cuts along the outside of Corner Joints

This is when two walls form a joint around the outside corner, making a 270º angle in the interior.

You need to take the first length from above, set it against the fence guide, and cut it around 45º. The second length from above should be cut in the same position holding the moulding you’ll be using on the other side.

C. Cuts along the inside of Corner Joints

On the other hand, this refers to the joint from the inside. So it is a little more complicated but a straightforward process nonetheless.

Here, the first length will be cut straight and sit along the wall. The second length will be at a 45º angle, but it will be cut so that it fits above the first length.

Pro Tip: Pay special attention to your Crown moulding angle here. The complexity of angular collaboration here is paramount in determining the right placement for each piece.


5. Final Installation

Final Installation Install Crown Moulding

With all the work we have set above, the final installation will be a fairly simple process where you just need to follow through on the steps mentioned below.

      • Take the first length of moulding and nail it in place. It is best to use finish nails here.
      • If there is a scarf cut, you should apply some glue to the scarf joint on the first moulding and fit it well while adding the second length with finish nails.
      • Select a direction — clockwise or counter — and follow it through to nail the rest of the molding.
      • If a corner joint is too long, take a rasp and even it out to the desired length.
      • Give the entire set a neater look by using 100-grit sandpaper that can smoothen the Crown.
      • You can further paint the Crown moulding into your desired color if required.
      • When the paint sets, your Crown moulding is fully ready!

Pro Tip: If you use the right amount of nails as required, you will have fewer nail holes to look after later. So, pay special attention and ensure each move serves a purpose.
