How to install chair rail: Beginner to expert in minutes

Installing chair rail can add a touch of elegance to almost any room. Originally devised to protect walls from the backs of chairs, chair rail is now primarily used as a classy finishing touch. Typically installed with a hammer and nails or a nail gun, it’s also possible to glue it on.

If you’re wondering how high a chair rail should be, the general rule is about three feet from the floor to the top of the chair rail. Alternatively, if you are using it for protection, place it according to the height of your chairs.

To determine how much chair rail you need, measure the walls around the room at the height you will install the chair rail. Here are the tools and supplies you’ll want to have on hand:

• chair rail moulding
• tape measure, pencil, and chalk liner
• level or laser level
• mitre saw
• hammer and nails or nail gun and compressor
• construction adhesive
  

Here are the details on how to install chair rail:

1. Use a level and a straight edge or a laser level to draw a horizontal line around the room at the correct height. If using a laser, snap chalk lines corresponding to the laser lines.
2. Use the mitre saw to cut a 45° angle on the first piece of chair rail and start it at a corner. Use a square cut as the chair rail ends into a door or window moulding.
3. If you have a run longer than a full piece of trim, cut a 45 on the end. Then cut an opposite 45° angle on the next piece to continue the run. This will give a better appearance than simply butting the two pieces together.
4. Install each piece as you cut it. Apply construction adhesive to the back of the chair rail and place it on the wall using your guidelines. If you wish to use nails, pre-mark the studs and nail through the chair rail into a stud.
5. If you decide on the glue-only method, you’ll need to prop the moulding up or tape it in place until the glue dries. You could also use a nail or two to hold it but using good-quality glue will vastly reduce the number of nails you’ll need.

Once you’re done, let the glue dry completely, caulk the moulding and paint it.

If there is wainscoting at the bottom of the wall, or if you are installing it at the same time as the chair rail, follow the same instructions as above. Choose a chair rail with a groove on the bottom to cover the top of the wainscoting. You’ll find many styles of chair rail designed for this purpose.
