How to install crown moulding

Materials needed include:

 Utility knife

 Tape measure

 Miter saw or miter box

 Level

 Flat bar

 Hammer or nail gun

 Finish nails

 Nail set

 Wood glue

 Safety glasses

 Moulding

Begin by removing the existing crown moulding if installed.

1. Using a utility knife, cut along the joint where the top of the crown moulding and ceiling

intersect. Repeat this process where the bottom of the crown moulding and wall intersect. This

will loosen any paint or caulk and prevent damage to the sheetrock.

2. Starting in a corner, insert your flat bar between the wall and the moulding. Gently pry the

moulding away from the walls being careful not to damage the sheetrock (Tip: use a putty knife

in between the flat bar and the wall to protect the sheetrock). Continue along the length of the

moulding pulling it away from the wall until you can remove the entire piece. Continue around

the room until all crown moulding is removed.

3. Make a sketch of your room. Measure the length of each wall and record that measurement on

your sketch. Add those numbers together to determine the total lineal feet of crown moulding

you will need to purchase.

4. Add 10% to that total for waste and miter joints.

Choose a wall to begin installing your new crown moulding.

*Tip: Before beginning, cut templates for inside corners and outside corners. Each corner will

have a left hand and right hand side. This will save time and reduce errors in setting your miter

angles as you begin cutting each piece of moulding.

*Tip: Depending upon the overall size of the crown moulding being installed, it may be

necessary to install nailing blocks or strips around the room. If you’re using crown moulding

that is over 3 inches in width, you may want to consider using a nailing block. Once the blocks

are installed, there should be at least ¼ inch between the block and the back of the moulding.

When installing crown moulding, there are two methods that can be used to cut an inside corner. You can simply miter 45 degree angles to achieve the appropriate cut or you can choose to cope the inside corners. A coped cut requires cutting the back side of the moulding to match the profile of the front side. The coped cut will butt up to the profiled front of the moulding once installed. We’ll cover both methods. Always remember to place your crown moulding upside down on you miter saw.

Installing your crown moulding using a coped joint Coped joints are only used on inside corners. One side of the moulding is simply butted against the wall. The joining piece will be coped to fit the profile of the moulding. A coped cut requires cutting the back side of the moulding to match the profile of the front side. The coped cut will then butt up to the profiled front of the moulding once installed. Outside corners will be cut as detailed above. 1.
