Moulding  
Begin by removing the existing chair rail if installed.  
1. Using a utility knife, cut along the joints where the chair rail 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 wall 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 chair rail 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 chair rail you will need to 
purchase.  
4. Add 10% to that total for waste and miter joints (Tip: deduct the width of any doorways, windows or 
cased openings to get an accurate total).  
Choose a wall to begin installing your new chair rail. Measure the desired height of your chair rail from 
the floor to a point on the wall. A common chair rail height is 36 inches. Depending upon your specific 
style and needs, the height could vary. Mark you desired height across the wall in several places. Using a 
level as a guide, mark a straight line across the wall for reference when you begin installing your chair 
rail.  
5. Cut your first piece to length. Be sure to cut it a little long to allow for your miter joint.  
a. If you are installing a piece of moulding between two doors, windows or cased openings, each end will 
need to be cut straight to fit tight against the casing.  
b. If you are beginning with an inside corner, cut the moulding at a 45 degree angle across the face of 
the moulding. This cut will make the back side of the moulding that goes along the wall longer than the 
face of the moulding.
