with safety glasses and a good pair of work gloves.

Start by removing the broken
glass pane remnants still stuck in the window sash. You may need to use
one of your pliers to help pull out any smaller pieces.
Next, remove the old glazing compound
with your putty knife. Work your way around the entire window sash, in either a
clockwise or counterclockwise direction, and scrape the old glazing compound
out.
You may want to use a hair dryer to
heat the glazing compound up. The heat will soften the old glazing compound and
make it easier to remove. Apply heat to a localized section of the old glazing
compound to soften it up, and then scrape it out with your putty knife. Keep
stepping around the window sash in this process.

Also, in the process of removing
the old glazing, remove any glazing points that may still be attached to the
window sash. Use your Needle-nose pliers to remove the points.
After you have removed all of the
glazing compound and glazing points, sand the area down to the bare wood to
remove any old glazing compound or paint pieces. Then apply a sealer to the bare
wood to protect it.

Now install your new piece of window glass into the window sash. Note that the glass should be slightly smaller
than the window sash, e.g. 1/8th inch narrower in both length and
width.
With the glass in place, install
glazing points approximately every 4-6 inches, making sure you have a couple of
glazing points near each of the corners of the glass. Be careful not to break
the glass when doing this.
With the glazing points installed
apply the new glazing compound to the window sash. It is best to roll out a ¼”
string of glazing compound, and using your fingers and putty knife push it into
place around the window edges.

Once you have pressed in the new
glazing compound, use your finger or a moist rag to smooth out the glazing
compound and to clean the glass.
Let the glazing compound dry
overnight, and then apply paint to the window sash. When the paint has dried
reinstall it into the window frame.
