Remove
Old Glass and Putty
Step 1
Put on safety glasses and work gloves.
Step 2
Cover old glass with rag, or put an "X" of duct tape on either
side to prevent shattering.
Step 3
Tap the centre of glass gently with a hammer to break window.
Step 4
Remove the old glass by hand.
Step 5
Remove the old putty with a putty knife or small chisel. You can
also heat the putty with a heat gun to soften it.
Step 6
Remove any glazing points (these are metal fasteners that keep the glass
in place) by hand or with needle-nosed pliers.
Step 7
Sand window frame with sandpaper.
Step 8
Paint exposed wood with an oil-based primer or linseed oil. This
prevents the wood from drying out.
Glaze Window
Step 1
Remove work gloves and knead a hand full of putty until warm. Form a
putty rope approximately 1/16-inch in diameter.
Step 2
Place the putty rope along the windowpane's inside edge. Use a putty
knife to press putty firmly into place.
Step 3
Put on work gloves and place the new pane of glass in frame, pressing
gently to make sure the glass and putty form a complete seal.
Step 4
At the centre of each side of the pane, place a glazier's point flat on
the glass and place the edge of the putty knife against the point's raised
edge.
Step 5
Apply downward pressure with the putty knife, until the glazing point is
firmly in the wood.
