How to Glaze a Window

Remove Old Glass and Putty

• 1

  Put on safety glasses and work gloves.

• 2

  Cover old glass with rag, or put an "X" of duct tape on either side to prevent shattering.

• 3

  Tap the center of glass gently with a hammer to break window.

• 4

  Remove the old glass by hand.

• 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.

• 6

  Remove any glazing points (these are metal fasteners that keep the glass in place) by hand or with needle-nosed pliers.

• 7

  Sand window frame with sandpaper.

• 8

  Paint exposed wood with an oil-based primer or linseed oil. This prevents the wood from drying out.

Glaze Window

• 9

  Remove work gloves and knead a hand full of putty until warm. Form a putty rope approximately 1/16-inch in diameter.

• 10

  Place the putty rope along the windowpane's inside edge. Use a putty knife to press putty firmly into place.

• 11

  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.

• 12

  At the center 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.

• 13

  Apply downward pressure with the putty knife, until the glazing point is firmly in the wood.

• 14

  Repeat this process on the other side of the window. Then add glazing points to the center of the top and bottom on both sides.

• 15

  Place another rope of putty along the window frame.

• 16

  Use the putty knife at a 45-degree angle to remove the excess putty from both sides of the windowpane.

• 17

  After allowing 7-10 days for the putty to dry, paint the putty to match the rest of the window.
