5-in-1 painter’s tool
needle-nose pliers
sandpaper
paint brush
tongue depressor
putty knife
clean cloth
glass
glazing

1. Use a heat gun and painter's tool to remove old glazing. Heat the glaze in sections, holding the gun over each section for 5 to 10 seconds until glazing starts to soften. Then pry away glaze with painter's tool (figure A). Remove old glazing by pealing it away.

2. Be careful not to cut any wood away as you remove the glazing

3. Pull out old nails or brads holding existing glass in place using needle-nose pliers. Remove old glass or plastic panel.

4. Using the heat gun, remove any leftover glazing and clean area. Sand area and brush away any dust or debris with a dry paintbrush.

5. Paint opening with primer. It is important to prime before glazing so the wood does not soak up the oils from the compound.

7. Place the glass in the frame. The glass pane should be 1/8-inch smaller in dimensions than the window opening.

8. Secure the windowpane with glazing points (figure C). Press points into the window frame around the perimeter of the opening. Use a putty knife to press points into place.

9. Load up the putty knife with glazing and smoothly apply around perimeter of window opening (figure D). Miter the corners for a smooth look.

10. Wait until the glazing is firm before priming and painting window frame. It should take glazing about a week to set up.
