Installing the New Pane

Then, remove the molding around the glass to expose the rabbet (the recessed area in which the glass sits). It is possible to remove any nails or staples that hold the molding in position. Once you have removed molding, carefully remove the old glass pane from the rabbet.
You are now ready to install your new pane. It is important to clean the surface of the rabbet by using a utility blade and sandpaper. This will get rid of any remaining putty. Clean surfaces will allow the putty to stick to the wood and will provide a weatherproof seal.
After cleaning the surface, knead some glazing putty in your hands until it is soft and malleable. Place the putty in the rabbet, making sure it is completely filled. The neatness of the putty doesn't matter as it will be covered by the trim later on.
When you are installing the new pane, be sure it is placed in the frame and that it is level. Insert glazier's tips into the frame, one on each side and press them down until they are flush with the glass. You should evenly space the points four to six inches apart for panes with a dimensions of 12 inches or greater.
After the glazier points are in place, you can trim them so that they are centered on the frame and glass. Paint the glazed area using an exterior oil-based primer. This will prevent the putty from drying out too quickly, thereby reducing its lifespan. Let the putty dry for 7-10 days before applying an exterior coat of paint.
