How to Glaze Wooden Windows

Inspect the perimeter of the glass pane for glazier's points. These are small flat bits of diamond-shaped metal that are inserted into the wooden sash and hold the glass in place until the glazing is completed and cured. There should be two on each side of the window pane.

Install any missing glazier's points by placing them flat on the pane with one point touching the wood. Place the tip of a flat bladed screwdriver behind the raised ridge in the middle of the point and push it into the wood until the ridge presses against the wood.

Roll a golf ball-size glob of window glazing between the palms of your hands, elongating it into a rope-like shape.

Place this glazing rope along one side of the window so that it is pressed firmly against the wood and the glass.

Press the glazing into place by putting one corner of a putty knife roughly 1/4 inch from the edge of the window pane. Let the blade rest on the wood. Pull the putty knife along the length of the window pane.

Remove any squeeze-out from the top of the wood and the glass pane. Repeat for all sides of the window pane.

Allow the glazing to cure for 48 hours before operating the window.
