How to Glaze Exterior Windows

Wooden windows need to be checked regularily for loose glass and missing areas of caulking or glazing. Most of these windows use glazing to seal the glass tightly against the frame and keep the weather out. Glazing a window is simple with the right tools and directions.

Removal Of Old Glazing

• Use a utility knife by taking the sharp point and placing it downwards against where the glass and glazing meet.


• Cut a line the length of the glass, being careful not to apply pressure to the glass itself.


• Take a flathead screwdriver or putty knife and scrape away the old glazing until you see where the push points are located.


• If the glass is broken, finish removing the old glazing and lift out the push points with a screwdriver, starting at the bottom and finishing with the top.


• Remove the glass, then use a wire brush and putty knife to finish cleaning up the window frame.


• Leave the glass and push points in place if you only need to re-glaze the window.


• Check to make sure the frame is completely free of any debris.

Apply Glazing To Window And Frame

• Choose a glazing compound color that will look good with your home.


• Open the can of putty and remove a small amount. Warm the putty in your hands for easier application.


• Roll it into a tube and lay it against the frame and glass. Use a putty knife to smooth it evenly and give the glazing a clean edge.


• Continue around the window frame until you have finished.


• Allow several weeks of drying time before adding finish paint or stain.
