The first step to glazing a window is to remove the old glazing and putty. To do this, use a putty knife to gently pry up the old glazing compound and putty. Be sure to wear gloves and safety goggles to protect your hands and eyes from any flying debris.

Step 2: Clean the Window Frame

Once you’ve removed the old glazing and putty, clean the window frame thoroughly. Use a scraper or wire brush to remove any stubborn debris or old paint. If necessary, sand the frame to create a smooth surface for the new glazing.

Step 3: Choose Your Glazing Compound

There are several types of glazing compound available, including oil-based, latex-based, and hybrid-based. Choose the type of glazing compound that best suits your needs and preferences.

Using a putty knife, apply the putty around the edge of the window frame. Be sure to press the putty firmly into place and create a smooth, even surface.

After applying the glazing compound, use a glazing tool or putty knife to smooth and shape the glaze. This will create a neat and tidy finish.

Step 8: Allow the Glaze to Dry

Let the glaze dry completely before painting or applying any finishing touches to the window.

Once the glaze is dry, use a fine-grit sandpaper to smooth any rough edges or surfaces.

If desired, paint the window frame to match the surrounding décor.
