How to Apply Glazing to My Exterior Windows

It is important to replace the glazing of your exterior windows once every 15 to 20 years. Properly maintained glaze on exterior windows lowers the cost of your heating and cooling bills. The process of applying glaze to your external windows is less difficult if you have the proper tools. You can find the necessities you need at any local hardware store.

Difficulty: Moderate

Instructions

Things You'll Need:

• Glazing
• Putty knife
• Ladder
• Heat gun
• Primer
• 2 paint brushes
• Wil-Bond

1. Remove the old glazing. To remove the old glazing from your exterior windows, you will need to use a heat gun and a glazing knife. Apply the heat gun to the existing glazing to loosen it. Slowly peel the glazing around the window, being careful not to chip the glass or cut the wood.

2. Replace the points. As you are removing the glazing from your exterior windows, you will find metal points around the window. They are pushed into the wood and hold the window in place. If they are damaged during the glazing removal, replace them. You can purchase them at your local hardware store.

3. Prime the window. Lightly sand the window frame where the old glazing was. Clean the window with Wil-Bond, which is a liquid deglosser. Use a quick drying oil or water-based primer sealer to prime the window where the old glazing was.

4. Apply the glaze to the window. Apply a 1/4-inch bead of glaze around the window. Take your putty knife at a 45 degree angle and smooth the glaze with the corner of the putty knife. Allow the glaze to dry completely before painting or staining.
