Use masking tape to create an "X" over the broken glass to prevent shards from falling out as you work. Tools Needed: Replacement glass (measured 3mm smaller than the frame opening) Glazing point driver or small hammer Glazing compound (putty) Putty knife Heat gun or oscillating tool (optional, for stubborn old putty) Linseed oil or exterior primer 2. Remove the Old Glass and Putty Clear the Shards: Carefully pull out the broken glass. If the glass is stuck, use a putty knife to pry it away from the frame.

Position the Glass: Press the new pane firmly into the bed of putty to create a weather-tight seal. Secure with Points: Push metal glazing points into the wood frame every 4–6 inches. Use a putty knife or specialized driver to slide them flat against the glass so they hold it in place. 4. Apply the Glazing Compound Soften the Putty: Roll a handful of glazing compound between your palms until it’s a warm, pliable "rope." Press into Place: Press the rope into the corner of the frame against the glass. The Finishing Stroke: Use a putty knife at a 45-degree angle to smooth the compound into a clean, sloped bead. The goal is to match the angle of the surrounding window muntins. Clean Up: Use a soft cloth to remove any oily residue or "fuzz" from the glass surface. 5. Curing and Painting Glazing compound needs time to form a "skin" before it can be painted. Depending on the brand and humidity, this can take
