Measure the opening carefully and subtract about 1/8 inch from both the height and width. This small gap allows for the natural expansion and contraction of the window frame. Have a new pane cut at a local hardware store, or cut it yourself using a glass cutter and a straightedge. 4. Setting the Glass
With the glass removed, you must prep the wood for the new installation. how to repair broken window pane

After the putty has cured (usually a few days), you can paint it to match the frame, ensuring the paint slightly overlaps onto the glass to create a weather-tight seal. Measure the opening carefully and subtract about 1/8
Roll a small amount of glazing compound into a thin "rope" and press it into the frame's recess. Press the new pane firmly into this bed of putty. Next, drive new glazing points into the frame every six inches to secure the glass. 5. The Final Seal Use a putty knife held at a 45-degree
If the glass is still largely intact, apply crisscrossing masking tape over the cracks. This helps hold the shards together and prevents them from falling out unexpectedly.
Allow the glazing putty to dry completely. This usually takes several days depending on humidity and temperature. Do not skip this waiting period, as painting too soon will ruin the putty.
