As a temporary measure you can repair chipped windows by following the simple step by step instructions below. However; we can’t over-emphasize enough that this is a temporary measure and you should replace the broken glass as soon as you can. This is especially true for double pane windows. If the chip has breached the thickness of the glass, then you have broken the seal which will allow moisture and air into the gap between the two panes of glass. This will compromise the integrity of the window and ultimately lower its thermal efficiency.
Easy Steps to Repair Chipped Windows
Step 1: Completing the repair, using an automotive windshield repair kit, will be much easier if you can lay the window flat. Most double hung windows can easily be removed from the window casing by opening the window slightly and tilting the sash inward.
Step 2: Lay the window sash on a flat surface. Use a pin or sharp awl to remove any loose particles of glass. Safety glasses should be worn during this step.
Step 3: Clean the chipped area using an alcohol pad to remove any dirt or loose debris.
Step 4: Attach the donut ring over the chipped area. Depending on the brand of the kit you are using this may be accomplished by peeling off the protective backing to expose the adhesive strip, or the kit may be equipped with suction cups.
Step 5: Attach the resin chamber to the donut ring by screwing the chamber into the ring or in some cases it is affixed using an adhesive backing.
Step 6: Squeeze a few drops of resin into the resin chamber. If your kit includes a syringe, place the tip of the syringe into the adapter and pull back on the plunger. If your kit features a threaded insert, screw the pressure driver clockwise and tighten until the pressure driver is almost bottomed out.
Step 7: Allow the resin to flow into the crack for about 5 minutes then retighten the insert by turning it an additional ¼ turn.
Step 8: Unscrew the pressure driver or remove the syringe. Gently remove the suction cups or adhesive backed ring.
Step 9: If any visible damage remains, add a drop of resin. Wipe off any excess resin that may have escaped during the application process then apply a curing strip over the repaired area. DO NOT APPLY PRESSURE.
Step 10: Allow the repair to cure for an additional 10 minutes. Curing is accelerated in direct sunlight or you can use an ultraviolet light. Once the resin is fully cured, remove the curing strip and scrape away any excess resin by using a razor blade scrapper tool.
We should reiterate that this is a temporary measure to repair chipped windows. For a long-term solution you must replace the broken glass.
