While all types of glass eventually crack, windshields tend to crack more frequently than other windows because of the stress it undergoes. That stress can lead to something much worse than a small crack — it can cause the crack to spread.
How, then, can you avoid these outcomes and get your cracked windshield repaired? Here’s how to stop a windshield crack from spreading.
Avoid Temperature Extremes
One important step to take to stop a windshield crack from spreading is to avoid temperature extremes. This means that anytime the temperature drops below freezing, it is important to keep your vehicle out of direct sunlight and out of the cold, if possible.
If the temperature inside your vehicle reaches a high level, either from direct sun exposure or heat from an engine, it is important to take care when opening and closing the vehicle doors to let the hot air out. Taking the time to avoid temperature extremes and shocks to the windshield can go a long way in ensuring that a crack remains, and doesn’t spread.
Use Clear Nail Polish or Superglue
Using clear nail polish or superglue is an effective way to stop a windshield crack from spreading. Clean the windshield crack with isopropyl alcohol to ensure that any debris is removed. Then, using a drill bit about the same size as the crack, carefully drill a hole at the end of the crack.
Apply a generous amount of clear nail polish or superglue into and around the crack and spread it evenly with a scraper or a popsicle stick. Allow it to dry for about 24 hours before driving your vehicle. Make sure to check every few days for ongoing spreading as additional nail polish or superglue might be needed to seal and prevent further issues.
Use a Windshield Repair Kit
If you see a small crack in your windshield and do not have the time to visit a glass company, it is possible to repair it with a windshield repair kit in the meantime. The kit typically contains a resin-filled injector and several tools that are necessary for repairing the windshield. Begin by cleaning the glass, then follow the instructions provided with the kit to inject the resin into the crack.
Be sure to keep the repair area dry during the process and allow the resin to fully cure before using the vehicle. To prevent the crack from spreading further, use a razor blade or a small drill to remove any loose glass around the crack.
Use a diamond file or a drill bit to roughen the surfaces around the crack. Apply a clear coating to the outside surfaces of the windshield to protect the glass and help keep the crack from spreading.
