How to Repair Windshield Chip at Home (8 Simple Tips)

A windshield chip can be an annoying problem for car owners, but it doesn’t have to be a costly repair. With the right tools and techniques, you can fix a chip in your windshield at home. In this blog post, we’ll discuss eight simple tips for repairing a windshield chip at home.

Tip 1: Assess the Damage

When assessing the damage of a windshield chip, it’s important to look at its size, location, and depth. As mentioned before, chips that are larger than a quarter or located in the driver’s line of sight will likely require windshield replacement.

You should also check the depth of the chip, as deeper chips may require more extensive repair methods. If the chip has penetrated the top layer of glass and the inner layer of plastic, it may be more difficult to repair. In this case, it’s best to consult a professional for guidance on whether the chip can be repaired at home or if the windshield needs to be replaced.

Assessing the damage thoroughly will help you determine whether you can repair the chip yourself or if you need to seek professional help. If the chip is too large or too deep for DIY repair, it’s best to have a professional replace the windshield to ensure the safety of you and your passengers.

Tip 2: Gather the Right Tools

Before attempting to repair a windshield chip, it’s important to gather the right tools. Here are some of the tools you’ll need to repair a windshield chip at home:

  • Windshield repair kit: You can purchase a windshield repair kit at an auto parts store or online. These kits typically include a resin injector, a resin, a curing film, and a razor blade.
  • Safety gloves: Safety gloves will protect your hands from any glass shards that may be present.
  • Cleaning supplies: You’ll need a glass cleaner and a lint-free cloth to clean the area around the chip before starting the repair process.
  • Razor blade or drill: If the chip has a bullseye or star-shaped crack, you may need to use a razor blade or drill to create a small hole in the center of the chip. This will allow the resin to flow into the crack and fill it properly.
  • Heat source: A heat source, such as a hairdryer or heat gun, may be needed to cure the resin and complete the repair process.

Tip 3: Clean the Area 

Before beginning the repair process, clean the affected area with mild soap and water. Rinse the area thoroughly and dry it with a clean, lint-free cloth. Avoid using any harsh chemicals or abrasive materials as they can damage the windshield.

Tip 4: Use the Applicator

Once the area is clean, apply the resin or adhesive using the applicator. Follow the instructions on the kit carefully, as the process may vary depending on the kit you’ve purchased. Typically, you’ll need to apply the resin or adhesive to the center of the chip, covering it completely.

Tip 5: Apply Curing Film

After injecting the resin into the chip, you will need to apply a curing film over the top of it. The curing film is a clear, adhesive film that helps to seal the resin in place and protect it from dirt and debris. Here’s how to apply curing film to a windshield chip:

  • Use a razor blade or sharp object to remove any excess resin from the surface of the windshield. This will make it easier to apply the curing film.
  • Cut a piece of curing film to size. Make sure that it is slightly larger than the chip itself.
  • Peel the backing off of the curing film and carefully apply it over the top of the chip. Be sure to press down firmly to ensure that the film adheres to the windshield.
  • Use a straight edge or credit card to remove any air bubbles from under the curing film. This will help the film to seal properly over the resin.
  • Allow the curing film to sit on the windshield for the recommended amount of time. Check the instructions on your windshield repair kit for specific details.
  • After the curing time is up, carefully remove the curing film from the windshield. Use a razor blade to trim any excess film from the edges of the chip.

Tip 6: Remove the Curing Film

After the resin or adhesive has been cured, carefully remove the curing film from the windshield. Use a razor blade to remove any excess resin or adhesive from the windshield.

Tip 7: Use a Drill for Deeper Chips

If the chip is deeper, you may need to use a drill to create a small hole at the center of the chip. This will help the resin or adhesive penetrate deeper into the chip and fill it completely. Use a small drill bit and be careful not to drill too deeply or too quickly.

Tip 8: Allow Time to Cure

After completing the repair process, it’s important to allow the resin or adhesive to cure completely. This can take up to 24 hours, depending on the kit you’ve purchased. Avoid driving the car or exposing the windshield to extreme temperatures or harsh weather until the repair has fully cured.


Repairing a windshield chip at home is a relatively easy and cost-effective process that can save you money compared to having it professionally repaired or replaced. By following these 8 simple tips, you can successfully repair a windshield chip yourself with a windshield repair kit and some basic tools. Remember to always prioritize safety and take the necessary precautions when working with glass. If the chip is too large or deep, it’s best to have it professionally repaired or replaced to ensure the safety of you and your passengers on the road. With the right tools and techniques, you can effectively repair a windshield chip and maintain the safety and integrity of your windshield.
