How to fix chips in your windscreen

Fixing chips or small cracks in a windscreen is a task that many people may encounter at some point in their driving lives. While it may seem daunting at first, it's a manageable process that can be done with the right tools and a bit of know-how. Luckily, there are kits available to do this which contain everything you need, including instructional information on how to perform the task.

This article will give you a basic outline for how to fix chips in your windscreen and, while some of the kits will vary slightly from this procedure, they all produce the same result in the end which is fixing the crack or chip.

Do I Need To Fix Chips in My Windscreen?

Fixing chips in a windscreen is important for several reasons, all of which contribute to the safety, structural integrity, and longevity of the vehicle.

Prevention of Further Damage

Chips in a windscreen have the potential to develop into larger cracks over time, especially if they are subjected to changes in temperature, pressure, or road vibration. By repairing chips promptly, drivers can prevent them from spreading and causing more extensive damage to the windscreen.

Safety of Occupants

A damaged windscreen compromises the structural integrity of the vehicle and may fail to provide adequate protection in the event of a collision or rollover. Fixing chips helps to restore the strength and stability of the windscreen, ensuring it can withstand impact forces and protect occupants in the event of an accident.

Clear Visibility

Chips and cracks in a windscreen can obstruct the driver's view of the road, potentially leading to accidents or collisions. Repairing chips restores the clarity of the windscreen, allowing for unobstructed visibility and safer driving conditions.

Legal Compliance

Depending on your state and the size of the chips, driving with a damaged windscreen is a violation of road safety regulations and may result in fines or penalties. Repairing chips promptly ensures compliance with legal requirements and helps drivers avoid legal consequences associated with driving with a damaged windscreen.

Cost Savings

Repairing chips is often more cost-effective than replacing the entire windscreen. By addressing minor damage early on, drivers can avoid the expense of replacing the windscreen and the inconvenience of scheduling a windscreen replacement appointment.

Tools for the Job

• Resin
• Curing strip
• Syringe/applicator
• Razor blade
• Clean cloths
• Rubbing alcohol

Assess the Damage

Start by examining the chip in your windscreen to determine its size and severity. Chips smaller than a 5-cent coin are usually repairable, while larger chips or cracks may require professional attention.

Take note of any cracks extending from the chip, as these can compromise the integrity of the windscreen. It is best to fix them as soon as practical as if it gets dust or dirt in the crack, it makes the repair more visible.

Clean the Area

Park the car in the shade, out of direct sunlight. Make sure the windscreen is cool. Use a clean cloth and rubbing alcohol to thoroughly clean the area around the chip. This will remove any dirt, debris, or oils that could interfere with the repair process. Allow the area to dry completely before proceeding.

Prepare the Chip

If there are any loose glass fragments or debris in the chip, carefully remove them using a razor blade or scraper. Be gentle to avoid widening the chip or causing further damage to the windscreen.

Apply the Repair Resin

Open the windscreen repair kit and follow the instructions to inject sealant into the chip. It takes a little setting up though it is not difficult. Once the resin is injected wait 5 to 10 minutes. If the chip is not fully covered repeat the process until the chip is covered by resin.

Place the Curing Strip

Once the chip is filled with resin, place the curing strip over the top. Add a few drops of resin under the strip. This helps smooth out any imperfections and sticks the strip to the windscreen. It also prevents excess resin from leaking out during the curing process.

Cure the Resin

Most windscreen repair kits include a UV light or sunlight-curing resin. Position the windscreen so that the repaired area is exposed to direct sunlight or use the UV light according to the kit's instructions. Allow the resin to cure completely, typically for 10-15 minutes.

Remove the Curing Strip

After the resin has cured, carefully remove the curing strip from the windscreen. Use a cutting tool like a razor blade or scraper to gently scrape away any excess resin or cured material from the surface of the windscreen.

Inspect the Repair

Once the repair is complete, inspect the area closely to ensure the chip has been properly filled and sealed. If necessary, repeat the repair process to fill any remaining voids or imperfections.

Clean Up

Dispose of any used materials properly and clean up any spills or excess resin from the windscreen and surrounding area. A final wipe with rubbing alcohol can help to remove any residue and leave the windscreen looking clean and clear.

Seeking Professional Help With Larger Chips

It is important to remember that not all chips can be repaired, especially those that are large or located in the driver's line of sight. If you're unsure whether a chip can be repaired or if you are uncomfortable attempting the repair yourself, it is best to seek professional assistance from a qualified windscreen repair technician.
