How to Repair Chipped Car Windscreen

A chipped car windscreen can be a nuisance, obstructing your view and potentially worsening over time. Knowing How To Repair Chipped Car Windscreen is crucial, both for safety and to prevent a costly full replacement. This guide will provide you with a comprehensive understanding of chipped windscreen repair, from identifying the damage to carrying out DIY repairs and knowing when to seek professional help.

Identifying the Type of Windscreen Chip

Before attempting any repair, you need to identify the type of chip you’re dealing with. Different types of chips require different approaches. Common types include bullseye chips (circular with a small central point of impact), star breaks (small cracks radiating outwards from the impact point), combination breaks (a mix of bullseye and star break characteristics), and long cracks. Understanding the type of chip is the first step in determining the best course of action.

The size and location of the chip also play a crucial role. Chips smaller than a quarter and not in the driver’s direct line of sight are usually repairable. Larger chips, long cracks, or chips located in the driver’s field of vision often necessitate a full windscreen replacement.

DIY Windscreen Chip Repair: A Step-by-Step Guide

For minor chips, a DIY repair kit can be a cost-effective solution. These kits typically contain a resin, an applicator, and a curing strip. Follow these steps to repair a chipped car windscreen:

Clean the chipped area thoroughly with glass cleaner and a lint-free cloth.
Attach the applicator over the chip, ensuring a tight seal.
Inject the resin into the chip using the applicator.
Apply the curing strip over the resin.
Allow the resin to cure in direct sunlight as per the kit instructions.
Carefully remove the curing strip and any excess resin with a razor blade.

While a DIY repair can be effective for small chips, remember it might not completely restore the windscreen’s original clarity.

When to Call a Professional

While DIY kits can be helpful for minor chips, there are situations where professional intervention is necessary. If the chip is larger than a quarter, located in the driver’s line of sight, or if the crack is long or deep, you should consult a professional. Attempting a DIY repair in these cases can potentially worsen the damage and compromise the structural integrity of the windscreen.

Furthermore, if the chip is close to the edge of the windscreen, a professional repair is recommended. The edges of the windscreen are under more stress, and a DIY repair might not be strong enough to withstand this pressure. A professional will have the necessary tools and expertise to carry out a more robust repair.

Professional Windscreen Chip Repair: What to Expect

Professional windscreen chip repair involves similar principles to a DIY kit, but with more advanced tools and techniques. Professionals use specialized resins and vacuum systems to ensure a more complete fill and stronger bond. They can also repair chips closer to the edge of the windscreen, which is often beyond the scope of DIY kits.

The cost of professional repair varies depending on the type and size of the chip, but it’s generally much cheaper than a full windscreen replacement.

Preventing Future Windscreen Chips

While not all chips can be prevented, you can take steps to minimize the risk. Maintain a safe following distance, avoid driving on gravel roads when possible, and replace worn wiper blades regularly. These simple precautions can help protect your windscreen from flying debris and reduce the likelihood of chips and cracks.

Conclusion

Knowing how to repair chipped car windscreen can save you both time and money. While DIY kits offer a convenient solution for minor chips, it’s essential to recognize when professional help is required. Whether you choose a DIY repair or consult a professional, addressing a chipped windscreen promptly is crucial to prevent further damage and ensure safe driving.
