Repairing Stone Chips: A Guide

A small stone chip on your car's windscreen might seem like a minor inconvenience, but it's a common issue that many drivers will encounter at some point. The question on many people's minds is: can it actually be repaired? The answer, in many cases, is a resounding yes! At Windscreen Warehouse, we specialise in both windscreen repair and replacement, and understanding when a chip can be fixed is crucial for maintaining the safety and integrity of your vehicle's glass.

Understanding Windscreen Damage

Windscreens are made from laminated safety glass, consisting of two layers of glass with a plastic interlayer sandwiched between them. This construction is designed to prevent shattering upon impact. However, when a stone or other debris strikes the glass at speed, it can cause a small chip or a more extensive crack.

Types of Windscreen Damage

Windscreen damage typically falls into a few main categories:

• Stone Chips: These are usually small, star-shaped or bullseye-shaped marks where the impact has occurred. They often have a raised centre point.
• Cracks: These are linear fractures that can extend from the point of impact. Long cracks (typically over 6 inches or 15cm) are often difficult or impossible to repair effectively.
• Combination Damage: Sometimes a chip can lead to a small crack, or a crack can originate from a chip.

Can a Stone Chip Be Repaired?

Yes, a stone chip on your car's windscreen can often be repaired. Windscreen repair is a process that injects a special resin into the damaged area. This resin is then cured, typically using ultraviolet (UV) light, which bonds the glass back together. The aim is to restore the structural integrity of the windscreen and prevent the chip from spreading.

The Windscreen Repair Process

The process is relatively straightforward and can usually be completed within 30-60 minutes. Here’s a general overview:

1. Inspection: A qualified technician will first assess the damage to determine if it's suitable for repair. Factors such as the size, depth, and location of the chip are crucial.
2. Cleaning: The damaged area is thoroughly cleaned to remove any dirt or debris that could affect the resin's adhesion.
3. Resin Injection: A special clear resin, designed to match the refractive index of glass, is injected into the chip using a specialised applicator. This applicator creates a vacuum to draw out air and then allows the resin to be forced into the damaged area.
4. Curing: Once the resin has filled the chip, it is cured using a UV light. This process hardens the resin, effectively bonding the glass fragments together.
5. Polishing: After curing, any excess resin is scraped away, and the area is polished to a smooth finish. The repair should be virtually invisible and restore the windscreen's strength.

When is a Windscreen Repair Not Possible?

While many stone chips can be repaired, there are certain situations where a full windscreen replacement is necessary:

• Size and Depth: If the chip is too large or too deep, the resin may not be able to adequately fill and bond the damaged area. Generally, chips larger than a £1 coin or deeper than the thickness of the glass are considered unrepairable.
• Location: Chips located directly in the driver's line of sight can obscure vision even after repair, making replacement the safer option. Damage on or near the edges of the windscreen can also compromise its structural integrity, requiring replacement.
• Cracks: Long cracks, or cracks that have spread significantly from the initial impact point, are usually beyond repair.
• Contamination: If dirt, moisture, or other contaminants have entered the chip, it can prevent the resin from bonding correctly, making repair impossible.

Benefits of Windscreen Repair

Repairing a stone chip offers several significant advantages:

• Cost-Effective: Windscreen repair is considerably cheaper than a full windscreen replacement.
• Convenience: The repair process is quick and can often be completed at your location, whether at home or work, minimising disruption to your day.
• Environmental: Repairing a windscreen is more environmentally friendly than replacing it, as it reduces waste.
• Safety: A repaired chip restores the structural integrity of the windscreen, ensuring it functions as intended in the event of an accident, particularly in protecting occupants during a rollover.
• Legality: A damaged windscreen can lead to an MOT failure and may result in a driving ban if it significantly impairs visibility. Repairing chips keeps your vehicle legal and safe.
