Windscreen repair

Types of windscreens repair

Windscreen repair can be done in various ways depending on the severity of the damage and the type of glass used in the vehicle. The most common types of windscreen damage that can be repaired include:

• Chips

  Chips are small, round dings that create a hole in the glass surface. They are usually caused by small stones or gravel hitting the glass. Chip repair is the simplest and quickest type of windscreen repair. In most cases, a resin is injected into the damaged area and cured using UV light. The repaired chip is polished to restore clarity.

• Cracks

  Cracks are linear damages that spread across the glass. They can be small or large, depending on how far the glass has been hit. For smaller cracks, the windshield technician will clean the area and inject resin, then use a bridge tool to fill the crack and make it level with the glass surface. Larger cracks are more challenging to repair. In some cases, the entire windscreen needs to be replaced.

• Star breaks

  Star breaks are similar to chips, but multiple small cracks radiate from a central point. Like chip repairs, the resin is injected into the central hole. It is then cured and polished to restore the glass's appearance and structural integrity.

• Half-moon breaks

  Half-moon breaks occur when a small piece of glass is broken off in a semicircular shape. This type of damage is less common but can be repaired in a similar way to chips and star breaks.

• Bull's eye breaks

  Bull's eye breaks are circular dings with a cone-shaped pit on the surface. The repair process is the same as for chips. The technician injects resin and levels it with the glass surface.

• Edge cracks

  Edge cracks are long cracks that start at the edge of the glass. They can be challenging to repair because they compromise the glass's structural strength. In most cases, a technician will need to replace the entire windshield.

• Vertical cracks

  Vertical cracks are long, straight cracks running up and down the glass. Their length makes them more difficult to repair compared to small cracks. Like edge cracks, vertical ones sometimes require full windscreen replacement.

• Combination breaks

  Combination breaks occur when a chip and a crack are present in the glass. Repairing combination breaks is more complex than other types of damage. A qualified technician uses a combination of techniques to fix the chip and stop the crack from spreading. If the damage is too severe, the technician will replace the windscreen.

Specifications and Maintenance of Windscreen Repair

With the increased complexity of modern vehicles, it has become imperative to understand the specifications of windscreens before attempting any repair.

• Windscreen Glass Thickness

  Windscreens are made using two layers of glass and a layer of laminate in between. Each layer of glass is 5 mm thick. The total thickness of the windscreen is 10 mm.

• Quality of Repair Resin

  The resin used during repairs is made to match the quality of the resin used to make the windscreen. This ensures that the repair is as strong as the rest of the glass.

• Quality Control Standards

  Every repair done on a windscreen needs to meet certain standards. These standards are set by quality control organizations to make sure the repair is safe and effective.

• Windscreen Frame

  The area around the windscreen, called the frame, is an important part of the car's structure. It provides support for the windscreen. Repairs must be done carefully so as not to damage the frame.

• Windscreen Adhesive

  The adhesive used to attach the windscreen to the car is very strong. It cures (dries and becomes hard) quickly, so the windscreen can be replaced in a short time.

• Windscreen Design

  Windscreens are designed to be strong and resist damage. They also need to be clear so drivers can see through them easily. The repair process should not affect the glass's strength or clarity.

• Vehicle Safety Standards

  Every vehicle is designed with standards to keep people safe. The windscreen plays a big part in this by supporting the car's structure. Making sure the repair is done correctly is crucial to maintaining the vehicle's safety.

Following the correct procedure when repairing a windscreen is just as important as understanding its specifications. Here are some tips on how to maintain windscreens after repairs:

• Avoid placing adhesive tapes over the repair for at least 24 hours.
• Avoid washing the vehicle using a high-pressure washer for at least 72 hours after the repair.
• Avoid exposing the vehicle to extreme temperatures for at least 24 hours after the repair.
• Avoid removing any protective covers placed on the windscreen during the repair process before the specified time.
• Inform all vehicle users about the repair and the precautions that need to be followed.

How to choose windscreens repairs

Choosing the right tools for windscreen repair can be a difficult task. The market is filled with various tool kits, all claiming to offer the best results. Here are some factors that business owners need to consider before making a purchase:

• Quality of the toolkits:

  It is important to investigate the quality of the toolkits before purchasing. Look for reputable brands that offer high-quality tools for efficient and effective repairs. Quality tools not only provide better results but also ensure durability and reliability.

• Type of stone chip:

  Different types of stone chips require varying repair techniques and tools. Ensure that the toolkit chosen can handle multiple stone chip types and offers versatility in repair methods.

• Ease of use:

  Choose windscreen repair kits that are easy to use and require minimal training for technicians. The repair tools and equipment should be user-friendly, allowing for quick and efficient repairs.

• Cost:

  While cost should not be the primary factor, it is important to consider the value offered by the toolkit concerning the budget. Compare different brands and kits to find the one that offers the best value for money.

• Warranty and support:

  Consider the warranty offered by the manufacturer and the availability of customer support. A good warranty and reliable customer support can provide peace of mind and assistance in case of any issues.

How to DIY and Replace

DIY windscreen repair kits are available for small chips and cracks. The resin is usually injected into the crack or chip using a special applicator. Then, the repair technician uses a UV light to cure the resin, making it hard and preventing further damage.

Here are some simple steps to follow when repairing a windscreen:

• Clean the damaged area

  Use a soft cloth to remove any dirt or debris from the damaged area. Cleaning prevents more dirt from getting into the crack or chip during the repair process.

• Prepare the windscreen repair kit

  Follow the manufacturer's instructions. Fill the repair tool with the provided repair fluid.

• Insert the tool

  Gently insert the tool into the crack or chip. This allows the fluid to get into the damaged area.

• Inject the repair fluid

  Press down on the tool's plunger. This forces the repair fluid into the crack or chip. It also pushes out any air present in the damaged area. Some kits may require the technician to use a small tool to lightly tap on the tool's top. This helps loosen the cracks' or chips' edges.

• Remove the tool and seal the repair

  Once the repair fluid fills the crack or chip, carefully remove the tool. Then, use the provided razor blade to remove any excess material that has oozed out. Finally, apply the kit's sealant over the repaired area. The sealant prevents moisture and air from entering the windscreen.
