Car Windscreen Crack Repair Kits

If you own a car, chances are you have experienced the frustration of having a cracked windscreen. Not only is it unsightly, but it can also be a safety hazard and may even result in a failed roadworthy inspection. However, with the advancement of technology, there are now various car windscreen crack repair kits available on the market that claim to be able to fix your windscreen at a fraction of the cost of a professional repair. In this article, we will take a closer look at these repair kits and determine whether they are worth the investment.

Understanding What Causes Windscreen Cracks

Before diving into the different types of windscreen repair kits, it is important to understand the various factors that can cause a crack in your car's windscreen. Some common causes include:

Impact from Debris

One of the most common reasons for windscreen cracks is an impact from debris such as rocks, gravel, or hail while driving. These impacts can create small chips or cracks that can quickly spread if left unrepaired.

Temperature Changes

Extreme temperature changes can also cause your windscreen to crack. This is because glass expands and contracts depending on the temperature, and repeated cycles of this expansion and contraction can weaken the glass and lead to cracks.

Age and Wear

As your car ages, its windscreen can become more susceptible to cracks due to wear and tear. Over time, the constant exposure to sunlight, rain, and other elements can weaken the glass, making it more prone to cracking.

Types of Car Windscreen Crack Repair Kits

There are several types of windscreen crack repair kits available on the market, each with its own unique features. Here are some of the most common types of repair kits and how they work:

Resin-Based Repair Kits

Resin-based repair kits are the most widely used type of windscreen crack repair kits. They typically consist of a special resin that is applied to the crack and hardened using an ultraviolet (UV) light. This process binds the cracked glass together, making it less visible and preventing the crack from spreading further.

Pros:

• Easy to use
• Can be used on both small chips and larger cracks
• Affordable compared to professional repairs
• Can prevent cracks from spreading

Cons:

• May not fully restore the appearance of the windscreen
• Can only be used on certain types of damage
• Requires patience and precision for best results

Adhesive Film Repair Kits

Adhesive film repair kits work by covering the cracked area with a clear adhesive film that seals the crack and prevents it from spreading. These kits usually come with pre-cut adhesive films in different sizes, making it easier to find one that fits your specific crack.

Pros:

• Quick and easy to apply
• Can be used on any type of crack or chip
• Durable and long-lasting

Cons:

• May leave a slight residue on the windscreen
• May not fully restore the appearance of the windscreen
• Cannot be used on very large or complex cracks

DIY Windshield Repair Kits

DIY windshield repair kits are similar to resin-based repair kits but often come with additional tools such as suction cups and syringes. These kits are meant to mimic the same process used by professionals, but at a much lower cost.

Pros:

• Can be used on various types of damage
• Often come with multiple tools for better precision
• More affordable than professional repairs

Cons:

• Requires some skill and patience for best results
• May not fully restore the appearance of the windscreen
• Not suitable for severe cracks or chips

How to Use a Car Windscreen Crack Repair Kit

Regardless of the type of repair kit you choose, there are a few general steps that you should follow to get the best results:

Step 1: Clean the Area

Before starting the repair process, make sure to clean the cracked area thoroughly. This will ensure that there is no dirt, debris, or moisture that could affect the repair.

Step 2: Apply the Repair Solution

Follow the instructions provided with your chosen repair kit to apply the solution onto the cracked area. Be sure to use the proper amount and spread it evenly.

Step 3: Cure the Solution

Depending on the type of repair kit, you may need to use an ultraviolet light or let the solution cure naturally. Follow the recommended curing time for the best results.

Step 4: Remove Excess Solution

Once the solution has cured, remove any excess with a razor blade and wipe the area clean with alcohol.

Step 5: Evaluate the Results

Inspect the repaired area and determine if any further touch-ups are needed. If satisfied, allow the solution to dry and cure completely before driving your car.
