Removing Small Cracks from Windshields: Preparation and Assessment
Understanding the Types of Windshield Cracks
Before attempting to remove small cracks from your windshield, it’s essential to understand the different types of cracks and their characteristics. Windshield cracks can be classified into several categories, including:
- Rock chips: These are small, circular cracks caused by debris hitting the windshield.
- Stress cracks: These are long, thin cracks that can appear due to temperature changes, road vibrations, or other external factors.
- Star breaks: These are a combination of rock chips and stress cracks, often appearing as a star-shaped pattern.
The type and size of the crack will determine the best course of action for removal. In this section, we’ll focus on removing small cracks, typically those less than 6 inches in length.
Assessing the Crack’s Severity
To determine the severity of the crack, follow these steps:
- Examine the crack closely, looking for any signs of spreading or growth.
- Check the crack’s depth by applying gentle pressure with your finger or a soft cloth. If the crack feels shallow and doesn’t change shape, it’s likely a small rock chip.
- Assess the crack’s location, considering factors such as its proximity to the windshield’s edges, the driver’s line of sight, and any surrounding damage.
Based on your assessment, you may decide that the crack is minor and can be repaired at home, or it may be more severe and require professional attention.

Gathering the Necessary Materials
To repair small cracks, you’ll need the following materials:
- Windshield repair kit (available at most auto parts stores or online)
- Clear glass resin
- Hardener (if included in the repair kit)
- Applicator or small brush
- Clean, lint-free cloth or paper towel
- Soft, dry cloth for cleaning the area
- Protective gloves and safety glasses (recommended)
It’s essential to choose a reputable windshield repair kit and follow the manufacturer’s instructions carefully. Some kits may include additional materials or specialized tools, so be sure to read and understand the included documentation.
Preparing the Area and Windshield
Before starting the repair, ensure the area around the crack is clean and free of debris. Remove any loose dirt or debris from the crack using a soft-bristled brush or a clean cloth.
Next, clean the windshield using a gentle glass cleaner and a soft, dry cloth. This will help prevent any dirt or debris from interfering with the repair process.
Now that you’ve prepared the area and windshield, you’re ready to proceed with the repair. In the next section, we’ll cover the steps involved in removing small cracks from windshields.
Removing Small Cracks from Windshields: The Repair Process
Step 1: Cleaning and Preparing the Crack
Using the applicator or small brush provided with the repair kit, apply a small amount of clear glass resin to the crack. Gently spread the resin along the crack, making sure to fill it completely.
Using a clean, lint-free cloth or paper towel, wipe away any excess resin that has oozed out of the crack. Be careful not to touch the surrounding glass, as this can create additional problems.
Step 2: Hardening the Resin
If your repair kit includes a hardener, apply it according to the manufacturer’s instructions. The hardener will help the resin cure and strengthen the repair.
Using the applicator or small brush, apply a small amount of hardener to the resin. Gently spread the hardener along the crack, making sure to cover the entire area.
Step 3: Curing the Resin
Allow the resin to cure for the recommended amount of time, usually several hours or overnight. During this time, avoid exposing the windshield to direct sunlight, high temperatures, or extreme humidity.
Once the resin has cured, use a soft, dry cloth to inspect the repair. If the crack is still visible, you may need to repeat the process or seek professional assistance.
Step 4: Final Inspection and Touch-ups
After the resin has fully cured, inspect the repair again to ensure it’s satisfactory. If the crack is still visible, you may need to repeat the process or seek professional assistance.
Using a clean, lint-free cloth or paper towel, wipe away any excess resin that has oozed out of the crack. Be careful not to touch the surrounding glass, as this can create additional problems.
Finally, apply a small amount of clear glass
