DIY Windshield Chip repair: Step-by-Step Guide

Having a chip or crack in your windshield can be frustrating and potentially dangerous. Not only does it obstruct your view while driving, but it can also weaken the structural integrity of the glass. While it’s always recommended to seek professional help for windshield repairs, there are instances where a DIY approach can be a temporary solution. In this step-by-step guide, we will walk you through the process of repairing a windshield chip on your own. However, it’s important to note that this guide is not a substitute for professional repair, and it’s always best to consult with a certified technician for a permanent fix.

Gather the Necessary Tools and Materials

Before you begin the windshield chip repair process, it’s essential to gather all the necessary tools and materials. Here’s a list of items you’ll need:

  • Windshield repair kit: This typically includes a resin, applicator, curing strips, and a razor blade.
  • Clean cloth or towel
  • Isopropyl alcohol or glass cleaner
  • Protective gloves
  • Masking tape
  • Scissors
  • UV light or sunlight

Once you have all the required tools and materials, you’re ready to move on to the next step.

Clean the Chip and Surrounding Area

Before applying any repair materials, it’s crucial to clean the chip and the surrounding area. This ensures that the resin adheres properly and improves the overall effectiveness of the repair. Follow these steps to clean the chip:

  1. Use a clean cloth or towel to remove any loose glass fragments or debris from the chip.
  2. Apply a small amount of isopropyl alcohol or glass cleaner to another clean cloth or towel.
  3. Gently clean the chip and the surrounding area to remove any dirt, grime, or oils.
  4. Allow the area to dry completely before proceeding to the next step.

By thoroughly cleaning the chip, you ensure that the repair materials bond effectively and increase the chances of a successful repair.

Prepare the Windshield Repair Kit

Now that the chip and surrounding area are clean, it’s time to prepare the windshield repair kit. Follow these steps:

  1. Put on protective gloves to avoid any contact with the resin.
  2. Open the windshield repair kit and familiarize yourself with its contents.
  3. Take out the resin and applicator from the kit.
  4. Attach the applicator to the resin tube according to the manufacturer’s instructions.
  5. Ensure that the applicator is securely attached to the resin tube.

Once you have prepared the windshield repair kit, you’re ready to move on to the next step.

Apply the Resin to the Chip

Now comes the crucial step of applying the resin to the chip. Follow these steps carefully:

  1. Place a small amount of resin on the chip using the applicator.
  2. Ensure that the resin completely fills the chip and covers any cracks or fractures.
  3. Use the applicator to spread the resin evenly over the chip.
  4. Apply slight pressure to the applicator to force the resin into the chip.
  5. Continue applying the resin until the chip is completely filled.

It’s important to note that the resin should only be applied to the chip and not the surrounding glass. Applying resin to the glass can result in a hazy or discolored appearance.

Cure the Resin and Remove Excess

After applying the resin, it’s time to cure it and remove any excess material. Follow these steps:

  1. Place a curing strip over the resin-filled chip.
  2. Ensure that the strip covers the entire chip and extends slightly beyond its edges.
  3. Expose the curing strip to direct sunlight or use a UV light to cure the resin.
  4. Follow the manufacturer’s instructions regarding the curing time.
  5. Once the resin is fully cured, carefully remove the curing strip.
  6. Use a razor blade to scrape off any excess resin from the surface of the windshield.
