Have a Chipped or Cracked Windshield? Learn How to Fix It Yourself

It can be very frustrating to get a chip or crack in your windshield while driving. That is because even small damage to a windshield can expand into a large crack over time. This typically happens when a crack is not repaired quickly enough. A bumpy dirt road, water, and debris can all cause a crack to expand after the initial damage forms. Thankfully, you can repair a crack on your own to prevent it from getting worse.

Tools and Materials

You can get started by gathering the following tools and materials:

  • Razor blade or pushpin
  • Rubbing alcohol
  • Gauze
  • Credit Card
  • Shop vacuum
  • Mild cleaning detergent
  • Windshield crack repair kit

Cleaning the Windshield

The part of the windshield that is damaged will need to be cleaned before attempting any kind of repair. It helps to park your car in an area that is shaded to reduce glare from the glass. Use the corner of your razor blade, or a pushpin, to remove the small glass splinters that are inside the chip or crack. You can use your shop vacuum to remove any tiny pieces of glass or debris when you are finished.

Clean the surface of the windshield using a mild cleaning detergent, such as dish soap and water. Once the surface has dried, you need to clean the area again by rubbing it with alcohol that has been applied to a clean gauze. This step helps the resin adhere to the glass once it is applied in the next step, and it also removes streaks left from the mild detergent.

Filling the Chip or Crack

A windshield crack repair kit will have the necessary items to repair the damaged area, along with thorough instructions. The kit includes a small apparatus that has multiple suction cups and that will attach to your windshield to help you apply the resin that fills in the crack. You'll carefully line up the apparatus over the damaged area and then use the kit's included pump to apply the resin. Remove the suction cup apparatus when finished.

Finishing Work

The repair kit will also come with a finishing film, which helps smooth out the resin on your windshield. Following the kit's instructions, place the film on top of the resin and scrape the film with a smooth, flat surface, such as your credit card. You can then peel off the finishing film. Be sure to move your car to an area where it will get direct sunlight to help the resin dry.

Is your crack too large to repair on your own? In that case, you will need to take it to a local body shop that can repair the damage for you. Look for car repair by Bare's Paint & Bodyworks or seek help from other shops in your area.
