In this automotive maintenance how-to article on windshield repair products for your car, we will discuss the process for repairing a crack in your windshield through the use of repair epoxy. The repair epoxy is a product that can seal cracks and prevent them from spreading and causing further damage to the windshield.

The process for using windshield repair epoxy involves cleaning the crack, inserting the epoxy and allowing it to dry in order to seal the crack. This article will describe the process necessary to use windshield repair epoxy including the materials and steps.

Step 1: Purchase a Windshield Repair Kit

You will need to purchase a windshield repair kit from an auto repair store. The kit should contain an adhesive base, syringe, epoxy necessary to repair your windshield.

Step 2: Clean the Crack

Use a pin or small sharp object to clean any loose glass or other debris that may be inside the windshield crack. You need the area to be as clean as possible prior to placing the epoxy inside. Wipe away and loose material before proceeding with the next step in your use of the windshield repair epoxy.  

Step 3: Apply the Epoxy

Attach the base for the syringe that should be placed over the crack in the windshield. Fill the syringe carefully with the epoxy, making sure to leave the cap end on in order to keep from spilling any of the material on your hands. With the syringe filled with the epoxy attach it to the adhesive ring and hold in place in order to apply the solution to the crack.

Depress the plunger on the syringe slowly in order to fill the crack with the repair epoxy. Lock the syringe in place at the vacuum line and hold in place for 5 minutes. Repeat this process several times until all of the epoxy in the syringe has been dispensed, filling the crack and surrounding area completely.

Step 4: Set the Syringe to its Vacuum Setting

With the epoxy completely dispensed on the windshield, use the pin that you used to scrape the crack in Step 2 to lock the syringe in the vacuum position. Hold this position for 3 to 4 hours in order for the epoxy to seal the crack.

Step 5: Remove the Syringe

After the time has elapsed remove the syringe from the adhesive backing that you attached to the windshield. Take a utility knife or sharp razor to scrape off any epoxy residue that remains on the windshield in order to clean the area. Wipe the windshield clean with a rag.

Apply glass cleaner or soap and water to clean the window thoroughly, removing the remaining epoxy debris and adhesive residue that may be remaining on the windshield. Once you have completely and thoroughly cleaned the window, run your fingers around the area where the crack was repaired to make sure that the repair was properly completed.
