How to Repair Your Windshield




Introduction: How to Repair Your Windshield

If you have a chip on your windshield, it is necessary that you get it repaired as soon as possible. A small chip on your windshield can turn into a big problem quickly. After the first layer of your windshield is penetrated, it is likely to crack out causing further damage, plus the need for a costly replacement.

Repairing your windshield when you notice a chip will save you money in the long run. You can call a windshield repair company, or do it yourself. They do sell inexpensive windshield repair kits at your local auto parts store, but if you are not comfortable with the process, call a professional.

Step 1: Windshield Repair Tools & Supplies

You can purchase a windshield repair kit from your local auto parts store, which will include all the necessary tools and supplies. I will be using a professional grade windshield repair kit, but the concept is the same.

You will need
A Mirror to place on the inside of the windshield
A Bridge & injector
Windshield repair resin
Windshield pit filler
Plastic curing tab
Razor blades
A dremel tool with special glass bit for cracks

Step 2: Beginning the Repair

The first step is to prep the chip and windshield for repair. i recommend using an alcohol pad to clean the area, and gently scribe out any loose glass from the "impact point".

Next, hook your mirror up on the inside of the windshield, centered on the chip you are going to be repairing. This will allow you to keep an eye on the chip from all angles, which is very helpful with all windshield repairs.

Step 3: Make a Seal Over the Chip

You want to center your bridge or whatever tool you are using directly on the chip. You basically want to create a seal over the area of the chip that is missing glass.

Step 4: Drop Resin

After you effectively have created a seal around the chip, put 3-8 drops of resin into the injector area.

Step 5: Injecting the Chip

Next, Use the injector to push the resin into the windshield chip. You should be able to see it start to clear up through your mirror. Keep an eye on it, releasing air and re-injecting the resin when needed. Leave it alone for about 5-10 minutes.

Be sure to keep the area covered if you are in direct sunlight, as you do not want the resin to cure prematurely.

After you have let it sit, and it appears as if the chip has cleared up, you can remove the bridge.

Step 6: Fill in Missing Glass

The Repair is just about complete, but we still need to fill in the "pit" of the chip.

The pit is the area where little bits of glass are missing.

This step will give the glass a smooth finish once again.

Get your pit filler, and drop a tiny bit directly on the impact point. Grab a plastic curing tab, and place over the area. LEave alone in direct sunlight for a minute or so to let it cure.

Step 7: Scrape Off Excess

Grab a razor blade, and hold it securely upright. Scrape off all excess pit filler, leaving only the area where glass was missing filled.

You can even go an extra step and use a light polish on the area to be sure that the area is flush.

Cosmetically windshield repairs clear up anywhere from 30%-80% depending on many variables. Age, Moisture, dirt, location, and temperature all play a roll in the appearance of a repaired windshield chip.

Structurally, the glass should be back up to 100%

    Repairing windshield with Professional kit is a good idea but I don't think we can do it as good as professionals. Nowadays, Professionals are doing it in very reasonable price.

    The injector is kinda not the best. I prefer the ones with it on either side of the chip for even pressure. Where i use to work we did this all the time. The fun part was getting it drilled out right and not hit the other side. So long someone is paient and has a sharp bit it causes no problems. If you can do this within a garage do it. A UV light is also helpful to cure it if it is indoors or out doors. Cures it nice and fast without having to depend if the sun is out.

    @ecramer I don't see any way someone would mess up there windshield worse then the chip in the first place. Maybe too much sealer but the cn be taken off. Also no one will ever learn how to do anything without trying it first.
