How to Fix a Windscreen Crack
A crack in your windscreen doesn’t mean you need a replacement. If you’re wondering how to fix a windscreen crack, the good news is that cracks up to 30 cm can be permanently repaired using the UFIXIT Windscreen Repair Kit.
Designed specifically for Australian conditions, UFIXIT allows you to repair cracks, chips, bullseyes and star cracks yourself, helping restore the strength of the damaged glass and prevent the damage from spreading.
Available at Supercheap Auto, Repco, Autobarn and Amazon, or ask for UFIXIT at your local auto accessory store.
Can you fix a cracked windscreen yourself?
Yes! With the UFIXIT Windscreen Repair Kit, you can repair windscreen cracks up to 30 cm yourself, without the expense of replacing the entire windscreen.
The key is repairing the crack as soon as possible. Road vibrations, potholes and changes in temperature can cause damage to spread, potentially making a repair more difficult or requiring a complete windscreen replacement.
UFIXIT uses a specially formulated repair resin that penetrates the damage before being cured by sunlight, creating a permanent repair.
What type of windscreen damage do you have?
Before starting, identify the type of damage:
Cracks and star cracks: Repaired by applying UFIXIT resin directly into the damage without the applicator.
Chips and bullseyes: Repaired using UFIXIT’s pressure applicator system to inject resin into the damage.
Combination damage: If a crack extends from a bullseye, repair the bullseye with the applicator first, followed by the crack.
This guide focuses specifically on repairing windscreen cracks without the applicator.
What you’ll need to repair a windscreen crack
The UFIXIT Windscreen Repair Kit includes the resin, curing strips and razor blade needed for the repair. You’ll also need a clean, dry paper towel or microfibre cloth and a shaded area to work.
Important: Don’t clean the crack with water, glass cleaner or chemicals, as these can contaminate the damage and affect the repair.
How to fix a windscreen crack in 5 steps
Step 1. Prepare your windscreen
Park your vehicle in a shaded area, such as a garage or carport. Avoid direct sunlight, as UV exposure can cause the resin to cure before the repair is complete.
Gently remove any loose dust or dirt around the damage using a dry cloth.
Step 2. Fill the crack with resin
Using the supplied razor blade, carefully cut the rounded tip off the UFIXIT resin bottle.
Slowly trace along the crack with the bottle tip, allowing the resin to penetrate the damage. Only move forward as quickly as the crack disappears.
Tip: View the crack from a 45° angle to check that the resin is filling the damage.
Step 3. Apply the curing strips
Once you’ve filled approximately the length of one curing strip, place a strip over the repaired section.
Continue applying resin along the crack, covering each completed section with another curing strip. Slightly overlap each strip until the entire crack is covered.
Step 4. Cure the resin in sunlight
Once the crack is completely filled and covered, move your vehicle into direct sunlight.
Leave the curing strips in place for approximately 5–10 minutes to allow the UV light to harden the resin.
If the resin is still wet, reapply the strips and continue curing until completely hardened.
Step 5. Remove excess resin
Once cured, remove the strips and use the supplied razor blade to scrape away excess hardened resin.
Hold the blade at a 90° angle to the glass and scrape until the surface is smooth.
Your windscreen crack repair is now complete.
How long does it take to fix a windscreen crack?
Most UFIXIT windscreen repairs take approximately 45–60 minutes, although more complex damage may take longer.
There’s no need to rush. UFIXIT resin won’t harden until exposed to sunlight during the curing process, so you can take your time to ensure the crack is completely filled before curing.
Why repair a windscreen crack instead of replacing it?
Repairing windscreen damage early can save money, reduce unnecessary glass waste and help preserve your original factory fitted windscreen.
Your windscreen is also an important part of your vehicle’s safety system, contributing to visibility and structural integrity. Repairing cracks early helps maintain the strength of the damaged glass and can prevent the need for an expensive replacement.
Cracks up to 30 cm can be repaired using UFIXIT, although damage that significantly obstructs the driver’s vision or compromises the windscreen’s safety should be professionally assessed.
