No matter how you take care of your "iron horse", no one is insured against damage to the windshield. Annoying chips or cracks impair visibility and spoil the exterior of the vehicle. You have to choose between replacing and repairing vehicle windows. It is clear that the latter option will be cheaper.
Necessary
- - polymerizing composition;
- - drill;
- - special plates;
- - UV lamp;
- - polishing machine;
- - vacuum cleaner.
Instructions
Step 1
Remove glass scuffs and minor scratches by polishing. Keep in mind that repairing chipped car windshields is not performed using this method. Since the formed indentations after the removed layer of glass can cause optical distortion. And this will entail a decrease in traffic safety.
Step 2
Start repairing the chipped windshield of the car in a timely manner, until a deep crack has formed, into which dirt has already clogged. To obtain an internal cavity in the three-layer glass, drill a small hole in the center of the chip. Through this hole, inject a special liquid polymerizing compound under pressure into the resulting cavity. Spread the compound evenly over the entire damaged area.
Step 3
Repairing chipped car windshield involves restoring its transparency up to 95%. The polymer has a refractive index of light close to glass. With good adhesion, it glues the edges of the chip. The air is forced out, the development of cracks is stopped. Apply a thicker compound to the liquid polymer to prevent leakage. Apply special plates to exclude the interaction of the polymer with air.
Step 4
Expose the curing compound to UV light for 20 minutes to cure it. Carefully wipe off excess compound from the glass with a sharp object. The final stage of car glass repair will be polishing.
Step 5
Start repairing cracked car windows by removing dirt and moisture. To do this, use a water-displacing fluid or vacuum cleaner. Next, take measures to prevent crack growth. Drill blind holes at a distance of 6-8 mm from the ends of the cracks. Break the crack down to the hole with a slight pressure. To prevent cracks reaching the edge of the glass from unsticking after repairs, drill additional "shut-off" holes.
Step 6
Fill holes and crack with curing compound. The application of special plates and the irradiation of the adhesive composition with an ultraviolet lamp when repairing cracks in car glass is carried out as when repairing chips. Such a crack will not be enlarged by vibration. Correctly performed crack repair restores the optical transparency, heat resistance, spall resistance and strength of the glass.
Step 7
Clean the interior after repairing car windows by removing small fragments with a vacuum cleaner. Refrain from traveling by car for 24 hours until the glue has completely polymerized.
