Very often the windshield of a car receives mechanical damage as a result of a stone or other object falling on it. Cracks are also formed due to strong changes in temperature, usually due to the fact that the air conditioner is turned on in the heat. The cost of repairing a crack or broken glass is much cheaper than the cost of completely replacing it.
Instructions
Step 1
If the damage is not very large, you can remove it with special glue. To do this, pour the material into the crack until the edges are even. Then dry the affected area using a special ultraviolet lamp. Then carefully buff the area next to the crack. As a result, it will disappear almost without a trace. Only those who knew that any manipulations were carried out with the car will be able to find traces after such a repair.
Step 2
In auto repair shops, shallow chips and cracks are repaired using special photopolymers. First, they process the resulting cavity, and then dry them with devices that are designed to work with these materials. As a result, the crack is no longer visible. Keep in mind that surface cleanliness is the key to the success of removing damage completely. If dust and dirt get into a scratch or chip, even after the most careful jewelry processing, the place of repair can still be seen.
Step 3
To stop the further propagation of the crack and prevent it from growing in different directions, it is necessary to carefully define its boundaries. And then drill around the edges. Next, upload the repair material, after the complete crystallization of which, polish the glass.
Step 4
Experts recommend removing chips up to three centimeters deep and cracks no more than thirty centimeters long. Any other damage will irreparably damage the windshield. And from such huge scratches, even as a result of their complete sealing, new rays are more likely to disperse. Therefore, if the windshield is badly damaged, replace it as a whole. It is also worth adding that the repair of large cracks greatly spoils the physical qualities of the glass - this is both a decrease in the surface reflectivity and a deterioration in visibility. And these consequences, in turn, will lead to the fact that you will not be able to drive safely, and there will be a risk of incurring even more trouble.
