Repair of chipped and cracked windshield



The most vulnerable places of the car are the glass, from which the windshield gets the most impacts from oncoming stones flying out from under the wheels of neighboring cars. To ensure the safety of the driver and passenger, the windshield is made triplex, i.e. it consists of two glass sheets glued together with transparent organic glue PVB (polyvinyl butyral). This structure allows the glass not to crumble when damaged, but to remain in place due to the adhesive layer.

Thus, when road stones get on the windshield, it receives various damages in the form of cracks and chips, which can have a different structure and shape. Chipping is understood as such damage when a small part of the glass layer breaks off from the surface. Small chips could be ignored if they did not lead to the appearance and growth of cracks.
Car windshield repair process
The glass of the car constantly experiences internal and external mechanical stresses under the influence of temperature changes, vibrations that occur during the movement of the car on uneven roads. Therefore, the repair of chips and cracks on the windshield should be done immediately after the appearance of damage, without postponing it in a long box.
To determine the order of further actions, it is necessary to determine the type of damage and its depth. Not all types of windshield damage should be eliminated, as the cost of repair can cost more than replacing the damaged glass with a new one. If both the outer and inner sides of the glass are damaged, then its dismantling will be required for repair, which also complicates and increases the cost of work. Carefully inspect the damage on both sides and proceed to repair, making sure that only its outer layer is damaged.

At first glance, the damage on the glass may seem insignificant. However, over time, from the vibration of the car body when driving, the problem area expands quite quickly, the cracks branch and subsequent repairs will become more expensive.
