For a relaxed and correct driving it is important to have good visibility.

Problems such as glass wear, impacts and splinters prevent having an adequate perception. Some of these damages are solved by repairing the surface of the glass with the use of new technologies.

The cars leave the terminals with laminated windshields, formed by two layers of glass that contain a sheet of plastic inside. In case of impact, it absorbs energy, so it is called safety.

However, if the crystal receives a blow, a mark or cracking may occur. Over there the windshield begins to be damaged much more and breaks if exposed to a sudden change in temperature or subjected to a strong vibration.

The area of ​​the windshield that is most sensitive to a crack is that which is close to the edges (a band of 10 cm around them), since a small splinter can become a crack; it slits first towards the edge and then towards the center, by the movement that the body transmits.

Among the most frequent damages there are two large groups according to the shape they adopt on the surface of the glass: bull’s eye, of circular shapes, and star, because they form ramifications.

How it is repaired

There are several ways to perform the windshield arrangement. One is done with computerized machines that determine the type of blow, as well as remove all traces of ground glass and dirt that has penetrated the outer layer of the windshield. Then it injects into the hole left by the blow a resin that has the same optical and strength characteristics as glass. This product is forged with ultraviolet light and the aesthetics of glass is recovered between 80 and 95%. Due to the pressure exerted by the machine, the liquid reaches the last corners and, at the end of the zone, it is covered with a sheet that dries and solidifies to give the glass an original spare appearance.

Another process is the manual, which from the point of impact drills the first layer of glass with a lathe without touching the plastic, later extracted the air contained with a tool that makes vacuum on the break and injects the resin.

When there are long cracks a tool is used that presses from inside the glass and opens a cut on the surface. With an applicator, the crack is filled; by capillary action, the viscous liquid column displaces the air. No additional perforations are made to fill the cut, preserving the aesthetics.

It is advisable that the repair is made immediately after the blow is suffered, as the breakage grows over time and inside are deposited dirt particles, dust and soot, which are more expensive to remove.

If the service is required, some companies do it at home.

The glass that admits repair is the laminate. However, keep in mind that if the damage is greater than 50 cm or is in an area that makes it difficult to visualize it is convenient to replace it.
