How to seal a crack in the windshield of a car

Damage to the windshield of the car is expressed by cracks, chips and even holes. Sometimes it happens because of the conditioner turned on in the heated car, as a result of temperature difference. But more often than other occur mechanical damage from hitting stones during the passage of oncoming cars. How to cope with this disaster and can it be done by hand?

Today in the Chinese sites you can find ready-made kits to eliminate defects on the windows. Their quality does not always match the claimed, although they cost an order of magnitude cheaper and are sold in sets with tools. Branded polymers for auto glass cracks, such as Pit Filler, Long Crack or Delta Kits, give a better and longer lasting effect. The problem is in most cases solved, but it is necessary to correctly apply such a restoration.Let's take a look at what professionals advise on this.

Necessary funds and tools

Materials:
  • Specialized polymer of different viscosity;
  • Set of translucent celluloid plates.
Tools for car glass restoration:
  • Diamond drill conical drills;
  • Scriber for marking holes;
  • Scraper blade;
  • Crack extender (suction pad on the rail);
  • UV lamp.

Preparatory work before restoration

Before you begin to seal defects on glass, you need to diagnose them. The best solution would be to turn to a professional master for advice on whether to start this business at all or better to get a new windshield and not spend money on expensive polymers and tools. All factory brand windshields are made of triplex and are labeled with L or WL. Their main damages are as follows:
  • Chips;
  • Potholes;
  • One-sided cracks are just outside the glass;
  • Bilateral cracks - on both sides of the glass;
  • Radiation-shaped cracks - “star” or “gossamer”.A crack goes from one point to different sides or along a circle;
  • Combined defects - a combination of several types of cracks, gouges, chips, etc.
Only a professional master, after analyzing the defect, can confidently say how much the crack will be repaired, what will remain visible and how much material will be needed for work.

Fill the crack on the windshield with your own hands

The defect, by the example of which we Today we consider the restoration of glass, refers to the combined and fairly common. In the lower right corner there is a point of impact, and as a result, a pothole like a horseshoe or a bull's eye. A one-sided crack leaves it. Before the main work, a set of measures was carried out to stop it at the extreme point. The hole was drilled with a drill, and it was filled with a special injector under pressure. The next sequence for pouring with polymer is the following: first the crack itself is filled, then the stopping point and then the impact point. Before work it is necessary to thoroughly wipe the pouring area with a clean rag dry. If necessary, use detergent. How to seal a crack on the windshield of a car
Carefully fill the crack from the polymer bottle as you move from screen printing to the stop and fix the crack.

If the crack is well opened, and does not require the use of a dilator, it can be filled with polymer. In some places, the polymer can remain on the surface without entering the crack. The problem can be solved by pushing from the back of the glass. To do this, you need to squeeze out the glass from the cabin side, slightly pressing your finger on the place of stagnation. The effect of seepage polymer should manifest immediately.

To a fragment of a crack filled with polymer,did not get air when pushing the glass, you must immediately seal it. To do this, we lubricate the celluloid strip with a polymer, and cover it with the treated surface. This material should be cut into small strips 5-7 cm long so that it is convenient to use them.

Fill the polymer with a continuous solid line, so as not to leave blind spots, which can subsequently be filled with air. The possible formation of microbubbles is clearly visible in the light. Such zones should be re-passed polymer, if necessary, forcing the reverse side of the glass.

Also, during the use of the polymer, it should not be allowed to dry on a non-fully filled surface.This can lead to irreparable consequences, and reduce all work to naught. Around the final zones, which are fixed in advance, it is most difficult to expel air from the crack. You have to push glass very carefully here. There is a big risk that the crack will simply go on by adding a good amount of work.

If everything went well, the crack should be as transparent and invisible from different viewing angles. After that, expose the UV lamp, and dry the polymer with the plates.

Remove the dried plate one by one, prying their scraper. To avoid visible sealing defects, it is necessary to scrape the polymer residues strictly along the crack direction.

The quality of the seal of cracks in auto glass depends on many factors. However, on the recommendation of the masters, in most cases, excessive defects can be minimized, saving on the cost of new glass and its installation on your car when it is in service.
