¿Cuál es el Procedimiento para Reparar la Luna de un Coche? | Ralarsa

A car is permanently exposed to all kinds of risks that can damage the windscreen. Therefore, to avoid accidents or unpleasant surprises, it is essential to have a car window in perfect condition. However, there is always the possibility that the windscreen may crack or be damaged due to a strong impact.

If it has been damaged, it is necessary to have it repaired by the best specialists, such as Ralarsa, with more than 40 years of experience. For this purpose, you can opt for car window repair or windscreen replacement, depending on the type of damage. Although both processes guarantee a glass in perfect condition, windscreen repair offers certain advantages. At Ralarsa, a workshop specialising in replacement and repair of glass for all types of vehicles, we explain the procedure for repairing a car windscreen and what advantages it offers compared to replacement.

When is it possible to repair a windscreen glass?

Cracks or chips in a car window can be repaired provided that:

  • The damage has a diameter smaller than 40 millimetres — about the size of a two‑euro coin.
  • The crater of the hole is smaller than 5 millimetres.
  • The damage must not affect the layers located inside the glass.
  • The impact is outside the driver’s field of vision and not too close to the edges.

If any of these requirements are not met, the best option will be windscreen replacement.

In any case, as soon as you detect any damage to your car window, it is advisable to go to a workshop specialising in car windscreen repair and replacement. The qualified technicians at Ralarsa will advise you in the best way regarding any incident involving your car window.

Procedure for repairing a car windscreen

Windscreen repair is a good option to restore your car window quickly and easily. Below, we explain step by step how it is carried out at Ralarsa workshops:

  1. Prepare and clean the damaged area. Ralarsa’s specialist technicians first prepare and carefully clean the damaged area of the car window, protecting the vehicle’s different elements beforehand to avoid any damage.
  2. Empty and fill the crack with resin. Using a special state‑of‑the‑art tool, all air inside the crack is extracted and then a colourless resin is injected to fill the entire affected area of the windscreen.
  3. Dry the resin until it hardens. An ultraviolet light is used to dry the resin.
  4. Remove excess and polish the treated area. Once the resin is completely dry, any possible excess material is removed and, finally, the entire affected area is polished to achieve a smooth surface and a high‑quality car window repair.
  5. Clean the windscreen and deliver it in perfect condition. In some cases, a small residual spot may be visible, but the impact will be repaired.

In addition, if you have already had a windscreen repair and your car suffers damage again, it should be noted that it is possible to repair a car windscreen several times as long as the impacts or damage occur in different areas. At Ralarsa we offer top‑quality car windscreen repair!

Advantages of car window repair

Repairing a car’s windscreen offers a variety of notable advantages compared to fully replacing the glass. Repairing laminated glass in a car window is intended for minor damage and is therefore a much quicker and easier process than windscreen replacement — a factor that represents a considerable time saving. Generally, repairs at Ralarsa workshops are completed in approximately 30 minutes.

Among the most relevant advantages of repair, it is worth noting that it is a sustainable process that significantly reduces environmental impact. Because laminated glass is very complex and costly to recycle, replacing a car window generates far more CO2 emissions than a repair. Furthermore, if you have car glass insurance, windscreen repair does not affect your policy’s no‑claims bonus.
