If you are looking for home remedies to repair a broken windscreen, you will not find them in this article — but what you will find are solutions and techniques for car glass repair.

The fact is, a tiny chip in the windscreen can turn into a large crack if neglected, making it necessary to use car glass replacement services. You may ask yourself: what can be done to stop a small chip from becoming a large crack? We explain below.

Car glass repair in emergency situations

If we carry out a quick internet search, we can find multiple supposed remedies for car glass repair, such as applying nail polish to the damaged area; however, these are somewhat dangerous practices. These are “emergency” car glass repair tips that could actually put your safety at risk on the road.

To begin with, we must say that a damaged windscreen, if the crack is no larger than a two‑euro coin, does not pose a danger to driving — although it is a type of damage that should be repaired as soon as possible.

While it is true that such cracks may go unnoticed, it is advisable to act quickly as soon as we become aware of the damage. Driving on uneven terrain, poorly maintained roads, or exposing the car to high or low temperature changes could mean that instead of opting for car glass repair, we have to opt for complete car glass replacement.

How to avoid temperature changes?

Cold or heat will cause a stone chip to turn into a crack due to the contraction and expansion of the material in the car glass. The glass expands when subjected to high heat and contracts with cold. Such situations occur when the car remains for a while in an acclimatised area and then returns to the outdoors. To prevent the damage from getting worse, at Ralarsa we recommend parking the car indoors — and if it is summer and there is no possibility of parking inside, it should be parked in a shaded area.
