How long after replacing the windshield can the car be used normally?

Since the windshield is fixed with glass adhesive, which has a curing time, the time required before driving depends on the adhesive's hardening period. The car can be used once the adhesive has hardened and secured the glass. Some glass adhesives are fast-drying and can harden to fix the glass in about 1-2 hours, while others may take around 6 hours to cure. More information about glass adhesive is as follows: 1. Currently, the curing temperature requirements for ordinary adhesives on the market are around 5-40 degrees Celsius, and the time to achieve safe driving is after 24 hours. Therefore, it is also necessary to consider the quality of the glass adhesive and seasonal factors. 2. Generally, after replacing the windshield, a water leakage test is usually required to check for any leaks.
I remember last time my car also had its windshield replaced, and it's generally recommended to wait more than 24 hours before driving normally. This is mainly to allow the adhesive to fully cure, otherwise sudden braking or bumpy roads can easily cause leaks or even loosen the glass. Once, I drove on the highway the same day after replacement, and the wipers made squeaking noises—it turned out to be water seepage at the edges due to the adhesive not drying completely. In hot weather, the adhesive dries faster, and you might be able to drive short distances after 24 hours, but in winter, you need to patiently wait for 48 hours. Normal use, including operating the wipers, driving at regular speeds, and washing the car, is fine, but avoid washing the car or speeding on the highway on the first full day after replacement. Keeping the windows closed for half a day helps the adhesive set. Safety first—it’s always better to wait a bit longer to avoid rework and extra costs.
