Two to Four Hours
Your vehicle should be allowed to sit for two to four hours after windshield installation, according to RV Glass Solutions. This estimate is enough time for urethane to dry and the windshield to set. Having your window replaced on a warm, dry, day is also recommended.
Don’t Rush It
According to Capitol Glass Works, glass installation requires a full 24 hours before drive away is recommended. Hurrying the set time on a windshield replacement is a safety issue, so it’s best to avoid rushing for mere convenience.
With today’s quick drying urethanes and mobile businesses that will replace your windshield in a parking lot while you work, it is unnecessary to wait longer than two to four hours for your new windshield to sit before driving.
