A replacement visit has more than one clock: removing and fitting the glass takes time, and the installed adhesive must reach its specified minimum safe-drive-away time before the vehicle is driven. The second period is a safety instruction, not simply a workshop queue estimate.
Sika publishes different minimum drive-away times for different products and conditions. The product data, temperature, vehicle requirements and installation method matter, so a generic two- or three-hour estimate cannot determine when your car is safe to leave. Ask the installer for the exact time for your vehicle and follow any aftercare instructions.
