Press the sink firmly into place for 24–48 hours to allow full curing. Avoid placing weight on the sink during this period. For best results, use a caulk gun to apply adhesive precisely, minimizing mess and ensuring a clean finish. Follow manufacturer instructions for drying time and curing conditions.
