Even though your shower grout looks dry, using it too early or sealing it before it's ready may damage it, leading to premature failure. Most cement-based grouts require a cure time of 48 to 72 hours before applying a penetrating sealer.

Each sealer has their own recommendations as to how long to wait before sealing, and I've seen anything from 2- 28 days (full curing time). The good news is most sealers are closer to the 2 day period. Now, as for traffic, you can usually walk across the floor within 3-4 hours, and do work in the room the next day.
