The son of a Kentucky frontiersman, Lincoln had to struggle for a living and for learning. Five months before receiving his partyâs nomination for President, he sketched his life: âI was born Feb. 12, 1809, in Hardin County, Kentucky. My parents were both born in Virginia, of undistinguished familiesâsecond families, perhaps I should say.
All you need to do is leave the grout to dry before getting it wet. The instructions should tell you for how long. As you and others have pointed out drying and curing are separate things. While you can use the shower after the grout is dried you may need to leave it for a day or two after it's cured before sealing.
And you can start using the shower the day after you caulk. When it comes time to seal the grout, just clean it well and let it dry before sealing. The longer you wait before sealing, the more chance of it getting stained, but just using it for a shower (no food prep) is relatively low risk.
