The wait time on most grouts is 3 weeks to fully cure but IMO 2 weeks is enough time.
BTW... expensive sealer and cheap sealer = the same thing. The only difference is you may have to apply the cheaper stuff 2 times. If you get the cheaper stuff, apply it, let it dry, drip some water on it. If it beads then youre all set, if it soaks up, you need another application.
Grout takes 3 DAYS to fully cure, not weeks.
AquaMix makes a same day sealer.
And there IS a difference between different sealers. There's some that last only a year and there's some with 15 yr warranties. I like using stuff that has warranty.
Cheap sealer is no good. There have been cases of installers getting health problems due to the use of the spray on sealers. So I'd steer away from those.
