grout cure time
I just got done grouting the new tile in my shower. The label on the unsanded grout says it can't be flooded with water for 21 days. What does that mean? I know the wall tiles won't be under water but expect water would run down them during a shower. How long do I need to wait before using the shower?
If I remember the last tub surround/shower I did [only one] I used the shower the next day although that was close to 35 yrs ago.

We just regrouted ours a few months back and I think we just waited a couple days. I think it said to wait 24 hours to put the sealer on and then another day after that, altho not 100% sure if we had to wait after the sealer. Anyways, the grout did fine.

Grout needs to cure 72 hours before sealing. Seal with a quality grout sealer. Test, if the grout darkens when moisture is applied, then you need to reseal.

This is the grout I used - https://www.lowes.com/pd/MAPEI-10-lb...-Grout/1119247 [not premixed]

Yep, 72 hours and then seal. You used the right stuff, Mapei makes excellent grouts and mortars. My go to brand for most all projects.

I think by immersion they must mean "submerged in water" like the bottom of a pool or tub would. Says in the instructions right before that its ok for residential use after 72.

You won't like the price, but this is my go to sealer. Can be found at that big orange store.

I had used water. I found out after the fact that there is a liquid you can mix with the grout so you don't need to seal. I waited 72 hrs for the grout to dry, sealed and waited another 72 hrs before putting the shower in service. I bought a 6 oz bottle of grout sealer at Lowes which was enough to do both the shower and the bath rm floor.
