Wait until 24 hours for the grout to cure completely.
Step Four: Time to dry buff!
Once the grout is completely dry after 48 hours, we recommend applying a grout sealer.
Silicone won't stick to wet or even damp grout. It may last the day but it won't last long after. If using a non-silicone such as CT1 then if SPOTLESSLY clean and grout residue free you could seal the same day but not directly after.
The ideal moment to seal grout is after the tiles are completely fixed and the grout has had a chance to dry. Generally, tiles take around 24 hours to fix, but waiting at least 48 hours before sealing is advisable.
After putting new Grout, you need to wait for 16 hours before you disturb it. The curing take a long time (one month or longer). For full strength, you need to keep the grout wet at least for 3 days. To leave the grout to dry in 3 days, is not a good idea. Usually, you need to mist it for 3 days.
However, a common guideline is to wait approximately 15 to 30 minutes after applying the grout before wiping off the excess. This initial waiting period allows the grout to firm up and achieve a workable consistency.
If you don't allow the mortar to cure thoroughly before you start grouting, your tiles may dislodge or move around down the road, leading to uneven surfaces.
While the initial drying process may take several hours, the curing process can span days, weeks, or even months, depending on various factors. It's not uncommon for grout to achieve its maximum strength potential only after 28 days of continuous curing under ideal conditions.
You may be wondering if it's possible to put silicone over grout. We've done our research and this is what we found out. Yes, you can put silicone over grout. This ensures watertight sealing.
It is important not to leave any excess sealer on the tile surface because it won't get absorbed and it can leave a sticky surface that can become a maintenance problem.

Grout Must Set and Cure
Then the grout needs to be cured for a couple of days. That usually takes between 48 and 72 hours. If you can avoid walking on your floor for that amount of time, that would be ideal.
The standard cement grout commonly found in most hardware stores and used in most residential homes takes around 48-72 hours to cure. But it is worth pointing out that you need to know how to mix grout the right way. If too much water is added it will obviously take longer to dry and won't do its job as well.

Although silicone or caulk sealants get touch dry within an hour and won't attract dust or debris, it is advisable that you wait longer before exposing them to water. When applying silicone sealant on a shower, it's recommended to wait at least six hours, but waiting for a full cure is best, which takes about 24 hours.
You don't necessarily have to remove all of the grout but I would remove enough to recess it back under the wall tile to give some room and a place to adhere the new caulk. For best appearance, you want the caulk to mimic the look of the existing grout.
It's a common question among newer DIYers: Should I use grout or caulk in the shower? The answer: Both. Use grout between the tiles, whether they are on the floor or wall. Use caulk at the corners of the walls and in the joints where the shower wall meets the floor or wall.
Caulk seals seams and cracks around the home and keeps them waterproof. Before painting or using the area, you'll want to know how long it takes for caulk to dry. Caulk takes two to four hours to dry before painting and is fully cured in 24 hours.
We recommend waiting for at least 48 hours after installing a grout before you apply a sealer. Older grout should be cleaned thoroughly before being left to dry. Make sure to protect grout from spills and stains during this time, otherwise you'll be sealing in the dirt instead of keeping it out!
The typical cement ground found at most hardware stores takes 48 to 72 hours to dry. It's tempting to touch grout to see if it's dry, but try to resist. That said, you'll likely notice that wet grout is much darker than dry.
It is recommended to wait 3 days before using the shower.
The shortest time after laying tile that you can grout is 24 hours.
Grout is used to fill the gaps between walls, usually tiles, so that they stick together. For grout to work its magic, it should be left to dry for a reasonable amount of time; otherwise, all your efforts will be ruined. On average, grout takes around 24-72 hours to dry.
Generally speaking, grout requires 15 to 30 minutes at minimum to set before wiping away any excess, but there are a few things to know about the material before you reach the point of sponging it.
