The shortest time after laying tile that you can grout is 24 hours. However, it is much better to wait at least 48 hours before grouting. This is to give the mortar ample time to set and dry before pressure is applied. Choose a nice and dry day to lay your tile.
You can definately do the setting and grouting in the same day. You need to let the tile set up enough so it doesn't pop loose when you grout it. If the tiles stay in place, there are no quality issues with grouting sooner.
The drying time of thin-set will depend on a few factors, including how it was mixed, how much you put down prior to tiling, temperature, and humidity. As a general rule, you should give it a minimum of 24 hours before proceeding to grout your tiles, but it could take as long as 48 hours to dry completely.
When you grout too soon, you may end up with damaged tiles, especially cracked tiles. Not only do cracks look unsightly, they can also allow water to seep underneath the tiles, potentially resulting in mold and water damage.
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.
While it may be tempting to leave the old thinset in place and simply install new tiles over it, this approach is not recommended for several reasons: Surface Irregularities: Old thinset can create an uneven surface, making it difficult to achieve a smooth and level tile installation.
Mistake: Applying too much adhesive can cause tiles to slip or ooze adhesive through the joints. Too little adhesive can lead to weak spots and failed adhesion.
The golden rule is, try as much as possible to avoid small pieces of tile, or, try to keep them hidden. The same basic idea applies to the vertical lines of your job. Try to minimise any small cuts. It is best to start with a centre line and mark along your wall where each vertical joint will occur.
When it comes to floor tiles, starting from the center of the room will make your job easier, and the tiling pattern will be symmetrical. Make sure your pattern is square and before laying your first tile, draw a couple of chalk lines to guide the installation.
To get a perfectly square corner, you want to aim for a measurement ratio of 3:4:5. In other words, you want a three-foot length on your straight line, a four-foot length on your perpendicular line, and a five-foot length across. If all three measurements are correct, you'll have a perfectly square corner.
A good rule of thumb is to clean as you go, working in small sections. This is especially important if the grout application is slow-going. Optimally, no more than 30 minutes should pass for the initial wiping off of excess grout.
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.
It is possible with speed set but I would only do that if I needed to get a kitchen going in a short period. Far cheaper and a better idea to use mastic adhesive and wait a day or so before grouting.
People tend to get them confused, or even think that they're the same thing. Thinset mortar is used to adhere tiles to a surface, while grout is designed to fill the spaces between tiles once they've been installed. Because they fulfill different purposes, these materials have different compositions.
Thinset, on the other hand, is used to install tile over cement, cement/fiber board and anti-fracture/water proofing membranes. It is what makes it possible for tile or stone to stick or bond to the backer board.
If you have decided that your home or office needs a new floor, the most important step is removing the old floor and its adhesive. Unfortunately, you can't simply reapply thinset and install your new floor.

Porous grouts attract water, dirt, oils, etc. While the tile industry does not require sealing, it is always recommended, especially in wet or high-traffic areas. Penetrating sealers are the most commonly used and offer high water, chemical and stain resistance.
Use a dehumidifier: If you installed grout in a humid area such as a bathroom, adding a dehumidifier may help the grout cure more quickly. Remove plants: If you have plants in the room where you installed the tile, remove them while the grout dries to reduce humidity levels.
If the grout is too thin, it may not harden properly. This causes cracks and holes to form.
Mix 1 part vinegar with 1 part water (50:50 solution) in a spray bottle. Then spray the paste on the grout with this solution. Immediately, you should see the paste start bubbling, which indicates that the cleaning process has begun. Remember: Don't use vinegar on marble or limestone.
You'll do far less work when you apply new grout over old grout and you will use less grout. When selecting the grout you want to use, epoxy grout is a good choice. You don't have to remove all of your old grout to apply the new grout. The new grout can be applied right over the top of the existing grout.
