if you mean dry enough to seal, most grout companies suggest about 20 to 30 days.
most grout will dry enough to walk on in a day
24 hours will give it enough time to set up.
You can get grout stain. It will let you make it darker. If you want to change the grout altogether then it can be easily removed, but time consuming. Simple grout removal tools are available at local home stores. Also a oscillating multifunction power tool will make quick work of it. Then re-grout the joints in whatever color you choose. Grout charts are available where grout is sold. Remember grout will look darker when being installed and will dry lighter. Be very careful of making sure everything is clean. Vacuum out old joints with a wet/dry shop vac. If you use a power tool to remove grout have someone follow behind it with a shop vac. Or you will have dust everywhere.
Depending on the tilesetter, but typically a couple days. The floor needs to be prepared and if there was any patching it may need to dry. The tilesetter may want to come back the next day. Then the tile needs to be set and if the tilesetter has good tools that should only take an hour or two. Then the mortar needs to set before the tilesetter can do the grout. Grouting should take most of a day since the grout needs to cure while it is being cleaned. You should not walk on the tile while the grout is setting up and sealing the grout should wait for a few days. The time involved isn't so much a funciton of the size of the tile job, but more a function of the mortar and grout setting times.
As long as it remains dry, you can even wait a month. I usually wait 5-7 days, as I like my tile glue to cure really well. .
All grout dries lighter when dry.but brown grout should not dry white. Check the date of; it might be passed its shelf life. look and see if you bought a light brown grout. You could cut the grout out with a grout rake but this would take ages
14 to 21 days
It all depends on the sealer you used! I use a product called StableCrete that penetrates into the grout joints to waterproof them without leaving a film. Ready for light traffic in four hours. The Grout is what you seal with a ceramic install and not the ceramic!
To replace the decorative tile border on a concrete pool, the pool will have to be drained. The old tile needs to be taken off and a new tile with waterproof grout or concrete can be installed. The pool should dry for a week or so, before it is refilled.
Duraceramic tile will not chip, break or crack like regular ceramic tiles. Manufactured in a 16" square format with scoring, you can cut the score lines to make 4 tiles 8" square. They are best installed in dry residential rooms. This leaves the bathroom out. Use the proper underlayment for the type of floor you are installing Duraceramic tile on. Spread Congoleum Duraceramic tile adhesive on the underlayment using a tile trowel. Allow to dry until tacky, then set the tiles with spacers. Use a roller to press tiles into place, and allow to dry 24 hours. Grout with Congoleum Duraceramic grout.
The gaps found between most tile work are called grout lines. After the tile was set those voids or gaps should have been grouted. Luckily it is never too late to apply the grout. You can get a small box of tile grout from any hardware shore. It's real easy to apply. Just follow the instructions on the box.
Take a wet washcloth with Clorox(the powder kind) and gently scrub the tile grout. This will provide a nice and clean area between your tiles! Also, make sure to take a clean rag with water over where you just cleaned so that the chemicals are washed away and it's safe for skin and pet contact!
Normally you should be able to remove it with dry newspaper, it should come off quite easily once dry. Using a damp sponge will only spread it further.
