How soon after laying ceramic floor tile can you apply grout?

Under normal heat and humidity conditions you can grout tomorrow as long as you don t finish late tonight.

Any questions you can e mail me through my avatar and check my qualifications there. GL

Applying Grout

They missed a step....Use a good clear silicone caulking in the 'crack' where tile and grout meet wall. Otherwise, if for example, someone showers and gets water on the floor, it will get into this area, go under the tile and start to ruin the flooring under the tile. Mold and mildew can also grow in these wet areas. Molding trim only covers the edge of the tile giving it a neater more finished appearance, but it's still cosmetic...to protect, you need to seal or caulk around the outer edges of your flooring. You will also need to use a sealant on the grout between your new tiles as well, or the same problem can occur, as grout is porous and can absorb water and soapy liquids which then go down into the underflooring, and different liquids can stain the grout.

Hopefully,you have another bathroom.

You can grout the tile after 24 hours,however,you cannot walk on it at all during the 24 hour waiting time.

Have you removed the toilet? The tile needs to be applied under it.

Then,the toilet needs to be re-installed with a new wax sealing ring.

Good luck.

Usually you have to wait at least overnight. Just follow the directions on the packaging. The package that the thin set motar came in should tell you how long to wait before grouting.

Be sure to follow the manufacturer's specified drying time, usually 24 hours.

When applying grout it can be very stressful for the newly laid tile

You must make SURE it is dry before doing grout work.

Wait at least a day - it needs to completely support your weight and be fully cured before grouting.

At least a few days, and longer if it's humid. The glue under the tiles has to be completely dry before doing the grouting.

12-24 hours once the tile has fully cured

At least 24 hours recommended.
