It s only a small job and will only take you 20 30 minutes to grout it so for what its worth i would suggest waiting 24 hours for it to fully dry.
Grout tile how long after attach to wall.
Once the grout has started to harden 20 to 30 minutes begin sponging photo 7.
My advice would be leave it overnight as you will have to remove the spacers to actually grout and depending on how tight you have wedged the tiles to the spacers you may end up pulling off the tiles.
Don t be fooled by.
Grout it clean up and enjoy.
Generally 24 hours will do for this and some setup more quickly.
Don t use just any sponge especially one from the kitchen.
Grouting is the final step of installing ceramic wall tile after the tile adhesive has fully cured.
Apply mortar when the ambient air temperature is between 50 and 100 degrees fahrenheit.
Grouting is not difficult to do well but it is even easier to do poorly.
24 to 48 hours you should wait at least 24 hours before grouting the tiles.
Rinse your sponge often and repeat until you re left with a thin haze.
Choose a hydrophilic water loving sponge.
Mortar must set at least 24 to 48 hours before grouting.
Sweep a damp not wet sponge diagonally across the tile.
Time before grouting drying time varies depending on room temperature humidity and how much moisture there is in the mortar when it s applied.
