Grout tile how long after attach to wall.
Grout it clean up and enjoy.
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.
Apply mortar when the ambient air temperature is between 50 and 100 degrees fahrenheit.
Choose a hydrophilic water loving sponge.
Generally 24 hours will do for this and some setup more quickly.
Don t use just any sponge especially one from the kitchen.
Sweep a damp not wet sponge diagonally across the tile.
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.
Follow the package instructions for the tile mastic or thinset used for adhering the tiles to the wall.
Time before grouting drying time varies depending on room temperature humidity and how much moisture there is in the mortar when it s applied.
Mortar must set at least 24 to 48 hours before grouting.
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.
You may notice that the edges of the thinset or the thinset showing through the grout lines looks dry.
Rinse your sponge often and repeat until you re left with a thin haze.
