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. Don't be fooled by this. The thinset under the tiles isn't receiving as much air as the edges and is therefor not fully cured.
This Site Might Help You. RE: How long do you wait to grout after laying tile? 18 x 18 w/flexbond? My husband set the new tiles in the kitchen (18x 18 ceramic tiles, flexbond thinset) and he finished up around midnight. How long do we wait to grout it? How long before we can walk on it? How long after grouting can we move the appliances back in?
