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.
Thinset Dry Time. I recently installed a tile floor (12x24 full body porcelain) in my bathroom using Ditra XL and was wondering how long should I let the floor dry before walking on it.he Schluter website says the unmodified thinset drys within 24 hours, but I cannot find a dry time for the modified thinset used to adhere the Ditra to the plywood subfloor.
