This stress will be tensile during temperature decrease, or compressive. during temperature increase. If the compressive stress level exceeds the column buckling resistance of. the restrained length, then lateral buckling (or snaking) will occur.
Dry Time. In most cases, you should allow the grout to dry overnight before using that room as total dry time may take up to 24 hours. If you are thinking about sealing your grout after you have installed it, you need to wait even longer than that so that all of the moisture has had time to be released.
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.llow thinset to dry for 24 to 48 hours. Thinset mortar adheres tiles to floors, countertops, backspashes and walls. It shouldn't be walked on or disturbed during the drying process, as doing so could cause a serious misalignment of the tiles you just laid, a problem that would be difficult to fix.
