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.
The humidity, temperature and air flow in a room affect how long it takes to dry, but thinset generally is cured and ready to walk on or grout in 24 to 48 hours.Some installers and home specialists recommend waiting 72 hours for tiles applied to floors.ollow manufacturer directions for mixing to the proper consistency, because the thickness of the mortar at application determines how long it takes to cure. Avoid spreading too much thinset on the surface so that the tile does not slip and dry unevenly.
