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.
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?
