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.
â¢ Begin to clean up as soon as the grout begins to firm up and there is no longer a transfer of grout to your finger (usually between 10 to 30 minutes). â¢ Never allow the grout to remain on the tile surface for an extended length of time before completing the initial cleaning. â¢ Use as little water as possible when cleaning grout off the tile surface. Excess water will discolor the grout joints. â¢ When grouting a large area, grout and clean one section at a time rather than applying grout over the entire area.
