Sprinkling water on the surface of tiles after paving can play a role in tile maintenance, because the dry-mixed cement mortar under the tiles or the bonding material painted on the back of the tiles need a solidification and strengthening time when the tiles are just laid. Sprinkling water can also ensure that the moisture of the bonding material used on the ceramic tile will not evaporate too fast, which can well avoid the phenomenon of empty drum. If the tiles are sprinkled with water in time after paving, the moisture in the tile bonding material can be well guaranteed not to be evaporated, and the bonding strength can reach the due strength.
