In the construction process of paving and pasting the ceramic tiles, the ceramic tiles and the wall surfaces are mainly bonded by cement in the traditional method. However, the ceramic tiles directly paved with the cement are easy to hollowly and fall off, and the maintenance cost is high. At present, the tiling technology adopts the ceramic tile to glue more, and the ceramic tile is glued before the construction, and the wall needs moist and keeps better roughness, when there is floating dust, greasy dirt etc. to remain in the wall, can seriously influence the gluey bonding strength of ceramic tile. The tile glue stirred uniformly needs to be used up quickly, otherwise, the tile glue is easy to dry and knot and cannot be reused.
