(2) : improper flooding because of bad brick immersed brick too dry causing binding mortar water too fast, affect the bonding layer and in combination with the solid brick, also because of the brick after flooding is not dry, even left floating in the surface of tiles, when tile with adhesive layer, surface with you in the bottom of a tile excess water film formed between bonding layer sliding layer, will also affect the effect. 2, deal with surface too smooth at the grass-roots level, paste before the brick base is too dry, cause backwater fast at the grass-roots level, adhesive layer and grassroots due to lack of frictional resistance and bonding water, it is hard to together. Small make up remind: external thermal insulation wall surface uneven, vertical deviation or metope, lead to local plasterer too thick gray base surface caused by bonding mortar bond mortar, affect the combination of brick and grassroots grassroots plasterer too thin, not easy bonding compaction can also lead to the combination of surface peeling effect and grassroots 3, tile when temperature is too low because of the temperature problem, the material such as cement condensation effect will be affected, ceramic tile floor tile will appear fall off phenomenon, in general, try to avoid in winter construction, because the year after the spring thaw brick from major are prone to fall off. If the winter construction, floor tile, ceramic tile in the shop before to after bubble water treatment, you must see to it that the moisture content of saturated state. Only in this way, the adhesive is not caused by the water absorption and cement bonding is not strong. 4, improper construction technology (1) binding mortar quality is bad, when the construction of mortar mix proportion, mixing unevenness, insufficient strength, workability, secrete water is bad, will affect the tile adhesive strength with base. (2) the brick pressure untrue, operation technique is wrong, uneven force, lack of tile adhesive layer and bonding force between the grass-roots, individual brick after pasting again in order to rectify move, knead, knock will also make the combination has the serious destruction of bonding layer, so it can also influence the combination of brick and grassroots.
