The interface agent can fill the pore walls of the substrate, reduce wall absorption, ensure better conditions in the cladding mortar bonding cementing. At the same time, the interface agent is responsible for the adhesion of the wall and the surface material, so as to ensure the whole integration into a permanent cohesive whole.

2，界面剂在可以对松散界面做套胶处理，使松散界面更坚实。

2, interface agent in rubber processing can do on the loose interface, the interface is more solid and loose.

3，界面剂可以和水泥混合使用对光滑表层做拉毛处理，增加光滑表面的粘结力。

3, the interface agent can be mixed and used to make cement galling treatment on smooth surface, increase the bond strength of smooth surface.

4，好的界面剂有更好的耐水效果，使墙体保持干燥，阻断了找平层水泥砂浆中的水份不被混凝土、加气混凝土很快吸收，从而保证水泥砂浆的硬化时间和强度。

4, the good interface agent has better water resistance effect, keeps the wall dry, and blocks the moisture content of cement mortar in the leveling layer, which is not absorbed quickly by concrete and aerated concrete, so as to ensure the hardening time and strength of cement mortar.
