In the experimental process, the applicant finds that the bonding strength between the coating layers containing the interface agent and the waterproof coating can be greatly improved by controlling the thickness of the interface agent layer, and particularly when the coating thickness of the interface agent layer is 1.2mm, the effect of resisting the external force of a wall body or a floor in the using process can be ensured, and the applicant speculates that the phenomenon is caused by the following reasons: when the coating thickness of the interfacial agent is 1.2mm, the interfacial agent can form a further complexing effect with the waterproof coating, so that the coating formed by the interfacial agent can be ensured to be smooth, the appropriate film forming temperature can be ensured, and the interfacial agent has extremely high interface matching degree when being cooperatively acted with JS waterproof latex and cement.
In addition, the applicant found that, in the system, if the thickness of the interface agent coating is thick, internal defects are easy to appear on the surface of the interface agent coated with the thick interface agent, local stress is easy to increase rapidly when external force is applied, and phenomena such as coating falling off and peeling occur.
In some preferred embodiments, the interfacial agent is prepared from the following raw materials in parts by weight: 50-150 parts of organic emulsion, 05-1.5 parts of preservative, 0.1-0.5 part of color paste and 300 parts of water 200-.

In addition, the applicant finds that if too much cement is added into the system, the powder agglomeration phenomenon can occur, the particles are in an unstable state due to van der waals force or coulomb force among cement particles in the JS waterproof emulsion, so that the agglomeration among the cement is caused, the distribution in the JS waterproof emulsion is further caused to be uneven, and the phenomena of poor anti-leakage effect, foaming and the like of a coating layer can occur in the using process.
