Interface mortar, also known as interface agent, is made by mechanically mixing cement, quartz sand, polymer binder with various additives. Mainly used to handle the connection between the wall and the insulation layer, and to improve the surface bonding performance of the base or insulation layer. Also known as polymer interface mortar. Its main function is to improve the bonding performance between the base layer and the insulation layer surface, ensuring a strong bond between the two. Interface mortar can also seal the pores on the surface of building materials, reduce the absorption of walls, and thus improve the bonding effect.
Main technical performance indicators:
1. Sealing the pores of the substrate: Interface mortar can seal the pores of the substrate, reduce the absorption of the wall, thereby achieving the effect of slowing down and reducing the suction of moisture from the lightweight masonry in the covering mortar, ensuring that the covering mortar material is bonded and solidified under better conditions.
2. Improve the surface strength of the substrate: The interface mortar can solidify, improve the surface strength of the substrate, and ensure that the mortar has good bonding strength.
3. Bonding bridging effect: The interface mortar can bear the bonding bridging effect between the masonry and the plaster, ensuring that the upper wall mortar and the masonry surface are more easily combined into a solid whole.
4. Permanent bonding strength: The interface mortar has permanent bonding strength, does not age, hydrate, and does not form a membrane structure that affects durability bonding.
5. Simplify the construction process: The use of interface mortar can eliminate the secondary watering process before plastering, effectively avoiding wall shrinkage.
6. Protecting building structures: Interface mortar can resist the hazards of natural environments such as wind, rain, and snow on buildings, while greatly improving their durability.
7. Beautification and decoration effect: The application of interface mortar is not limited to protecting building structures, but also has a beautifying and decorative effect.

Application scenarios：

Enhance the adhesion between the external wall insulation layer and the base layer, and improve the adhesion between the base layer and the decorative layer.

Used to repair the damage on the surface of concrete, restore its original strength and appearance.
