HY type concrete interface treatment agent

First-class performance
This
concrete interface agent is a gray powder composite material formulated from cement-based inorganic binder, fine aggregate, organic additives, etc. The treated concrete surface can enhance the adhesion of the cement mortar to the base layer, and has high water resistance, heat resistance, and freeze-thaw resistance, thereby avoiding the hollowing, shelling, and falling off of the ash layer. It has a significant effect on improving the construction quality of decoration and renovation projects.

Three-use instructions
Dust, oil, etc. on the surface of the concrete should be removed before construction to avoid affecting the bonding strength.
During seasonal construction or when the wall surface is relatively dry, the wall surface should be moistened with water before construction.
Use water to make the interface agent into a thick paste. The water-cement ratio is about
. Stir thoroughly and leave it for

minutes. Stir slightly after the interface agent thickens, that is be usable.
After mixing the interface agent, apply it on the concrete base layer with a mud board. The thickness is about

mm
(not less than
mm
) Close After the slurry
(generally
minutes
depends on the environmental conditions
), the cement mortar leveling layer can be applied. If the thickness of the leveling layer is greater than
mm, it needs to be applied in layers, and the dosage per square meter is about
kg.
Be careful not to carry out outdoor construction when it rains.
The operating temperature should be above
℃.
