High strength, excellent water, alkali and freeze-thaw resistance. High adhesion to surface of various walls and exterior coatings.

It has good waterproof property, high crack resistance because imported hydrophobic polymer is incorporated in the formulation.

The disadvantage of using traditional primer. Such as random selection of materials and mixing ratio, low strength and poor water, alkali resistance, can be overcome. Moreover, workload and labor are saved, application is easier.
