Waterproof mortar refers to a rigid waterproof material that achieves waterproofing and impermeability by improving the compactness and crack resistance of mortar. Mainly used for waterproofing projects that will not cause harmful cracks due to structural settlement, temperature, humidity changes, and vibration. There are three types of waterproof mortar used as waterproof layers in waterproofing projects: (1) rigid multi-layer plastering cement mortar; (2) Waterproof mortar mixed with waterproofing agent; (3) Polymer cement waterproof mortar:

Today we will focus on understanding polymer cement waterproof mortar:
It refers to a mortar made by mixing cement and redispersible polymer powder as a binding cementitious materials with sand. After the polymer cement mortar hardens, the polymer in the mortar can effectively seal the connected pores, increase the compactness and crack resistance of the mortar, and thus improve the impermeability and impact resistance of the mortar. Polymer dispersion is a liquid material in which a certain amount of polymer latex powder and auxiliary additives (such as emulsifiers, stabilizers, defoamers, curing agents, etc.) are added to water and stirred to evenly disperse polymer particles in water. Common polymer varieties include: organosilicon, cationic neoprene latex, ethylene polyvinyl acetate copolymer lotion, styrene butadiene rubber latex, vinyl chloride vinylidene chloride copolymer lotion, etc.
