As an indispensable decorative material in decoration, putty powder is a base material for wall leveling and repairing, and it is a good foundation for other decorations. The wall surface can be kept smooth and uniform through the application of putty powder, so that future decoration projects can be carried out better. Putty powder is generally composed of base material, filler, water and additives. What are the main functions of redispersible latex powder as the main additive in putty powder:

① Effect on freshly mixed mortar;

A. Improve constructability;
B. Additional water retention to improve hydration;
C. Increase workability;
D. Avoid early cracking.

② Effect on hardened mortar:

A. Reduce the elastic modulus of mortar and increase the matching of the base layer;
B. Increase flexibility and resist cracking;
C. Improve powder shedding resistance;
D. Hydrophobic or reduce water absorption;
E. Increase the adhesion to the base layer.

Waterproof mortar refers to the cement mortar that has good waterproof and impermeability properties after being hardened by adjusting the mortar ratio and adopting a specific construction process. Waterproof mortar has good weather resistance, durability, impermeability, compactness, high adhesion and strong waterproof and anti-corrosion effect. What are the main functions of redispersible latex powder as the main additive in waterproof mortar:

① Effect on freshly mixed mortar:

A. Improve construction
B. Increase water retention and improve cement hydration;

② Effect on hardened mortar:

A. Reduce the elastic modulus of mortar and enhance the matching of the base layer;
B. Increase flexibility, resist cracking or have bridging ability;
C. Improve the density of mortar;
D. Hydrophobic;
E. Increase cohesion.
