Putty powder as an indispensable decoration material in decoration, which belongs to a kind of wall leveling, repair of the substrate, is a good foundation for the formation of other decoration. Through the painting of putty powder, the wall surface can maintain a good smoothness and have a uniform effect, so that the decoration project can be better carried out in the future.

Putty powder as an indispensable decoration material in decoration, which belongs to a kind of wall leveling, repair of the substrate, is a good foundation for the formation of other decoration. Through the painting of putty powder, the wall surface can maintain a good smoothness and have a uniform effect, so that the decoration project can be better carried out in the future. Putty powder is generally composed of base material, filler, water and additives, as the main additives redispersible latex powder in putty powder what is the main role:

 

① Effect on fresh mortar;

A, improve the construction;

B, additional water retention to improve hydration;

C, increase workability;

D, avoid early cracking.

 

The role of hardened mortar:

A, reduce the elastic modulus of mortar, increase the matching of the base;

B, increase flexibility, anti cracking;

C, improve the resistance to powder off;

D, hydrophobic or reduce water absorption;

E, increase the bonding force of the base.

 

Waterproof mortar refers to the cement mortar which has good waterproof and impermeability performance after hardening by adjusting the ratio of mortar and adopting specific construction technology. Waterproof mortar has good weather resistance, durability, impermeability, compactness and high adhesion, as well as strong waterproof and anti-corrosion effect. As the main additives redispersible latex powder in waterproof mortar what is the main role:

 

① Effect on fresh mortar:

A, improve the construction

B, additional water retention, improve cement hydration;

 

The role of hardened mortar:

A, reduce the elastic modulus of mortar, enhance the matching of the base;

B, increase flexibility, anti-cracking or have the ability to bridge;

C, improve the compactness of mortar;

D, hydrophobicity;

E, increase the bonding force.
