Neutral putty:

De powdering: insufficient cementitious material, insufficient water retention of cellulose, low calcium content of heavy calcium
Construction performance: improved by bentonite and starch ether
Empty drum; Insufficient adhesion to the wall caused by
Layering: interface processing
Strength: can also be adjusted through calcium powder grading

Gray calcium based putty:

The problems include hollowing, powder peeling and yellowing, poor workability, powder peeling, delamination, cracking, and post thickening
De powdering: Insufficient cementitious material, insufficient water retention or addition of cellulose, impure ash and calcium
Poor construction performance: improved by bentonite and starch ether
Empty drum; Insufficient adhesion to the wall causes appropriate addition of latex powder
Layering: interface processing
Yellowing: Improper selection of cellulose
Cracking: Base cracking or excessive strength, hard cracking, coating too thick
Post thickening: Due to different water absorption rates of heavy calcium, it is recommended to use heavy calcium powder with zero or extremely low water absorption; Gray calcium contains undigested GaO.

Cement based putty:

The problems include hollowing, poor workability, powdering, delamination, cracking, insufficient water resistance, and false setting
De powdering: Insufficient cementitious material, insufficient water retention of cellulose, or insufficient addition amount
Poor construction performance: improved by bentonite and starch ether
Empty drum; Insufficient adhesion to the wall caused by reasonable addition of latex powder
Layering: interface processing
Yellowing: Improper selection of cellulose
Insufficient water resistance: insufficient latex powder and insufficient cementitious materials
Cracking: Base cracking or excessive strength, hard cracking, thick coating, filling holes with putty
False coagulation: Sodium gluconate can be added to extend the operable time
