How to choose putty powder with good quality? According to the workers who have many years of working experience, we should consider putty hardness, whiteness, fineness, workability, construction performance and environmental protection. It is difficult to distinguish putty from good putty by naked eyes. On the contrary, the quality of dispersed and pinhole putty is poor, and the stickiness of putty produced by grey knife and good putty falls down quickly is small. After construction, it is good putty that the hand mould does not drop white, the nails do not scratch, and the water brush does not drop after putty is dried.
