Features of double fly powder and putty powder:
Double fly powder is called white powder in many areas of the north, referred to as: white, and the putty is also called shaving white. There is no need to fly powder here, and it is replaced by talcum powder.

Putty powder, in fact, includes the above two, the two are putty powder, but now there is finished putty powder sold, but the ingredients inside, not just double fly powder, or talcum powder, it The bag contains the binder component. As long as the appropriate water is added, it can be used as a wall putty after mixing. If it is a finished putty powder, it is different from the double fly powder and talcum powder.
Double fly powder or talcum powder is prepared by artificial on-site additives. This additive generally consists of building glue (such as 801, etc.), cellulose, and cooked rubber powder. Our practice is to add an appropriate amount of white latex on the basis of the above additives to increase the adhesion and hardness of the putty layer; and the putty of the finished putty powder directly added with water, the putty layer is relatively tender, and the painter polishes it. It's easier, but the quality is not ideal. Therefore, when using, we will also add an appropriate amount of white latex while stirring and then approving the wall.
