The first and second passes used talcum powder and 90 1 glue. Can the finished mud be used for the third time? Please answer the question more specifically.

Not only 90 1 was added to talcum powder, but also cellulose, cooked rubber powder and a small amount of white latex were added. In this way, the putty layer will have a good hardness, and the cooked rubber powder has a mildew-proof effect. As long as the additives in talcum powder putty are properly matched, this putty can be used directly without using finished putty. Even if the finished putty is used, a small amount of white latex still needs to be added to the finished putty, because the additives in the finished putty are not enough, and the hardness of the putty layer is poor. Only by adding a small amount of white latex can it have good hardness-adhesion. Hope to adopt, thank you!
