How many degrees below zero can’t putty?

Best answer: below 0 degrees. When the construction temperature of putty is above 0℃, putty powder should be used within 4-5 hours after being mixed into paste, so as to avoid excessive deterioration. Blowing putty will freeze-dry at sub-zero temperature, and the putty will be powdered when the temperature rises, resulting in powder falling and delamination. Putty construction can be carried out in winter, and putty powder contains many chemicals. Blowing putty in winter can accelerate the volatilization of formaldehyde and reduce the residual time of these toxic gases indoors.

At the same time, the temperature is low in winter, so opening the window after the construction can make the putty on the wall dry faster, to a certain extent, avoid the putty pulverization and cracking, and the film forming effect will be better, but the temperature should not be too low.

Putty (mud filling) is a decorative material for leveling the wall surface, a thick paste paint, and an essential product before painting. Apply it to primer or directly to objects to remove uneven defects on the surface of the coated object. It is prepared with a small amount of binder, additives, a large amount of fillers and a proper amount of coloring pigments, which are mainly iron red, carbon black, chrome yellow, etc. The fillers are mainly calcium carbonate, talcum powder, etc. It can fill the local concave working surface, or scrape off the whole surface. Usually, it is applied to the surface of primer layer after the primer layer is dry. Good adhesion and no cracks during baking are required.
