What are the respective functions of gypsum powder and putty powder?

Generally used for foundation treatment, such as filling gaps, straightening the angle of yin and yang, and using putty to find equality for the first time on the wall surface of rough houses. When used as putty for wall leveling, gypsum powder is not directly used, and talcum powder will be added, otherwise the construction will be inconvenient.

The function of putty powder:

Usually putty is gypsum or cement-based, so rough surfaces are easier to bond firmly. However, during construction, a layer of interface agent should be painted on the base to close the base and improve the adhesion of the wall, so that putty can better bond with the base.

"putty powder" has both finished products and homemade on the spot. They are all used for leveling in a large area, and the thickness at a time should not be too large. The strength of putty layer is not as fast as gypsum powder, and the hardness is generally not as high as gypsum powder. Solids are generally used for surfaces.
