Description

technical field [0001] The invention relates to the technical field of building materials, and specifically discloses an interior wall putty paste and a preparation method thereof. Background technique [0002] Putty paste is a kind of decorative coagulation material for leveling the surface of the wall. It is a paste paint and an indispensable product before the paint is painted. Applied on the primer or directly on the object to remove uneven defects on the surface of the object to be coated. It is formulated with a small amount of paint base, a large amount of filler and an appropriate amount of coloring pigments. The pigments used are mainly iron red, carbon black, chrome yellow, etc. Fillers are mainly heavy calcium carbonate, talcum powder and so on. It can fill the partially sunken working surface, or scrape off the entire surface. It is usually applied to the surface of the primer layer after the primer layer is completely dry. It is required to have good adhesion...
