Description

technical field [0001] The invention relates to the field of putty materials, in particular to a leveling putty and a preparation method. Background technique [0002] In order to improve the living environment and comfort requirements, decoration in the current home improvement market is becoming more and more common and has a broad market prospect, but it has extremely strict requirements on the construction period of decoration, especially the leveling treatment of interior walls, requiring construction steps Simplify as much as possible, short maintenance period, will not take up valuable construction time, etc. Therefore, at present, the use of domestic building materials is mainly from new construction to renovation, with high construction requirements and short construction time, while the existing cement-based leveling putty is prone to hollowing, cracking, falling off and other problems, and the maintenance time is long. [0003] Gypsum itself is a kind of gelling ...

AI Technical Summary

Problems solved by technology

However, this lightweight bottom leveling putty still has the defects that the cement mortar wall surface is easy to hollow and crack, and the construction time is long

[0006] Therefore, it is an urgent problem in the industry to provide a wall plaster leveling putty that can replace the traditional wall cement plastering mortar, systematically solve the problems of cement mortar wall surface hollowing and cracking, and save time and labor.
