Lightweight gypsum mortar is a new type of wall plastering material. It is made of semi-hydrated gypsum as the basic material, high molecular polymer as the cementing material, and dry-mixed with inorganic fillers. It changes the traditional habit of cement base as a cementitious material, and has good compatibility and adhesion with various foundation walls. It is a new type of interior wall paint.
Lightweight gypsum mortar has high bonding strength with the substrate and is not prone to dents and cracks. The advantages of gypsum are fast solidification and hardening, small hydration expansion, stable volume after hardening, and no shrinkage or cracking. The thermal conductivity of lightweight gypsum mortar is similar to that of air-entrained concrete, which helps avoid hollowing or cracking due to large differences in thermal expansion and contraction deformations.
Plastering lightweight gypsum mortar is a new, more environmentally friendly and more economical product that can replace the cement mortar promoted in the country. It not only has the strength of cement, but also has the advantages of health, environmental protection, durability, strong adhesion, not easy to grind, not cracked, not hollowed out, not pulverized, etc. It is easy to use and saves costs.

It changes the traditional habits of cement-based cementitious materials and has good compatibility and adhesion with various base layer walls.
Lightweight gypsum mortar used for mechanical spraying construction should not only meet the technical requirements of relevant standards and specifications, but also have pumping and spraying properties, that is, it must have Good rheology, processability, wet adhesion, suitable particle grade, setting time, etc. . From the surface of the mortar, the particle distribution of the material is irregular, like a cavity with many holes. But during the construction process, the texture of the material is actually very smooth, the wall has good sealing properties, the material is lightweight, has good thermal insulation, and is resistant to high temperatures and wear. </p
