7.Construction convenience.

Plaster construction with easy to wipe, easy to scrape flat, easy to repair, low labour intensity, less material consumption.

8.Sound insulation performance.

Plaster in the process of condensation, the internal production of tiny pores, so can attenuate the sound pressure, but also to prevent the transmission of sound energy, with good sound insulation performance.

9.Hygienic and healthiness.

Gypsum has the effect of disinfection and poisoning, in the room decorated with gypsum material, it is difficult for bacteria to survive and spread. Rooms with plaster are especially suitable for infants and elderly people.
