Plastering gypsum has become an increasingly popular material in modern construction due to its excellent performance and environmental benefits, gradually replacing traditional cement mortar. It is primarily made from semi-hydrated gypsum and type II anhydrous calcium sulfate, offering strong water retention, adhesion, and workability. With fast drying times, low shrinkage, and superior thermal insulation and humidity-regulating properties, plastering gypsum enhances indoor comfort and energy efficiency while reducing the risk of cracking and hollowing.

Globally, the use of plastering gypsum is well established. In Germany, over 75% of interior plasters are based on gypsum, and in Spain, that figure reaches up to 90%. In China, the market has grown rapidly since the promotion of machine spraying in 2014, with usage reaching 4.4 million tons in 2019 and expected to exceed 6 million tons by 2022. Driven by green building policies and the development of prefabricated construction, plastering gypsum is poised for even broader adoption.

In terms of application, plastering gypsum can be applied manually or via mechanical spraying. The latter method offers significantly higher efficiency—up to five times faster than manual labor—with a more consistent finish and improved bonding strength. Suitable for various substrates such as concrete, aerated blocks, and porous walls, plastering gypsum effectively reduces quality issues like hollowing and cracking, supporting cleaner, more efficient, and sustainable construction practices.
