Gypsum Plasters

Gypsum based plaster is normally referred to as pre-mixed dry mortar which mainly contains gypsum as a binder.

Gypsum plaster is mixed with water at job-site and is used for the finishes on various interior walls - brick, concrete, ALC block etc.

There are three main application methods: Gypsum Finishing Plaster , Gypsum Hand Plaster (GHP) and Gypsum Machine Plaster (GMP). cellulose ether is an essential additive for optimal performance in each application of gypsum plast

● Gypsum Machine Plaster

Gypsum Machine Plaster is used when working on large walls.

The thickness of the layer is normally 1 to 2cm.  By using plastering machines, GMP helps to save working time and cost. 

GMP is popular primarily in Western Europe. Recently, using lightweight mortar for gypsum machine plaster is becoming increasingly popular due to its provision of convenient working condition and thermal insulation effect.

cellulose ether is essential in this application as it provides unique properties such as pumpability, workability, sag resistance, water retention etc.

● Gypsum Hand Plaster

Gypsum Hand Plaster is used for work inside the building. 

It is a suitable application for small and delicate construction sites due to its extensive use of manpower. Thickness of this applied layer is normally 1 to 2cm, similar to GMP.

cellulose ether provides good workability while securing stronger adhesion power between plaster and wall.

● Gypsum Finishing Plaster

Gypsum Finishing Plaster, or Gypsum Thin Layer Plaster, is used to provide good leveling and smoother surface to the wall.

The layer thickness is generally 2 to 5 mm. 

In this application, cellulose ether plays a vital role in improving workability, adhesion strength and water retention.

Gypsum Filler/Joint Filler

Gypsum Filler or Joint Filler is a dry mixed mortar that is used to fill the joints between wall boards.

Gypsum filler consists of hemihydrate gypsum as a binder, some fillers and additives.

In this application, cellulose ether provides strong tape adhesion power, easy workability, and high water retention etc.

Gypsum Adhesive

Gypsum adhesive is used to attach gypsum plasterboard and cornice to masonry wall vertically. Gypsum adhesive is also used in laying gypsum blocks or panel and filling gaps between blocks.

Because fine hemihydrate gypsum is the main raw material, gypsum adhesive forms durable and powerful joints with strong adhesion.

The primary function of cellulose ether in gypsum adhesive is to prevent material separation and to improve adhesion and bonding. Also cellulose ether helps in terms of anti-lumping..

Anxin cellulose ether products HPMC/MHEC can improve by the following properties in tile grout :

·Provide suitable consistency, excellent workability, and good plasticity

·Ensure the proper open time of the mortar

·Improve the cohesion of the mortar and its adhesion to the base material

·Improve sag-resistance and water retention
