Gypsum plasters require smooth application, controlled setting time, and good adhesion to substrates. Chemical additives improve workability and reduce shrinkage cracking.
Retarders extend working time, allowing proper finishing. Cellulose ethers enhance water retention and improve trowelability. Polymer powders improve adhesion and flexibility.
Stabilizers ensure uniform mixing and prevent segregation. Defoamers improve surface quality by reducing air bubbles.
These additives ensure smooth finishing and improved durability.
