Izithasiselo ezisetshenziswa ku-self-leveling gypsum mortar zingahluka, kodwa ngokuvamile zihlanganisa:

1. Ama-Superplasticizers: Lezi izithasiselo zamakhemikhali ezisetshenziselwa ukwandisa ukugeleza nokusebenza kodaka, okuvumela ukuba uzilinganise futhi ugcwalise izindawo eziphansi.
2. Ama-Retarders: Lezi izithasiselo ezinciphisa isikhathi sokumisa udaka, okuwunikeza isikhathi esengeziwe sokugeleza nezinga ngaphambi kokuba uqine.
3. I-Fiber Reinforcement: Ezinye izinsimbi ze-gypsum ezizilinganisa zingase futhi ziqukathe i-fiber reinforcement, engathuthukisa amandla nokuqina kodaka.
4. Ezinye Izithasiselo: Ezinye izithasiselo zingase zengezwe ukuze kuthuthukiswe ukumelana kwamanzi nodaka, ukuncipha, noma ukunamathela ku-subfloor.
