Ukuqina okuphezulu ngemva kokuhlangana, okungewona ubuthi, awanambitheki futhi kunobungani bemvelo

1. Okokuqala hlanganisa ukwakhiwa kwe-gypsum powder ne-retarder, i-Yuhe hydroxypropyl methylcellulose noma ezinye izithasiselo ngokulinganayo, bese ufaka isihlabathi, i-calcium esindayo, njll., engeza isihlabathi noma i-calcium enzima bese ugoqa imizuzu engu-15 ngaphambi kokukhulula.(Qaphela: Ngenxa yamandla adonsela phansi ahlukile wezinto ezisetshenziswayo, kuzoba ne-stratification ngemuva kokunyakaziswa kwesikhathi eside, okuzothinta ikhwalithi yomkhiqizo.)

2. Kweminye imikhiqizo, efana ne-mold gypsum namanzi ejeli anesikhathi eside, ungafaka i-retarder emanzini kuqala, bese uyengeza ukuze uyisebenzise ngemva kokuncibilika.
