Waɗannan samfuran gypsum suna da jerin ayyuka daban-daban. Baya ga rawar da gypsum da sauran abubuwan da ke da alaƙa da shi, babban batun shine ƙarin abubuwan da ke ƙara cellulose ether suna taka muhimmiyar rawa. Tunda gypsum ɗin ya rabu zuwa gypsum mai ruwa da kuma hemihydrate gypsum, gypsum daban-daban yana da tasiri daban-daban akan aikin samfurin, don haka kauri, riƙe ruwa da jinkiri yana ƙayyade ingancin kayan gini na gypsum. Matsalar da aka saba fuskanta a waɗannan kayan ita ce rami da fashewa, kuma ba za a iya cimma ƙarfin farko ba. Don magance wannan matsalar, shine zaɓar nau'in cellulose da hanyar amfani da mahaɗin na retarder. A wannan batun, gabaɗaya ana zaɓar methyl ko hydroxypropyl methyl 30000. -60000cps, adadin ƙarin shine 1.5%–2%. Daga cikinsu, cellulose yana mai da hankali kan riƙe ruwa da kuma rage man shafawa. Duk da haka, ba zai yiwu a dogara da cellulose ether a matsayin retarder ba, kuma yana da mahimmanci a ƙara retarder citric acid don haɗawa da amfani ba tare da shafar ƙarfin farko ba.
