Don cimma sakamako mafi kyau, ana ba da shawarar yin amfani da shi tare da sauran abubuwan da suka dace kamar redispersible latex foda, mai rage ruwa, fiber anti-cracking, da dai sauransu, da kuma inganta ƙirar ƙira bisa ga tsarin gini da bukatun.
Aikace-aikace naHPMCa cikin gyaran turmi ya zama hanya mai mahimmanci don inganta aikin samfur. Kyakkyawan riƙewar ruwa, kauri, aikin aiki da mannewa ba kawai inganta tasirin amfani da turmi mai gyara ba, amma kuma yana ba da tallafin fasaha don gyaran gyare-gyare a cikin mahalli masu rikitarwa. Yayin da masana'antar gine-gine ke ci gaba da haɓaka buƙatunta don aiwatar da kayan gyara, ƙimar aikace-aikacen HPMC za ta zama mafi shahara, kuma zai zama muhimmin maɓalli mai mahimmanci a cikin tsarin turmi mai girma na gaba.
