4. Rage modules na roba na turmi, inganta iyawar nakasa da rage fashewar sabon abu.
5. Inganta juriyar lalacewa na turmi.Haɓaka juriya na lalacewa ya samo asali ne saboda kasancewar wani adadin manne a saman turmi.Foda mai manne yana aiki azaman haɗin gwiwa, kuma tsarin omentum da aka kafa ta hanyar manne foda zai iya wucewa ta cikin ramuka da fasa a cikin turmi siminti.Yana haɓaka haɗin kai tsakanin kayan tushe da samfuran hydration na siminti, don haka ƙara juriya ga lalacewa.
6. Ba da turmi kyakkyawan juriya na alkali.
Na uku: Matsayin foda na latex wanda za'a iya rarrabawa a cikin tile adhesives shine galibin abubuwan da ke biyo baya
