Poyerekeza ndi miyambo konkire admixtures, youma wothira matope admixtures angagwiritsidwe ntchito mu mawonekedwe ufa, ndipo kachiwiri, iwo sungunuka m'madzi ozizira, kapena pang'onopang'ono kupasuka pansi zochita za alkali kusonyeza chifukwa chake.

Ntchito yaikulu ya redispersible latex ufa ndikupititsa patsogolo kusunga madzi ndi kukhazikika kwamatope. Ngakhale imatha kuletsa kusweka kwamatope (kuchepetsa kutsika kwamadzi) mpaka pamlingo wina, nthawi zambiri sagwiritsidwa ntchito ngati njira yolimbikitsira kulimba kwamatope, kukana ming'alu ndi kukana madzi.

Kuwonjezera ufa wa polima kumatha kupititsa patsogolo kusasunthika, kulimba, kukana ming'alu komanso kukana kwamatope ndi konkriti.
