IiPlastiki: Ukuphucula ukuguquguquka kunye nokuqhubekeka kwemveliso yokugqibela.
I-Disperpersants: Iipowder zokunceda zisasazeke emanzini kwaye ziququzelele ukuhlanganiswa kwazo kwiifomyula.
4. Ukusebenza kunye nokusebenza:
I-latex powder enokuphinda isetyenziswe inika iipropathi ezininzi eziphambili kwizinto zokwakha, kubandakanya:
Ukubambelela: Ukwandisa amandla ebhondi, ngakumbi kwi-mortar kunye ne-adhesives tile.
Ukuguquguquka: Ukuphucula ukuchasana nokuqhekeka kunye nokuguqulwa, okubaluleke kakhulu kwiimbrane zokukhusela amanzi kunye ne-caulk.
Ukumelana naManzi: Ukubonelela ngokhuseleko kumswakama kunye nokuphucula ukuqina kwiindawo ezimanzi.
Ukuqhubekeka: Ukuphucula ukuphatha kunye neempawu zokusetyenziswa komxube owomileyo wokuxutywa.
5. Isicelo:
I-latex powder ephinda isetyenziswe isetyenziswa ngokubanzi kumashishini ahlukeneyo:
a. melana:
I-Tile Adhesives kunye neGrouts: Ukuphucula ukubambelela kunye nokuguquguquka ekufakeni i-tile.
I-Insulation yangaphandle kunye ne-Finishing Systems (EIFS): Ukuphucula ukusebenza kwe-EIFS ngokubonelela ukuguquguquka kunye nokumelana nokuqhekeka.
