Ho feto-fetoha ha maemo ho fanoang ke li-RDP ho lumella litsamaiso tsa seretse ho ikamahanya le metsamao ea mocheso, ho fokotsa kotsi ea mapetsong. Thepa ena e bohlokoa bakeng sa lits'ebetso tsa kantle, joalo ka plasters le ETICS, moo metsamao ea meaho kapa maemo a leholimo a feteletseng a ka bakang mapetsong.
c.Ho hanyetsa Metsi
Bakeng sa lisebelisoa tse ka hare le ka ntle, li-RDP li kenya letsoho ho thibela metsi hantle, ho thusa ho thibela ho kenella ha mongobo. Sena se molemo ka ho khetheha libakeng tse mongobo, ho netefatsa nako e telele le ho tšoarella ha thepa ea kaho.
d.Mokhoa o Ntlafetseng oa ho sebetsa
Li-mortar tse nang le RDP li bonolo ho li sebelisa, ho hasanya, le ho lokisa, ho ntlafatsa boiphihlelo ba basebelisi ka kakaretso. Ena ke molemo o moholo ho li-adhesive tsa lithaele le ho lokisa seretse, moo boiketlo ba tšebeliso bo ka potlakisang mosebetsi oa kaho.
e.Ho tšoarella
Li-Mortar tse nang le Redispersible Polymer Powder(RDP)s li khona ho khathala le ho taboha, li netefatsa ts'ebetso e tšoarellang halelele tlas'a likhatello tse fapaneng tsa tikoloho.
Redispersible Polymer Powder(RDP)s ke likarolo tsa bohlokoa ha ho etsoa lirekere tse khethehileng tse omeletseng, tse matlafatsang thepa ea tsona ea 'mele joalo ka ho khomarela, ho tenyetseha, ho sebetsa le ho tšoarella. Ho sa tsotellehe hore na li sebelisoa ka ho khomarela lithaele, li-plaster, lirafshoa tsa ho lokisa, kapa mekhoa ea ho kenya ka ntle, li-RDP li ntlafatsa haholo ts'ebetso le bophelo bo bolelele ba sehlahisoa. Ha maemo a kaho a ntse a tsoela pele ho batla thepa e khethehileng, tšebeliso ea li-RDP ka seretseng se ommeng e tla tsoela pele ho phetha karolo ea bohlokoa ho khotsofatsa litlhoko tsena.
