Ke phofo e thehiloeng ho polymer eo, ha e kopantsoe le metsi, e ajoang hape ho etsa filimi. Filimi ena e fana ka litšobotsi tse 'maloa tsa bohlokoa ho seretse, tse kang ho khomarela ho ntlafetseng, ho tenyetseha, ho hanyetsa metsi le ho hanyetsa mapetso. Ha litlhoko tsa kaho li ntse li fetoha, li-RDP li se li sebelisoa haholo lihlahisoa tse khethehileng tsa seretse se omileng, moo melemo ea tsona e bapalang karolo ea bohlokoa ho ntlafatseng litšobotsi tsa ts'ebetso.
1.Phofo ea Polymer e ka Nchafatsoang (RDP) Kakaretso
Phofo ea Polymer e Nchafalitsoeng (RDP) e hlahisoa ka ho omisa li-emulsion tsa li-polymer tsa maiketsetso, hangata styrene-butadiene (SB), vinyl acetate-ethylene (VAE), kapa li-acrylic. Li-polymer tsena li siloa hantle 'me li na le bokhoni ba ho qhalana hape ha li kopantsoe le metsi, ho etsa filimi e ntlafatsang thepa ea mechini ea seretse.
Litšobotsi tsa bohlokoa tsa RDPs:
Ntlafatso ea ho khomarela: E ntlafatsa ho kopana le li-substrate.
Ho tenyetseha: E fana ka sebaka sa ho sisinyeha le ho fokotsa ho petsoha.
Khanyetso ea metsi: E eketsa ho hanyetsa ho kenella ha metsi.
Ho sebetsa hantle ho ntlafetseng: E ntlafatsa bonolo ba ho e sebelisa.
Ho tšoarella ho matlafetseng: E thusa ho sebetsa nako e telele maemong a feteletseng.
2.Likopo Lihlahisoa tse Ikhethang tsa Seretse se Omileng
a.Likhomaretsi tsa Lithaele
Likhomaretsi tsa thaele ke e 'ngoe ea lits'ebetso tse tloaelehileng tsa Redispersible Polymer Powder (RDP).

c.Li-mortar tsa ho lokisa
Li-mortar tsa tokiso li sebelisoa ho lokisa libaka tse senyehileng, tse kang konkreite e petsohileng kapa e qhalaneng. Litšebelisong tsena, RDP e bapala karolo ea bohlokoa ho ntlafatseng tse latelang:
Ho hokahana le libaka tsa khale: Phofo ea Polymer e Nchafalitsoeng (RDP) e ntlafatsa ho khomarela li-substrate tse seng li ntse li le teng, e leng se etsang hore thepa ea tokiso e khomarele ka mokhoa o sireletsehileng.
Bokhoni ba ho sebetsa: RDP e etsa hore seretse se be bonolo ho se sebelisa le ho se lekanya, e leng se ntlafatsang boiketlo ba tšebeliso ka kakaretso.
Ho tšoarella: Ka ho ntlafatsa thepa ea lik'hemik'hale le ea mechine ea seretse, RDP e netefatsa litokiso tse tšoarellang nako e telele tse hanelang ho petsoha, ho fokotseha le tšenyo ea metsi.
| Thepa | Ntle le RDP | Ka RDP |
| Ho kopana le substrate | E itekanetseng | E babatsehang |

3.Melemo eaPhofo ea Polymer e ka Nchafatsoang (RDP)Lihlahisoa tsa Dry Seretse
Phofo ea Polymer e qhalakantsoeng hape (RDP) e ntlafatsa haholo ts'ebetso ea lihlahisoa tsa seretse se omileng, e fana ka melemo e latelang:
a.Khomarelo e Ntlafalitsoeng
RDP e ntlafatsa matla a ho kopanya pakeng tsa seretse le di-substrate tse fapaneng, e leng sa bohlokwa haholo bakeng sa ditshebediso tse kang dikhomaretsi tsa thaele le di-mortar tsa tokiso, moo ho hlokahalang ho kgomarela ho matla ho thibela ho arohana kapa ho hloleha ha nako e ntse e ya.
b.Khanyetso ea Mapetso
Ho tenyetseha ho fanoang ke RDPs ho dumella ditsamaiso tsa seretse ho ikamahanya le metsamao ya mocheso, ho fokotsa kotsi ya mapetso. Thepa ena e bohlokwa bakeng sa ditshebediso tsa kantle, tse kang diplaster le ETICS, moo metsamao ya meaho kapa maemo a lehodimo a feteletseng a ka bakang mapetso.
c.Khanyetso ea Metsi
Bakeng sa lits'ebetso tsa kahare le kantle, RDPs e kenya letsoho ho haneleng metsi hamolemo, e thusa ho thibela ho kenella ha mongobo. Sena se molemo haholo libakeng tse mongobo, se netefatsa hore thepa ea kaho e tšoarella nako e telele le ho tšoarella.
d.Ho ntlafala ha ho sebetsa
Di-mortar tse nang le RDP di bonolo ho di sebedisa, ho di hasanya le ho di lokisa, e leng se ntlafatsang boiphihlelo ba mosebedisi ka kakaretso. Ena ke molemo o moholo ho dikhomaretsi tsa dithaele le di-mortar tsa ho lokisa, moo bonolo ba ho di sebedisa bo ka potlakisang tshebetso ya kaho.
e.Ho tšoarella
Li-mortar tse nang le Powder ea Redispersible Polymer (RDP) li hanela ho tsofala le ho taboha habonolo, li netefatsa ts'ebetso e tšoarellang nako e telele tlas'a likhatello tse fapaneng tsa tikoloho.
Phofo ea Polymer e ka Nchafatsoang (RDP)ke dikarolo tsa bohlokwa tlhahisong ya di-mortar tse ikgethang tse ommeng, tse ntlafatsang thepa ya tsona ya mmele jwalo ka ho kgomarela, ho tenyetseha, ho sebetsa hantle le ho tshwarella. Ebang di sebediswa ho dikhomaretsi tsa thaele, di-plaster, di-mortar tsa tokiso, kapa ditsamaiso tsa ho kenya mocheso ka ntle, di-RDP di ntlafatsa haholo tshebetso le bolelele ba sehlahiswa. Ha maemo a kaho a ntse a tswela pele ho hloka thepa e ikgethang haholoanyane, tshebediso ya di-RDP ho di-mortar tse ommeng e tla tswela pele ho bapala karolo ya bohlokwa ho fihlelleng ditlhoko tsena.
