I-polyurethane engangeni manzi kanye ne-acrylic engangeni manzi yizingubo ezimbili ezivamile ezingangeni manzi. Zinomehluko omkhulu ekubunjweni kwezinto ezibonakalayo, izici zokwakha kanye nezinkambu ezisebenzayo.
Okokuqala, mayelana nokubunjwa kwezinto ezibonakalayo, izintambo ze-polyurethane ezingenamanzi zivame ukwakhiwa nge-polyurethane resin, i-solvents nezithasiselo, futhi zibe nokunwebeka okuphezulu nokumelana nesimo sezulu. I-Acrylic waterproof coating yenziwe nge-acrylic resin, fillers and additives. Ibonakala ngokumisa ngokushesha nokusebenza okuhle kokwenza ifilimu.
Okwesibili, ngokwezici zokwakha, ukumbozwa kwe-polyurethane okungangeni manzi ngokuvamile kudinga izinga eliphezulu lobuchwepheshe ngesikhathi sokwakhiwa, kudinga ukwakhiwa endaweni ekahle kakhulu, futhi kube nezidingo eziphakeme zokwelashwa kwesisekelo. I-Acrylic waterproof coating ilula ukwakha futhi ingakhiwa ngaphansi kwezimo ezijwayelekile, futhi inezidingo eziphansi kakhulu endaweni ephansi.
Ngaphezu kwalokho, mayelana nezinkambu ezisebenzayo, ngoba i-polyurethane i-coating engangeni manzi ine-elasticity ephezulu kanye nokumelana nesimo sezulu, ifaneleka ezindaweni ezidinga ukuvikelwa isikhathi eside futhi ingaphansi kokucindezeleka okukhulu, njengophahla, izindlu zangasese, njll. I-Acrylic waterproof coating ifaneleka ukuvimbela amanzi okuvamile futhi ingakhiwa ngokushesha. Ilungele izikhathi ezithile lapho isikhathi sokwakha sisifushane futhi kudingeka ukufakwa ngokushesha.
Kunomehluko osobala phakathi kwezingubo ezingangeni manzi ze-polyurethane kanye nezingubo ze-acrylic ezingangeni manzi ngokwezinto ezibonakalayo, izici zokwakha kanye nezinkambu ezisebenzayo. Ngaphambi kokwakhiwa, ukugqoka okufanelekile okungangeni kwamanzi kudingeka kukhethwe ngokuvumelana nezidingo ezithile zephrojekthi.
