Uma kukhulunywa ngezinto zokuvala, kunezinhlobo ezintathu eziyinhloko zama-sealant ezivame ukusetshenziswa ezinhlotsheni ezahlukene:i-polyurethane, i-silicone, futhii-latex esekwe emanzini. Ngayinye yalezi zivalo zokuvala inezakhiwo ezihlukile futhi ifanele ukusetshenziswa okuhlukile. Ukuqonda izakhiwo zalezi zivalo zokuvala kubalulekile ekukhetheni isivalo sokuvala esifanele sephrojekthi ethile.
Izinto zokuvala ze-polyurethanezaziwa ngokuqina kwazo okumangalisayo kanye nokuguquguquka kwazo. Zivame ukusetshenziswa ezakhiweni nasezimbonini lapho kudingeka khona uphawu oluqinile noluhlala isikhathi eside. Izivalo ze-polyurethane azikwazi ukumelana nesimo sezulu, amakhemikhali, kanye nokuguguleka, okwenza zibe zilungele ukusetshenziswa ngaphandle. Ziyakwazi futhi ukunamathela ezintweni ezahlukahlukene, okuhlanganisa ukhonkolo, ukhuni, insimbi kanye nepulasitiki. Ngaphezu kwalokho, izivalo ze-polyurethane zinokumelana okuhle kakhulu nemisebe ye-UV futhi zifanelekela ukuvala amalunga nezikhala ezakhiweni zangaphandle.
Izinto zokuvala ze-siliconezithandwa ngokunamathela kwazo okuhle kakhulu kanye nokuguquguquka kwazo. Zivame ukusetshenziswa ekusetshenzisweni kwamapayipi, ezimotweni kanye nasezintweni zikagesi ngenxa yokumelana kwazo nomswakama kanye namazinga okushisa aphezulu. Izinto zokuvala i-silicone zaziwa nangokukwazi kwazo ukuhlala ziguquguquka ebangeni elikhulu lokushisa, okwenza zifaneleke kokubili ukusetshenziswa ngaphakathi nangaphandle. Ziphinde zimelane nokukhula kwesikhunta kanye nesikhunta, okwenza zibe zilungele ukuvala amalunga ezindaweni ezinomswakama njengezindlu zangasese namakhishi. Ngaphezu kwalokho, izinto zokuvala i-silicone zinezakhiwo ezinhle zokuvala ugesi, okwenza zifaneleke ukuvala izingxenye zikagesi kanye nokuxhumeka.
Izinto zokuvala i-latex ezisekelwe emanzinizaziwa ngokulula kwazo kokusetshenziswa kanye nokupendwa kwazo kalula. Zivame ukusetshenziswa ezisetshenziswa ngaphakathi njengokuvala izikhala kanye nemifantu ezindongeni, emafasiteleni naseminyango. Izivalo ze-latex ezisekelwe emanzini kulula ukuzihlanza ngamanzi futhi zinephunga eliphansi, okwenza zifaneleke ukusetshenziswa ngaphakathi. Zingapendwa futhi ukuze zihlanganiswe kahle nezindawo ezizungezile. Nakuba izivalo ze-latex ezisekelwe emanzini zingase zingabi ziqinile njengezivali ze-polyurethane noma ze-silicone, ziyisinqumo esihle kakhulu samaphrojekthi okuvala ngaphakathi lapho kulula ukusetshenziswa kanye nobuhle kubalulekile.
Ngamafuphi, ama-polyurethane, i-silicone, kanye nama-latex sealants asekelwe emanzini ngalinye linezakhiwo ezihlukile futhi lifanele ukusetshenziswa okuhlukile. Ama-polyurethane sealants aziwa ngokuqina kwawo kanye nokumelana nesimo sezulu, okwenza abe afanele ukusetshenziswa ngaphandle. Ama-silicone sealants ayaziswa ngokuguquguquka kwawo kanye nokumelana nomswakama kanye namazinga okushisa aphezulu, okwenza afaneleke ukusetshenziswa okuhlukahlukene. Ama-latex sealants asekelwe emanzini kulula ukuwafaka, ayapendwa futhi anephunga eliphansi, okwenza abe afaneleke kumaphrojekthi okuvala ngaphakathi. Ukuqonda izakhiwo zala ma-sealants kubalulekile ekukhetheni i-sealant efanele yephrojekthi ethile.
