Emkhakheni wokukhiqiza ngokunemba okukhulu, ukugaya nokupholisha amapuleti obuso be-granite kudlala indima ebalulekile ekunqumeni ukuthi ubuso buyisicaba kangakanani, bucwebezela kangakanani, kanye nokunemba okuphelele. Nakuba i-granite ingenye yezinto zemvelo eziqinile nezizinzile kakhulu, ukufeza ukunemba okudingekayo kwezinga le-micrometer kusancike ekukhetheni ngokucophelela kanye nokusetshenziswa okufanele koketshezi lokupholisha kanye nezinto zokupholisha.
Ngesikhathi senqubo yokugaya, lezi ziphuzo kanye nezinto ezisetshenziswayo azigcini nje ngokuthonya amazinga okususwa kwezinto kodwa futhi zithinta nokuphela kobuso kanye nokuqina kwesikhathi eside kwepulatifomu yegranite. Ngakho-ke ukukhetha uhlobo olufanele kanye nokwakheka kubalulekile ekufinyeleleni imiphumela emihle kanye nokwandisa isikhathi sokuphila kwengxenye yegranite enembile.
Ezisetshenzisweni zobungcweti, uketshezi kanye nezinto ezisetshenziswa ekugayeni ipulatifomu ye-granite ngokuvamile zihlukaniswe ngezigaba ezine ezisebenzayo: izinto zokuhlanza, izinto zokubhula, izinto zokupholisha, kanye nezinto zokuvala.
Izihlanzi zisetshenziswa kakhulu ukususa ukungcola kanye nezinsalela ebusweni be-granite—njengowoyela, i-oxide, noma uthuli olucolekile—ngaphambi nangemva kokugaya. Izixazululo zokuhlanza ezivamile zifaka phakathi izihlanzi ze-pH ezingathathi hlangothi, ama-ejenti ane-acid encane, noma izihlanzi ze-alkaline. Uma usebenzisa izihlanzi zamakhemikhali, opharetha kumele balawule ukuhlushwa kanye nesikhathi sokuchayeka ukuze bavimbele ukugqwala noma ukufiphala kwamakhemikhali ebusweni be-granite.
Ama-abrasives asebenza njengendawo ebalulekile yokususa izinto. Ama-grains abrasive asika futhi alinganise ubuso be-granite ukuze kususwe amaphutha amancane, imihuzuko, kanye nokungalingani. Izinto ezibrasive ezisetshenziswa kakhulu yi-alumina, i-silicon carbide, kanye nama-silica compounds ahlanzekile kakhulu. Ukukhethwa kohlobo lwe-abrasives, usayizi wezinhlayiya, kanye nokuhlushwa kuncike ebulukhunini be-granite kanye nokunemba okudingekayo kobuso. Ukuze kuqedwe kahle, ama-abrasives anosayizi wezinhlayiya ze-sub-micron asetshenziselwa ukufeza izindawo ezisicaba kakhulu ngaphakathi kokubekezelelana kwe-flatness okungu-1–2 µm.
Izinto zokupholisha zisetshenziswa ngemva kokugaya ukuze kuthuthukiswe ukushelela kobuso kanye nokucwebezela. Kulesi sigaba, umgomo awukona ukususwa kwezinto kodwa ukuhluzwa kokuthungwa kobuso obuncane. Izinto ezithuthukisiwe ezisekelwe ku-polyurethane, ama-acrylic compounds, kanye ne-chromium oxide zivame ukusetshenziswa ukukhiqiza ukuqeda okufana nesibuko. Ibhalansi efanele phakathi kokucindezela, isivinini, kanye nokwakheka kwe-agent kubalulekile ekufinyeleleni ukukhanya okufanayo ngaphandle kokubeka engcupheni ukunemba.
Okokugcina, ama-sealant asetshenziswa njengesendlalelo sokuvikela uma ukupholisha sekuqediwe. I-Granite ngokwayo imelana kakhulu nokugqwala nokushintshashintsha kwezinga lokushisa, kodwa ukusebenzisa i-sealant efanele kuthuthukisa ukumelana namanzi, uwoyela, nothuli ngenkathi kugcinwa ukuzinza kokukhanya nokwemishini kwepulatifomu. Abakhiqizi abangochwepheshe bavame ukusebenzisa ama-sealant asekelwe ku-polymer noma ku-wax ukuqinisekisa ukuvikelwa kwesikhathi eside, ikakhulukazi ezindaweni ezinomswakama ophezulu noma zelebhu.
Lapho begaya futhi bepholisha i-granite, abaqhubi kumele baqinisekise ukuthi izinga lokushisa nomswakama kusezingeni elilawulwayo—ngokuvamile okungu-20 ± 1 °C—ukuvimbela ukuguquka kokushisa. Ukusebenzisa amanzi ahlanzekile noma uketshezi lokupholisha olungathathi hlangothi nakho kuyanconywa ukuze kugwenywe ukungcola. Ukugcinwa njalo, okuhlanganisa ukuhlanza nokuhlola ipuleti elingaphezulu, kusiza ukugcina ukunemba kwalo nokwandisa isikhathi salo sokusebenza.
Ekuphetheni, ukufeza ukuqeda okungenaphutha epuletini lobuso be-granite elinembile kuncike ekukhetheni okunembile kanye nokusetshenziswa kobungcweti koketshezi kanye nama-ejenti okupholisha. Isigaba ngasinye—kusukela ekuhlanzeni kuya ekuvaleni—sidinga ubuchwepheshe, ukunaka imininingwane, kanye nokulawula okuqinile kwemingcele yenqubo. Uma kwenziwa kahle, umphumela uba yipulatifomu ye-granite enesicaba esiyingqayizivele, ukushelela, kanye nokuqina—okuqinisekisa ukusebenza okuthembekile kokulinganisa okunembile kanye nezicelo zokukhiqiza ezisezingeni eliphezulu.
