- Ukuhlolwa kweCandelo: Ngaphambi kokufaka amandongomane angangeni manzi, jonga ngononophelo amandongomane, iibholiti, kunye nezinto ezidityanisiweyo zokonakaliswa, ii-burrs, kunye nezinye iziphene. Ezi ziphene zinokuchaphazela ukusebenza kokutywinwa kunye nokulula kokufakela. Amalungu anesiphene kufuneka alungiswe okanye atshintshwe ngokukhawuleza.
- Ukucocwa koMphezulu: Qinisekisa ukuba imiphezulu yeendongomane, iibholiti, kunye neendawo eziqhagamshelayo zicocekile kwaye azinaoli, uthuli, kunye nobunye ukungcola. I-oyile kunye nothuli kunokuchaphazela ukulungelelaniswa kwe-sealant kwindawo yecandelo, ukunciphisa umphumo wokuthintela amanzi. Coca umphezulu ngelaphu elicocekileyo okanye isicoci esikhethekileyo, uze womise umoya ngomoya owomileyo.
- Ukukhetha iNuthi eFanelekileyo yokungangenwa ngamanzi: Khetha iindongomane ezingangeni manzi ezineenkcukacha ezifanelekileyo, izixhobo, kunye neentlobo zokutywina ngokusekelwe kwimeko yokusetyenziswa yokwenyani kunye neemfuno zoqhagamshelo. Izicelo ezahlukeneyo zifuna amabakala ahlukeneyo okuthintela amanzi, ukumelana nobushushu, kunye nokumelana neekhemikhali. Umzekelo, kwindawo -eziphezulu zobushushu, amandongomane angangeni manzi enziwe ngezinto ezikwaziyo ukumelana nobushushu{4} kufuneka akhethwe; kwiindawo eziphantsi kwe-asidi kunye ne-alkali corrosion, amantongomane ane-asidi kunye nokumelana ne-alkali kufuneka kukhethwe.
