Kuchuluka kwa ntchito
- Malo osangalatsa ndi nyumba zogona, malo a anthu, nyumba zamagulu ndi nyumba zamalonda;
- Mafakitole amakina, mafakitale a mankhwala, magalaja, malo osungira, malo osungira katundu, mafakitale osindikizira;
- Malo ochitira zisudzo, zipinda zamainjini, ndi makina apansi m'malo apadera.
Makhalidwe amachitidwe
- Maonekedwe athyathyathya komanso okongola, mpaka magalasi:
- Mphamvu yayikulu, kuuma kwakukulu, kukana kwamphamvu kwa abrasion;
- Kumamatira kwamphamvu, kusinthasintha kwabwino komanso kukana kwamphamvu;
- Kugonjetsedwa ndi madzi, mafuta, asidi, alkali ndi zina zambiri mankhwala dzimbiri;
- Palibe seams, zosavuta kuyeretsa, zosavuta kukonza.
Makhalidwe adongosolo
- Zosungunulira, zamtundu wolimba, zonyezimira;
- makulidwe 2-5 mm;
- Moyo wautumiki wanthawi zonse ndi wopitilira zaka 10.

Ntchito yomanga
- Plain nthaka mankhwala: mchenga woyera, m'munsi pamwamba amafuna youma, lathyathyathya, opanda ng'oma, palibe mchenga kwambiri;
- Choyambira: chigawo chapawiri malinga ndi kuchuluka kwachulukidwe kokhazikika (kuzungulira kwamagetsi kwa mphindi 2-3), ndi chodzigudubuza kapena scraper;
- Mu utoto matope: magawo awiri molingana ndi kuchuluka kwa mchenga wa quartz wosonkhezera (kuzungulira kwamagetsi kwa mphindi 2-3), ndi zomangamanga;
- Mu utoto putty: magawo awiri molingana ndi kuchuluka komwe kwachitika (kuzungulira kwamagetsi kwa mphindi 2-3), ndikumanga ndi scraper;
- Chovala chapamwamba: chodzikongoletsera chodziyimira pawokha komanso chochiza malinga ndi kuchuluka kwa chipwirikiti (kuzungulira kwamagetsi kwa mphindi 2-3), ndikupopera kapena kukanda tsamba lopanga mano.
