Mashandisirwo ekushandisa
- Nzvimbo dzekuvaraidza nedzimba dzekugara, nzvimbo dzeveruzhinji, zvivakwa zve organ nezvivakwa zvemabhizinesi;
- Mafekitori emichina, mafekitori emakemikari, magaraji, zvikepe zvengarava, nzvimbo dzekutakura zvinhu, mafekitori ekudhinda;
- Makamuri ekushandisa ma "hwheat", makamuri einjini, uye masisitimu epasi munzvimbo dzakakosha.
Hunhu hwekushanda
- Chitarisiko chakati sandara uye chakanaka, kusvika pagirazi:
- Simba guru, kuomarara kwakanyanya, kuramba kwakasimba kwekukwesha;
- Kunamatira kwakasimba, kuchinjika kwakanaka uye kuramba kukanganiswa;
- Haina kukanganiswa nemvura, mafuta, asidhi, alkali nezvimwe ngura yemakemikari;
- Hapana misono, zviri nyore kuchenesa, zviri nyore kugadzirisa.
Hunhu hwehurongwa
- Yakagadzirwa nezvinhu zvinonyungudutsa, ine ruvara rwakasimba, inopenya;
- Ukobvu 2-5mm;
- Hupenyu hwebasa renguva dzose hunopfuura makore gumi.

Maitiro ekuvaka
- Kurapa pasi pasina kuvharwa: kucheneswa kwejecha, pasi pevhu panoda dhiramu rakaoma, rakati sandara, risina gomba, hapana kucheneswa kwakanyanya;
- Primer: chikamu chakapetwa kaviri zvichienderana nehuwandu hwakatarwa hwekusanganiswa kwakamutswa (kutenderera kwemagetsi kwemaminitsi 2-3), nekugadzirwa kweroller kana scraper;
- Mudhaka rependi: zvikamu zviviri zvinoenderana nehuwandu hwakatarwa hwejecha re quartz rakasanganiswa (kutenderera kwemagetsi kwemaminitsi 2-3), nekugadzirwa kwe scraper;
- Muputty yependi: zvikamu zviviri zvinoenderana nehuwandu hwakatarwa hwekukurunga (kutenderera kwemagetsi kwemaminitsi 2-3), nekugadzirwa kwescraper;
- Pepa repamusoro: chinhu chinoisa ruvara chinoyera uye chinogadzirisa ruvara zvichienderana nehuwandu hwakatarwa hwekukurunga (kutenderera kwemagetsi kwemaminitsi 2-3), uchishandisa banga rekupfapfaidza kana rekukwenya rine kuvakwa kwemazino.
