Mashandisirwo ekushandisa
◇ Nzvimbo dzekuvaraidza nedzimba dzekugara, nzvimbo dzeveruzhinji, zvivakwa zve organ nezvivakwa zvemabhizinesi;
◇ Mafekitori emichina, mafekitori emakemikari, magaraji, madoko, maresitorendi, mafekitori ekudhinda;
◇ Dzimba dzemitambo, makamuri einjini, uye masisitimu epasi munzvimbo dzakakosha.
Zvinhu Zvinoita Basa
◇ Chitarisiko chakati sandara uye chakanaka, kusvika pagirazi:
◇ Simba guru, kuomarara kwakanyanya, kuramba kwakasimba kwekukwesha;
◇ Kunamatira kwakasimba, kuchinjika kwakanaka uye kuramba kukanganiswa;
◇ Haipindi ngura yemvura, mafuta, asidhi, alkali nezvimwe zvinhu zvinokanganisa ngura yemakemikari;
◇ Hapana misono, zviri nyore kuchenesa uye zviri nyore kugadzirisa.
Hunhu hwehurongwa
◇ Yakagadzirwa nezvinhu zvinonyungudutsa, ine ruvara rwakasimba, inopenya;
◇ Ukobvu 2-5mm;
◇ Hupenyu hwebasa remuchina 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.
