Chikamu chekushandisa
◇ Inoshandiswa munzvimbo dzebasa umo nharaunda inoda kuramba kubvongodzwa, kukanganiswa uye kumanikidza kunorema.
◇ Mafekitari emichina, mafekitari emakemikari, magaraji, mafekitari, mashopu anotakura mitoro, mafekitari okudhinda;
◇ Nzvimbo dzepasi dzinoda kushingirira marudzi ese emarori eforogo uye mota dzinorema.
Maitiro ekuita
◇ Chitarisiko chakati sandara uye chinopenya, mavara akasiyana.
◇ Kusimba kwepamusoro, kuoma kwakakwirira, kusakara kwakasimba.
◇ Kunamira kwakasimba, kuchinjika kwakanaka uye kupikisa kuramba.
◇ Yakati sandarara uye isina musono, yakachena uye isingapindi guruva, iri nyore kuchenesa nekuchengetedza.
◇ Kuvaka nekukurumidza uye mutengo wemari.
Maitiro ehurongwa
◇ Kunyungudika, kusimba kweruvara, kupenya.
◇ Hukobvu 1-5mm.

Kuvaka nzira
1. Plain ground treatment: jecha rakachena, chigadziko chepasi chinoda kuoma, chakati sandara, hapana chigubhu chisina mhango, hapana jecha rakakomba;
2. Primer: kaviri chikamu maererano nehuwandu hwakatarwa hwekuenzana kutenderera (magetsi kutenderera 2-3 maminitsi), ine roller kana scraper kuvaka;
3. Mumatope epende: chikamu chezvikamu zviviri maererano nehuwandu hwehuwandu hwejecha re quartz (kutenderera kwemagetsi kwema 2-3 maminetsi), nekuvakwa kwe scraper;
4. Mupendi putty: maviri-chikamu kuenzanirana maererano nehuwandu hwakatarwa hwekusimudzira (magetsi kutenderera 2-3 maminitsi), ine scraper kuvaka;
5. Jasi repamusoro: mumiriri wemavara uye mumiriri wekurapa zvinoenderana nehuwandu hwakatarwa hwekuyeresa mutsauko (yemagetsi kutenderera 2-3 maminetsi), nekukunguruka kana kupfapfaidza kuvaka.
