Ruzivo rweChigadzirwa

Dhayi yesulfure nhema inowanzoshandiswa pakudhaya machira, kunyanya machira edonje. Heano matanho akajairika ekushandisa sulfur black: Gadzirira jira: Iva nechokwadi chekuti jira rakachena uye harina tsvina, mafuta, kana saizi inogona kukanganisa maitiro ekudhaya. Suka jira kana zvichidikanwa. Unganidza zvinhu zvinodiwa: Uchada dhayi nhema yesulfure, mudziyo wekudhaya (senge hari yesimbi isingatsvi), mvura, dhayi inogadzirisa (tarisa mirairo yemugadziri), uye magirovhosi (kudzivirira maoko ako).
Madhayi emapepa anoshandiswa kuwedzera ruvara pamapepa uye anowanzo shandiswa mumabasa emaoko, mapurojekiti eunyanzvi, uye maitiro ekugadzira. Anogona kuva muchimiro chemadhayi emvura, hupfu, kana mhinduro dzakasanganiswa. Madhayi emapepa akagadzirwa kuti anyungudike mumvura uye anowanzo shandiswa mukugadzira mapepa, kunyora mavara, uye kugadzira zvigadzirwa zvemapepa zvekushongedza. Anouya mumavara akasiyana-siyana anopenya uye anoshandiswa kuwedzera kutaridzika kwezvinhu zvakagadzirwa nemapepa. Kana uine mibvunzo chaiyo nezvekushandisa madhayi emapepa kana mashandisirwo awo, inzwa wakasununguka kukumbira rumwe ruzivo.
Kushandisa dhayi yemvura nhema kunogona kuva nzira inonakidza uye ine hunyanzvi yekuwedzera ruvara kumapurojekiti akasiyana-siyana, akadai sekudhaya machira, kudhaya tai, uye kunyange mabasa emaoko. Heano nhungamiro huru yekushandisa dhayi yemvura: Sarudza dhayi yakakodzera: Kune mhando dzakasiyana dzedhayi dzemvura dzekusarudza kubva, dzakadai sedhayi dzemachira, dhayi dzeacrylic, kana tsvuku yemvura yakagadzirwa nealcohol yekupenda mapepa. Ita shuwa kuti wasarudza dhayi inoenderana nezvinhu zvauri kushanda nazvo. Gadzirira nzvimbo yebasa: Gadzira nzvimbo yebasa yakachena uye ine mhepo inofefetera.
