putty yemadziro
Sekureva kwevashandisi vayo, inowanzo kamurwa kuita mhando mbiri: putty isina kupedzwa uye putty yakasanganiswa yakaoma. Putty isina kupedzwa haina kurongedza kwakasimba, haina mwero wekugadzira wakafanana, uye haina vimbiso yemhando. Inowanzogadzirwa nevashandi panzvimbo yekuvaka. Putty yakasanganiswa yakaoma inogadzirwa zvichienderana nehuwandu hwezvinhu hwakakodzera uye nzira yakagadzirwa nemichina, izvo zvinodzivirira kukanganisa kunokonzerwa nehuwandu hwenzvimbo yacho hwemaitiro echinyakare uye dambudziko rekuti mhando haigone kuvimbiswa, uye inogona kushandiswa zvakananga nemvura.
