3. Kuramba Kunoshamisa Kwekupisa Kwekupisa:Inotsungirira kupisa/kutonhodza nekukurumidza, inowedzera hupenyu hwekushanda kwejira
4. Kugadzikana Kwevhoriyamu Yakanaka:Kuomesa zvishoma uye kupfuta zvishoma, hapana mipata yemajoini
5. Inodzivisa mhepo uye ngura:Inodzivirira kubuda kwegasi rinopisa, inodzivirira ngura, acid uye alkali
6. Kuvaka Kuri Nyore:Kukwesha troweli kwakapfava, kuvaka nekukurumidza, kwakakodzera kushandiswa nemaoko uye semi-mechanized masonry
7. Mafomu Anogona Kugadziriswa:Yakagadzirirwa mhando dzakasiyana dzechoto, zvinhu zvezvidhinha uye mamiriro ekushanda
