5. Kaho ea seretse se thibelang mapheo le lera le shebaneng
1) Qetello ea pente
2) Ka nako ena, hoa hlokahala ho sebelisa seretse se khahlanong le crack le ho beha lesela la letlooeng.Ka mor'a hore seretse sa anti-crack se sebelisoe, se hloka ho hlahlojoa ho bona hore na se behiloe fatše le hore na li-angles tse otlolohileng le tsa yin le yang li na le lisekoere.Libaka leha e le life tseo e seng tsa maemo li hloka ho tlatsoa hape le ho khangoa ka seretse.Joale, ka mor'a ho etsa mosebetsi o fetileng, sebelisa pente ea ho qetela.Emela ho fihlela seretse sa anti-crack se omme, ebe u se sebelisa.Ka nako ena, o boetse o lokela ho ela hloko boreleli.
3) Ho shebana le litene ho shebane
4) Mohato ona o hloka ho beha letlooeng le cheselitsoeng ka masenke a chesang.Ka mor'a hore lera la ho kenya letsoho le fete tlhahlobo ea kamohelo, sebelisa seretse se khahlanong le ho phunyeha ka makhetlo a mangata, ebe u beha letlooeng le entsoeng ka galvanized welded.Ka mor'a hore letlooa le cheselitsoeng le behoe, le boetse le hloka ho hlahlojoa ka nepo.Kamora ho feta tlhahlobo, seretse sa anti-crack se hloka ho sebelisoa.
5) Litene tsa Veneer
6) Ka mor'a hore mehato e fetileng ea mesebetsi ea kaho e phethoe, u ka lokisa litene tse shebaneng le nako ena.Botenya ba seretse ba litene tse shebaneng ka ho khetheha bo pakeng tsa 3mm-5mm.
