Ntchito yofunikira musanayambe kujambula

Kutsitsa pamwamba ndi njira yofunika kwambiri ngakhale pakukonza penti yaying'ono, osati penti yokha isanakwane.

Lamulo lalikulu ndiloti topcoat iyenera kuikidwa pamwamba pa primer, primer kapena pamwamba pa utoto wakale. Chitsulo chopanda kanthu sichiyenera kukhala ndi vanishi, chifukwa varnish sichimamatira bwino. Kuti muthe kumamatira bwino kwa varnish, tulutsani malo okonzedwa kale ndi mpweya woponderezedwa ndikuchotsa mafuta. Kuchotsa pamwamba kumaphatikizapo kufalitsa tizigawo ting'onoting'ono ta zosungunulira zopangidwira izi ndi nsalu yonyowa. Kenako, pogwiritsa ntchito nsalu youma ndi yoyera, pukutani chosungunuliracho chisanasanduke nthunzi. Chosungunulira chomwe chimagwiritsidwa ntchito potsitsa pamwamba sichiyenera kuchitapo kanthu. Amangoyenera kusungunula ma depositi amafuta pamenepo. Pukutani zosungunulira pamwamba ndi zolimbitsa thupi, popanda kukakamiza kwambiri pamwamba. Mwanjira iyi, njira yosungunulira evaporation imachedwa kuti mupeze zotsatira zabwino kwambiri zochotsera mafuta. Ngati simupukuta chosungunuliracho koma kungosiya kuti chiume kwathunthu, ma depositi amafuta sangachotsedwe pamwamba motere. 

Pamwamba payenera kuchotsedwa mafuta osati musanapente komanso musanapange mchenga. Choyamba, popanga mchenga pamalo osapaka mafuta, zotupa zimapangidwa kuchokera kumafuta ndi fumbi la mchenga. Ndiwo chifukwa cha zizindikiro zosiyana za mchenga. Nthawi yomweyo, abrasive amatha msanga. Kachiwiri, tinthu tating'onoting'ono tamafuta timakakamizika kulowa pamwamba pa mchenga ndi njere za abrasive, komwe zimakhala zovuta kuchotsa pambuyo pake.

M'mawu ena, kutsuka pamwamba ndi degreasing wothandizira facilitates ndi kufulumizitsa mchenga.
