Q: Tili ndi sikwashi yokongoletsera patebulo lodyera la maple lomwe limapakidwa mafuta a linseed okha, omwe timapaka nthawi zonse. Dzungu linatuluka ndipo linasiya banga. Kodi pali njira yolichotsera?
Yankho: Pali njira zosiyanasiyana zochotsera mawanga akuda pamatabwa, koma mungafunike kuyesa njira zingapo zothetsera vutoli.
Nthawi zambiri madontho akuda pamatabwa amayamba chifukwa cha chinyezi chomwe chimabwera chifukwa cha ma tannins, otchedwa chifukwa cha kuchuluka kwa ma tannins omwe ali mu makungwa a oak ndi matabwa a oak, omwe akhala akugwiritsidwa ntchito kupukuta chikopa kwa zaka masauzande ambiri. Ma tannins amapezekanso mu zipatso, ndiwo zamasamba, ndi zinthu zina za zomera. Ndi antioxidant, ndipo kafukufuku wambiri waposachedwa akuyang'ana kwambiri pa zotsatira za kudya zakudya zokhala ndi tannin pa thanzi.
Ma tannins amasungunuka m'madzi. Pamene matabwa anyowa ndipo madzi akuphwanyika, amabweretsa ma tannins pamwamba, ndikusiya ma tannins ochulukirapo. Izi zimachitika nthawi zambiri m'nkhalango zokhala ndi ma tannins ambiri monga oak, walnut, cherry, ndi mahogany. Maple ali ndi ma tannins ochepa, koma mwina ma tannins omwe ali mu madzi a dzungu pamodzi ndi ma tannins omwe ali mu mapulo amapanga banga.
Madontho akuda pamatabwa amathanso kuchitika chifukwa cha nkhungu, yomwe imachitika pamene matabwa ali onyowa ndipo pali chakudya cha bowa lomwe timalitcha nkhungu kapena mildew. Madzi a dzungu, monga zosakaniza zonse zachilengedwe, angagwiritsidwe ntchito ngati chakudya.
Oxalic acid imachotsa madontho a tannin ndipo chlorine bleach imachotsa madontho a nkhungu. Oxalic acid ili mu Bar Keepers Friend Cleaner ($2.99 ​​​​pa Ace Hardware), koma imapanga zosakwana 10 peresenti ya phukusili, malinga ndi pepala lachitetezo la wopanga. Oxalic acid imapezekanso mu Bar Keepers Friend sopo wofewa, koma wochepa. Kuti mupeze mawonekedwe osasungunuka, yang'anani zinthu monga Savogran Wood Bleach ($12.99 pa bafa la ma ounces 12 kuchokera ku Ace) munjira yopaka utoto.
Komabe, kuti zigwire ntchito, oxalic acid ndi bleach ziyenera kukhudzana ndi ulusi wa matabwa. Chifukwa chake, okonza mipando choyamba amachotsa chophimba pamwamba ndi zosungunulira kapena kupukuta. Komabe, n'zoonekeratu kuti bangalo lafika kumapeto, kotero mutha kulumphira mwachangu ku nsonga ya oxalic acid pansipa kuti muwone ngati oxalic acid yokwanira yalowa kuti muchepetse bangalo popanda kuchotsa. Positi yomwe ndapeza pa intaneti idawonetsa zithunzi pang'onopang'ono zomwe zikuwonetsa momwe madontho akuda amachotsedwera pamatabwa popanda kuchotsa, pogwiritsa ntchito phala la magawo awiri a Bar Keepers Friend cleaner ndi gawo limodzi la madzi, ndikusakaniza kwa mphindi zochepa, kenako pogwiritsa ntchito theka la sopo ndi theka la madzi. Wolemba nkhaniyi adagwiritsa ntchito ubweya wachitsulo wowonjezera wa 0000 pakugwiritsa ntchito kachiwiri, koma zingakhale bwino kugwiritsa ntchito pedi yopangira. Ubweya wachitsulo udzasiya zidutswa m'mabowo a matabwa, ndipo ma tannins adzagwirizana ndi chitsulo, ndikusandutsa matabwa oyandikana nawo kukhala akuda.
Ngati mungathe kuthana ndi banga ndipo mukusangalala ndi zotsatira zake, zabwino kwambiri! Koma, mwina simudzatha kupeza mtundu wofanana. Ichi ndichifukwa chake akatswiri amalimbikitsa kuchotsa utoto womalizidwa ndi kuyeretsa banga musanamalizenso.
Pa zinthu zakale, zinthu zosungunulira ndi zabwino kwambiri chifukwa ndikofunikira kusunga patina. Carol Fiedler Kawaguchi, yemwe amakonza zinthu zakale ndi mipando ina kudzera mu kampani yake ya C-Saw ku Bainbridge Island, Washington, akulangiza njira yothetsera yomwe ili ndi theka la mowa wosungunuka ndi theka la lacquer. Kuti mudziteteze ku utsi, gwirani ntchito panja nthawi iliyonse yomwe mungathe kapena valani chopumira chokhala ndi katiriji ya nthunzi ya organic. Valani magolovesi ndi magalasi oteteza mankhwala. Zinthu zosungunulirazi zimaphwa msanga, choncho gwiritsani ntchito magulu ang'onoang'ono kuti mukweze kapena kupukuta pamwamba pake pouma musanaume.
Kapena, Kawaguchi akuti, mungagwiritse ntchito Citristrip Safer Paint ndi Varnish Striping Gel ($15.98 pa lita imodzi ku Home Depot). Chotsukira ichi sichinunkhiza, chimakhala chonyowa komanso chogwira ntchito kwa maola ambiri, ndipo chimalembedwa kuti ndi chotetezeka kugwiritsidwa ntchito m'nyumba. Komabe, monga momwe chizindikirocho chikusonyezera, onetsetsani kuti mpweya wabwino ukuyenda bwino ndipo valani magolovesi ndi magalasi oteteza ku mankhwala.
Kusambitsa ndi njira ina ngati mukufuna kupewa kuchotsa mankhwala. Izi zitha kukhala zokopa makamaka kwa mapulojekiti omwe si akale komanso okhala ndi malo athyathyathya opanda mapangidwe ovuta omwe amapangitsa kuti kusambitsa kukhale kovuta. Gwiritsani ntchito sander yosasinthika ya orbital, monga DeWalt Corded 5-inch hook-and-loop pad sander ($69.99 pa Ace). Gulani paketi ya sandpaper yapakati ($11.99 pa ma disc 15 a Diablo sanding) ndi mapepala ochepa a sandpaper yabwino (220 grit). Ngati n'kotheka, sunthani tebulo kunja kapena mu garaja kuti zidutswa zamatabwa zisalowe paliponse. Yambani ndi pepala lapakati. Mafuta a flaxseed amachitapo kanthu ndi mpweya womwe uli mumlengalenga, ndikupanga chophimba chonga pulasitiki. Izi zimachitika mwachangu poyamba, kenako zimachepa ndipo zimatha kwa zaka zambiri. Kutengera momwe kumaliza kulili kolimba, mutha kuisambitsa mosavuta. Kupanda kutero, mipira yaying'ono yamafuta ingapangidwe pa sandpaper, zomwe zimachepetsa mphamvu yake. Yang'anani sandpaper pafupipafupi ndikuisintha ngati pakufunika.
Mukafika pamtengo wopanda kanthu, mutha kuthana ndi banga. Yesani kaye oxalic acid. Chizindikiro cha Savogran chimati sakanizani chidebe chonse cha ma ounces 12 ndi galoni imodzi ya madzi otentha, koma mutha kukulitsa ndikusakaniza kotala la zomwe zili mkati ndi lita imodzi ya madzi otentha. Gwiritsani ntchito burashi kuti muyike yankho pa kauntala yonse, osati banga lokha. Yembekezerani mpaka matabwa atazimiririka momwe mukufunira. Kenako pukutani kangapo ndi nsalu yoyera, yonyowa, ndikutsuka pamwamba pake. Malinga ndi katswiri wokonzanso zinthu Jeff Jewitt m'buku lake lakuti Upgrading Furniture Made Easy, zingatenge nthawi zingapo kuti muchotse banga, ndi maola angapo owuma pakati.
Ngati oxalic acid sichotsa banga, yesani kugwiritsa ntchito chlorine bleach pa bangalo ndipo musiye usiku wonse. Ngati mtundu watha pang'ono, koma osati kwathunthu, bwerezani njirayi kangapo, koma mwina tsiku lonse kuti muthe kuyang'ana ndikumaliza chithandizo nthawi zonse matabwa asanayambe kusinthika kwambiri. Pomaliza, yeretsani ndi kuyeretsa ndi viniga woyera gawo limodzi ndi magawo awiri a madzi.
Ngati banga silikutha, muli ndi njira zitatu: imbani katswiri wopaka utoto; pali ma bleach olimba, koma nthawi zonse sapezeka. Muthanso kupukuta mpaka banga litatha, kapena kuyatsa mokwanira kuti lisakuvutitseni. Kapena konzani kupanga pakati pa tebulo lodyera.
Ngati mwagwiritsa ntchito oxalic acid kapena bleach, matabwa akauma, muyenera kupukuta pang'ono ndi mchenga wosalala kuti muchotse ulusi womwe wayandama pamwamba kuti usakhudze madzi. Ngati simukufuna sander kuti muyeretse ndipo mulibe, mutha kuchita izi ndi dzanja ndi sandpaper ya grit 220. Fumbi lonse la sandling likachotsedwa, mwakonzeka kukhudza pamwamba ndi mafuta a linseed kapena china chilichonse.
