Q: Peb muaj taub dag nplooj zeeg ua khoom dai rau ntawm peb lub rooj noj mov maple uas zoo li lub rooj, ua tiav tsuas yog nrog roj linseed, uas peb siv tsis tu ncua. Lub taub dag tau xau thiab tawm hauv qhov chaw. Puas muaj txoj hauv kev los tshem nws?
A: Muaj ntau txoj hauv kev los tshem tawm cov xim tsaus ntawm ntoo, tab sis koj yuav tsum sim ntau txoj kev daws teeb meem.
Feem ntau, cov xim tsaus ntawm ntoo yog vim muaj cov dej noo sib xyaw nrog cov tannins, uas tau txais lawv lub npe los ntawm cov tshuaj pom muaj nyob rau hauv cov tawv ntoo oak thiab ntoo oak thiab tau siv los ua kom tawv nqaij tan rau ntau txhiab xyoo. Tannins kuj pom muaj nyob rau hauv ntau yam txiv hmab txiv ntoo, zaub, thiab lwm yam khoom siv cog. Nws yog ib qho antioxidant thiab ntau txoj kev tshawb fawb tam sim no tsom mus rau cov teebmeem kev noj qab haus huv ntawm kev noj cov khoom noj uas muaj tannin ntau.
Cov tannins yaj tau hauv dej. Thaum cov ntoo ntub thiab cov dej ua pa, nws coj cov tannins mus rau saum npoo uas cov tannins tseem nyob. Qhov no feem ntau tshwm sim nrog cov ntoo uas muaj tannin ntau xws li ntoo oak, ntoo walnut, ntoo cherry, thiab ntoo mahogany. Maple muaj cov tannins tsawg heev, tab sis cov tannins hauv cov kua taub dag tej zaum yuav tau sib xyaw nrog cov tannins hauv ntoo maple los tsim cov xim av.
Cov xim tsaus ntawm ntoo kuj tuaj yeem yog vim pwm, uas tshwm sim thaum ntoo ntub thiab yog qhov chaw noj mov rau ntau yam pwm hu ua mildew lossis mildew. Ib yam li yuav luag txhua yam khoom siv organic, kua txiv taub dag yeej siv tau ua qhov chaw noj mov.
Oxalic acid tshem tawm cov tannin stains thiab chlorine bleach tshem tawm cov pwm stains. Oxalic acid yog ib qho khoom xyaw hauv Bar Keepers Friend Cleaner ($ 2.99 ​​ntawm Ace Hardware), tab sis nws ua rau tsawg dua 10 feem pua ​​​​​​ntawm cov khoom xyaw hauv lub kaus poom, raws li cov ntaub ntawv kev nyab xeeb ntawm cov chaw tsim khoom. Oxalic acid kuj pom muaj nyob rau hauv Bar Keepers Friend tshuaj ntxuav me me, tab sis ntawm qhov concentration qis dua. Rau daim ntawv tsis diluted, nrhiav cov khoom zoo li Savogran Wood Bleach ($ 12.99 rau 12-ounce tub ntawm Ace) hauv txoj kab xim.
Txawm li cas los xij, cov oxalic acid thiab bleach yuav tsum tau kov cov ntoo fibers kom ua haujlwm. Yog li ntawd, cov neeg kho rooj tog ua ntej tshem tawm qhov tiav nrog cov kuab tshuaj lossis xuab zeb. Txawm li cas los xij, nws yog qhov tseeb tias qhov xim tau nkag mus rau qhov tiav, yog li koj tuaj yeem dhia mus rau qhov oxalic acid taub hau hauv qab no kom pom tias muaj oxalic acid txaus tau nkag mus rau hauv kom txo qhov xim yam tsis tau tshem tawm. Ib qho web post uas kuv pom tau qhia cov duab kauj ruam los ntawm kauj ruam ntawm cov xim dub raug tshem tawm ntawm ntoo yam tsis tau tshem tawm nrog cov nplaum ntawm 2 qhov Bar Keepers Friend cleaner thiab 1 feem dej rau ob peb feeb, tom qab ntawd ib nrab ntxuav thiab ib nrab dej. Tus sau ntawm cov ntawv no siv 0000 cov hlau zoo ntxiv rau daim ntawv thov thib ob, tab sis nws yuav muaj kev nyab xeeb dua los siv cov ntaub pua plag hluavtaws. Cov hlau wool yuav tawm cov splinters hauv cov qhov hws ntawm ntoo, thiab cov tannins yuav cuam tshuam nrog hlau, tig cov ntoo uas nyob ib sab dub.
Yog koj ua tau qhov xim ntawd thiab koj txaus siab rau qhov tshwm sim, ces zoo kawg li! Txawm li cas los xij, nws yuav ua rau koj tsis tau txais cov xim zoo ib yam. Yog vim li ntawd cov kws tshaj lij thiaj li pom zoo kom tshem tawm cov xim tiav ua ntej, kho cov xim ntawd, thiab tom qab ntawd rov ua kom zoo nkauj dua.
Tej zaum cov tshuaj thinner yog txoj hauv kev zoo tshaj plaws los tshem tawm cov khoom qub vim tias qhov patina ntawm cov khoom qub yog qhov tseem ceeb. Carol Fiedler Kawaguchi, uas kho cov khoom qub thiab lwm yam rooj tog los ntawm nws lub tuam txhab C-Saw hauv Bainbridge Island, Washington, pom zoo kom siv cov tshuaj ntawm ib nrab denatured cawv thiab ib nrab lacquer thinner. Txhawm rau tiv thaiv koj tus kheej ntawm cov pa phem, ua haujlwm sab nraum zoov yog tias ua tau lossis hnav ib nrab-lub ntsej muag nrog lub lim dej organic vapor. Hnav cov hnab looj tes thiab cov tsom iav tiv thaiv tshuaj lom neeg. Cov kuab tshuaj no evaporate sai, yog li ua haujlwm hauv thaj chaw me me kom khawb tawm lossis rhuav tshem cov khoom nplaum ua ntej nws tawv.
Los yog, Kawaguchi hais tias, koj tuaj yeem siv Citristrip Safer Paint and Varnish Striping Gel ($ 15.98 ib liter ntawm Home Depot). Cov tshuaj stripper no tsis muaj ntxhiab, nyob ntub thiab ua haujlwm tau ntau teev, thiab muaj daim ntawv lo rau kev nyab xeeb rau kev siv sab hauv tsev. Txawm li cas los xij, raws li koj tuaj yeem pom los ntawm cov ntawv me me ntawm daim ntawv lo, xyuas kom muaj cua nkag tau zoo thiab hnav cov hnab looj tes thiab tsom iav tiv thaiv tshuaj lom neeg.
Yog tias koj xav kom tsis txhob muaj tshuaj lom neeg tawm, kev xuab zeb yog lwm txoj kev xaiv - qhov no tuaj yeem tshwj xeeb tshaj yog rau cov haujlwm uas tsis muaj cov khoom qub thiab muaj qhov chaw tiaj tus yam tsis muaj kev kos duab nyuaj uas yuav ua rau kev xuab zeb nyuaj. Siv lub tshuab xuab zeb orbital xws li 5″ DeWalt Corded Hook & Loop Sander ($ 69.99 ntawm Ace). Yuav ib pob ntawv xuab zeb nruab nrab ($ 11.99 rau 15 lub log xuab zeb Diablo) thiab tsawg kawg yog ob peb daim ntawv xuab zeb zoo (220 grit). Yog tias ua tau, txav lub rooj mus rau sab nraud lossis mus rau hauv lub tsev rau khoom kom cov ntoo chips tsis txhob hla mus rau txhua qhov chaw. Pib nrog ntawv xuab zeb nruab nrab. Roj linseed reacts nrog cov pa oxygen hauv huab cua los ua ib qho chaw yas. Qhov kev tshuaj tiv thaiv no ua tiav sai sai thaum xub thawj, tom qab ntawd qeeb qeeb thiab kav ntev rau ntau xyoo. Nyob ntawm seb qhov tiav nyuaj npaum li cas, koj tuaj yeem xuab nws yooj yim. Lossis, ib qho me me ntawm cov roj av yuav tsim rau ntawm ntawv xuab zeb, uas yuav txo nws qhov ua tau zoo. Tshawb xyuas ntawv xuab zeb ntau zaus thiab hloov nws raws li qhov xav tau.
Thaum koj tseem muaj ntoo liab qab, koj tuaj yeem daws qhov teeb meem ntawd. Sim siv oxalic acid ua ntej. Daim ntawv lo Savogran hais kom sib tov tag nrho lub thawv 12 ooj nrog 1 nkas loos dej kub, tab sis koj tuaj yeem zoom tawm thiab sib tov ib feem plaub ntawm cov ntsiab lus nrog 1 liv dej kub. Siv txhuam los nthuav cov tshuaj thoob plaws lub rooj, tsis yog tsuas yog qhov teeb meem xwb. Tos kom txog thaum ntoo tau sib dua raws li koj nyiam. Tom qab ntawd so ob peb zaug nrog daim ntaub huv si thiab ntub dej kom yaug qhov chaw. Tus kws tshaj lij npaj qhov chaw Jeff Jewitt hais hauv nws phau ntawv Making Furniture Refinishing Easy tias kev tshem tawm qhov teeb meem tuaj yeem xav tau ntau zaus kho nrog ob peb teev ntawm kev ziab ntawm nruab nrab.
Yog tias oxalic acid tsis tshem tawm cov xim av, sim siv cov tshuaj chlorine bleach rau cov xim av thiab cia ib hmos. Yog tias cov xim ploj me ntsis, tab sis tsis txaus, rov ua cov txheej txheem ntau zaus, tab sis tej zaum thoob plaws hnub kom koj tuaj yeem kuaj xyuas thiab ua tiav kev kho mob ua ntej cov ntoo hloov xim dhau. Thaum kawg, neutralize thiab yaug nrog 1 feem vinegar dawb thiab 2 feem dej.
Yog tias qhov xim tsis ploj mus, koj muaj peb txoj kev xaiv: hu rau tus kws pleev xim; muaj cov tshuaj dawb uas muaj zog dua, tab sis lawv tsis yog txhua lub sijhawm. Koj tuaj yeem xuab nws kom txog thaum qhov xim ploj mus, lossis tsawg kawg yog sib zog txaus kom nws tsis txhob cuam tshuam koj. Lossis npaj siv daim ntawv nruab nrab ua lub rooj.
Yog tias koj tau siv oxalic acid lossis bleach, tom qab cov ntoo qhuav lawm, yuav tsum tau xuab zeb zaum kawg nrog lub xuab zeb me me, xuab zeb zoo kom tshem tawm cov fibers uas tau ntab rau saum npoo vim yog dej sib cuag. Yog tias koj tsis xav tau lub sander los ntxuav thiab tsis muaj ib qho, koj tuaj yeem ua nws los ntawm tes nrog 220 grit sandpaper. Tshem tawm tag nrho cov hmoov av xuab zeb, tom qab ntawd koj tuaj yeem kov nrog roj linseed lossis lwm yam.
