Q: Kuv muaj ib lub laj kab qub uas tsis tau pleev xim rau. Kuv yuav pleev xim nws nrog terrace latex xim. Kuv npaj yuav ntxuav nws nrog TSP (Trisodium Phosphate) thiab tom qab ntawd siv cov pob zeb sib txuas ua ke. Kuv puas yuav tsum tau etch ua ntej thov primer?
Teb: Nws yog qhov zoo kom ceev faj thaum ua cov kauj ruam npaj tsim nyog. Kev pleev xim rau lo rau hauv pob zeb yog qhov nyuaj dua li ua rau ntoo. Qhov kawg uas koj xav tau yog xim tev, tshwj xeeb tshaj yog ntawm cov porches uas tau muaj sia nyob tsis muaj xim nyob rau xyoo no.
Thaum cov xim tsis lo rau lub pob zeb zoo, nws yog qee zaum vim tias ya raws nkag los ntawm cov pob zeb hauv qab. Txhawm rau kuaj xyuas, tso ib qho tuab tuab ntawm cov yas ntshiab (xws li 3-nti square txiav los ntawm lub hnab yas rov qab) rau ntawm thaj chaw uas tsis tau pleev xim. Yog tias dej poob rau hnub tom qab, koj tuaj yeem xav tawm ntawm lub sam thiaj li nws yog.
Lwm qhov laj thawj tseem ceeb vim li cas cov xim qee zaum tsis lo rau hauv pob zeb: qhov saum npoo yog du thiab ntom. Tus installer feem ntau smears pob zeb rau ntawm lub sam thiaj thiab hauv pem teb los tsim cov xuab zeb zoo heev coated nrog grout. Qhov no ua rau saum npoo denser dua li cov pob zeb ntxiv hauv cov slab. Thaum cov pob zeb tshwm nyob rau hauv huab cua, qhov saum npoo yuav ua rau lub sijhawm dhau mus, uas yog vim li cas koj tuaj yeem pom feem ntau pom cov xuab zeb thiab txawm tias pob zeb ntawm cov pob zeb qub thiab cov terraces. Txawm li cas los xij, ntawm lub sam thiaj, cov xim ntawm qhov chaw yuav luag zoo li tuab thiab zoo ib yam li thaum lub pob zeb tau nchuav. Etching yog ib txoj hauv kev kom roughen saum npoo thiab ua kom cov xim zoo dua.
Tab sis cov khoom etching tsuas yog ua haujlwm yog tias cov pob zeb huv si thiab tsis muaj coated. Yog tias cov pob zeb pleev xim rau xim, koj tuaj yeem pom cov xim tau yooj yim, tab sis lub sealant uas tseem tiv thaiv cov xim los ntawm lo yuav pom tsis tau. Ib txoj hauv kev los ntsuam xyuas lub sealant yog ncuav ib co dej. Yog tias nws nkag mus rau hauv dej, lub pob zeb yog liab qab. Yog hais tias nws tsim ib tug puddle rau ntawm qhov chaw thiab nyob twj ywm ntawm qhov chaw, nws yog assumed tias lub nto yog kaw.
Yog tias dej nkag mus rau hauv dej, xaub koj txhais tes hla saum npoo av. Yog tias qhov kev ntxhib los mos zoo ib yam li cov ntawv nruab nrab mus rau ntxhib xuab zeb (150 grit yog cov lus qhia zoo), koj yuav tsis tas yuav etch, txawm tias nws yuav tsis raug mob. Yog hais tias qhov saum npoo yog du, nws yuav tsum tau etched.
Txawm li cas los xij, yuav tsum muaj cov kauj ruam etching tom qab ntxuav cov pob zeb. Raws li cov neeg ua haujlwm pabcuam kev pabcuam ntawm Savogran Co. (800-225-9872; savogran.com), uas ua rau ob yam khoom no, TSP thiab TSP lwm txoj hauv kev kuj tsim nyog rau lub hom phiaj no. Ib phaus ntawm ib lub thawv ntawm TSP hmoov tsuas yog nqi $ 3.96 ntawm Tsev Depot, thiab nws yuav txaus, vim tias ib nrab khob ntawm ob nkas loos dej tuaj yeem ntxuav txog 800 square feet. Yog tias koj siv lub tshuab nqus tsev siab, ib lub quart ntawm cov kua TSP hloov lub tshuab nqus tsev ntxhua khaub ncaws, tus nqi ntawm $ 5.48, yuav siv tau yooj yim dua thiab tuaj yeem ntxuav tau txog 1,000 square feet.
Rau etching, koj yuav pom cov khoom tsis meej pem, suav nrog cov qauv hydrochloric acid thiab cov khoom xws li Klean-Strip Green Muriatic Acid ($ 7.84 ib nkas loos rau Tsev Depot) thiab Klean-Strip Phosphoric Prep & Etch ($ 15.78 ib nkas loos). Raws li Lub tuam txhab cov neeg ua haujlwm pabcuam kev pabcuam tau hais tias "ntsuab" hydrochloric acid muaj qhov tsis tshua muaj siab thiab tsis muaj zog txaus los khawb cov pob zeb ua kom zoo. Txawm li cas los xij, yog tias koj xav etch pob zeb uas xav tias ntxhib me ntsis, qhov no yog qhov kev xaiv zoo. Phosphoric acid yog haum rau cov pob zeb du lossis ntxhib, tab sis koj tsis xav tau nws cov txiaj ntsig loj, uas yog, nws tsim nyog rau pob zeb thiab xeb hlau.
Rau txhua yam khoom etching, nws yog ib qho tseem ceeb heev uas yuav tsum ua raws li tag nrho cov kev ceev faj txog kev nyab xeeb. Hnav tag nrho lub ntsej muag lossis ib nrab lub ntsej muag ua pa nrog cov kua qaub-tiv taus, tsom iav, tshuaj tiv thaiv cov hnab looj tes npog lub hauv pliaj, thiab khau looj plab hlaub. Siv cov tshuaj tsuag yas tuaj yeem siv rau cov khoom siv, thiab siv cov txhuam hniav uas tsis yog xim hlau los yog txhuam nrog tus kov los siv cov khoom rau saum npoo. Lub tshuab nqus tsev siab yog qhov zoo tshaj plaws rau kev tso dej, tab sis koj tuaj yeem siv lub hose. Nyeem daim ntawv ua tiav ua ntej qhib lub thawv.
Tom qab etching lub pob zeb thiab cia nws qhuav, so nrog koj txhais tes los yog ib daim ntaub dub kom paub tseeb tias nws tsis muaj plua plav. Yog tias koj ua, yaug dua. Tom qab ntawd koj tuaj yeem npaj cov primer thiab pleev xim.
Ntawm qhov tod tes, yog tias koj pom tias koj lub qab nthab raug kaw, koj muaj ntau txoj kev xaiv: tshem cov sealant nrog cov tshuaj, zom tawm ntawm qhov chaw kom nthuav tawm cov pob zeb tawg lossis rov xav txog koj cov kev xaiv. Tshuaj tev thiab sib tsoo yog qhov teeb meem tiag tiag thiab tho txawv, tab sis nws yooj yim los hloov rau cov xim uas sticks txawm ntawm cov pob zeb kaw. Behr Porch & Patio Pem Teb Xim zoo li yog hom khoom hauv koj lub siab, txawm tias koj siv primer, nws yuav tsis lo rau cov pob zeb kaw. Txawm li cas los xij, Behr's 1-thooj epoxy pob zeb thiab cov chaw nres tsheb hauv pem teb pleev xim yog qhov tsim nyog rau ncaj qha npog cov pob zeb ua ntej, muab koj ntxuav hauv pem teb, xuab zeb txhua qhov ci ntsa iab thiab khawb tawm ib qho kev sib khi. (Lub "ntub zoo li" pob zeb sealant tsim cov zaj duab xis saum npoo uas tuaj yeem tev tawm, thaum nkag mus rau lub sealant yuav tsis hloov qhov tsos thiab tsis tev tawm.)
Tab sis ua ntej koj cog lus tias yuav pleev xim rau tag nrho lub qab nthab nrog cov khoom no lossis cov khoom zoo sib xws, pleev xim rau thaj tsam me me thiab xyuas kom koj txaus siab rau qhov tshwm sim. Hauv Behr lub vev xaib, tsuas yog 62% ntawm 52 tus neeg tshuaj xyuas tau hais tias lawv yuav pom zoo cov khoom no rau cov phooj ywg. Qhov ntsuas nruab nrab ntawm Lub Tsev Depot lub vev xaib yog kwv yees li qub; ntawm ntau tshaj 840 tus neeg saib xyuas, ze li ib nrab muab nws tsib lub hnub qub, uas yog qhov ntsuas siab tshaj plaws, thaum txog ib lub hlis twg muab nws tsuas yog ib lub hnub qub. Yog qhov qis tshaj. Yog li ntawd, koj yuav txaus siab rau tag nrho thiab kev nyuaj siab tag nrho yuav yog 2 rau 1. Txawm li cas los xij, ntau qhov kev tsis txaus siab cuam tshuam nrog kev siv cov khoom hauv pem teb chaw nres tsheb, cov log tsheb yuav ua rau lub siab ua kom tiav, yog li koj tuaj yeem muaj txoj hauv kev zoo dua. zoo siab rau lub qab nthab.
Txawm li cas los xij, tseem muaj ntau yam teeb meem nrog kev pleev xim pob zeb. Txawm hais tias koj xaiv qhov twg tiav, lossis ceev faj npaum li cas hauv cov kauj ruam npaj, nws tseem yog qhov tsim nyog los pleev xim rau ntawm thaj chaw me me, tos ib pliag thiab xyuas kom cov khoom tiav. . Unpainted qhob ib txwm zoo dua li pob zeb nrog cov xim pleev xim.
