Umbuzo: Ndineveranda yesamente endala engazange yaqatywa. Ndizakuyipeyinta ngepeyinti yelateksi yelateksi. Ndiceba ukuyicoca nge-TSP (i-Trisodium Phosphate) kwaye emva koko ndisebenzise i-primer yokudibanisa ikhonkrithi. Ngaba kufuneka ndifake i-etch ngaphambi kokufaka i-primer?
Impendulo: Kububulumko ukulumka xa usenza amanyathelo ayimfuneko okulungiselela. Ukufumana ipeyinti ukunamathela kwikhonkrithi kunzima kakhulu kunokuncamathela emthini. Into yokugqibela oyifunayo kukuxobula ipeyinti, ngakumbi kwiiveranda eziye zasinda ngaphandle kwepeyinti kule minyaka.
Xa ipeyinti ingabambeleli kakuhle kwikhonkrithi, ngamanye amaxesha ngenxa yokuba umswakama ungena ngekhonkrithi ukusuka ngaphantsi. Ukujonga, beka iqhekeza elishinyeneyo leplastiki ecacileyo (efana ne-3-intshi yesikwere esisikwe kwisingxobo seplastiki esiphinda sivaleleke) kwindawo engapeyintwanga. Ukuba amathontsi amanzi avela ngosuku olulandelayo, unokufuna ukushiya ivaranda njengoko injalo.
Esinye isizathu esibalulekileyo sokuba ipeyinti ngamanye amaxesha ayibambeleli kwikhonkrithi: umphezulu ugudileyo kwaye uxinene. Umfakeli udla ngokuthambisa ikhonkrithi kwiveranda naphantsi ukuze enze isanti entle kakhulu eqatywe ngegrout. Oku kwenza umphezulu uxinene kunekhonkrithi ngakumbi kwi-slab. Xa kukho ikhonkrithi kwimozulu, umphezulu uya kuguga ngokuhamba kwexesha, yiyo loo nto uhlala ubona isanti evelileyo kunye negrabile kwiindlela zekhonkrithi ezindala kunye namathafa. Nangona kunjalo, kwiveranda, umbala womphezulu unokuba phantse uxinene kwaye ufane njengaxa kugalelwa ikhonkrithi. I-Etching yindlela yokwenza rhabaxa umphezulu kwaye wenze ipeyinti ibambelele ngcono.
Kodwa iimveliso ze-etching zisebenza kuphela ukuba ikhonkrithi icocekile kwaye ayigqunywanga. Ukuba ikhonkrithi ipeyintiwe ngepeyinti, unokuyibona ngokulula ipeyinti, kodwa isitywina esikwanqanda ukuncamathela kwepeyinti sisenokungabonakali. Enye indlela yokuvavanya i-sealant kukugalela amanzi. Ukuba iyatshona emanzini, ikhonkrithi ayinanto. Ukuba yenza i-puddle phezu komhlaba kwaye ihlale phezu komhlaba, kucingelwa ukuba umphezulu uvalwe.
Ukuba amanzi atshona emanzini, tyibilikisa isandla sakho phezu komhlaba. Ukuba ukuthungwa kufana ne-sandpaper ephakathi ukuya kwi-rough (i-150 grit isikhokelo esihle), akufuneki ukuba udibanise, nangona ngokuqinisekileyo ayiyi kulimala. Ukuba ubuso bugudileyo, kufuneka bufakwe.
Nangona kunjalo, inyathelo le-etching liyafuneka emva kokucoca ikhonkrithi. Ngokutsho kwabasebenzi boncedo lobugcisa be-Savogran Co. (800-225-9872; savogran.com), evelisa ezi mveliso zimbini, ezinye iindlela ze-TSP kunye ne-TSP nazo zifanelekile kule njongo. Iponti yebhokisi ye-TSP yomgubo ixabisa i-$ 3.96 kuphela kwi-Home Depot, kwaye inokwanela, kuba isiqingatha sekomityi yeelitha ezimbini zamanzi sinokucoca malunga neenyawo ze-800. Ukuba usebenzisa isicoci soxinzelelo oluphezulu, ikota yesicoci solwelo se-TSP solwelo, esixabisa i-5.48 yeedola, kuya kuba lula ukuyisebenzisa kwaye inokucoca malunga ne-1,000 yeenyawo zesikwere.
Kuba etching, uya kufumana uthotho lweemveliso edidayo, kubandakanywa hydrochloric acid eqhelekileyo kunye neemveliso ezifana Klean-Strip Green Muriatic Acid ($ 7.84 nganye galoni for Home Depot) kunye Klean-Strip Phosphoric Prep & Etch ($ 15.78 ngegaloni). Ngokutsho kwabasebenzi boncedo lobugcisa benkampani bathi i-hydrochloric acid "eluhlaza" yayinoxinzelelo oluphantsi kwaye yayingomelelanga ngokwaneleyo ukuba ifake ikhonkrithi egudisiweyo. Nangona kunjalo, ukuba ufuna ukufaka ikhonkrithi eziva irhabaxa, olu lukhetho oluhle. I-asidi ye-Phosphoric ifanelekile kwikhonkrithi egudileyo okanye erhabaxa, kodwa awudingi inzuzo yayo enkulu, oko kukuthi, ifanelekile kwikhonkrithi kunye nentsimbi enomhlwa.
Kuyo nayiphi na imveliso etching, kubaluleke kakhulu ukulandela zonke izilumkiso zokhuseleko. Nxiba izinto zokuphefumla zobuso ezigcweleyo zobuso okanye ezinesiqingatha ezineasidi-residi, iiglasi, iiglavu ezikwaziyo ukumelana neekhemikhali ezigquma iingalo, kunye neebhutsi zerabha. Sebenzisa inkonkxa yokutshiza yeplastiki ukufaka imveliso, kwaye usebenzise umtshayelo ongeyontsimbi okanye ibhrashi enesiphatho ukuze usebenzise imveliso kumphezulu. Isicoci esinoxinzelelo oluphezulu silungele ukugungxulwa, kodwa ungasebenzisa ithumbu. Funda ileyibhile epheleleyo phambi kokuba uvule isikhongozeli.
Emva kokutshiza ikhonkrithi kwaye uyiyeke yome, yisule ngezandla zakho okanye ngelaphu elimnyama ukuze uqiniseke ukuba ayifumani naluphi na uthuli. Ukuba wenza njalo, hlambulula kwakhona. Emva koko unokulungiselela i-primer kunye nokudweba.
Kwelinye icala, ukuba ufumanisa ukuba iveranda yakho itywiniwe, unokhetho oluninzi: susa i-sealant ngeekhemikhali, ucole umphezulu ukuze uveze ikhonkrithi eveziweyo okanye uphinde ucinge ngokhetho lwakho. Ukuxobula imichiza kunye nokusila kuyingxaki ngokwenene kwaye kuyadika, kodwa kulula ukutshintshela kwipeyinti encamathela nakwikhonkrithi etywiniweyo. I-Behr Porch & Patio Floor Paint ibonakala iluhlobo lwemveliso engqondweni yakho, nokuba usebenzisa i-primer, ayiyi kunamathela kwikhonkrithi etywiniweyo. Nangona kunjalo, i-1-part ye-epoxy yekhonkrithi ye-Behr kunye nepeyinti yomgangatho wegaraji iphawulwe njengelungele ukugquma ikhonkrithi ebekade itywiniwe ngaphambili, ngaphandle kokuba ucoce umgangatho, wenze isanti kuyo nayiphi na indawo ekhazimlayo kwaye ukhuhle nasiphi na isitywina esixobukayo. (Isitywini sekhonkrithi "esimanzi" senza ifilim engaphezulu ekwazi ukuxobuka, ngelixa ukungena kwisitywina akusayi kutshintsha inkangeleko kwaye soze kuqhume.)
Kodwa ngaphambi kokuba uthembise ukupenda i-porch yonke ngale nto okanye nayiphi na imveliso efanayo, penda indawo encinci kwaye uqinisekise ukuba unelisekile ngesiphumo. Kwiwebhusayithi yeBehr, kuphela i-62% yababuyekezi be-52 bathi baya kucebisa le mveliso kubahlobo. Iireyithingi zomndilili kwiwebhusayithi yeHome Depot ziphantse zifane; phakathi kwababuyekezi abangaphezu kwe-840, phantse isiqingatha sabanika iinkwenkwezi ezintlanu, eyona nto iphezulu, ngelixa malunga nekota yanika inkwenkwezi enye kuphela. Yeyona iphantsi. Ngoko ke, amathuba akho okuba waneliseke ngokupheleleyo kwaye ucinezeleke ngokupheleleyo unokuba yi-2 ukuya ku-1. Nangona kunjalo, izikhalazo ezininzi zibandakanya ukusetyenziswa kwemveliso kumgangatho wegaraji, amavili emoto aya kufaka uxinzelelo ekugqibeleni, ukuze ube nethuba elingcono bevuya kwi veranda.
Nangona kunjalo, kusekho iingxaki ezininzi zokupeyinta ikhonkrithi. Kungakhathaliseki ukuba yiyiphi isiphelo osikhethayo, okanye ulumke kangakanani kumanyathelo okulungiselela, kusenobulumko ukupeyinta kwindawo encinci, linda ixesha elithile kwaye uqinisekise ukuba ukugqiba kunamathela. . Ikhonkrithi engapeyintwayo ihlala ikhangeleka ingcono kunekhonkrithi enepeyinti yokuxobula.
