Umbuzo: Nginompheme kakhonkolo omdala ongakaze upendwe. Ngizoyipenda ngopende we-latex wethala. Ngihlela ukuyihlanza nge-TSP (i-Trisodium Phosphate) bese ngifaka i-primer yokubopha ukhonkolo. Ingabe ngidinga uku-etch ngaphambi kokufaka i-primer?
Impendulo: Kuwukuhlakanipha ukuqapha lapho wenza izinyathelo ezidingekayo zokulungiselela. Ukuthola upende ukuze unamathele kukhonkolo kunzima kakhulu kunokunamathela okhunini. Into yokugcina oyifunayo ukucwecwa upende, ikakhulukazi kumaveranda asesinde ngaphandle kopende kule minyaka.
Lapho upende ungabambeleli kahle ukhonkolo, ngezinye izikhathi kungenxa yokuthi umswakama ungena ngokhonkolo kusuka ngezansi. Ukuze uhlole, beka ucezu oluwugqinsi lwepulasitiki ecacile (efana nesikwele esingu-3-intshi esisikwe esikhwameni sepulasitiki esivaleleka kabusha) endaweni engapendiwe. Uma amaconsi amanzi evela ngosuku olulandelayo, ungase ufune ukushiya kuvulandi njengoba kunjalo.
Esinye isizathu esibalulekile sokuthi kungani upende ngezinye izikhathi unganamatheli kukhonkolo: ubuso bushelelezi kakhulu futhi buminyene. Umfaki ngokuvamile ugcoba ukhonkolo kuvulandi naphansi ukuze akhe isihlabathi esihle kakhulu esimbozwe nge-grout. Lokhu kwenza ubuso buqine kunokhonkolo ngokuqhubekayo ku-slab. Uma ukhonkolo ubonakala esimweni sezulu, ingaphezulu lizowohloka ngokuhamba kwesikhathi, yingakho uvame ukubona isihlabathi esiveziwe ngisho netshe eliwubhuqu emigwaqweni endala yokukhonkolo nasezintabeni. Nokho, kuvulandi, umbala wendawo ungase ucishe ube minyene futhi ufane njengalapho kuthelwa ukhonkolo. I-Etching iyindlela yokuqinisa ubuso futhi wenze upende unamathele kangcono.
Kodwa imikhiqizo yokufaka i-etching isebenza kuphela uma ukhonkolo uhlanzekile futhi ungagqokile. Uma ukhonkolo upende ngopende, ungabona kalula upende, kodwa i-sealant evimbela upende ukuthi unganamatheli ingase ingabonakali. Enye indlela yokuhlola i-sealant ukuthela amanzi. Uma ishona emanzini, ukhonkolo ungenalutho. Uma yakha i-puddle ebusweni futhi ihlala phezulu, kucatshangwa ukuthi ingaphezulu livaliwe.
Uma amanzi eshona emanzini, shelelisa isandla sakho siwele phezulu. Uma ukuthungwa kufana ne-sandpaper ephakathi nendawo (i-grit engu-150 iyisiqondiso esihle), ungase ungadingi uku-etch, nakuba ngokuqinisekile ngeke ilimale. Uma ubuso bubushelelezi, kufanele buqoshwe.
Kodwa-ke, isinyathelo sokufaka siyadingeka ngemva kokuhlanza ukhonkolo. Ngokusho kwabasebenzi bosizo lobuchwepheshe be-Savogran Co. (800-225-9872; savogran.com), ekhiqiza le mikhiqizo emibili, ezinye izindlela ze-TSP ne-TSP nazo zifanelekile kule njongo. Iphawundi lebhokisi lempushana ye-TSP libiza kuphela u-$3.96 e-Home Depot, futhi lingase lanele, ngoba ingxenye yenkomishi yamalitha amabili amanzi ingahlanza cishe amafidi-skwele angu-800. Uma usebenzisa isicoci esinomfutho ophezulu, ilitha lesicoci se-TSP esiwuketshezi, esinenani elingu-$5.48, kuzoba lula ukusisebenzisa futhi singahlanza cishe amafidi-skwele angu-1,000.
Ukuze uhlanganise, uzothola uchungechunge lwemikhiqizo edidayo, ehlanganisa i-hydrochloric acid ejwayelekile kanye nemikhiqizo efana ne-Klean-Strip Green Muriatic Acid ($7.84 ilitha ngalinye le-Home Depot) kanye ne-Klean-Strip Phosphoric Prep & Etch ($15.78 ngegalani). Ngokusho kwabasebenzi bosizo lwezobuchwepheshe benkampani bathi i-hydrochloric acid “eluhlaza” yayinokugxila okuphansi futhi yayingenawo amandla anele okufaka ukhonkolo obushelelezi. Kodwa-ke, uma ufuna ukufaka ukhonkolo ozwakala kabi, lokhu kuyisinqumo esihle. I-Phosphoric acid ifanele ukhonkolo obushelelezi noma omaholoholo, kodwa awudingi inzuzo yayo enkulu, okungukuthi, ifanele ukhonkolo nensimbi egqwalile.
Kunoma imuphi umkhiqizo we-etching, kubaluleke kakhulu ukulandela zonke izinyathelo zokuphepha. Gqoka ama-respirators ebusweni agcwele ubuso noma uhhafu anezihlungi ezimelana ne-asidi, izibuko, amagilavu amelana namakhemikhali amboze izingalo, namabhuzu enjoloba. Sebenzisa ithini lepulasitiki lokufutha ukuze usebenzise umkhiqizo, futhi usebenzise umshanelo ongeyona insimbi noma ibhulashi elinesibambo ukuze usebenzise umkhiqizo phezulu. I-high-pressure cleaner ingcono kakhulu ukushaywa, kodwa ungasebenzisa futhi ipayipi. Funda ilebula ephelele ngaphambi kokuvula isiqukathi.
Ngemva kokucwilisa ukhonkolo futhi uwuyeke wome, wesule ngezandla zakho noma ngendwangu emnyama ukuze uqiniseke ukuthi awutholi luthuli. Uma wenza kanjalo, geza futhi. Khona-ke ungalungisa i-primer nomdwebo.
Ngakolunye uhlangothi, uma uthola ukuthi i-veranda yakho ivaliwe, unezinketho ezimbalwa: susa i-sealant ngamakhemikhali, ugaye phezulu ukuze uveze ukhonkolo obala noma ubuyekeze izinketho zakho. Ukucwecwa kwamakhemikhali nokugaya kuyinkinga ngempela futhi kuyisicefe, kodwa kulula ukushintshela kupende onamathela ngisho nakukhonkolo ovaliwe. I-Behr Porch & Patio Floor Paint ibonakala iwuhlobo lomkhiqizo engqondweni yakho, ngisho noma usebenzisa i-primer, ngeke inamathele kukhonkolo evaliwe. Kodwa-ke, upende waphansi we-epoxy we-Behr wengxenye engu-1 kanye negaraji limakwe njengokufanele ukumbozwa ngokuqondile ukhonkolo ovalwe ngaphambilini, inqobo nje uma uhlanza phansi, ufaka isihlabathi noma yiziphi izindawo ezicwebezelayo futhi ukhuhla noma isiphi isivalo esixebukayo. (Isivalo sikakhonkolo “esibonakala simanzi” sakha ifilimu engaphezulu ekwazi ukuxebuka, kuyilapho ukungena ku-sealant ngeke kushintshe ukubukeka futhi akusoze kwaxebuka.)
Kodwa ngaphambi kokuba uthembise ukudweba yonke i-veranda ngalokhu noma yimuphi umkhiqizo ofanayo, penda indawo encane futhi uqiniseke ukuthi unelisekile ngomphumela. Kuwebhusayithi ye-Behr, bangama-62% kuphela ababuyekezi abangama-52 abathi bangancoma lo mkhiqizo kubangani. Izilinganiso ezimaphakathi kuwebhusayithi ye-Home Depot zicishe zifane; phakathi kwababuyekezi abangaphezu kuka-840, cishe uhhafu walinika izinkanyezi ezinhlanu, okuyisilinganiso esiphakeme kakhulu, kuyilapho cishe ingxenye yesine yanikeza inkanyezi eyodwa kuphela. Iphansi kakhulu. Ngakho-ke, amathuba akho okwaneliswa ngokuphelele futhi ucindezeleke ngokuphelele angase abe ngu-2 kuya ku-1. Kodwa-ke, izikhalazo eziningi zihilela ukusetshenziswa komkhiqizo esitezi segaraji, amathayi emoto azofaka ingcindezi ekugcineni, ngakho-ke ungase ube nethuba elingcono lokujabula emphemeni.
Naphezu kwalokhu, kusenezinkinga eziningi ngokudweba ukhonkolo. Kungakhathaliseki ukuthi ukhetha yiphi isiphetho, noma ukuthi uqaphele kangakanani ezinyathelweni zokulungiselela, kusewukuhlakanipha ukudweba endaweni encane, ulinde isikhashana bese uqinisekisa ukuthi ukuqeda kunamathela. . Ukhonkolo ongapendiwe uhlale ubukeka kangcono kunokhonkolo onopende oxebukayo.
