Mubvunzo: Ndine vharanda rekongiri rekare risina kumbopendwa.Ndichaipenda ne terrace latex pendi.Ini ndinoronga kuichenesa neTSP (Trisodium Phosphate) uyezve kushandisa kongiri yekubatanidza primer.Ini ndinofanira kunyora ndisati ndashandisa primer?
Mhinduro: Kuchenjera kungwarira pakuita matanho anodiwa ekugadzirira.Kuwana pendi yekunamatira kune kongiri kwakaoma zvakanyanya pane kunamatira pahuni.Chinhu chekupedzisira chaunoda kupemha pendi, kunyanya pamavharanda akararama pasina pendi mumakore ano.
Kana iyo pende isinganamati kune kongiri zvakanaka, dzimwe nguva nekuti unyoro hunopinda kuburikidza nekongiri kubva pasi.Kuti utarise, isa chidimbu chakakora chepurasitiki chakajeka (senge 3-inch square yakachekwa kubva mubhegi repurasitiki rinovharika) panzvimbo isina kupendwa.Kana madonhwe emvura akaonekwa zuva rinotevera, ungada kubva pavharanda sezvazviri.
Chimwe chikonzero chakakosha nei pendi dzimwe nguva isinganamati kune kongiri: iyo yepamusoro yakanyanyisa uye yakaoma.Mugadziri anowanzozora kongiri pavharanda nepauriri kuita jecha rakanaka kwazvo rakaputirwa negrout.Izvi zvinoita kuti pasi denser kupfuura kongiri mberi mune slab.Kana kongiri ichionekwa mumamiriro ekunze, iyo nzvimbo inopera nekufamba kwenguva, ndicho chikonzero iwe unogona kazhinji kuona jecha rakafumurwa uye kunyange matombo panzira dzekare dzekongiri uye maturu.Zvisinei, pavharanda, ruvara rwepamusoro runogona kunge rwakanyanya uye yunifomu sepainodururwa kongiri.Etching inzira yekuomesa pamusoro uye kuita kuti pendi iname zvirinani.
Asi etching zvigadzirwa zvinoshanda chete kana kongiri yakachena uye isina kuvharwa.Kana iyo kongiri yakapendwa nependi, unogona kuona nyore pendi, asi chisimbiso chinodzivirirawo pende kubva kunamira chingave chisingaoneki.Imwe nzira yekuyedza sealant ndeyekudira imwe mvura.Kana ikanyura mumvura, kongiri inoshama.Kana iyo ikaita puddle pamusoro uye inoramba iri pamusoro, inofungidzirwa kuti nzvimbo yacho yakavharwa.
Kana mvura ikanyura mumvura, isa ruoko rwako pamusoro pepamusoro.Kana magadzirirwo acho akafanana nepakati kusvika kune rough sandpaper (150 grit igwara rakanaka), iwe ungasada kupinza, kunyangwe hazvo isingazokuvadzwa.Kana iyo nzvimbo yakatsetseka, inofanira kuvharwa.
Nekudaro, danho rekushongedza rinodiwa mushure mekuchenesa kongiri.Zvinoenderana nehunyanzvi hwekubatsira vashandi veSavogran Co. (800-225-9872; savogran.com), iyo inogadzira zvigadzirwa zviviri izvi, TSP uye TSP dzimwe nzira dzakakodzerawo chinangwa ichi.Pondo yebhokisi reTSP hupfu inongodhura $3.96 paHome Depot, uye inogona kukwana, nekuti hafu yekapu yemarita maviri emvura inogona kuchenesa anenge 800 square feet.Kana ukashandisa high-pressure cleaner, quart yemvura TSP replacement cleaner, ine mutengo we$5.48, ichava nyore kushandisa uye inogona kuchenesa inenge 1,000 square feet.
Nezve etching, unowana akatevedzana ezvigadzirwa zvinovhiringa, zvinosanganisira standard hydrochloric acid uye zvigadzirwa zvakaita seKlean-Strip Green Muriatic Acid ($7.84 per galoni yeHome Depot) uye Klean-Strip Phosphoric Prep & Etch ($15.78 per galoni).Sekureva kwevashandi vekambani yekubatsira tekinoroji vakati iyo "girini" hydrochloric acid yaive yakadzikama uye yakanga isina kusimba zvekuisa kongiri yakatsetseka.Nekudaro, kana iwe uchida etch kongiri inonzwa zvishoma rough, iyi isarudzo yakanaka.Phosphoric acid inokodzera kongiri yakatsetseka kana yakaoma, asi haudi kubatsirwa kwayo kukuru, ndiko kuti, yakakodzera kongiri uye simbi ine ngura.
Kune chero etching chigadzirwa, zvakakosha kwazvo kutevedzera ese ekuchengetedza ekuchengetedza.Pfeka zvinofemesa kumeso kana hafu zvine mafirita asingagadzirisi acid, magirazi, magirovhosi asingaurayiwi nemakemikari anovhara maoko, uye bhutsu dzerabha.Shandisa gaba repurasitiki rekupfapfaidza kuisa chigadzirwa, uye shandisa mutsvairo usina simbi kana bhurasho rine mubato kuisa chigadzirwa kumusoro.A high-pressure cleaner ndiyo yakanakira kugezesa, asi unogona zvakare kushandisa hose.Verenga chinyorwa chakazara usati wavhura mudziyo.
Mushure mekucheka kongiri uye kuisiya yakaoma, pukuta nemaoko ako kana jira dema kuti uone kuti haina guruva.Kana ukadaro, sukurudza zvakare.Ipapo iwe unogona kugadzirira primer uye pendi.
Nekune rumwe rutivi, kana ukaona kuti vharanda rako rakavharwa, une zvakawanda zvingasarudzwa: bvisa chisimbiso nemakemikari, kukuya pamusoro kuti ufumure kongiri yakashama kana fungazve zvaungasarudza.Kemikari peeling uye kugaya zvinonetsa uye zvinofinha, asi zviri nyore kushandura pendi inonamira kunyangwe pane yakavharwa kongiri.Behr Porch & Patio Floor Paint inoita kunge rudzi rwechigadzirwa mupfungwa dzako, kunyangwe ukashandisa primer, haibatike kune yakavharwa kongiri.Nekudaro, Behr's 1-part epoxy kongiri uye pendi yepasi pegaraji inomakwa seyakakodzera kuvhara kongiri yakambovharwa, chero ukachenesa pasi, jecha chero nzvimbo dzinopenya uye nekukwenya chero chinosvuura sealant.(Iyo "yakanyorova kutaridzika" kongiri sealant inoumba firimu repamusoro rinogona kusvuuka, nepo kupinda mukati meiyo chisimbiso hakuzochinji chitarisiko uye kusambobvisa.)
Asi usati wavimbisa kupenda vharanda rose neizvi kana chero chigadzirwa chakafanana, penda nzvimbo duku uye iva nechokwadi chokuti unogutsikana nemugumisiro.Pawebhusaiti yeBehr, chete 62% yevaongorori makumi mashanu nevaviri vakati vaizokurudzira chigadzirwa ichi kushamwari.Avhareji zviyero pawebhusaiti yeHome Depot zvakangofanana;pakati pevanopfuura 840 vaongorori, inenge hafu yakapa nyeredzi shanu, iyo ndiyo yepamusoro-soro, nepo chikamu chechina chakachipa nyeredzi imwe chete.Ndiyo yakaderera.Nokudaro, mikana yako yekugutsikana zvachose uye kuora mwoyo zvachose inogona kuva 2 kusvika 1. Zvisinei, zvichemo zvakawanda zvinosanganisira kushandiswa kwechigadzirwa pagaraji regaraji, matairi emotokari achaisa kudzvinyirira pamagumo, saka iwe unogona kuva nemukana uri nani ndichifara paberere.
Pasinei neizvi, kuchine matambudziko akawanda nekupenda kongiri.Hazvina mhosva kuti ndeipi kupera kwaunosarudza, kana kuti wakangwarira sei mumatanho ekugadzirira, zvichiri kuchenjera kupenda panzvimbo duku, kumirira kwechinguva uye iva nechokwadi chokuti kupera kunonamatira..Kongiri isina pendi nguva dzose inotaridzika zviri nani pane kongiri ine peeling pendi.
