Mudzidzisi mumwe nomumwe anoda kuti imba yake ive yakanaka uye inofadza. Uye nokuda kweizvi hazvina kukwana kungoisunga. Uye pano, mavara akasiyana-siyana emitambo, anonzi mazhenje emapuranga okuchera kunze kwemabasa, anogona kuuya kununura.
Izvi zvinonongedza kuchengetedza uye zvakanyanya kuwedzera zvakakosha zvemukati. Pamusana pekuti pepa haifaniri kuvhara maperes muhutanda rakasara, haitadzi kudzivirira mvura. Mukuwedzera, kupfeka kupendeka kunodzivirira masvingo kubva pamigumisiro inokuvadza yemvura, fungus uye fungus. Mifananidzo yakawanda inowanikwa muhutano hwavo hwakasiyana-siyana, iyo inodzivisa kupisa kwekupfeka kwakadaro muzuva. Yakakwirira-yekunze yepende pepa haigoni kuve yakasvibiswa uye yakasvibiswa.
Zvose zvipfeko zvinoparadzaniswa zvinoshandiswa mumvura-kusunuka uye organo-soluble. Mvura yakasvibiswa, zvakare, yakakamurwa kuva mvura-emulsion (latex) uye mineral. Zvichienderana ne-binder, mvura-kuparadzanisa mapepa ndiyo vinyl, acrylic uye silicone. Chidimbu chinoreva simenti, silicate uye marimu emicheka, umo anosunga mumiririri portland samende, girasi remvura uye hydrated lime, maererano.
Nzira yekusarudza pepi yepadhesi padipi?
Kugadzira chimiro chakanaka uye chakasimba, zvakakosha kusarudza pepa yakakodzera. Paunosarudza kupfeka ruvara rwechigadziro, iwe unofanirwa kubhadhara kune unogadzira: bvunza mhinduro kune mumwe munhu akagadzira uye usarudze zvakakosha, iwe unofunga. Ngwarira zuva rokupera kwepende: usatenga chigadzirwa chakapera, chinogona kuipa zvakanyanya chigumisiro chekupedzisira.
Parazi yemafaini inoumbwa nezvikamu zvakasiyana-siyana zvakakosha: iyo pigment inobvisa ruvara rwepende, zvakasiyana-siyana zvinosungirirwa, nemhaka iyo iyo pende inosungirirwa zvakasimba kune pevara. Mukuwedzera, kuumbwa kwemapuranga kunosanganisira zvakasiyana-siyana zvinoshandiswa: plasticizers, kuoma accelerators, nezvimwewo.
Paunenge uchitenga zvidzitiro zvepende, unofanirwa kuverenga mirayiridzo pahutanda. Iyo yakanakisisa inowanikwa pamapuranga yakasimba, inopfeka kusagadzikana uye yakavimbika mukushanda. Iyi nyaya inofanirwa kunge iine hunyoro-uchapupu uye nemoto usingadziviri.
Chisarudzo chakanaka chepende yefaçade inoshandiswa pamapuranga ndeyezvinhu zvinomiririra munguva yechando inotonhorera nemhepo, chando kana mvura, uye muzhizha - kuwedzera kwenguva yakawanda yekupisa kwemhepo nemhepo inotakura gorova neguruva. Muchiitiko ichi, mugadziri anofanira kuratidza pahuturo hwekuti pende yakadaro inenge ichinaya mvura.
Utsi hwepende hunofanira kunge huripo kuitira kuti ruvara runyoro rufemedze. Uye zvinoenderana nemhando yebinder iyo inoshandiswa mu pende. Uyezve, chidimbu chepadhesi chinofanira kuva nehupamhi hwekubatanidza, kureva kuti, "zvakanamatira" zvachose kune pombi, pasina kuumba kunyema uye kuonekwa kwekupfeka.
Chiratidzo chinonyanya kukosha pakusarudzwa kwepadheti yependi ndeyekuyera kwekudzivirira kwayo: iyo yakakwirira iyi index, iyo inoramba ichidzivirira chiedza chezuva. Kuvhara chiganda nemapende akadaro kunobatsira kwenguva refu kuchengetedza kuonekwa kwakanaka uye kwakanaka kwechivako chechivako.
