Ma geji ofananira a granite ndi zida zoyezera mwatsatanetsatane, ndipo kukhulupirika kwa kutsetsereka kwawo kumakhudza mwachindunji kuyeza kwake. Kuyeretsa kapena kuugwira molakwika kungayambitse kukanda, dzimbiri, kapena kusintha kosawoneka bwino kwa mwala, ndikusokoneza kulondola kwake. Kusunga zidazi kumafuna kusamala kwambiri ndi njira zoyeretsera, zida, ndi chilengedwe.
Tisanayambe kuyeretsa, ndikofunikira kukonza malo otetezedwa, opanda fumbi. Choyezeracho chiyenera kuyikidwa pamalo owuma, odziyimira pawokha kuti tinthu tating'onoting'ono ta mpweya, zometa zachitsulo, kapena zotsalira zamafuta zisaipitse pamwamba. Zida zonse zoyeretsera, kuphatikizapo nsalu zofewa, masiponji, ndi maburashi, ziyenera kutsukidwa bwino ndi kuyang'aniridwa kuti muchotse ulusi wotayirira kapena tinthu tating'ono tomwe titha kukanda granite. Kumvetsetsa mtundu wa madontho - kaya ndi mafuta, acidic, kapena pigment - kumathandizanso kudziwa njira yabwino kwambiri yoyeretsera.
Kusankha choyeretsera choyenera nkofunikanso chimodzimodzi. Granite imakhudzidwa ndi zidulo ndi ma alkaline amphamvu, motero zotsukira zopanda ndale zomwe zili ndi pH pakati pa 6 ndi 8 ziyenera kugwiritsidwa ntchito. Zoyeretsa m'nyumba zankhanza, monga zomwe zili ndi sodium hydroxide, ziyenera kupewedwa, chifukwa zimatha kuwononga pamwamba pamwala. Pamadontho amakani, zotsukira mwala zapadera zitha kugwiritsidwa ntchito mukayesa malo ang'onoang'ono, osawoneka bwino kwa maola 24 kuti muwonetsetse kuti palibe kusinthika kapena kutayika kwa gloss. Zinthu zoyeretsera zosiyanasiyana siziyenera kusakanikirana, chifukwa zochita za mankhwala zimatha kutulutsa mpweya woipa kapena kuchepetsa kuyeretsa.
Pakuyeretsa, kusunga njira yopukutira mosasinthasintha komanso kupanikizika pang'ono ndikofunikira. Nthawi zonse pukutani mbali imodzi yofanana ndi burashi kapena nsalu kuti mupewe kukwapula. Maburashi ofewa amayenera kugwiritsidwa ntchito m'mphepete kuteteza ma chamfers. Mukamaliza kuyeretsa, yambani bwino ndi madzi oyeretsedwa kapena oyeretsedwa kuti muteteze mchere ndikuwumitsa pogwiritsa ntchito nsalu zopanda lint kapena mpweya wabwino wachilengedwe. Kutentha kapena kuwala kwa dzuwa kuyenera kupewedwa, chifukwa kusintha kwadzidzidzi kutentha kungayambitse kusweka.
Chisamaliro chapadera chiyenera kuperekedwa ku madontho adzidzidzi komanso kukonza nthawi yayitali. Zinthu za acidic, monga madzi a zipatso kapena viniga, ziyenera kutsukidwa nthawi yomweyo ndi kuchepetsedwa ndi ammonia wosungunuka mutavala magolovesi otetezera. Zing'onozing'ono zachitsulo zimatha kupukutidwa mofatsa ndi ufa wopukuta mwala ndikumveka, koma zowonongeka zakuya ziyenera kuthandizidwa ndi akatswiri. Madontho osalekeza omwe alowa pamwamba pa granite amafunikira kuyeretsa mwapadera ndi chithandizo cha crystallization kuti abwezeretse kusalala ndi gloss.
Kukonzekera kosalekeza ndikofunikira kuti muwonetsetse kulondola kwanthawi yayitali. Kupaka chosindikizira cholowera miyezi isanu ndi umodzi iliyonse kumapanga chotchinga chotchinga madontho, bola ngati pamwamba pauma ndipo chosindikiziracho chilowetsedwa mofanana. Kusungirako koyenera ndikofunikanso; zoyezera ziyenera kukhala mopingasa pa mphasa mphira kapena zogwiriziza matabwa, kupewa kukhudzana mwachindunji ndi zitsulo kapena zolimba, ndi olamulira kutentha kusinthasintha mkati ± 5 ℃ ndi chinyezi pansi 60%. Kuwongolera kwakanthawi pogwiritsa ntchito ma laser interferometers kapena magawo amagetsi ndikofunikira kuti mutsimikizire kuti miyeso yoyezera imasungidwa. Kupatuka kulikonse komwe kwapezeka kuyenera kuyimitsidwa nthawi yomweyo kugwiritsa ntchito ndikukonzanso akatswiri.
Mwa kuphatikiza kuyeretsa mosamala, kugwiritsa ntchito moyenera zinthu zotetezedwa ndi mwala, kusamalira moyenera, komanso kukonza nthawi zonse, moyo wautali komanso kulondola kwa geji zofananira za granite zitha kusungidwa bwino. Pazovuta zovuta zoyeretsa kapena chisamaliro chapadera, kukaonana ndi akatswiri okonza miyala kumalimbikitsidwa kwambiri kuti tipewe kuwonongeka kosasinthika ndikuwonetsetsa kuti miyeso ikupitilirabe.
