1.Rake pa pulasitala yowonongeka ndi scraper ya utoto.Osagwiritsa ntchito chida kukwapula - ingojambulani pazomwe zawonongeka kuti muchotse zinthu zotayirira, zomwe ziyenera kugwera zokha.
2.Unroll mokwanira kudzimatirafiberglass maunatepi kuphimba mng'alu, Ngati mng'aluyo apindika, dulani kachidutswa kosiyana pa mwendo uliwonse wa mkhotolo - musayese kutsata kapindika pomanga chidutswa chimodzi cha tepi.Dulani tepiyo ngati mukufunikira ndi lumo ndikuyiyika pakhoma, ndikupsompsonana ngati pakufunika kuti muphimbe ming'alu.
3.Kuphimba tepi ndi pulasitala kapena drywall, Yang'anani chidebecho - ngati mumagwiritsa ntchito pulasitala - kuti mudziwe ngati muyenera kunyowetsa khoma musanagwiritse ntchito.Ngati malangizo akusonyeza kuti muyenera kunyowetsa khoma, chitani ndi siponji woviikidwa m'madzi.
4.Pakani chinsalu chimodzi cha pulasitala kapena cholumikizira cholumikizira pa tepi.Ngati mumagwiritsa ntchito ophatikizana, tambani ndi mpeni wowuma wa masentimita 6 ndikupukuta pamwamba kuti muphwanye.Ngati mugwiritsa ntchito pulasitala, ikani ndi pulasitala trowel, kuyala pamwamba pa tepi ndi nthenga m'mphepete mwa khoma lozungulira momwe mungathere.
5.Pakani malaya ena ophatikizana pambuyo pouma choyamba, pogwiritsa ntchito mpeni wa 8-inch.Yang'anani ndikuchotsa chowonjezeracho, ndikuyika m'mphepete mwake pakhoma.Ngati mukugwiritsa ntchito pulasitala, ikani wosanjikiza wopyapyala pamwamba pa yapitayo ikauma kuti mudzaze mabowo ndi voids.
6.Ikani malaya amodzi kapena awiri ophatikizana, pogwiritsa ntchito mpeni wa 10- kapena 12-inch.Pewani m'mphepete mwa chovala chilichonse mosamala kuti muwapange nthenga pakhoma ndikupanga kukonza kusawoneka.Ngati mukukonza ndi pulasitala, simukuyenera kuyikanso chinsalu chachiwiri chikauma.
7.Sand kukonza mopepuka ndi siponji mchenga kamodzi pulasitala kapena olowa pawiri wakhazikika.Yambani chophatikizana kapena pulasitala ndi polyvinyl acetate primer musanayambe kujambula khoma.
