1. Kugira ngo icyumba gishyirwamo umwuka gikomeze gukora neza, umuvuduko w'umwuka ukwiye kugenzurwa mu rugero rwa (0.25 ~ 1) m/s hakurikijwe ingingo z'amategeko agenga umutekano w'umurimo n'ubuzima. Imyotsi isohoka mu cyumba gishyirwamo umwuka ni ingano nini y'umwuka, ingano y'umwuka uva mu mwuka ni nto cyane (ingano yayo iri hagati ya 10-3% ~ 2×10-'%). Byongeye kandi, imyotsi isohoka mu cyumba gishyirwamo umwuka irimo n'igice cy'irangi rikorwa no gutera umuti.
Ingano y'agace k'umukungugu (ibitonyanga by'ibihumyo bya lacquer) ni hafi μm (20 ~ 200) cyangwa irengaho, nta muyaga munini uguruka kure, kandi ugateza akaga rubanda hafi aho, ariko kandi ukaba imbogamizi mu gutunganya imyuka ihumanya, ibi bigomba kwitabwaho.
2. Akamaro k'umwuka wo mu cyumba cy'umwuka wumisha umwuka mu cyumba ni ugukora irangi riri mu irangi, kumisha cyangwa kumisha ku ngufu mbere yo kubikora, kugira ngo igice cy'umushongi muri filimi gihinduke neza kandi habeho firime nziza, muri rusange ni ukwagura inzira y'icyumba cy'irangi, muri iyi firime irimo umwuka wo mu mwuka gusa, kandi hafi ya yose nta n'umukungugu wo mu irangi urimo.
3. Imyotsi iva mu cyumba cyo kumisha Imyotsi iva mu cyumba cyo kumisha, harimo imyotsi iva mu buryo bwo gusiga amarangi n'uburyo bwo gusiga lisansi. Iya mbere irimo ikintu gisigaye mu gikoresho cyo gusiga kitava mu cyumba cyo kumisha no mu cyumba cyo kumisha, igice cy'ibintu bihinduka nka plasticizer cyangwa resin monomer, ibicuruzwa byo kubora ubushyuhe, ibicuruzwa byo gukora. Iya nyuma ikoreshwa nk'isoko y'ubushyuhe bw'imyotsi iva mu gutwika lisansi. Ibigizemo biratandukanye bitewe n'ibicanwa, nko gutwika amavuta menshi, birimo sulfure nyinshi mu ikorwa rya gazi ya sulfite, iyo ubushyuhe bw'itanura buri hasi, ihinduka ry'imikorere n'imicungire mibi, bitewe no gutwika kutuzuye n'umwotsi. Ikoreshwa rya lisansi ya lisansi, nubwo ikiguzi cya lisansi kiri hejuru kandi gazi iva mu gutwika ikaba isobanutse neza, hari ikiguzi gito cy'ibikoresho, kuyitaho byoroshye, n'inyungu nyinshi mu gukoresha ubushyuhe. Aho amashanyarazi n'umwuka bikoreshwa nk'isoko y'ubushyuhe mu cyumba cyo kumisha, imyuka iva mu buryo bwo kumisha lisansi ntibyitabwaho.
