5. Seretse sa ka ntle sa lerako Setlolo sa cellulose ether sehloohong sena se lebisa tlhokomelo ho tlamahano le ho eketsa matla, ho etsa hore seretse se be bonolo ho se sebelisa le ho ntlafatsa katleho ea mosebetsi. Anti-sag effect, ts'ebetso e phahameng ea ho boloka metsi e ka lelefatsa nako ea tšebeletso ea seretse, ea ntlafatsa ho hanyetsa ho khutsufatsa le ho senya, ho ntlafatsa boleng ba holim'a metsi le ho eketsa matla a tlamo.
6. Li-ceramics tsa mahe a linotši Ka lirafshoa tse ncha tsa mahe a linotši, lihlahisoa li na le boreleli, ho boloka metsi le matla.
7. Sealant, suture Ho eketsoa ha cellulose ether ho etsa hore e be le sekhomaretsi se setle ka ho fetisisa, tekanyo e fokolang ea ho fokotseha le ho hanyetsa ho apara ho phahameng, le ho sireletsa boitsebiso bo ka sehloohong ho senya mochine, ho thibela tšusumetso ea ho koloba mohahong oohle.
8. Ho itšehla thajana Ho khomarela ho tsitsitseng ha cellulose ether ho etsa bonnete ba hore ho na le mokelikeli o babatsehang le bokhoni ba ho ikemela, 'me tekanyo ea ho boloka metsi e sebetsang e nolofalletsa ho beha kapele, ho fokotsa ho phunyeha le ho khutsufatsa.
9. Ho haha seretse sa plastering seretse Ho boloka metsi a mangata ho etsa hore samente e be le metsi ka ho feletseng, e eketsa haholo matla a tlamahano, 'me ka nako e ts'oanang e eketsa matla a ho tsitsa le ho kuta, e leng ho ntlafatsang haholo phello ea kaho le katleho ea mosebetsi.
10. Sekhomaretsi sa lithaele Ho boloka metsi a phahameng ha ho hloke ho kenngoa pele kapa ho kolobisoa ha lithaele le lihlopha tsa motheo, tse ntlafatsang haholo matla a tlamahano, nako e telele ea kaho ea slurry, kaho e ntle le e ts'oanang, kaho e loketseng, le anti-migration e babatsehang.
