Nws yog ntshaw kom siv lub ntsuas raws nraim qhov pom zoo los ntawm lub chaw muag khoom xim.
Lub qab nthab nrog plaster yog qhov yuav tsum tau yog qhov sib txawv ntawm qhov qab nthab yog 2-5 cm. Cov qhov cuab lub zog ua rau daim nplaum plev zoo dua. Rau ntawm 3 mus rau 3 xuab moos, koj tuaj yeem thov daim xim pleev, uas yog tsau rau ntawm PVA kua nplaum los yog tau txais ib daim phiaj nrog nplaum nplaum. Ntawm qhov sib txawv ntawm ntau tshaj 3 cm, nrog kev pabcuam tshwjxeeb, pobntseg lossis phuam, cov hlau kab yog "txhaj" rau lub qab nthab.
Kho kom haum nrog lub qab nthab nrog putty yog ua kom tshem tawm cov me me nyob hauv qhov chaw thiab muab lub qab nthab ua ib qho. Kev tshem tawm ntawm kab nrib pleb thiab chips yog nqa nrog kev pab pib ntawm pib, uas yog siv rau lub qab nthab los ntawm txheej tsis tshaj 2 hli. Sib tw ntawm lub qab nthab rau duab yuav tsum ua kom tiav los ntawm kev thov ib txheej ntawm kev ua tiav teg haujlwm. Qhov no yuav ua rau qhov chaw zoo kawg nkaus tus. Tom qab thov txhua txheej, nws yog ib qhov tsim nyog yuav tau muab cov qhov ntxaum kom qhuav kom qhuav. Txwv tsis pub, cov xim yuav tshwm sim ntawm qhov chaw.
Hauv cov rooj sib txawv qhov sib txawv li 5 cm, thiab qhov siab ntawm chav tsev tsis tso cai txhim kho cov ce, cov npuas dej yuav siv tau. Kev kho kom lub qab nthab nrog ua npuas dej ua kom tshem tawm qhov sib txawv ntawm qhov sib txawv thiab tib lub sij hawm tsis zoo heev "qis" lub qab nthab.
Mixtures rau puttying thiab plastering yog tsim los ntawm gypsum thiab cement. Rau chav nrog high humidity, xws li chav dej lossis chav ua noj, tsuas yog siv cov cement mixtures.
Cov kws tshaj lij pom zoo kom muag mixtures mus rau theem lub qab nthab ntawm ib lub khw. Qhov no yuav lav tau qhov "compatibility" ntawm cov ntaub ntawv. Txwv tsis pub, qhov saum npoo tej zaum yuav ua rau exfoliated los yog o. Tsis tas li ntawd, koj yuav tsum tau them sai sai rau ntawm lub khw muag khoom, qhov twg koj yuav qhov sib tov, ib qho kaw tsev kaw khoom.
