Yuav kom plaster phab ntsa nrog cov khoom zoo, nws yog ib qho tsim nyog kom ua tiav qhov feem ntau qhov chaw. Txhawm rau pab txhawb txoj haujlwm, lawv siv thev naus laus zis ntawm qib phab ntsa siv cov lus qhia tshwj xeeb, uas yog hu ua beacons.
Lighthouses yog ua los ntawm hlau, yas, ua koj tus kheej los ntawm gypsum los yog cement mortar. Kev siv cov lus qhia npaj ua kom nrawm nrawm rau cov txheej txheem, uas yuav luag tsis cuam tshuam rau tus nqi ntawm kev ua tiav: lawv pheej yig, txhim kho sai dua li cov khoom tsim hauv tsev. Tsis tas li ntawd, lawv qhov zoo dua yog tias cov tshuaj uas tau poob rau ntawm cov hlau lossis yas beacon yog yooj yim los ntxuav, tab sis nrog gypsum los yog cement nws tsis yooj yim.
Yog li, peb yuav lighthouses ntawm qhov loj (qhov tuab ntawm txheej plaster nyob ntawm qhov siab ntawm lub teeb), txiav rau hauv daim ntawm qhov loj me (tus qauv ntev yog 3 m), siv cov txiab hlau zoo tib yam..
Yuav ua li cas rau nruab beacons ntawm mortar
Ntawm phab ntsa nrog cov kav dej lossis cov xov coated peb siv cov kab ntsug hauv ntau qhov chaw ntawm phab ntsa. Ntawm txhua tusntawm no, peb npaj tsawg kawg tsib daim ntawm mortar, uas peb nruab beacons rau theem phab ntsa. Txhua daim ntawv qhia raug nias kom cov tshuaj hla dhau lub qhov rau cov fasteners. Tom qab ntawd, cov beacons, siv lub tsev theem, yog vertically.
Tom qab lub beacons rau theem phab ntsa ntawm cov ces kaum raug teeb tsa, ob txoj hlua raug rub ntawm lawv los ntawm saum toj thiab hauv qab, uas tsim lub dav hlau ntawm lub neej yav tom ntej plaster. Tom ntej no yog lub installation ntawm cov lus qhia nruab nrab. Qhov kev ncua deb ntawm lawv yog txiav txim los ntawm qhov loj ntawm txoj cai uas yuav siv tau thaum plastering. Yog hais tias txoj cai ntev yog 2 meters, ces cov kauj ruam uas lub beacons ntsia rau theem phab ntsa yog 1.7-1.9 m. qaum.
Npaj mortar thiab plastering
Txhim kho cov phab ntsa hauv qab lub teeb pom kev cuam tshuam nrog kev siv tshuaj mortar rau plastering. Kev sib tov qhuav yog feem ntau siv, uas feem ntau yog ntxiv rau dej. Lawv yuav tsum tau npaj rau kev siv, nruj me ntsis raws li cov lus qhia uas txuas rau txhua qhov sib xyaw.
txheej txheem plastering nws tus kheej tau muab faib ua peb theem:
- Splatter. Ib qho kua dej ntau dua yog siv, uas ntxiv me ntsis dej ntxiv rau cov tshuaj tseem ceeb. Tom qab ntawd nws yog txau rau ntawm phab ntsa nrog ib txheej nyias (tsis pub ntau tshaj 2-3 hli). Nws tsis yog qhov tsim nyog los ntsuas cov txheej txheem no (yog tias nws qhov siab tshaj plaws thickness tsis tshaj qhov siab ntawm beacons).
-
phab ntsa sib dhoslos ntawm lighthouses nqi Zaj. Cov tshuaj yog ua raws li cov lus qhia, ib txheej tuab yog thov. Hauv qhov sib txawv ntawm cov beacons, ib qho kev daws teeb meem yog nteg, uas yog leveled los ntawm hauv qab mus rau txoj cai. Nws yog rub, siv beacons rau theem phab ntsa raws li kev txhawb nqa. Cov tshuaj ntau dhau raug tshem tawm ntawm lub cuab yeej nrog lub spatula thiab xa mus rau lub thoob rau kev siv tom qab. Nws tsis tuaj yeem ua tiav qhov zoo tshaj plaws nrog thawj qhov dhau los, yog li ntawd, siv lub spatula, qhov khoob thiab cov plhaub tau ntim nrog tshuaj khib, tom qab ntawd lawv tau rov qab nrog txoj cai.
- Tiav txheej lossis smoothing. Ib qho me me ntawm plaster yuav tsum tau diluted rau lub xeev ntawm qaub cream. Qhov no muaj pes tsawg leeg yog siv rau cov tseem ntub plaster (nws yuav tsum siv sij hawm 40-60 feeb tom qab nws daim ntawv thov) thiab rubbed nrog ib tug stainless hlau trowel. Yog li ntawd, qhov saum npoo yuav tsum du thiab glossy.
Txhua txheej ntawm plaster tsuas yog siv thaum yav dhau los qhuav (tshwj tsis yog smoothing). Tsis tas li ntawd, nws yog ntshaw kom npog txhua txheej nrog primer kom zoo adhesion (adhesion). Lub primer kuj yuav tsum tau qhuav. Qhov no yog txheej txheem ntev. Tab sis tsis muaj dab tsi nyuab heev nyob rau hauv nws, tab sis yog tias koj ntiav builders, nws yuav tsis pheej yig. Aligning cov phab ntsa nrog lighthouses (tus nqi yog xam rau ib square meter) tus nqi kwv yees li tus nqi uas mus rau kev yuav khoom. Yog li txiav txim siab: txawm them nyiaj zoo, lossis ua koj tus kheej.
