Kev ua kom tiav ntawm cov nplaum nplaum no feem ntau yog P 800. Sab hauv cov ces kaum lossis cov khoom siv kho kom zoo nkauj tuaj yeem ua rau cov ntaub nplaum abrasive. Nws gradation mus ntawm R 220 mus rau qhov siab tshaj plaws tso cai R 280.
- Hauv qhov no, koj tsis tuaj yeem ua yam tsis muaj rab phom tsuag. Cov xim yuav tsum tau txau rau hauv ib txheej nyias. Yog hais tias koj pleev xim rau chav ua noj facade nrog txhuam, nws yog ib qho nyuaj rau ua tiav ib tug du nto. Cov phom rau xim tso cai rau siv cov xim sib npaug ntawm txhua qhov chaw. Qhov zoo ntawm cov cuab yeej no kuj yog tias nws tuaj yeem sau nrog primer. Hauv qhov no, kev ua haujlwm priming yuav tsis siv sijhawm ntau. Paub qhov txawv ntawm cov phom phom hluav taws xob thiab pneumatic. Cov hluav taws xob xav tau lub qhov hluav taws xob kom ncav cuag, thaum cov pneumatic xav tau lub tshuab ua haujlwm. Nws yog qhov zoo dua los yuav ib rab phom uas nws txoj kab uas hla tsis tshaj 1.3 millimeters. Tom qab ntawd cov xim pleev xim zoo dua thiab nteg tsis muaj qhov tsis xws luag.
- Tsis txhob hnov qab lub degreaser. Nws yuav xav tau ntawm thawj theem ntawm kev ua haujlwm. Cov kauj ruam degreasing saum npoo yuav tsum tsis txhob hla. Yog tias koj tsis siv lub cuab yeej raws sijhawm, yog li ntawd, cov teeb meem yuav tshwm sim uas yuav ua rau lub ntsej muag tsis zoo. Yuav tsum rov-repaint tag nrho façade. Tsis yog txhua tus paub tias kev ua haujlwm nrog ntoo, nrog rau MDF, yuav tsum muaj qhov tshwj xeeb degreaser. Nws yuav tsum muaj cov organic hnyav.

Nws gradation yuav tsum yog los ntawm P 220 mus rau P 280.
Yog tias lub façade ua los ntawm MDF raug xaiv rau kev ua haujlwm, feem ntau nws yuav raug them nrog cov yeeb yaj kiab tshwj xeeb. Nws yuav tsum tau muab tshem tawm tag nrho thiab tsuas yog tom qab qhov chaw tau ntxuav tag, pib ua haujlwm nrog cov ntawv xuab zeb.
Yuav ua li cas thiaj ua tiav?
Technology rau painting rooj tog facades tsis tiav yam tsis muaj priming saum npoo. Ua ntej koj yuav tsum degrease lub "ua hauj lwm pem hauv ntej". Tom qab ntawd, tsis txhob kov qhov chaw ntawm cov khoom.
Priming tuaj yeem muab faib ua ob peb theem:
- Qhov saum npoo tau kho nrog cov primer tshwj xeeb. Cov primer thawj zaug npog qhov kawg ntawm cov khoom, ces lub dav hlau nruab nrab yog ua tiav. Nws yog qhov zoo tshaj rau prime nrog ob txheej.
