Txawm hais tias ua tau zoo tshaj plaws ntawm cov uas ua tiav cov pob zeb ua ke, qee zaum cov khoom kawg muaj qhov tsis zoo tseem ceeb. Txawm tias ntaub pua plag tso rau ntawm lub ncoo lossis cov yas yas tsis tuaj yeem npog txhua qhov tsis raug, yog li kev kho slab yog tus tswv tsev xaiv zoo tshaj los daws qhov teeb meem.
cov kauj ruam
Kauj Ruam 1. Txiav txim siab txog qhov teeb meem
Cov duab piv txwv hauv kab lus no qhia txog kev kho qhov twg cov nplais txhawb nqa tau ze dhau rau saum npoo av, thiab pob zeb tawg. Lwm yam teeb meem tuaj yeem suav nrog cov hauv qab no.
- Grooves los yog pob tawm ntawm cov neeg ua tiav.
- Kev nthuav dav los yog kev cog lus tawg.
- Cov khib nyiab zoo li cov ntoo ntab tawm ntawm lub pob zeb thaum nws tseem yas (ntub).
- Kev puas tsuaj los ntawm cov khoom hnyav ntog rau ntawm cov nplais ua ntej nws qhuav.
Kauj Ruam 2. Siv tus pas ntsuas los txiav txim qhov ntev thiab dav ntawm thaj chaw yuav raug kho yog qhov xwm txheej tsis tau teeb tsa
Qhov no tuaj yeem suav nrog pob, dips lossis roob. Cov cheeb tsam me me ntawm qhov tsis sib xws saum npoo av tuaj yeem zais nrog cov qib sib xyaw, ntau dua li chipping thiab hloov cov pob zeb.
Kauj Ruam 3. Txheeb cov pob zeb ua kom tshem tawm cov khoom siv uas tau tsa, thiab tsim kom muaj qhov chaw roughened los kho cov cement sib tov

Sib tov cov khoom xyaw qhuav ua ntej, siv qhov sib piv ntawm 1 feem Portland MAAs (Hom I lossis II) mus rau 2 1/2 qhov chaw huv masonry xuab zeb.
Kauj Ruam 6. Ntxiv cov kua polymerized los yog cov kua ua kua los rau cov xuab zeb qhuav/cov cement sib tov, siv kom txaus kom ntub cov khoom thiab nqa nws mus rau yas yas sib xws
Nco ntsoov tias qee tus neeg sawv cev sib koom ua ke tau thov ncaj qha rau thaj chaw kom tau ua thaj, xws li kua nplaum, yog li ua raws cov lus qhia ntawm cov khw tsim daim ntawv lo.
Kauj Ruam 7. Ntub qhov chaw uas yuav tsum muab cov kua nplaum tov nrog cov dej huv, huv
Tsis txhob dej nyab hauv cheeb tsam, tab sis xyuas kom txhua qhov chaw tau ntub dej kom pab ua kom cov cement sib tov tshiab ntxiv nrog rau tiv thaiv qhov sib xyaw kom qhuav sai sai. Cov chaw qhuav tsuas yog nqus cov dej noo tawm ntawm cov cement sib tov nrawm heev, thiab nws yuav ua rau nws tawg.

Kauj Ruam 9. Qib cov av ntub dej ntub nrog cov spatula, ua kom nws siab dua me ntsis ntawm cov ntug uas nyob ib sab, kom tso rau qhov ua kom dej ntws thiab nqaim
Cia nws qhuav thiab tawv rau ib teev, qhov nruab nrab, nyob ntawm qhov av thiab qhov kub.
Kauj Ruam 10. Khaws thaj tsam nrog tus phuam da dej thaum cov khoom ua kom tawv
Qhov no yuav ua rau theem thiab ua kom du thiab ua rau cov cement slurry nce mus rau saum npoo. Loj heev, thaj chaw sib sib zog nqus tuaj yeem muab pov nrog cov tshuaj magnesium kom nqa ntau cov cement slurry tuaj. Cov tshuaj txhuam no yog cov khoom siv uas tsim cov nplaim ntawm cov nplais ua tiav.
Kauj Ruam 11. Muab thaj tsam li ib teev lossis ob teev rau nws kom sib haum, lossis ua kom tawv tawv, tom qab ntawd ua kom tiav los ntawm spatulating

Kauj Ruam 12. Ntxuav cov cuab yeej, thiab tshem tawm cov khoom siv ntau dhau
Lub tswv yim
- Rau qhov me me heev, koj tuaj yeem yuav cov tshuaj ntxiv dag zog rau polymer lossis cov khoom qhuav ua ntej sib xyaw.
- Tiv thaiv kev kho los ntawm tshav ntuj ncaj qha. Ib lub thawv ntawv thawv yuav ua haujlwm.
