Cov txheej txheem tsim kho
- Kev kho av tiaj tiaj: xuab zeb kom huv, qhov chaw hauv paus yuav tsum qhuav, tiaj tus, tsis muaj lub nruas khoob, tsis muaj kev xuab zeb loj;
- Primer: ob-component raws li qhov ntau ntawm proportioning do (hluav taws xob tig 2-3 feeb), nrog rau dov lossis scraping kev tsim kho;
- Hauv cov tshuaj pleev xim: ob-feem sib xyaw raws li qhov ntau ntawm cov xuab zeb quartz tau teev tseg (kev sib hloov hluav taws xob 2-3 feeb), nrog rau kev siv scraper;
- Hauv cov xim pleev xim: ob-feem sib xyaw raws li qhov ntau ntawm kev sib xyaw (kev sib hloov hluav taws xob 2-3 feeb), nrog rau kev siv scraper;
- Txheej sab saum toj: cov xim thiab cov tshuaj kho raws li qhov ntau ntawm qhov sib piv (hluav taws xob tig 2-3 feeb), nrog rau txheej roller lossis tshuaj tsuag.
