4. Ceev faj
♦ Ua ntej siv tus kheej-leveling cement,xyuas kom cov chav dej hauv pem teb qhuav, tiaj tus thiab ruaj khov kom tsis txhob muaj slurry los ntawm adhering yooj yim los yog ua rau hollowing.
Self-leveling cement muaj lub zog siab thiab hnav tsis kam, tab sis rau cov chaw thauj khoom hnyav lossis thaj chaw muaj kev sib txhuam tsis tu ncua, nws raug nquahu kom ntxiv dag zog lossis xaiv cov khoom hnav-tiv taus dua.
♦ Thaum sib tov tus kheej-leveling cement,cov khoom sib faib thiab sib tov lub sij hawm yuav tsum nruj me ntsis tswj raws li cov lus qhia kom ruaj khov slurry zoo.
♦ Thaum khawb,kev saib xyuas yuav tsum tau them rau kev tswj lub zog thiab kev taw qhia ntawm scraper kom tsis txhob khawb los yog cov cim. Kev tsis sib xws hauv zos lossis qhov tsis xws luag tuaj yeem kho.
