2. Txhawm rau kom txuag tau cov nqi, cov tog neeg cuam tshuam nrhiav cov nqi qis, thiab cov sealant thib ob rau cov iav rwb thaiv tsev siv cov sealant tsis yog silicone xws li polysulfide thiab silicone construction sealants;

3. Qee cov neeg ua haujlwm tsim kho tsis yog cov kws tshaj lij thiab tsis ua raws li txoj cai, ua rau muaj teeb meem ntawm qhov dav ntawm cov tshuaj pleev thaiv iav insulating.

Cov kev ceev faj rau kev xaiv cov sealant thib ob

Cov tshuaj nplaum thib ob rau cov iav rwb thaiv tsev muaj feem cuam tshuam loj heev rau qhov zoo thiab lub neej ua haujlwm ntawm cov iav rwb thaiv tsev. Cov tshuaj nplaum rau cov iav rwb thaiv tsev muaj feem cuam tshuam ncaj qha rau kev nyab xeeb ntawm phab ntsa ntaub thaiv. Yog li ntawd, peb yuav tsum tsis txhob tsuas yog xaiv cov khoom zoo xwb, tab sis kuj xaiv cov khoom zoo.

Ua ntej, nws ua raws li cov qauv thiab raws li qhov xav tau. Qhov thib ob, tsis txhob siv cov roj sealant. Thaum kawg, xaiv lub npe nrov xws li junbond.
