Kusiyana pakati pa kunja kwa khoma putty ufa ndi mkati khoma putty ufa
1. Kusiyana kwakukulu pakati pa khoma lamkati lamkati ndi kunja kwa khoma la putty ndilosiyana. Putty yamkati yamkati imagwiritsa ntchito ufa wa Shuangfei (ufa waukulu woyera) monga zopangira zazikulu, kotero kuti madzi ake amakanizidwa ndi kuuma kwake kumakhala kosauka. Kunja kwa khoma putty kumagwiritsa ntchito simenti yoyera ngati chinthu chachikulu, kotero kuti madzi ake osakanizidwa ndi kuuma kwake kumakhala kolimba kwambiri.
2. Palibe kusiyana kwakukulu mu makulidwe (particles) a putty pakhoma lamkati ndi putty pakhoma lakunja, ndipo n'zovuta kusiyanitsa ndi dzanja ndi kukhudza.
3. Palibe kusiyana kwakukulu pakati pa khoma lamkati lamkati ndi putty yakunja ya khoma potengera chitetezo cha chilengedwe, chifukwa momwe chilengedwe chimagwirira ntchito ndizofanana.
4. Kunja kwa khoma putty kumakhala ndi mphamvu zambiri. Sili bwino ngati putty wamkati wamkati akamakanda pakhoma, ndipo sikophweka kupukuta mukaumitsa.
5. Zopangira zazikulu zamkati khoma putty ndi ufa woyera. Ziribe kanthu momwe zimapangidwira, mphamvu ya ufa woyera imakhala yochepa kwambiri mutatha kuyanika. Ikhoza kukanda ndi misomali, ndipo idzafewetsanso pambuyo pokumana ndi madzi.
6. Mphamvu ya simenti yoyera imakhala yochuluka kwambiri pambuyo pa hydration ndi kulimbitsa, ngakhale ndi nyundo yaying'ono, palibe chotsatira, ndipo sichidzasungunuka kapena kufewetsa kachiwiri pambuyo poyang'aniridwa ndi madzi.
7. Kusiyana pakati pa putty pakhoma lamkati ndi putty pa khoma lakunja ndilokuti putty pa khoma lakunja ali ndi mlingo wina wa kukana madzi ndipo saopa mvula. Ndi mafuta opaka mafuta ndipo amatha kugwiritsidwa ntchito pamakoma amkati ndi akunja. Khoma lamkati lamkati silikhala ndi madzi ndipo silingagwiritsidwe ntchito pamakoma akunja.
