pali mitundu yambiri ya zosungunulira zomwe zimapezeka posungunula ethyl cellulose, iliyonse ili ndi ubwino ndi malire ake. Kusankhidwa kwa zosungunulira kumatengera zinthu zosiyanasiyana, kuphatikiza zofunika kusungunuka, momwe zinthu zimagwirira ntchito, malingaliro achitetezo, komanso nkhawa zachilengedwe. Ndikofunika kufufuza mosamala zinthuzi ndikusankha chosungunulira choyenera kwambiri pa ntchito iliyonse kuti tipeze zotsatira zabwino pamene tikuonetsetsa kuti chitetezo ndi kukhazikika kwa chilengedwe.
