Kutsika mtengo kwa matope opangidwa ndi polima kumapangitsa kukhala njira yabwino yopangira ntchito zosiyanasiyana zomanga.
Kuphatikizika kwa ma polima otayika mu ufa wa ER m'mapangidwe amatope kumapereka maubwino angapo omwe amakhudza magwiridwe antchito, kulimba komanso mtundu wonse wa zida zomangira. Kuchokera kumamatira bwino ndi kusinthasintha mpaka kupititsa patsogolo kupirira kwa nyengo ndi kuchepetsa kuchepa, ubwino umenewu umapangitsa matope opangidwa ndi polima kukhala chisankho chofunika kwambiri pa ntchito zosiyanasiyana zomangamanga. Pomwe ukadaulo ukupitilirabe patsogolo, zopanga zatsopano zopangira ufa wa latex zitha kuthandizira kupitilizabe kupanga zida zamatope kuti zipereke njira zokhazikika komanso zogwira ntchito kwambiri pazomanga.
