I-plaster retarder iyisengezo esibalulekile ekufakweni kokukhonkolo, enikeza isikhathi esengeziwe sokusebenza, ukulawula okwandisiwe, kanye nokunciphisa imfucuza. Ngokunciphisa isikhathi sokubeka ukhonkolo, abahlehlisi benza abaplasta bakwazi ukuthola imiphumela engcono kanye nokusebenza kahle kokukhonkoloza, okugcine kube nesandla empumelelweni yemiklamo yokuplasta.
