Mphamvu yabwino yomangirira ya utomoni wa polima wokha imathandizira kumamatira kwazinthu zamatope a simenti ku magawo, makamaka simenti, chomangira chamkati, nkhuni, ulusi, PVC. Kupititsa patsogolo kukhazikika kwa chisanu kumalepheretsa kusweka kwa zinthu, komansoredispersible latex ufaili ndi mphamvu ya pulasitiki ya utomoni wake wa thermoplastic, womwe ungagonjetse kuwonongeka kwa kukulitsa ndi kutsika kwa kutentha komwe kumachitika chifukwa cha kusintha kwa kutentha kwa zinthu zamatope a simenti. Kugonjetsa mikhalidwe ya shrinkage yayikulu yowuma komanso kusweka kosavuta kwa matope oyera a simenti kungapangitse kuti zinthuzo zikhale zosinthika, potero kumapangitsa kukhazikika kwazinthuzo kwanthawi yayitali. Limbikitsani kupindika ndi kukana kwamphamvu. Mu chimango okhwima opangidwa ndi hydration wa simenti matope, nembanemba wa polima ndi zotanuka ndi kusinthasintha, kusewera ntchito yofanana monga zosunthika olowa pakati simenti matope particles. Imatha kupirira katundu wopindika kwambiri, kuchepetsa kupsinjika, ndikuwongolera kulimba komanso kupindika.
