Epoxy terrazzo rough grinding is done dry with vacuum systems to collect the grinding dust. In contrast, cement terrazzo is wet-ground so a grinding slurry is created. After the floor is rough ground until the metal or plastic divider strips are exposed and the aggregate is uniformly exposed, both systems are grouted.

High moisture can lead to mold and fungus. As grains reach maturity the moisture content diminishes. Storage of grain will allow flexibility to the farmer to use marketing and possibly receive season price increases. There is a cost incurred for storing grains, so the farmer must decide based on storage capacity and expected returns after storage.
