The 8 frame inner cover is primarily used for ventilation of the hive. The inner cover also acts as a calming mechanism to the colony of bees when the telescopic cover is taken off the hive. Using a puff of smoke into the center of the inner cover will calm your bees prior to opening the inner cover.
No painting is necessary on this hive body part.
