Effective leveling and removal of air bubbles
Removal of the air bubbles is complete after you have
worked the tool throughout each effective range, the
concrete stops shrinking, and the mortar has risen evenly
to the surface, giving off a light appearance. Gently
remove the operating tool not to leave holes.
NOTE:
Vibrating too long in a single place causes concrete

segregation.
When the coarse aggregates segregates when
•
placing concrete, shovel out the coarse aggregate
and put it where there is plenty of mortar. Then use
the tool on it. Don't leave coarse aggregate in the
segregated condition.
When concreting a slope site, always pour from the
bottom at the beginning. This way the weight of the
freshly poured concrete and vibration will lead to
effective removal of air bubbles. Conversely, if the
pouring is done first from above, the mortar will separate
and eventually slide to the bottom.
