Trowelling the concrete surface eliminates large aggretates near the surface, levels
bumps and depressions, and consolidates the surface to make it stronger. The surface
must first be sufficiently cured to support the weight of the trowel. The surface should first
be leveled using a float or vibratory screed. To use the standard finish blades, the
concrete should be cured enough that the operator does not leave a footprint deeper than
about 3mm (1/8 inch).
The ideal way to trowel is to work backward, traveling up and down the slab pulling the
Power Trowel toward you and making elongated, overlapping sweeps (see Figure 13).
This allows you to thoroughly cover your footprints in the concrete as you walk. Work
steadily and patiently, going too fast will result in poor consolidation and an unattractive
finish. Each pass should be made in a perpendicular direction to the previous one (see
Figure 14).

ALWAYS look where you are going. Be aware of any pipes or other
protrusions from the concrete to avoid tripping or striking the blades.
Striking the blades can bend the trowel arms or damage the drivetrain.
