True or False: While machine floating, if the machine digs in or disrupts the level of the surface, stop floating and wait until the concrete surface is stiffer.

Explanation:
When finishing with a power float, you want the surface to support the float rather than be pushed around by it. If the machine digs into the surface or disrupts the level, it means the concrete is still too plastic and the tool is overworking or dragging across a soft layer. Continuing to float in that condition can pull paste into the float, create low spots, rough patches, or laitance, and compromise the finish. Pausing lets the surface stiffen a bit and set enough to support the weight and action of the machine, reducing the risk of creating defects. Once it has firmed up, you can resume with lighter contact and a more even pass to achieve a smooth, level surface.
