Final answer:
In masonry flat work, such as slabs and sidewalks, three essential hand tools are the trowel, used for spreading and smoothing; the edger, for creating rounded edges; and the float, for surface finishing.
Step-by-step explanation:
When working on flat masonry projects like slabs and sidewalks, three key hand tools are commonly used:
- Trowel: A flat, pointed tool used to spread, shape, and smooth concrete or mortar.
- Edger: A tool utilized to create clean, rounded edges along the concrete slab for both functional and aesthetic purposes.
- Float: This tool is used for smoothing and improving the surface density of concrete, typically after it has been leveled with a screed.
These tools are essential for achieving a smooth, professional finish on concrete flat work. Proper use of these tools is also important for the longevity and visual appeal of the completed masonry project.
