1.6. Importance of Blade Angle during Finishing

Try these first

1. 1.

   What is a power float?

   Hint

   Think about the tool used for flooring smoothness.

2. 2.

   What happens when the blade is angled?

   Hint

   Consider how it relates to finishing techniques.

3. 3.

   What is the main purpose of adjusting the blade angle in finishing?

   • To improve the machine's appearance
   • To increase pressure during troweling
   • To decrease machine weight

   Hint

   Consider what effect the angle may have on the process.

4. 4.

   True or False: Power floats can achieve higher productivity than manual finishing methods.

   • True
   • False

   Hint

   Reflect on the productivity figures given earlier.

5. 5.

   Calculate the productivity difference between manual finishing and using a power trowel for a project covering 500 square meters.

   Hint

   Consider how many days it takes for each method based on total area.

6. 6.

   You find that the concrete surface being finished has a footprint of 1/5 inch deep. What steps should you take before proceeding with the power float?

   Hint

   Revisit the benchmarks for concrete readiness.
