1.2. Productivity Comparison

Try these first

1. 1.

   What is a power float?

   Hint

   Consider its function in the finishing process.

2. 2.

   What is the maximum productivity of manual finishing?

   Hint

   Think about how many square meters an experienced worker can finish manually.

3. 3.

   What is the maximum productivity for a power float?

   • 30 square meters/day
   • 60 square meters/day
   • 140 square meters/day

   Hint

   Consider the significant difference between manual and machine methods.

4. 4.

   True or False: The angle of the trowel blades should be kept flat during troweling.

   • True
   • False

   Hint

   Recall the different finishing methods.

5. 5.

   Given a construction site requires finishing 200 square meters a day, calculate how many power floats are needed if each can finish 140 square meters per day.

   Hint

   Think about division and how many floats can collectively meet the demands.

6. 6.

   Discuss an instance where power trowels would be the preferred method over manual finishing in a high-end construction project.

   Hint

   Consider projects where surface finish is critical.
