1.4. Guidelines for Finishing

Try these first

1. 1.

   What is a power float?

   Hint

   Think about the name and its function.

2. 2.

   How many square meters can a power float finish in a day?

   Hint

   Compare it to manual finishing productivity.

3. 3.

   What is the primary advantage of using a power float?

   • Lower cost
   • Higher productivity
   • More manual control

   Hint

   Consider efficiency in construction.

4. 4.

   Troweling requires blades to be angled, true or false?

   • True
   • False

   Hint

   Remember how each technique functions.

5. 5.

   A construction project requires finishing a 1000 square meter concrete slab. If manual methods can finish 50 square meters per day, how many days will it take? How would productivity change if a power float is used instead?

   Hint

   Compare the rates and divide the total area by the finishing capability.

6. 6.

   If the concrete's surface leaves a footprint greater than 6 mm when tested, what does that indicate about its readiness for machine finishing?

   Hint

   Reflect on the criteria you learned about ready-to-finish concrete.
