1.How do you know when a slab is ready for the power trowel?
Why they ask
Timing is the core skill. Go too early and you tear the surface or trap bleed water. Wait too long and you're fighting it.
How to answer
- Describe checking for bleed water to be gone from the surface
- Mention the footprint test: your boot leaves a light print, not a deep one
- Say you start with float pans before switching to blades
- Note that sun, wind and mix all change the timing on every pour
