Pouring cement on Monday for my 21' A602 spinner. Holes are 24" diameter and 4.5 ft deep. Is 4-5 days long enough to harden and then install fan? Thanks for any help. Bill

Depends a lot on your weather. Hot and humid it will suck the water out and set up pretty fast. 3 days would do it. Was pouring a slap in hot August, didn't get enough water on the ground and it was sand it we almost lost it because it was setting up so fast.
