Dump a bucket of water in the hole and then pour in the quikrete or vice
versa, don't make it complicated. It's vinyl fencing, the vinyl will break
a million years before the concrete no matter how badly you botch the job.


I agree 100% with this. When I put in a 700' fence last summer,
fast-set priced out twice as expensive as regular quickrete, and I have
more time than money. 24 hours isn't too long for me to wait for fence
posts to set.
