Hello all,

I'm getting some conflicting advice on the best mix to use for setting fence
posts for a 6ft vinyl privacy fence. I've been told that any Quikrete mix
(like the #1101) will set up if poured dry. I've also been told that the
fast setting the fast setting #1004 is far better. Someone even told me that
the non-fast setting will only have half the strength of the red bag, fast
setting mix if poured dry. I'd like to save some money if possible but don't
want to sacrifice strength over the years as this fence will catch lots of
wind over the years.

Wind?

Sorta funny.

I put in a vinyl fence. The instructions said put concrete around the
posts, put 2 pieces or rebar inside the posts, then fill the posts with
concrete. These are 4 or 5 inch square posts.

Those posts aren't going anywhere.
